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.

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!

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.

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​
