Default 1997 Mustang M90 swap

Hey Joe,

Thanks again for your help! Here is the current tune and datalog I have. I'm almost done dialing in the maf curve. I'm currently open loop full time. I don't have to smog the car! My current mods are 94-95 sc,30lb injectors,255 fuel pump, 90mm lighting MAF, front mount intercooler,Stock gears and bottom end. The car rides great!My concern is spark and timing. How much timing can I advance? Also, when light cruising I see 14.6-15.5 and trims appear to be close. Have not tried closed loop, been using the wideband. But any advice with the overall tune please feel free.

Thanks,
Joe

Looks like the maf curve needs a bit more work. The afr should be steady when you rev it up slowly. Tune in closed loop. The afr should be right around 14.7 at part throttle.
