Upgraded Fuel Injectors

[TheArtJunkie]

Whats a compatible upgraded fuel injector for the 2011 aver anyone know?

most fuel injectors are interchangeable as long as you match them up by size, and impedance. then you pick your flow to match your set up.

that means you need some where of programming the pulse width or the fuel flow table inside the ECU

He didn't ask about that though.

I would look at it two ways, if change one thing, you need to reprogram it to work with everything else.
Or in the case of the 1.8 in the cruze, which supposedly uses exactly the same ECU maps as the 1.6 ecotec aveo.
I would think since there is bigger displacement, there would be "bigger" injectors, and a maf matched to that.
It all should run on our stock ecu.

Most of the maps and ecu can bend and adjust to run with slight changes. I don't think you could fool the computer.
A bigger injector would just make the ECU cut fuel to maintain the o2 sensor to the maf sensor values. If the ECU needs to cut more fuel than the programming allows then you get a check engine light. But if everything you put in matches like the 1.8 everything. You should be able to run without problems.

This is why ECU reprogramming is also great, because you can often achieve the "same" results without changing parts. Like more fuel without buying injectors, just change the pulse width.. Only time you need bigger injectors is when you turbo, or something else, which would require new management anyhow.

Of course, nobody can match the Rabbit's wisdom both in answering questions or the technical support.
