thats exactly what my car is doing. solid cel and breaks up at 4k. the weird thing is i ran my computer in my brothers car with a stock p28 map burned into it with a low rev limit and it worked? so should i check my soldering too?

sorry to butt in on ur thread bossman...

 

if ur getting a solid CEL its most likely the bin or chipping of the ecu, but what i would do is make a new base map, its not hard at all. Also get a wideband to monitor ur a/f
