Nistune Forums

Hey so this is my first time starting my engine since i performed the swap. I decided to go ahead and flash a stock map and monitor stuff. I tried giving it some throttle and i noticed it was acting weird anything about 2000 rpm. I got a caution warning on nistune saying ecu load maxed reached. Here's a screenshot of the max load. One thing to note was that I did not have the stock 02 sensor in, as I'm still waiting for that to come in the mail.

Also wanted to mention that the throttle was registering 1.12 when it was closed and 4.78 when i pressed in the pedal.

No screenshot? Tune and log would be helpful

Here is a log i took, at idle its around 10.3 afr and when i try to rev it, it wouldnt go pass 2500(around there).

Well your MAF voltage is stuck on 0.5V all the way through. Might want to check that out first

Turns out it was a maf issue, the wiring harness that came with my swap was pinned for speed density, moving 2 pins solved my problem, now I just have to find out what’s causing my missing issue at idle.
