laser 1.8 awd to talon 2.0 awd ecu swap, will it work?

**See Post #4 for the update, I misread what I was interested in.**

I spent about 30 mins searching for this and could not find any luck. I could not find where the laser/talon/eclipse ecu's are interchangeable with different size engines.....

I have a 91 talon awd, that is in need of a working ecu. I found a working ecu that is out of a 91 laser awd, 5 speed, but the engine is a 1.8.

Will the 1.8 ecu out of the laser work in a 2.0 car?

1.8 dont come awd.
Either the car isnt awd or it doesnt have a 1.8

Besides the laser was not awd till 92. If it was 2.0 turbo you just change two pinouts.

Thanks for the replies!

I re-read everything and it isnt AWD, I dont know where I got it was an AWD unless it was becuase I had multiple windows open at the same time.

So let me ask this the correct way...

Will a 91 5 speed 1.8 FWD laser ECU work in a 91 AWD 5 speed talon?

FYI, the ecu is in Michigan and im in Missouri, so I can't just plug it in and if it works I buy it.

I don't believe so, two different motors.

Nope. You gotta get at least a turbo ecu. AWD or FWD doesnt matter, but has to be a turbo ecu.

Does it matter if the ecu came out of a laser or eclipse as long as it matches the old Tsi ecu?

For example, will a ecu out of a 92 AWD, 5 speed, turbo Laser work in the AWD, 91 5 speed, turbo Tsi?


Lastly to everyone in this thread thank you for all your help so far! It is greatly appreciated!

As long as the ecu is from a turbo laser, talon, or eclipse then it will work in a turbo laser, talon, or eclipse. A non turbo ecu will not work in a turbo car.

I have a similar question. So whether the car was AWD or FWD didn't matter, as long as they were both turbo. I need to swap my 90 GSX AWD 4g63 into a 91 TSi FWD shell. I would be swapping everything engine/drivetrain related, but would the ECU already in the Talon still work? Or would I have to rewire in the ECU off of the GSX?

All turbo ECU's 91-94 are interchangeable with no modding necessary, except that the automatic cars are tuned slightly different because of the different injectors and fuel pressure.

 

[brian9397gsx]

yes the ecu will work but alot of your sensors are different plugs on your motor so you will have to swap sensors and i believe your throttle body

What I'm asking is if I throw a turbo 1990 engine into a turbo 1991 ECU will it work without issues?
