Noob struggles SURPRISE!
1991 Miata 1.6
Td04 16t Megasquirt plug and play Afm delete GM IAT MTUNED COOLANT REROUTE FM Radiator Aem uego wideband Flow force injectors 620 Dw300 fuel pump DIYAUTOTUNE ebc not hooked up until I get the tune dialed in FM intercooler Gated at 6psi So I set up my injectors per ff injectors recommended settings. I set timing to 10 running fixed timing. I set up my uego and it's reading identical to gauge. My question why do I keep getting erratic idle speeds and afrs without even changing any settings. With the car up to temp it still fluctuates. I thought maybe my manifold gasket leak so I sprayed a little started fluid around each runner and I didn't get fluctuations. The only thing I can do to make it manageable is ten and ground jumper. Also it took a ton more fuel to control some rediculous lean spikes in idle throttle increase. A lot a lot . I got the majority of my afr to be below 14 and I can get it to idle around 14.7 with fluctuations even with the jumper. Does this make any sense to anyone. Tomorrow I'm gonna try to post up some data logs and screen shots. My ve tables are wacked now so I could get it to kinda idle right and get my afrs in check I bought the upgraded tuner studio a while ago and the never sent me the registration number so I can't autotune dick lol. |
Screenshot of your deadtime settings? Originally the GT500 injector deadtimes were measured incorrectly.

1.12ms @ 13.2v with a 0.144ms/v battery voltage correction

Should be fine. What is your idle valve set to?
grounding ten wont do anything with the megasquirt. So if thats changing something then its just placebo. |
