BMW E30 Performance Chips: 1985-1995 Cars

Our most popular product, hands down! Most of our Performance Chips have been developed by Bosch Motronic tuning expert Jim Conforti, with a few custom-tuned by TMS on our in-house Dynapack chassis dyno. They provide the ultimate in performance! Adding a performance chip to your car is the easiest, most cost effective way of increasing your BMWs performance with NO downsides. TMS performance chips are supplied with detailed instructions and are user installed in about an hour. The performance chip optimizes ignition timing and fuel curves which results in increased horsepower and torque. We have dyno tested these chips and compared it to all the others and found it to provide the most horsepower and usable torque. Must use 91 octane or higher gasoline. All chips are warranted for as long as you own your BMW and also come with a 30 day performance guarantee; if for any reason you are not fully satisfied with the increase in power and overall driveability you can return the chip to TMS for a full refund.

E28 528e, E30 325e Turner Motorsport Conforti Performance Chip (more info)

The 2.7 liter inline-6 is a torquey car, however, performance drops off greatly after 4000 RPM. With a TMS Performance Chip power is boosted at all RPM but most importantly in the upper RPM. The car really feels more alive! This chip was tuned on the dyno to yield as much performance from this engine as possible and still maintain its strength and durability. Jim Conforti tuned the fuel and spark maps to take advantage of 91 octane gasoline. By making the engine more efficient with this fuel, gains in horsepower and torque are achieved as well as making the engine run smoother.
NOTE: your car may have a replacement DME ending in 021. Our chips will work in this replacement computer as long as the existing chip is not soldered.

Horsepower Gain	+ 24 @ 4500 RPM
Torque Gain	+ 28 @ 4500 RPM
New Rev Limit	5300 RPM

Free shipping does not apply to this chip.

Need to breath more life into your engine? Add a TMS Performance Chip! These chips were tuned by Jim Conforti on the dyno to maximize the engine's efficiency when using 91 octane gasoline. The result is more horsepower and better torque - especially in the mid-range of the RPM band. The car really feels more alive!

Horsepower Gain	+ 12 @ 5500 RPM
Torque Gain	+ 15 @ 2500 RPM

E30M3 2.3-liter Turner Motorsport Conforti Performance Chip (more info)
Adding a TMS Performance Chip gives you the biggest bang for your buck! Jim Conforti tuned these chips on the dyno to boost mid range torque and increase horsepower in the upper RPM range. While not exactly producing V8-levels of torque you will definitely like the power increase across the rev band. The best thing is that there is NO downside to installing a TMS Performance Chip. Turner Motorsport has been in the BMW chip business for close to 10 years and all chips are dyno-tuned to achieve optimum performance and safety. As an added feature, the top speed limiter is removed. Premium 91+ octane fuel is required.

Horsepower Gain	+ 24 @ 7600 RPM
Torque Gain	+ 19 @ 6000 RPM
New Rev Limit	7800 RPM

E36 M3 3.0 and 3.2 Turner Performance Chip for 21.5# Injectors (more info)
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.

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.

Options

EWS-delete: required when using the silver 413 ECU in a car that does not have EWS (all chassis manufactured before 12/94)

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.

EWS-Delete Chip For Bosch 413 ECU with silver label.

FOR USING AN EWS DME IN A CAR NOT EQUIPPED WITH THE EWS SYSTEM.

A lot of times when building a racecar or doing an engine conversion in an E36 the EWS-II system can get in the way, adding another layer of complexity to the job. Since racecars and engine conversions make up the bulk of our in-house work at TMS, we’ve developed a special chip to eliminate the EWS-II system from the 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 the car in an engine conversion (E30 owners with M50 engines!), or on a racecar that has the EWS-II removed completely. 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 track down a non-EWS computer. This chip saves you both time and money.

Performance Chip with Speed Sensor Delete (more info)

Performance Chips with Speed Sensor Delete

Pretty much all BMWs use a speed sensor to monitor rpm, ABS and traction control/ASC operation, windshield wiper speed, cruise control and of course the speedometer. In fact, the speed sensor is one of the most vital sensors on the car. The DME relies on the speed sensor signal to set the maximum rpm in each gear. Problems can arise if you have re-wired the car for racing use or with an engine conversion. Some of those problems are:

time-consuming re-wiring of the car during engine conversions or when building a racecar harness
low rev limits in each gear
installation of data-acquisition systems no longer use the speed sensor signal

What we have done is remove the lines of code in the chip that require the speed sensor signal. Instead the DME relies on the specific parameters and data points within the chip itself. The speed sensor itself remains installed in the differential cover since other parts of the car require its signal. This is not a catch-all answer to every problem that crops up with racecars or during a engine conversion. But like the other parts we have developed, it makes the job – and life – a lot easier.

NOTE: the speed sensor is different than the top speed governor. These chips DO remove the top speed governor, like all of our normal Performance Chips, but these chips are intended for people who have no use for the speed sensor signal.

You can add the EWS-delete feature to these chips as well. Because of the different combinations and variables with these chips it is strongly recommended you contact TMS for further info and ordering. Prices start at $299.
