A Turner Performance Chip for the 1992 E36 325i is an absolute MUST-HAVE performance upgrade. This chip was developed on the dyno to increase horsepower and torque from low RPM all the way up to the new 7000 RPM rev limit. Engine management expert Jim Conforti tuned the fuel and spark mapping to maximize output when used with 91+ octane fuel. More power, a smoother engine, and better response are the results. Bang for the buck, this is hands-down the best upgrade to do. The rev limiter is raised to 7000 RPM and the top speed limiter has been deleted.

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).

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

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​
