MS2 Basic starts then immediately dies
I recently bought a used Rev-built MS2 here on the forums to upgrade from my MSPNP.
The car ran pretty good on the mspnp but the ecu had a problem with random resets while cruising. Only mods are Toyota cops in batch fire, Five-o 550cc injectors, Coolant reroute, and an LC-1.
I connected the ecu, lc1 to the ecu and map line. I adjusted the req fuel for my injectors and opened the idle screw on the throttle body all the way up. The car cranks, begins to start, revs to about 1000 rpm and then immediately dies.
I've tried adjusting the fuel in the idle cells, trigger angle, a few different idle settings but I'm not sure what else to try.
The composite log looks very similar to what it was MSPNP, however I don't really know how to interpret it.
I attached my MSQ below.
Thanks for the help - Mike

here's a question: what would normally make a car stall?
Is it possible it's leaning out and unable to continue running? How do you possibly imagine you could solve this problem? Maybe by adding fuel to your start-up enrichments?
Or maybe your idle valve is closing too fast? I wonder how you could find that out? Could you hold it open longer? Possibly? But how does one do that? Through tuning a completely programmable aftermarket ECU? posting online?

Its going into fuel cut above 400rpm.
I opened his basemap to try and find the source of the fuel but it is so messed up, I don't know where to even begin.
It is like someone with absolutely no idea to what he was doing just tried random values everywhere.

Shouldn't the car be able to start even if the idle valve was closed, if I as I said in my first post opened the idle screw all the way open? Or should still be able to start by feathering the gas pedal once it begins to start.
The MS2 has far more menus than my old MSPNP, sorry for being a .
