Ok, so I was talking to Ken the other day and he was telling me that I should change the tire rpm ratio on my Mach due to my non stock rear rim/tire set up. So after inputing my info on a tire rpm calculator, I got 781rpms! Well, this morning, I plug in my Xcal, set it at 780rpms, leave everything else as is, and uploaded it. Well after the Xcal did what it had to do, I unplugged it, turned the car on and it revved to 1500rpms and stayed up there for a few seconds. It then finally dropped down to about 1100-1200rpms and stayed idling there. I revved it up and the rpms stayed hanging for quite a while, then eventually dropped back down to the 1100-1200rpm mark. And for whatever reasons, the "O/D Off" light was blinking!? What's up with that? Is it because my Xcal is a 9400 model and NOT a 9415 SF? Or is there something else going on that I'm not aware of? TIA! :cheers: :)
