1.8T no fuel trims
« on: August 03, 2022, 03:11:58 AM »
Hiya
Swapped my daily car (1.8T AUQ K03s) to a complete TT225 K04-023 setup.
I'm running 1ML906032A as a base map with some changes for no EGT, 2nd o2 delete, 4 bar FPR and BFV ldrxn. (And 17705 patch but needs some more investigation).
Needs some fine tuning but the problem I'm facing now is fuel trims not working at all. I probably ffed up a codeword but can't seem to find the issue. Car doesn't throw any DTC's after necessary deletes. TIA.

It also doesn't work on stock sw (probably due to 2nd o2 or EGT?)
I'll do some more testing

Fuel trims now work with EGT, 2nd o2 & N249 delete. And my other mods.
