Title: O2 correction not behaving Post by: MmmBoost on July 21, 2011, 02:24:35 PM Just going through a couple of my last logs on my Audi A4 AMB 1.8T and I'm noticing something that does not sit well with me.
When I have hit steady boost I am getting some positive O2 correction which is not out of the ordinary depending on what my EBC is set to.....however my log shows requesting 0.80 lambda......yet the ECU is still adding +10 to 15% and my Actual O2 reading in the log is continuing to go past 0.8 all the way down to 0.73. WTF..... Everything else seems to be in check. Wastegate duty is not being cut and I only have -1.5 to -3 timing correction. Does anyone have any insight into what the cause might be?? Running Maestro 7 software....so the maps I have access to are limited.

Title: Re: O2 correction not behaving Post by: MmmBoost on July 21, 2011, 08:00:05 PM Have about 45 maps at my disposal. Many of them are of no use to me anyway. LOL!
They only map I have for corrections for IATs are timing maps and warmup maps. I think I've got to the root of the problem. I believe it was some adjustments I made to KFMIOP. Apparently even the small adjustments I made were not appreciated by my ECU. |
