I'm absolutely baffled by this. At 4000 RPM and up, my car starts to stumble. I've got MS2 extra with Jenveys and EDIS. The ECU had been working reliably for nearly a decade. Strangely, if I have the ignition options set to "EDIS" its worse than if I set it to "basic trigger."
Here's everything I've tried:
New coil pack
Plugs
Plug Wires
TPS
Reset crank position sensor gap
Replaced MAP sensor
All with no luck. No matter what, I get stumbles at low loads at 4,000 RPM and up. Any suggestions? I've dying here.
When I look at the composite logger, trigger logger, tooth logger, everything looks great.

Re: Please Help Stumbles High RPM
Sounds like hardware issue.
Year, make, model, engine options, type of plugs, plugs gap... etc?

Re: Please Help Stumbles High RPM
Without an MSQ I am unable to provide any input beyond looking at the EDIS.
I will say that if you have an MS2 you don't need the EDIS.
