Trouble with creating a megasquirt base tune

[swolsky98]

Hello everyone, I have recently refreshed my 1997 mazda b2300 5.0 swap. I have added a vortech v1, gt40x heads, anderson b21 cam, gt40 intake that i have ported out, and anderson hi-rev valve springs, and ford performance 60lb injectors. I recently picked up a megasquirt ms2 to tune the truck and I cannot for the life of me to even get the truck to idle. I am looking for any advice anyone could give me. I have been watching videos and trying to make changes for 3 weeks but cannot make any progess whatsoever.

This is the base tune from megasquirt with some values i changed to accomodate the injectors. my base timing on the crank is set to 15 to match tuner studio

Nice... One of the experts should find it. Check back often and watch your alerts.

Here you are, I did not setup the idle settings for you these can be tricky to dial in unless you know the procedure if I set them up in closed loop.
I did setup the AFR, IGN, VE tables for you and scaled them for boost with safe values in the IGN table.

Hey a91what,

I have finallly got the chance to test the base tune. Idk why but when the truck starts it automatically revs to 3k and holds there upon start up. I can get the engine to idle good with the IAC uplugged though. I went in and did the IAC test to manually open and close the valve but when I lower the duty percentage the rpms went up somehow (I changed the IAC settings so its not inverted) so that does not make any sense.
