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)
- 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...
