Ethanol sensor you say? I'm running without a sensor or tune for it.
Eth bypass? Wth is that? A parallel line?
What kind of intakes? Did you $pend the big $ on Black Box?
Can't post the tune or won't
I was curious to see what you were up to in there... Plus I have a weird idle issue and was curious if you did too, or if your tune has a fix. Ethanol is, imo, only partially to blame but basically I adjust Slope for the Eth than at idle it randomly seems to ignore the slope setting and my trims max out and cause a fault. The less slope I add the less of an issue it is, so I have it set to about half what it should be and it stopped faulting out.
Interesting that it started after the mods, but before Eth, yet sometimes works fine. Hmmmm.... What about the tune? Did it happen before or after?
I just looked at the run. Help me understand what happened at 06:01:05 on down to idle?
The pressure drop is drastic, so I wonder if it's cutting fuel rather than running out of it? But I also assumed a fuel cut was at the injectors, not the pump, but maybe it cuts the pump with certain errors and Inj with others? There are some settings in there that I believe prevent cutting the pump. Well, lets say I adjusted them and also don't have issues, if they're related I can't say for certain.
You need to add Injector Pulse Width so we can see wth it's doing. Both to see how much its dumping in, if it's cutting or adding when psi drops.
There may also be one for Fuel Cut, if I recall correctly? I think that one is simply 0 or 1 and apparently it flips to 1 when it cuts fuel.
So right now I'm leaning toward the ECU isn't happy and is causing this, which would be much better than hardware causing it, but hard to say, especially without Inj pulse width data
