98 Ford Ranger, w/99 Explorer 5.0 bottom end. Edelbrock performer heaeds w/1.70 rr's. Crane 2031 cam, SCT 90mm MAF. 24lb injectors.99 Exploer ECM
Tuned via Commando, still having lean/rich issues. Adjusted global pt/ft, but seams to be some confusion as to which way leans or richens. The book, and software (not infront of me atm) seam to contradict each other. 1.0 to1.5 to richen, 0.9 to0.1 to lean ? I need to add a little more fuel, any changes made in commando under fuel seams to cut the fuel off. Right now I am set on 1.5 FTand PT, to make it run under Ford Fuel base programming. Any changes in Commando seam to do opposite of what we need. Cam has 5* timing built in, have changed it to O* to start out. Any suggestions on fuel tables ?

Re: Fuel adjustment
If you're using Special Forces.... 1.5 would be the max rich you can go with the FT & PT.
If you're using Commando, the tables to adjust would be...
1. Stabilized Open Loop Fuel Table
2. If that's not working then you probably need to adjust the MAF transfer function.
