CA18DET "MOT" pollution
Hi.
I just gotten my S13 to the danish version of MOT. And it failed because of pollution. Its a newly renovated engine with new sensors (water, exhaust and everything) and its bone stock besides a 340L AEM fuelpump. Even the catalytic converter is brand new. Ive attached a readout from the MOT. the CO is the issue here, Its not allowed to be over 0.5, and as shown on the picture its on around 1.728. My thought is that the fuelpump gives to much fuel, so the car is running rich. In this case, would a fuel regulator change the outcome?

This is probably me saying something very stupid, but if you get an FPR, you could just adjust the fuel pressure for the duration of MOT. if you have an AFR gauge (you should) you can kinda practice at home before you go. Target like a 16.0 idle AFR.
I realize this sounds dumb as hell, but if it?s to pass a quick inspection, I wouldn?t hesitate doing something short term dumb. I also don’t have to deal w that stuff in PA, USA, so there’s that. |
