I just installed a chip into my ecu in my 91 teg based off the ng48-PR4tune-19.bin only changed a few things, i boosted my rev limiter up to 7500 cold is 6800 the problem i'm having is when i installed the ecu back into the car it ran rough until it was warm but my rev limiter is down at 3200. oh launch control is set at 3800 donno if that would have anything to do with it but. does anyone know what the problem could be?

so you put a basemap in and expected it to run good?

Dont take this map. It's base on ng48 and its ng61 now. Take the ng61 and copy/paste the data. Mine goes pretty well. Did you hit cut off at full throttle? If yes its a bug from older ng's. They cant extrapolate data because at the last column (full throttle) it take data from the first row (almost idle) to extrapolate. So your engine dont like it! I

If its not your problem, check for lunch control in the proprieties or add a boost map to let the ECU take data to the right.

But seriously dont take this map, its crap and old.

ok i changed the map to ng61 still doing the same thing and my check engine light is on and when i look at my ecu the lights on constenet it doesn't do any flash codes er nothing. it runs like crap doesn't wanna idle until it starts to warm up and when it's warmed up it idles great but still hits the rev limiter at 3200 and backfires alot now. would i be able to change that with the datalogging would it be fixable there or no?

Damn, I think your chipping is not good. Solid cel mean bad ECU so you are fucked. The ECU is going in loop mode so it takes safer setting for your engine. When you floor it dont expect much than fucked up engine! (does this sentense mean something?) Tell me tomorrow of course.
