1996 Mitsubishi Eclipse gst (16g turbo, ecm link, 750cc injectors, cai, 3 in. Exhaust) So my car has been running rough, has a stumble at idle and lower rpm’s. So I went out and got a used lsu 4.2 and aem Wideband set up. Car ran the same with it in and was around 15:1 at idle. About 5 minutes...

So finally got my cruising AFR up to around 13 and out of no where a day later they just went to 11 and it wants to stay there. My Idle and WOT did not change at all so it has me confused. Any ideas on what could change cruising AFR but not change the WOT and idle?

So still tinkering with my tune to get AFR set perfect. I have seem to get idle to be near perfect it still shows a little rich after pulling up to a stop light around 12.5 then eventually comes back to around 14.However when I let the car idle for 16+ minutes my fuel trims never changed, I...

Looking to see if anyone is local to portland or salem areas I am kind of in between. That has experience with ecuflash, I have adjusted some things and car runs a little better but doesnt seem to matter what else I adjust. To get the car leaner. WOT is ok at 10.5 but idle and cruising is rich...

Just got a sensor installed and my wideband gauge hooked up. At idle the car sits around 13.5 then cruising it's really rich at around 10.3-10.5. When I come up to a light and idle it's around 11.7 idle however once the car sits idle for a while it will go to 13.5. WOT it pegs at 10.0 and I...

Not sure if this is the correct spot for this but....I just installed a freshly built motor into my spyder with the same injectors that came out of the old motor. Car starts and idles great and would seem to be right around 14.5 but when I give it a rev it dips down to below idle speed and...

I've collected a couple sets of logs using EvoScan. I have an innovate LC-2 wideband. Overall it looks like my LC2 readings are 1 - 3 AFR higher than the ECU AFR map through out the RPM/Load range. At Low Load (Load Column 10) my AFR readings were very high in the log (is that normal?) but...

Hello all, I am a new proud owner of a 1990 eclipse gs turbo. I’ve had the car about a month now and have encountered a fair share of problems but with one persisting that I can’t seem to fix. I bought the car with a rebuilt head, and low miles considering it’s age. To cut the BS I’ll get to it...

I just switched to e85 and had a tune done. the car pulls good and cruises very good 99% of the time. there are some issues that have started recently though including... when I go WOT I have a stumble/miss at 6500 basically on the dot everytime. the whole fuel system was just redone and I...
