Aveo 2.0L - [May 19th] Crappy Cellphone Video Up!

so how is the 1.6L going to run the 1.8L? lol shouldnt it be running the 1.8L so you will have the right fuel maps?

[07_aveo]

It's a 2.0L and I believe another person in the forum who did the swap had to use the 2.0L ECM for it to run properly.

Mapping is least of a problem. A simple piggy back will solve the mapping. How about other sensors? Does the 1.6 ecu direct hook up to this 2.0 engine? Same wiring harness for 1.6 ecu and 2.0 ecu? Or all wiring need to change as well.

wiring harness, and sensors are the same

hmm interesting...proven? or they just look the same?

...yea I have no idea why I said 1.8L...if the harness and sensors are the same then shouldn't the 2.0L ecu work with the aveo?

[ontarian_frog]

Am I wrong about someone having issues with a 1.6l ECU on a 2.0l engine? Was the ECU throwing codes? The connectors might be the same, I'm pretty sure mapping isn't at all the same.

I'm sure your right, different bore, stoke, different RPM timing. howmuch more is it for the 2.0 ecu?, your going to have to trick the car into thinking it still has the 1.6 or trick the motor into thinking it's still in the optra or what ever it used to be in.
Just my 2 cents, I'll shut up now.

Making slow progress, i just got a call from my shop, seems the 1.6L flywheel does not fit the 2.0L, the holes on the 1.6L are smaller and dont line up with the pattern on the 2.0 block so hes gonna call in for a 2.0L flywheel in exchange for the extra manifold i have.

Its hard when you "almost" pionner something hehe so many unexpected things

360 degrees is 360 degrees. even though the bore and stroke are different, the timing would be the same at rpm.. its just the bigger pistons that are moving further. the spark plug timing would be the same, along with the cam shaft position.

the real issue is the fuel curve. some people say to just run bigger injectors or program them to be open longer. but that still does not mean the map will match your needs entirely.. i would think you would need a custom chip, piggy back, standalone or other tune to get the most out of the swap.

but even the stock computer with bigger injectors is a decent starting point.

best way is to get a 2.0L ecu
