Title: Lambda problem 1.8T Post by: Twin on December 08, 2015, 03:40:54 PM I have a VW Golf 1.8T engine code ARZ With some mods:
conical air filter AEM Dv APR R1 Audi RS4 spark plugs (NGK PFR7Q) Coils audi r8 Forge Intercooler Downpipe 3 " I started changing only the maps LDRXN LDRXNZK KFLBTS, the car was good but when you have full boost lambdas are rich 0.70 or less (I have a wideband aem where I see the AFR), if you do not get full boost or go slowly lambdas are OK KFFDLBTS put to 0 (temporarily) but keeps going like no improvement... ??? I only changed LDRXN LDRXNZK KFLBTS KFFDLBTS the rest is stock The lambda values of the channel 32 with the engine at idle are -1.5% in the first cell and 0.8% in the second. I need help to know why the car gets these lambdas so rich and if I have to change any file or change something. What do i need to log? Thanks!

Sorry I put some logs before putting KFFDLBTS to 0, as is the lambda obtained is very rich, you need a log of any particular channel?

Hi KFFDLBTS put to 0 to see if it improved but continues to enrich Now I have so KFLBTS: as you can see the defendant richest lambda is 0.80, but ignores the ecu and enriches more later i'm gonna log by using me7L, what variables do i nedd to log?

There was a thread about this a month ago; the guy disabled everything to enable fueling to force 14.7 but it still enriched. Worth a search.

While trying to learn how to use the ME7L, I have a few logs with vagcom, during the logs, the AFR has oscillated between 10.3 - 10.7 vagcom not show failures, any ideas? Any help is welcome! Thanks!
