Hi!
I am sorry for the inaccurate title but I have many questions and many problems.
My intent is to control only the ignition with the MAP.
In a first time I tried at the bench the engine with a 0.3 v board, all okay!
I use a GM 4 pin module with a dumb coil (from an aprilia sr).
When I installed NO2C on the bike I had a problem with rectifier, and BOOM!! a tantalum capacitor exploded (C4), not the first time in my life with speeduino.
I replaced it and I added diodes on the + 12v power supply. I tried to get the engine running and BOOM!! a second time explosion. Replaced again and I tried now to get the engine running with battery supply only, nothing exploded but I get only "half sync" and zero rpm, I tried different arduino, vr board but nothing..
I soldered a new board, I get the engine running with battery supply only, now engine get running without exploding something, but after 10/30 seconds the engine stops because speeduino no longer controls the spark, spark led off.
If i try to start the engine I can saw in TunerStudio rpm but speeduino's spark led are off.
To get Speeduino working again I need to disconnect the wire beetween speeduino and the GM ignition module.
Setted to "going low"
I ask you for some advice to understand what the problem is for the first NO2C, to understand what to check to restore its operation and how to fix the second problem.
