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.

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

its normal for the factory ecu to wait a few seconds at idle, then richen up the mixture and turn off closed loop.

I noticed this myself years ago when fooling around with the wideband -> narrowband simulation.

Hmmm, I've never experienced that issue before until I ran into all of these issues lately. It never did it on the nistune I had in the car.

Well I guess if that is the case my original issue is my nistune board.

video: stock redtop, stock ecu

any stand-alone would "fix" the "issue". But it makes you wonder... why put it there to begin with?
Maybe Nissan has a damn good reason for it, and we our ruining our engines by keeping them at a steady 15~ air fuel while at idle all the time.
