Been trying to figure out a on/off problem with the car. This is a video of what it does as of now. I was originally having this issue along with another, it would go super rich at partial throttle. After examining the ECU, I noticed a burn mark on the nistune board, I am sending that out to be repaired.

In the mean time so I can get to and from work I put my other ecu in. Its just a daughter board tune on a stock ecu. I have no idea who makes it or where its from it came with the car, all I know is its a good ecu.

If anyone has experienced this or have any idea what it could be that would be awesome thanks.

Specs:
SR20det redtop
550cc injectors
gt30
n62 maf
stock intake manifold

Sorry for the small video, but you get the point.
