Hello all,
First time here, and happy to join this community.
I have recently upgraded my R33 GTR ECU to the Link G4+. Got it tuned on the road and am very happy with the results. The car has some mods (bigger injectors, turbos, exhaust, LS2 coils, etc.), and the tuner did a good job of getting it running. However, there are two issues that I am struggling with right now:
1. The idle remains a bit erratic. The revs go up and down a little bit, as do the AFR (air-fuel ratio)...from 13 to 15.5. In addition to this, if I rev the car a little bit (a blip of the throttle), the revs go up as they should, but then come down very slowly. The idle does eventually settle down to 1000 rpm, but I am wondering what the cause of the erratic idle and afrs could be, and how to fix it.
2. The rev limiter is set to 7500 rpm, but the car cuts out sometimes at 6900 or at 7100 rpm max. I am not able to rev to even 7200 rpm. Any ideas as to why this could be? Prior to the Link ECU, I was running Nistune ECU with MAF sensors. Now with the Link, I am using MAP and IAT sensors.
I would appreciate if someone could help me with these issues.
Thanks.
