Summary of change:
'''Introduction''' This page has just started, I will be editing and adding a lot of info for the past progress and what I have done so far, the engine was previously turbo'd and tuned on its stock internals & engine management (MS43) by myself, I recently decided to build it completely and go full standalone. So far: The engine is at the machine shop being built, I took the stock harness out of the car and modifying it to fit the ecu, details soon. //I will remove this introduction once I feel the documentation is complete or I added enough information// ---- '''Car''' * BMW E46 330i '''Engine''' M54B30: * Inline 6, 2979cc, double VANOS, Al block & head * Bored to 84.50 mm for CP forged pistons 8.5:1 * SP components con rods * raceware main and head stud kits, block timeserted * Cometic stock thickness HG * GT35R 0.63 turbine with 50mm BOV, 38mm WG, 600x300x76 mm IC * 2.5" before IC, 3" after, custom piping ---- '''VEMS V3.6''' * IGBT: 8 * LCD: Y * Knock sesors: 2 * EGT: 2 * Flyback: 30 v * MAP: 400 kPa * No SD card, no 1-wire, no PS2 * Trigger ** primary trigger: HALL sensor 60-2 mounted on the block ** secondary trigger: HALL sensor (intake cam) ** '''third trigger: HALL sensor '''(exhaust cam) Actually, commonly the exhaust cam must be used as secondary trigger (if the intake has multiple pulses evenly spaced it's not suitable for secondary trigger, but still suitable for third trigger). No big deal as it can be triggerlogged and than swapped easily. However '''VERY IMPORTANT: write in the order comment: HALL,HALL,HALL, that is thirdtrigger=HALL''' so you get the third trigger wired to econoseal pin (not hidden inside). **//Above info are taken from BMW engine manuals// Note on HALL & VR sensors: Measure resistance for each sensors (both VR and HALL typically has 3 pin. 2 pin is rare, but that is always VR). If you find 2 pins which measures same resistance in both directions (normally between 300..1400 Ohm) that is VR, otherwise HALL. ---- '''Wheelspeed''' Concerning the wheel speed input1 (EC18-8) & wheel speed input2 for traction control, I would like to have more info about it, specifically regarding the input signal: * the ABS wheel speed in sensor is VR, it goes to the ABS control module * this control outputs a processed square wave that I think varies from '''0-~10V'''. Can I take this input directly to 18-8 or do I take the input from the ABS sensor directly? ** 0-10V is good for the wheelspeed input (which has resistor and diode protection). ** Tapping the ABS sensor signals is NOT recommended, and that would require VR-to-HALL adapter anyway ---- '''IAC''' Already hooked the IAC open and close signals to injector outputs * sounds good, just list them exactly... ---- '''Electronic Throttle''' I am still not yet done with the build, meanwhile, I was very happy to see the new firmware 1.2.14 implementing ETC. I updated the v3 to 1.2.15 and here is a plan for the ETC: In BMW the electronic throttle body is called EDK, and the pedal module is PWG '''EDK''': 6-pin module: 1. TPS signal 1 BR/VI: 0.5v @0% to 4.5v @100% 2. Power BR/WS: +5v?? 3. Motor Drive 1 GR/WS 4. TPS singal 2 BR/BL: 4.5v @0% to 0.5v @100% 5. Motor Drive 2 BR/SW 6. GND BR/GR '''PWG''': 6-pin module: 1. GND 2. GND 3. Power 2 GE/GN: +5v?? 4. Signal 1 WS: 0.5v to 4.5v 5. Power 1 GE: +5v?? 6. Signal 2 WS/GN: 0.5v to 2v '''Plan & questions:''' * TPS signal 1 to 36-1, signal 2 to analog channel 6(18-6) * Pedal signal (driver's wish) to analog CH 1&2 (18-16&3) * 2 power signals to EDK & 2 to PWG, are these confirmed +5v so should I have them all from TPS Supply (36-29) or +5v (36-28)? Or do I take the throttle body power from TPS supply & the pedal from +5v? * 3 GND to 36-26 * Throttle body motor drive: Which output should I use?? Stepper outputs (I have the 4 of them free) or Ignition outputs (Only 2 left, 1 was reserved for DISA valve & other may be for boost control) ** I also have to P259 channels free, they are fitted with FETs as I received the box with four of these to drive the VANOS but I used two only '''NOTE''' * Using ETC will use the three analog in channels left, so now I have no in for any additions I might need (like oil T or P)
