'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.

most of us freedom loving christian americans don't know a thing about that 1.6...but its probably a safe bet to just swap everything over sensor wise.

hustler, please dont even joke.

I'm not totally sure but I think I read something somewhere about the ecu controlling the alternator that wasn't compatible. I'll check after the job tonight

leave the fucking sensors
bolt everything in

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.

This is exactly what I am thinking. I assume that timing in 1.6 stock ecu is completely different but we can handle this with emb.
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

yes, in closed loop it will try to reach stoich. I don't think the timing map is all to different between the two, but if you have the means to dial it in with your emb you absolutely should.
