	Lambda problem 1.8T « 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... Huh

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?

AIT's? Coolant temp? Logs? 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.

I tried using the me7l, but I could not make it work, I keep trying ...

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!
