Wait your lo is set to 69% and hi to 70%?? So the only time the SAFC adjusts fuel for lo-throttle is exactly when you're at 69% throttle.

Lo should be around 20% throttle, high around 60-70%. Then from 20-69%, the car is reading the lo-throttle settings, and 70 and up it reads the hi.

Use periods please. And then buy a logger at minimal and a WB.

Well i changed it to 30 low and 80 high and it runs alot better. Now i just need to get the percent it changes down but running alot better.
