Lean hesitation with cold engine TBI

At those temps it's probably not a fuel table and it's Closed loop by then. As Fast mentioned it may be AE TPS and AE MAP.

One thing that helps and some people still overlook Stoich AFR! With E fuel it's 14.12 and when we had none E fuel it's 14.7... this is all it takes for a lean warm up issue!

I am running gas with 10 percent ethanol that is what is available mostly unless you get premium at some stations. I'll try bumping up those ae map & ae tps values. Should I start with one or do both at the same time? Thank You

if you dont have a stoich setting for it to go off of, you can just bump your injector constant or base injector whateverthehell, its pretty much the same, that's what i did with EE.

drives me nuts trying to get it close here on any vehicle, i have a variation of 0% to 15% ethanol in our local pump gas, which is fine if im near home (i've determined which station is 0% in the premium pump), but if i fill up somewhere else i can feel the difference.

only real solution is to run it a bit rich and just let 'er trim for cruising economy when its running 0%. it's not like it minds a bit of extra fuel in other situations anyway.
