Okay when I bought the car the MAFT was already adjusted, but not perfect. I use a ton of gas. Wideband afrs at Idle & cruise 13-14 and WOT is 10.5-11. My questions are as follows:

1.Excluding the AUX knob and switches, the 4 dials on the bottom left to right are base, idle, mid & wot right?

2. When I messed with the dials to try straightening out my idle AFRs, I tried each knob from right to left to see which one effected my idle, and couldn't tell so I reverted all the knobs to their original location, after the car is super rich wot: 8-9 w/ back fire. When I adjusted the knobs I turned the car off each time. Why am I suddenly so rich? Does the computer have to relearn?

Any other tuning advice would be great. I have ECUflash but not using that until I am least comfortable with MAFT. Thanks
