at a loss

Unread post by tufgriz »

So about 5 years ago I built my current fox running 06 take off 24lb injectors using a c&l 76mm mass air and it ran pretty good. Decided to swap to microsquirt and ran it for around 4 years, which brings us back to current. I decided to swap back to my a9l and use my quarterhorse I picked up a couple years ago and I can not get the car to run normal anymore. ive gone simple to start and used the c&l transfer numbers, 24lb numbers from efidynotuning and turned off the three smogs. and it just goes lean. Ive gone as far as turning only smog stuff off and just using the MAF as is with being calibrated for 24lb, used stock maf and adjusted injector settings and still the same. Currently with stock meter and 24lb injector settings I have to add around 50% to the maf curve to get afr around 15 (running a wideband as well as the narrowbands). What or where can I look? Car has trickflow upper and lower, lunati cam (clone of tf1) brodix st 5.0 heads. Thanks

ok, so here is a tunerpro bin and datalog using the standard files for tunerpro. I do not want to try and use your modified file until I get things figured out
