Issues with injector scaling
Hey guys, recently switched to e85, along with a ton of other mods...anyway, got fic 1650 high z and they run stupid rich (-25 stft) until I have them scaled around 1250-1270.
This really shouldnt be right, any reason why it would be doing this? It’s on a SD system so i really doubt a boost leak would be the cause

Hey guys, turns out it was a leak...and at the most critical piece...the MAP sensor. After correcting several small leaks (egr gasket, TB gasket, and biss screw) I found, it finally revealed itself. Reseated it and it was fine. Idles fine, and afr is stable...albeit I still feel having to scale the injectors so high isn't quite correct compared to others. However, I'll just take it at this point. Thanks for your inputs.

The reason it sputtered and fell on its face? The car was in open loop for some testing purposes and I forgot to set it back to closed. Therefor it went to read the fuel tables (which I had not adjusted for cruise) and went crazy.

I actually did, at least for what was listed here.
