    Whodwho megasquirt M20B25 base tune?

    Does anyone have a base tune / map for the whodwho megasquirt? I'm running on firmware 3.3.3, which I think was the firmware of the original base tune. whodwho

    If so, please PM me maybe drop a google drive link it would be greatly greatly appreciated. I'm got the car running on the whodwho PNP but I would like to just have all the parameters set up nice before I start tuning. I loaded the one from diypnp and my tach output is wonky and I had to change the default MAP sensor for it to run well, I'm just worried I might miss something critical or be slightly off etc. So it would be nice to get a hold of that base tune.

    Bump. Does anyone have screenshots from any M20 base tune? I'd like to at least review and make sure nothing I have is super far off.

    I've gotten to try tuning idle and revving,I have some stuff sort of figured out but now I'm having a problem if I try and start the car while warm, it doesn't want to idle unless I hold revs for a few seconds. If I just let it start, the engine starts then the revs die and it dies. It doesn't do this on cold starts. I currently have it on open loop idle, not sure if I should just try tuning closed loop but I'm not sure how you tune that at the moment.

    And if nobody has screen shots of a base tune, maybe just any sort of N/A M20. Mine is a 2.8 stroker. I would appreciate any help.

      Sorry just seen this, still getting used to the new forum layout. The original tune will be on the disk that was sent with it, if you don't have the disk I can send it in the morning.
