Megasquirt n spark v.2.2 hall signal problem

Post by Jalamari »

Assembly

-Megasquirt V2.2, with extra code
-Tunerstudio
-opel 2,0X30XE Hall sensor
-distributor, 3 tooth crankshaft ( 6 cylinder motor)
-Board wiring. Hall input hi to lo 12v http://s188.photobucket.com/user/Reiluk ... 1226527278
and spark output, led 17 http://members.shaw.ca/rgustafson/car/M ... -spark.GIF

My problem is that the car wont start. Spark-LED blinks as it should, and Tunerstudio shows about 200rpm when starting. Tunerstudio tooth logger does not show anything. I checked the hall sensor through the hall signal wire, and the signal voltage is 10,7 without tooth, and with tooth 7,8 volts. Is this right or should the difference be bigger with this kind of wiring?
The car ran fine with only injection control. Then I added spark control, but only twirled the ends of the wires together cause I wasn’t sure it was correct. The car started and ran fine for about ten minutes. Then I turned off the engine and redid the wiring, this time properly. I tried to start again, and it almost did before it stopped. After this the car hasn’t started, and the Spark-LED doesn’t light up either.
I replaced the hall sensor, Q2 and Q7 Fets and redid all the soldering of the PCB, the moment the spark-LED blinks on normally, Tunerstudio shows me the 200rpm, toothlogger shows nothing. And the car wont start… What else could have broken?
