Ok so I'm helping Ryan dial in his MS, and we've run into a weird issue that I can't seem to figure out, or maybe I'm just going full retard.
Here's the breakdown:
Built 1.6 T3 churbo GM coils with NGK irridium plugs gapped to like .25
DIY ms2e built by Ryan and checked on the bench by Mr Braineak himself. AEM uego wideband. FIC ev14 injectors. E85. stock tb. no idle valve. Stock cas and other sensors. Some sort of vtps (will have to clarify with Ryan)
I think that's all that's relevant, feel free to tell me if I'm wrong.
Anyways, here's the issue:
The car stumbles when going into boost abruptly. I'm almost positive its a massive mis-fire. That's what it feels and sounds like.
All the vitals: boost, afr, etc seem to look ok when this happens. When going into boost slowly and part throttle, its fine. Boost cut is raised way up so its not that. Fuel and timing are good and smooth, no issue there at all.
*RYAN: please chime in here with as many details as possible so we can resolve this before Tuesday*
Any help is appreciated. I'm probably missing something or some other type of retardation, but that's what I have you gayz for
*edit: oh and PS - this might not even be a tuning or MS issue, but I want to make sure and rule that out before doing anything else. Ryan is going through all the connections, grounds, and other stuff with a fine-toothed comb now to rule out the possible hardware issue.
