Ok, here's the run down on how it went:
Before this last fix: Car would run rough, O2's constantly in the 650-950 range (really rich), extremely fouled plugs in an instant, puffing black smoke, 500+ rpm surging at idle, extremely low vacuum (around 4-5 in/hg), fuel trims in TTS Datamaster showing 100% rich (LTerms @ 108 and STerms @ 1).
I fired the car today, and amazingly, it IMMEDIATELY fired up. Goal #1 complete, get car to run. Quickly settled into a decent idle and felt great. then started to degrade. Cut if off and switched to a more recent tune. Fired again and same thing. Opened up datamaster and started logging. Car was showing 100%
RICH (LTerms @ 160, STerms @ 255)!!!
That's new. Car was puffing black smoke still, stumbling badly still, running rough still, surging about 300 RPM this time.
So I sat back and mulled it over for a while, and suddenly like a bolt of lightning it hit me. I've got a mid 230 low 240 duration, mid 500's lift, EXTREMELY tight LSA cam. My money says it's simply.........
Reversion. Makes perfect sense. Car was running like it was pig rich, but was reflecting full lean.
Thoughts?? (Fasterthanyou especially)
