The MOTIV ReFlex+ is an Advanced I/O Integration module allowing a level of precise control of auxiliary components. In addition, the ReFlex can incorporate external data into the factory DME/ECU in parallel through optional CANbus integration. Utilizing the CANbus option, multiple digital and analog signals can be used by the DME/ECU for safety, data logging, or adaptive tuning features. It is unique in its ability to function as a separate standalone, as well as a parallel module in conjunction with the DME/ECU. The ReFlex provides the most accurate and precise supplementary sequential fuel injection with the ability to control other advanced features all in one place. It brings a new level of control, function, and versatility to tuning any modern-day vehicle. Preset crank and cam trigger for most modern-day BMW engines, as well as fully configurable triggers to be synched on any vehicle application. Configurable to operate on 4, 5, 6, and 8-cylinder engines. 3 Point MAP sensor calibration table makes it configurable for almost any MAP or TMAP sensor. Sequential Port Injection with the ability to sense individual injector failures on 4 to 8-cylinder engines. Built-in Ethanol Content Analyzer. The Re|Flex firmware and XDFs include ethanol compensation tables to scale properly for varying ethanol % based on real-time input from the sensor. 2x Additional Outputs. These outputs have 12x12 resolution tables for control in TunerPro R/T. These can be configured to run as on/off, digital, frequency (25hz), or PID. Boost Control WGDC Methanol Solenoid Control PWM (for use with valves such as the Aquamist FAV and the ProMeth Pulse Valve) Nitrous Solenoid Control PWM Auxiliary fuel pump relay trigger 2x Inputs Ethanol Content Sensor Fuel Pressure Sensor (0-10bar) Oil Pressure (0-10bar) Coolant Pressure (0-10bar) EGBP/EMAP (0-10bar) CANbus (not required) enabled communication for the transmission and receiving of digital signals for fully DME/ECU integrated control of external modifications. The CANbus communications also allow for data and errors to be transmitted to and from the vehicle's engine control computer in order to add safeguards and implement engine trips and fail safes. Logging via OBDII is still fully functional and is not affected at all by the communication with the Re|Flex. Some of the developments underway include: Error reporting to and from factory ECU for unparalleled safety Output WGDC by converting an EWG signal to a more conventional DC output for controlling standard 3port and 4port boost solenoids for use with external WG’s The ability to datalog non-factory parameters such as ethanol content, additional pressure sensor, PI IDC, and more! These features make the Re|Flex the most powerful and safest supplementary and auxiliary controller on the market. However, this is only the beginning. As flash platforms find the need for more accessories to control, the Re|Flex was designed to be updated easily by the end user in order to add functionality as it is developed.

When the first M5 and M6 were brought to the U.S. they were de-tuned from their European brothers and sisters. That was a shame as the cars lost close to 40hp. But adding a Turner Performance Chip will get that lost horsepower back! Jim Conforti tuned these chips on the dyno to boost mid range torque and increase horsepower in the upper RPM range. As a result there is a 48 horsepower increase at 6000 RPM with a new rev limit of 7200 RPM! Conforti achieved this by tuning the car on the dyno, specifically changing the fuel and spark patterns in an effort to make the engine more efficient when burning 91+ octane fuel. Torque increases similarly in the heart of the powerband.

FOR AN EWS DME IN A CAR THAT DOES NOT HAVE EWS-II
See below for a list of common cars and chassis that this chip would be used in.

A lot of times when building a racecar or doing an engine conversion the EWS-II system can get in the way, adding another layer of complexity to the job. Since racecars and engine conversions have been such a big part of our history, we developed a special chip to eliminate the EWS-II system from the Bosch silver 413 DME. This chip is perfect for someone who bought an EWS-II computer without realizing what the system requires. The chip will de-activate the EWS-II code inside the DME thereby allowing you to use it in a car that did not have EWS-II or on a racecar that has the EWS-II removed completely (EWS module and key). It also has all of the benefits of the "regular" Conforti Performance Chips - more horsepower and torque, increased rev limit (7000 rpm), top speed limiter removed, etc. In the past you would have had to buy a non-EWS DME. This chip saves you both time and money. Click here to learn more about EWS-II.

Turner Performance Chips provide the ultimate in performance advantage! Adding a performance chip to your BMW is the easiest and most cost effective way of increasing BMW power, torque, and performance with NO DOWNSIDES. Through years of BMW performance tuning, we are able to maximize power and torque gains for 91 octane fuel used in North America. By making changes in the ignition and fuel maps of the DME we are able to optimize performance with no side effects or compromises. Other changes will make your BMW smoother and more responsive than when it left the factory. Our chips have a lifetime warranty and a 30-day satisfaction guarantee. If for any reason you are not fully satisfied with the increase in power and overall drivability you can return the chip to Turner Motorsport for a full refund. Chips are supplied with detailed instructions and are installed in about an hour. See below for specific information that we may need from your BMW.

Important Note: This EWS-delete chip is not intended to bypass EWS-II or as a workaround for a problematic EWS-II system. With this chip, no EWS-II components can be in the car. In other words, you cannot use this chip to bypass the EWS-II on a 1995 M3 because the EWS is having problems. This chip is only for using that DME in a car that never had EWS-II to begin with.

At its core the PCU is like its precursors and installs in between select sensors and the ECU, adjusting these signals in order to achieve increased performance the stock programming is unable to approach. However, what sets the PCU apart is its integration into more than just the fundamental boost sensors but also additional connections--inclusive of OBDII. The result is a more capable system that can do so much more than just increase power. Live monitoring of vehicle health via logging, customizable gauges, and code reading/clearing, among others, are now possible ensuring a seamless tuning experience even a novice can be comfortable with.

The Dinan PCU is controlled by a free Bluetooth app, available for both iOS and Android, and is home to all the potent features the device offers. Equipped with 5 different pre-set performance levels, in addition to stock, you can choose to select your desired output and enjoy more power for a true install-and-forget experience, or you can opt to engage in the more advanced features at your fingertips. Boost by gear customization, as an example, allows you to limit power delivery as you see fit in lower gears ensuring optimum traction and a perfect launch. Where the PCU shines however is in data acquisition and monitoring that gives insight into the vehicle's overall health and makes certain your tuned vehicle is always running at peak potential.

Safety and reliability have been cornerstones of the Dinan brand for generations and not only does the Dinan PCU not hinder any factory safeguards or emissions controls but incorporates its own safeties as well. Going one step beyond our own internal protections, the PCU also grants the end user the ability to monitor up to 20 different engine parameters in real-time via customizable in-app gauges for verification of worry-free operation. Those same parameters can also be logged/viewed in app (or exported to CSV) for further scrutiny if desired.

All told, the Dinan PCU delivers more power and more features with improved reliability and drivability than ever offered before. Performance without sacrifice is alive and well!

SKU variations / Warranty: The Dinan S58 PCU is available with a standard 2-YR product-only warranty (Dinan S58 PCU–D440-0200) or a factory matching 4-YR/50k mile warranty (Dinan+ S58 PCU–D440-0200-W) that covers both consequential damages as well as labor reimbursement. Functionally, the units are identical but carry different warranty terms. In the case of the factory matching warranty Dinan+ PCU, the warranty ONLY applies to the first VIN the unit is installed on. Successive VIN’s will not be granted warranty coverage from Dinan.

If you have an M3 engine and want to use the 21.5 lb/hr injectors (pink top, stock on the 2.8 M52 and 3.2 S52) we have the perfect chip for you. Instead of changing to the smaller 17lb injectors or upgrading to the full 24lb, you can use the injectors from the stock 3.2 M3. They are in-between 17lb and 24lb, allowing a little more fuel to compensate for intake and/or exhaust upgrades.Perfect for running headers with an intake! There are plenty of surplus 21.5lb injectors out there (we sometimes have them too, check out Used Parts section).

It's usually not necessary to use bigger injectors but this gives you another option in your engine planning. This software covers almost all of the popular bolt-on upgrades, including the larger HFM (Euro or 540). Choose the mods/upgrades from the list below.Turner Performance Chips provide the ultimate in performance advantage! Adding a performance chip to your BMW is the easiest and most cost effective way of increasing BMW power, torque, and performance with NO DOWNSIDES. Through years of BMW performance tuning, we are able to maximize power and torque gains for 91 octane fuel used in North America. By making changes in the ignition and fuel maps of the DME we are able to optimize performance with no side effects or compromises. Other changes will make your BMW smoother and more responsive than when it left the factory. Our chips have a lifetime warranty and a 30-day satisfaction guarantee. If for any reason you are not fully satisfied with the increase in power and overall drivability you can return the chip to Turner Motorsport for a full refund. Chips are supplied with detailed instructions and are user-installed in about an hour. See below for specific information that we may need from your BMW model.

Note: we will not be offering this software for use with cams. More aggressive camshafts require the use of the Bosch 24lb injectors. The 21.5lb injectors are maxed out when used with cams.

Additional Options:

  • EWS-delete: required when using the silver 413 ECU in a car that does not have EWS (all chassis manufactured before 12/94). If you will be using this chip in an EWS car (1/95-later) you do not need EWS-delete as nothing EWS related should be changing.
  • Speed sensor delete: for an E30 with an M50 engine conversion, the signal from speed sensor does not make it to the DME, causing a low rev limit. We remove the need for the speed sensor signal to reach the DME.

This S52 OBD-I Performance Chip applies to the following BMWs:
Any S52 engine converted to OBD-I electronics
1985-1992 E30 S52 conversion
1989-1994 E34 S52 conversion
1995* E34 S52 conversion
1992-1994 E36 S52 conversion
1995-1999* E36 S52 conversion
* - 1995-1999 model years may have EWS-II activated. Pay special attention to production dates and ECU numbers.

Read other's impressions:
"I went with the Conforti that I bought from Turner and am very happy with it. There is no noticeable (to me) change in fuel consumption. I have slightly better pop in lower gears where , gawdknows, the car really needs it and the car certainly pulls faster and stronger at the top end." - Taylor, Montreal, Canada.

"I have just installed the Conforti/Turner chip, actually increased my gas mileage by 1 mpg, but the power curve is much better and the movement of the point in the RPM bad where the engine limits itself is so much nicer. I am very happy with the change." - Rick, California.

"I tried Dinan and BavAuto�I like Jim C's the best." - Joe, Connecticut.

The E36 M3 benefits greatly from a TMS Performance Chip. Although premium fuel is recommended by BMW, the car is not optimized for it. Significant horsepower and torque gains can be had by switching to a Turner Chip and using 91+ octane fuel. Tuned specially for the E36 M3 on the dyno with Bosch expert Jim Conforti, this chip provides a smooth power delivery from low RPM up all the way up to redline. Conforti achieved this by altering the fuel and spark maps along with the cam timing to take full advantage of premium fuel. The result is a big boost in power, more usable torque, and a smoother-running engine. The rev limit is raised and the top speed limiter is removed. There are NO downsides to installing a TMS Performance Chip; it is FREE, easy-to-install horsepower.

The DINANTRONICS X is the newest installment of the highly successful Dinan foray into inline tuning modules. Like its predecessors, it is a highly engineered piece of computer hardware and software that enhances engine performance to levels the stock programming is not allowed to venture. It does this without affecting long-term reliability or the functionality of onboard diagnostic systems when run under recommended operating variables. Unlike its predecessor, however, the DINANTRONICS X is Bluetooth smart and offers convenient access to the adjustment of power levels directly from the palm of your hand. A further advancement beyond its entry-level little brother, the DINANTRONICS SPORT, X connects to additional inputs and/or has a more refined tuning strategy that yields more power as a result. For those that do not wish to (or can't) alter their stock ECU with a more robust engine flash the DINANTRONICS X is a perfect alternative to satiate the craving for "more". Whichever level of engine tuning is ultimately chosen you can be sure to be pleased by the result. The Dinan Difference is possible by employing a full staff of talented engineers that are well rounded in many facets of automotive engineering and backed by a wealth of hands-on knowledge. Stemming from diverse backgrounds not only on racing teams but on standard factory production line vehicles, we have seen it all. Manipulating these signals/maps with an adept hand, all the while keeping an engine running at its best and with the most reliable power, is what Dinan is all about. NOTE: D440-0153 does not apply to the 2020 M340i. Please use D440-0152 (ES4499647) for that specific application. Features: More Power: Max gains of up to +60 HP and +91 lb-ft TRQ (Crank); +55 HP and +80 lb-ft TRQ (Wheel). Bluetooth smart (Android and iOS Compatible). 7 power levels and a bypass setting to choose from. Smooth and predictable power delivery. On-board diagnostics and factory safeguards are maintained. Unaffected by dealer factory updates. Plug and play installation. 14-day satisfaction guarantee. 1-year limited warranty - DINANTRONICS X does not carry the factory matching warranty that Dinan is known for. DINANTRONICS X's warranty is a 1-year, product-only warranty, that does not cover consequential damages or labor reimbursement.

Horsepower Gain Up To: +22 @ 6,000 RPM
Torque Gain Up To: +20 @ 4,000 RPM
New Rev Limit: 7,000

If you're looking for a significant bump in power you need not look any further than a TMS Performance Chip. Designed to maximize the advantage of premium fuel, Performance Chips safely alter the fuel and timing maps which results in more power and a smoother engine. These chips were tuned by Jim Conforti on the dyno with fantastic results. What you feel is more power starting at 3500 RPM and continuing up to the new rev limit of 7000. There is no downside - only an awakened engine and a car with new life!

Performance software is the key to unlocking the power that BMW left on the table. For the US market the factory software is set for 87 octane fuel. But the engine is capable of producing so much more! We make adjustments to the fuel, ignition, and camshaft timing data at part throttle and full throttle to take advantage of premium 91+ octane fuel. We dial in the settings so that more power is made at all RPM. What you'll notice is more power and torque at wide open throttle and even when driving around town. The engine will run smoother with better throttle response and less hesitation. We keep the factory safeguards in place so there is no long term engine damage or negative side effects. It's not just gaining power back - it's better than when it left the factory!

We're also able to tune for all of the popular M50 engine upgrades -

  • lightweight flywheel - adds 100 RPM to idle
  • stock E36 M3 camshafts - these work GREAT for producing more top end power. We adjust the maps to take advantage of higher lift and duration
  • sport exhaust - additional tuning for cat-back exhausts​

BMW used two different engine harnesses, please confirm if you have type A or B before ordering. It’s sufficient to locate only one of the sensors because the plug type is always the same for both of them (pictured above in the second photo). Harness Type A - Third Photo/Harness Type B - Fourth Photo RaceChip is the largest chip tuning company in the world! Their products are made in Germany and rigorously tested on the Autobahn. RaceChip offers the next generation of performance tuning. It allows for up to 30% more Horsepower and 20% better Gas Mileage with a very simple installation process. Unlock the untapped performance of your BMW engine with peace of mind from RaceChip. S: 5 Tune Mappings +51 HP +70 lb-ft Torque Up to +15% MPG Includes everything you need for installation, down to the cable ties. RS: 6 Tune Mappings +63 HP +88 lb-ft Torque Up to +20% MPG Includes everything you need for installation, down to the cable ties.

XLR Throttle Controller: RaceChip developed the new XLR to increase responsiveness on the road. Their innovative throttle tuning system lets you tune your engine’s reactions to your taste – choose from 7 separate stages (Eco+, Eco, Neutral, Sport, Sport+, Race, and Race+). Your engine’s performance isn’t affected by RaceChip XLR, but you can access it more immediately and directly. Experience significantly sharper responses for yourself – no waiting for the message to get through or frustrating “pauses for thought”. And the best thing: installation is simple and requires no specialist knowledge. Try it now! The Brainbox: The Brainbox is the nerve center of XLR and controls the processes needed to optimize throttle response. The Brainbox’s compact size (ca. 70 x 80 mm) allows it to be fitted easily in the footwell of your vehicle. As it is so flat, it does not restrict the driver’s legroom at all. It can be fixed almost anywhere in the footwell, for example in existing slots or vents. The Controller: The XLR Controller allows you to choose between 7 stages: Eco+, Eco, Neutral, Sport, Sport+, Race and Race+. Each stage sharpens your car’s throttle response a little more, until in Race+ it’s like a thoroughbred sports car. You can mount the Controller anywhere in the car so that it’s in the right place for how you want to use it. The size and design mean it fits right in with the rest of the interior and the other control elements.

With the CSi BMW really turned out one of their finest engines. A touch more tuning by Bosch Motronic expert Jim Conforti yields just a little more punch from the big V12. Conforti altered the fuel and ignition mapping to take advantage of premium fuel (91+ octane). Although the 850CSi is required to run "premium" anyway, it is not optimized for it. Changing these settings results in more power and a smoother-running engine.

Turner Performance Chips provide the ultimate in performance advantage! Adding a performance chip to your BMW is the easiest and most cost effective way of increasing BMW power, torque, and performance with NO DOWNSIDES. Through years of BMW performance tuning, we are able to maximize power and torque gains for 91 octane fuel used in North America. By making changes in the ignition and fuel maps of the DME we are able to optimize performance with no side effects or compromises. Other changes will make your BMW smoother and more responsive than when it left the factory. Our chips have a lifetime warranty and a 30-day satisfaction guarantee. If for any reason you are not fully satisfied with the increase in power and overall drivability you can return the chip to Turner Motorsport for a full refund. Chips are supplied with detailed instructions and are user-installed in about an hour.
