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 park 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.

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.
