Title: Med 9.1 Ingnition retard /knock Post by: kepsus on May 21, 2021, 10:45:56 AM Hi first thanks for let me joining here.
I have a problem that my car report knock. Original it was a BWA, but got a build CDL engine in it and fitted dsg. I have the vcds log here both where you see the retardm and knock, and with the knock sensor volt. https://easyupload.io/m/5zb38n (https://easyupload.io/m/5zb38n) Does it looks like "normal" knock, what i find strange that i have tryed also to put my aem meth with (75 % meth) on max, and seems like it dont affect the knock sensor at all. still same Title: Re: Med 9.1 Ingnition retard /knock Post by: Bitshifter on May 21, 2021, 08:31:12 PM WTF :o ~10°retard @ 4800rpm on Cylinder 2
That`s not normal! Do you can log real (EGT)-temperaure? What is with AFR? BTW: better made 3/20/115 Log, next time! Title: Re: Med 9.1 Ingnition retard /knock Post by: kepsus on May 21, 2021, 11:59:56 PM Here is a fresh one , https://easyupload.io/jo61nx (https://easyupload.io/jo61nx)
Title: Re: Med 9.1 Ingnition retard /knock Post by: Bitshifter on May 22, 2021, 11:45:06 PM Pretty easy: boost pressure difference to high, maybe because of bad tune => check PID an an tune it.
Title: Re: Med 9.1 Ingnition retard /knock Post by: kepsus on May 23, 2021, 03:52:11 AM yeah i see some high spike, but would that explain the knock, even with the spike i think it puul a lot of the ingnition.
Title: Re: Med 9.1 Ingnition retard /knock Post by: Bitshifter on May 23, 2021, 11:44:50 AM 14% boost spike...respect! :o
So read my first post again and try to answer. Title: Re: Med 9.1 Ingnition retard /knock Post by: nyet on May 23, 2021, 01:04:26 PM Fix your pid

Title: Re: Med 9.1 Ingnition retard /knock Post by: Bitshifter on May 23, 2021, 08:34:04 PM Is the MAF totally wrong or is there big turbo installed? I think it is not only wrong MAF or big turbo. We don`t know AFR, EGT, or basic details of sw. Title: Re: Med 9.1 Ingnition retard /knock Post by: kepsus on May 23, 2021, 10:42:07 PM Is the MAF totally wrong or is there big turbo installed? It is running TTE480, upgrade hpfp, and Lpfp, injectors from AKS, which should been around 15 % more flow than rs3. 165 bar fuel return valve. 4 Bar mapsensor, 200 bar fuelsensor , and upgrade chargecooler.

I think tte use stock manifold?

It is standard manifold, Think they have ported it, if i remember correct Title: Re: Med 9.1 Ingnition retard /knock Post by: Bitshifter on May 28, 2021, 06:36:29 PM https://tteglobal.com/audi/a1/2.0tfsi-2012-quattro/17/tte480-tfsi-upgrade-turbocharger It is standard manifold, Think they have ported it, if i remember correct cound`t believe that ("stock injectors, stock lpfp")....never ever! OR WHP means "wish horse power" ;D ;D ;D |
