Title: Code out vvt Post by: Vdub-dub on July 29, 2014, 01:00:09 PM Some mixed results when searched how to switch off/code out VVT, so after so here asking again,
After sudden issue with my amk engine hitting over bar of boost and 50+ throttle get heavy misfire etc with no codes and nothing out of place when log via vcds apart from running bit lean that get with misfiring, after swapping out some out plugs,coils and fuel pump think come to conclusion my vvt mechanical has failed ( tests out fine with vcds thou) Being that there little on expensive side to replace somthing I'm insure of wanna map it out tempereally and use one of my old working non-vvt tensionors Title: Re: Code out vvt Post by: ddillenger on July 29, 2014, 01:41:58 PM CDNWS along with ESKONF.

Title: Re: Code out vvt Post by: MadCow on September 10, 2014, 03:26:57 PM Need to set the VVT switch over map aswell, otherwise ECU will see cams as reading wrong. I tried that at one point but it caused all sorts of weird issues, I remember the biggest one was fuel trims not setting and a general lack of power (didn't do any logging to see exactly what was causing it though). I don't think the ECU liked the fact that it was never able to monitor the VVT tensioner operation since diagnosis could only happen if the changeover happens. I don't see how the ECU would see the cams in the wrong position since that's the job of the CMP, otherwise you wouldn't get a cam position code in the first place. @fukenbroken: I have an ATW motor with an AWM ECU, so I never had VVT in the first place. I recently also copied KFZWOP over KFZWOP2 and it seemed to have helped make everything run a bit smoother, but that could be my imagination. |
