'99 1.8 engine into a '01 1.6 fl
I was searching the forum and couldnt find an answer.
Is it possible for the 1.6 '01 ecu to handle the '99 1.8 engine without modifications and running smoothly?
From a quick search I've found that 1.6 from '99 to '05 and 1.8 '99 engines share many sensors.

if you think about it like this it might help. the ecu has absolutely no clue what hardware is in your engine bay. like your engine. so if you put all of the sensors from your 1.6 on the 1.8, it's not realy going to know any different. just do that and put the 1.8 injectors in. might not be a perfect tune, but it should be as good as any other factory tune. essentialy you'd just be swapping hard parts not electronics.

Also in closed loop wont the ecu try to reach stoichiometric values?
At open loop we can re-tune the maf signal to achieve the desired afrs.
What do you think?
Thanks for your answers
