This motor is in my brother's E30 (325is).

First kicked it over 2 nights ago. Not a lot of time for tuning yet and car is not drivable either. Still it fires up and idles perfectly. MS2 Extra Driving stock COP's via 6 x ISL9V5036P3 (VB921 equiv) on 2 Glen's Garage idle boards in wasted spark. One board has 4 drivers, the other has 2 drivers and idle control. Can supply details on request, will publish 'polished' tables when ready...

Some vital info:-

-Crank Sensor is front mounted HALL sensor. (5v is working well) ***UPDATE*** - Having minor random sync losses when cold. Switched HALL supply to 12V made no difference. I am 75% sure these sensors run 12V on the factory ECU.
-Cam sensor is unknown, and is labeled a 'proximity' sensor in my Bentley Manual. (???)
-ReqFuel for stock injectors is 13.5ms (suspect this value is off as 100kpa VE cells are up to 130...)
-Tooth No.1 is 330 dbtdc
-Standard Tach circuit (12v, 1n001 & 2 x 1k) seems to work the E30 dash.
-VANOS solenoid is switched on @ ~1600rpm and off @ ~5000rpm. (Yes, switch off at 5000rpm!)

Engine bay pics:

What output do you use for VANOS solenoid?

IAC2, on @ 1600, off @ 5000. (yet to be dyno checked)

allmost like a mercedes 24v vanos. on 1700 and off 5000

Do you use 20-30amp relay between the output from the ecu and vanos valv?

There'd be plenty of smoke if I didn't....

Hello...have a couple of questions about your setup. I know this thread is kind of old but I'm hoping it's not forgotten...how did you setup tacho output and VANOS control? I'm assembly 1 unit for an m50tu and been having a few issues with the diagrams. Some pics would be nice.

Gonna try posting on msextra.com also.

Thanks for any help.

Hi, is this your final ignition map? Can you post updated if you have? Thanks.
