Title: a4 b6 2.0 alt swapped to 1.8 20v n/a agn enable vvti Post by: PawelP112 on January 26, 2020, 07:54:05 AM hello i have audi a4 b6 2.0 ALT original engine has been changed to 1.8 20v with vvt without turbo (AGN). in 2.0 ALT is a variator, AGN has a vvt chain tensioner.
is it possible to modify the ALT engine software so that vvt works correctly? Currently, the engine works well, the variator plug is not connected, only that it has a small torque of max 150nm I would like to know if you can modify the software from the ALT engine to increase power and torque.

Dont use the ALT ecu use the 1.8t. Otherwise you need to disable the VVT function in the ALT as its compelty different , like you say it has continous adjustment. I dont know why you changed the ALT to 1.8 na as its literally better in every way as its a 2l stroker 1.8 basically.

or how to buy ecu from 1.8t then I will have to modify it for the engine n / a?

Actually it is Alusil, and the cylinders / bores are made from hardened iron and the oil pump is a 06a one and its a better solution than 058 IM shaft. There are ME7 NA ecus out there, grab one and that will work with your ALT dbw. Just disable the VVT since you cant run vvt tensioner in the alt head( which is the most modern and best construction 20v head but yeah), oh also you gonna have to wire the coils in wasted spark config.

can you remove the variator options from ecu ALT and slightly increase the power and torque? / |
