Let me introduce myself as it is my first post after several weeks browsing.
I own an open prototype fitted with a V6 24V (66302) coming from a 164.
It is a 600 Kgs car running with roughly 260/270 HP, not so bad if we take the power / weight ratio. Gearbox is FT200 Hewland, purely destinated for the track !
My concern today is that i am looking for the electrical diagram or schema of the Bosch Motronic M1.7 (164).
Would somebody know where i could find this on the web ?
Here are some pics of the car, it is a Lucchini prototype from 1992, the engine is the 3.0l 24V - 66302 currently open to solve a head gasket problem. I have to find the cam lockers to set the timing belt correctly ...
I am sorry but i have no pics of the car with the body fitted for the time, but i'll keep you awake on the subject
Yes as you can see i also own a GTV6 2.5l (and BMW CSL Grp5 ...)
The car fires only on the cylinder #3 and very bad spark on the others when i disassemble the coil stick with the plug from the head.
The trouble occured after i tried to connect a Stack tachometer on the - wire (secondary) of one of the coil. I hope i didn't burnt the ECU.
I would be surprised as i disassembled it and i can not see any components burnt or burst. I must search again but it drives me crazy.
I check all the wires and so one, i suspect a grounding somewhere on the high voltage but where ?? (the tacho is now disconected of course ..)
Anybody would know which pin out n# it is to connect the diag light on the ECU?
EDIT : STEVE KINDLY ANSWERED ME; PIN 8 for the Diag light, Pin 74 for the Tacho.
