Launch control is not enabled in program, so barring some odd issue there, I think we can rule that out. The VSS error at higher speeds is a possibility, I have no idea the age of the sensor. I'll hook up the Oscope this weekend and watch the data input to the ecu, see if it's dropping out on me. If it's not that Ill grab a log and post it up. I wonder if you could be a little more specific with RPM reading incorrectly? Is that going to be sensor or wiring that you have in mind? The dizzy is less than a year old, brand new (not reman), so if that's the case, warranty here I come. But I would think that that should present regardless of gear?
A little more specific on the issue, actually. When the limiter does engage (again only in 4th gear) the cut lights turn on in neptune, and I holding the throttle WOT, I see the RPM drop to around 3k, up to 4500, back to 3k....The AEM UEFI shows --- (far lean, no fuel)
I will also check free rev this weekend to see if it does it at a standstill. It could very well be some weird launch control thing, maybe I have to turn it on then back off for the program to set it? Not exactly sure.
