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!
