The TMS Performance Chip for the 735i/iL is designed to
produce large quantities of torque in a very usable RPM range. Jim Conforti
tuned these chips on the dyno and altered the fuel and spark parameters to get
better output. The result is over 20ft-lbs of torque gain at only 2000 RPM and a
broader power band all the way up to redline. Installing a TMS Performance Chip
is a safe upgrade even on high mileage cars as the changes are made to optimize
the engine for premium fuel (91 or higher). The top speed limiter is removed and
the rev limit is raised.
If your car is a 1985-87 735i (E23 body), we need to know
the part number of your car's ECU. If the ECU ends in 059, we need to know the
number of pins on the original chip.
For a 1989-92 735i/iL (E32) we need to know if your car is
a manual or automatic transmission.
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. Where the stock V8 seems
to fall flat above 5500 RPM, the adjusted fuel and spark maps deliver more
horsepower to keep the engine pulling all the way up to the new 7000 RPM rev
limit. 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.

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 redline. There is no downside - only an awakened engine and a car with new life!
For the 750iL we only need to know which computers were installed on your car. Please check the ECU number located on the computer's cover and pick the appropriate option in the box below.
