Hi, After a lot of tests, the solution was a wrong way in the crankshaft sensor... It was working perfect since 5 years ago, but, now sometimes, not syncro. Also I modified the power bat compensation for the dwell and all it's working perfect. It's crazy, with the wires way changed, the timing it's ...

Hi, After talk with Alex, I switch the wires in the crank sensor and now starts much better ! Oscilo read better also in test mode. I am searching if any power supply problem to be down as that in volts. As soon as I see if the power failure it's something with the car loom, I will check again start...

Thanks Phillip,

I will check if I can put voltage compensation to help the dwell after test with this external power supply to power the ECU, like that, not voltage failure in the start phase.

Long time ago I was worked in, I hope I will find the battery compensation in the settings

Well, Laptop in and first tests, and as expected, all it's working fine. When the car not want's to start, the oscilo/crank it's ok, and all sensors, map, temps... working ok. Only one thing looks not normal, when I start the first time, the power batterie was 12-12.3v, but when not start, the gauge...

Hi Again, Yesterday, I tested all the voltages in the temperature sensors and the volts variation in the map in vacum, 0, and pressure and all it's working fine... but not restart if I turn off the engine. I will try to test the voltages also in the moment is not starting to see. But, if the voltage...

Hi, I have a S40 ignition management in a car with a K-Jetronic injection ( all in perfect condition, tuned and controled ) All was perfect running before stop the car to rebuild the engine... Once I finished the project, start ok, but if you stop the engine, you never know if it will starts again.....

Well,
I put the wires in the correct pins and all run ok, now I must work in the map with the engine running.
After 30 kms I can say, I like very much read the air temp values, etc in the laptop and see the ignitions timming is working as I say in the first map.
Thanks for all !!

Hi, yes now is very clear.... but in the moment I put the wires in the connector I talked with the guy sold me the connectors and I taked : 1=a 2=b 3=c Mi mistake was not search a note for the map sensor... Wen I try the different sens of wire, I tell you if now I have a correct values in the map Th...

Yes, one is correct !! I think I see one little problem, I supose I inversed the 5v with the signal, because the 123 in the map sensor is inversed if we look in the loom connector, wen I put the connector in the map sensor, the 1 is the 3, the 2 is the 2 and the 3 is the 1.... the plastic connector ...

Hi stevie,
thanks a lot, I search also in the magneti marelli and I found this...

I say you if it works when my customer comes with the car and I try and test, now he is running with the standard ignition in the car, I mounted the dta without remove the original system.
