I'm too impatient to wait on the scanner lol the code came back this morning after a hard start. So on my lunch break just now I flipped the gear on the new dist. 180 and reinstalled according to that guide I linked yesterday. BAM! No code and it's running much better! Still falls on its face at WOT but that could be solved with a fine tune once I can read the CMP Ret. I also noticed my fuel trims were wayyyy better. I've been getting like 10-12mpg so a boost in fuel economy would be a welcome bonus to hopefully getting this solved. Here's a quick video of the UltraGauge screen while I'm running about 3/4 throttle.

Hey, Les I found one that works on Torque Pro! This is as close as I could get without modifying the hold down.

Cool! VERY interesting. Where did you find the formula? Good thing to know.

Please post the formula and how you entered it and I will check it for accuracy against other software on my vehicle. I never had any luck myself getting it to work at all in Torque Pro. I believe there are different formulas for V8 vs V6, but AFAIK they do converge readings at zero.

I actually found it on a Safari Van forum, I think this equation is for a V8 but I'm sure it's very close. I'm gonna have my friend check it against his Snap-On scan tool.
