Quote from WillLennon on June 19, 2020, 6:42 pmAnyone willing to look at a few data logs? I have a 30 sec idle log and a mildly aggressive 0-60 mph log. 1970 Bronco, 302. Go street 400, w/FCC2. 3 speed manual with 3.50 gears. Stock distributor with a petronix module. Bronco drives well under normal conditions (bogs a little under heavy accel, but I thought that might just be a gearing thing), however when I start from a stop and go WOT it falls flat on its face.

Crank noise fault on you other run? I wonder what is that all about. Otherwise looks pretty good.

when I get towards higher rpms I do see spikes in rpm but not that often.
Why would it fall on its face with a WOT start?

Quote from WillLennon on June 20, 2020, 9:16 pmThanks for the advice. I adjusted it today. My fast accel at the 170F was around a -10. Not sure why I would have made that adjustment. I adjusted it to +20. I also changed my AFR Targets. All of the WOT settings were a lean as they could go. I think I did that to manage fuel consumption. I adjusted all the WOT targets to 13.00 from 13.50. I'm sure I can fine tune a little more, but I just left a good bit of my tire on some clean asphalt, so I am going in the right direction.
