Summary of change:
An 1988 BMW E30 327i (stroker using super ETA bottom end, with a 325i head), stock everything else for now... Using a VEMS V3.3 ECU, stock 60-2 wheel and CLT temp sensor, IAT from a VW, and a TPS from a 5/7 series automatic BMW. Using original engine wire harness. Running 19# high-z injectors. ECU is running Firmware version 1.0.71. ---- May. 22 2008 Update... The BMW is now turbo. I decided to remake the entire wiring harness for the motor. The old harness was pulled and stripped down to the bare minimum for the remaining functions (starter, alt, clt gauge for cluster, etc). A new engine harness was then made with all necessary (and new) options. - CS: Stock 60-2 Wheel and VR sensor - Cam sync: Custom made using a magnet and hall sensor from an early VW VR6. http://www.vems.hu/files/MembersPage/Sascha/E30-camsync.jpg - Injectors: 6x Flow matched 620cc High-Z - Ignition: Stock VR6 coilpack - CLT: Stock BMW Coolant sensor - IAT: VW VR6 IAT (Bosch) - IAC: Stock BMW 3 wire unit. Pin #1 - Stepper A, Pin #2 - 12VDC, Pin #3 - Stepper B - Knock: Knock sensor mounted to a custom bolt located at the back of the block just under the head by cyl. #6 Will not be used for tuning. If knock sensor can be tuned properly (by using det cans for accuracy) will be used as a safety measure in case of a bad tank of gas) - Launch Control: Analog Input A. ---- Went and did some tuning... 374whp @ 18psi on 91 octane. http://i31.tinypic.com/357rfj9.jpg ---- Back to MembersPage/Sascha
