    MS2E Inverted Spark ??

    So the car was running decent, but then started idling like absolute crap.. idk what possessed me to change it over to Inverted spark, but when I did, the car started, idled, revved as if it was on a stock ECU.. perfect..

    30 seconds later the ignitor was burning hot and toasted... So Im thinking Inverted spark isnt the way to go.. But why would it run so good with it, but not without it?

    Im just getting started, running Lex's N/A BP 230cc msq with the injector values changed to the 360s for now (still need to swap the 460s in)

    Any ideas? or anyone have an MSQ I could look @ for basic settings?

    Tino, setting that to inverted just sets when the ignitor is turned on so leaving on inverted will burn your ignitor up since it is keeping it on for a very long time (a very extended dwell) and it affects your timing.

    Did it run fine and then all of a sudden not idle? What happened around the point that it started to idle poorly?

    Also did you set your base timing?

      one of the most important features of the megasquirt is the ability to create a log of it running. since people like lex and I can look at it and tell alot about whats going on.

      post up a log of it idling for a few minutes as well as the info lex asked for and im sure we can figure it out.

        It was running fine and then all of a sudden not.. Base timing is set @ 10*

        I think I know what I did wrong tho. I was playing with some other MSQs and must have just mixed something up.

        I went back to square one again re burned the 230cc MSQ and just changed the Req. Fuel .. now its good .
