Yesss! It runs!

Thanks Brain and Reverant for helping out with this one, I really appriciate the guidance in tracking this down.

Did a little bit o' AutoTune around town tonight and watched how the MS pulled all the fuel out of the 90 & 100kpa rows now that I'm NA... lol. I don't really care though because she's running

Quick AutoTuning question: When I partially lift the throttle to slow down, it looks like the MS is still injecting fuel as if I was under load and it gets super rich, and then it tries to pull fuel, only to add it again once I get under way. I would imagine I'm wasting a lot of fuel seeing as how it does this every time I decelerate. Is there a way to "tune that out" or "turn it off" or is this just something that the Megasquirt does?

Also, about that C11...

I dunno, the trace was lifted/not connected and causing the issue with the MAP singal. When I tried to repair (see burn marks), I failed and just put that extra cap that you see on the board in place.


for lifting: see overrun.

Check your "Over Run Fuel Cut" settings. You might need to play with the values there until you're happy with the result.

Yeah, the burn marks are what clued me in on that. SMCs are a bitch. I'm assuming the "extra cap" you added is the one that looks soooper jank sticking out of the board that I can't find a reference to on the microsquirt diagram? Also, get yourself a flux pen man! Gesso reflowd probably about 6-8 of the pins on the microsquirt header that looked about as dubious as 21. ಠ_ಠ

Awesome, I shall look. I'm guessing this is somewhere in the autoune settings? All I know is that when I lift with the stock ECU, it goes full lean. With the MS, she's still dumping fuel. Someday I'm going to need that cat again to pass smog! Thanks guys!
