Erratic a/f issue, boost car, Moto 60s, Walbro, hotwire
Air fuel from tip in to shut down - avg around 11.8:1, but highs and lows of 14:0 registering to 10.5:1 and I mean QUICK jumps
Not really sure what the cause is, just happened to throw some race gas in the car right when it started - pretty sure that has nothing to do with it
Picked up 40 hp playing with the tune on Cam2 purple, not even much more octane or the "right" gas, butl erratic a/f I dont like. Changed WB sensors, car doesnt "sound" off, but still up and down.
may be slipping the belt, boost always climbing but it does jump up 1 psi all the sudden like around 6k. Wouldntt think it would show up with abrupt air fuel changes like that. maybe abrupt rich spots.. but nothing on the tune changed and it developed this
