89 Foxbody ON3 Turbo Tuning Help!

[Ncarter]

Hi, I,m using Microsquirt software and an Innovate MTX-L + Wideband to tune my car. Having an issue running around 2K RPM and it is showing 22:1 AFR on the Wideband but Microsquirt is does not read it correctly. It is showing 9:1 and the car is starving for fuel. The car is running extremely lean and we have tried calibrating the Wideband to the Microsquirt software and that didn't fix the issue.

Attached is a datalog from my most recent drive. If anyone has suggestions on how I can fix this please let me know.

What else is done to your car engine ? What size injectors are you running ?

Hi 90sickfox,

I have a base On3 turbo kit so rated at approximately 6lbs of boost. It came with 60 lb injectors and a 340lph fuel pump. Only other mod is a 3:73 gear.
