ECU Compatibility

[Storme93]

My mums AU is having issues with the ac not turning on and i have narrowed it down to a break in the earth wiring or the ecu, me and the boys at work are looking at it being a bad ecu as the car also has a rough idle and weird shifts in the trans ever since the car got wet inside at a car storage place earlier in the year

So it is a series 3 forte and my car is a series 2 forte, just wondering if i can just whip my ecu out and into her car to make sure that it is definately the ecu and not a wiring issue?

Will there be any issues or will it just be a simple straight swap and see job?

Thanks for any help guys really appreciated

Go for it you can only try, they are basically the same.

Series 2-3 ECU are compatible with each other, however you won't be able to just do a quick swap because of smartshield.

To swap ECU's with smartshield you need to visit a Ford dealer to do a pats reset or an auto sparky who can do it, though they seem to rare.

good gold mine - but to answer your question ...... i know with the 6 cylinder versions the series 1 does not swap into the series 2/3, so i'm presuming the V8's are the same as well ..

As above, the answer is no. You will also need the correct catch code for the xr8 ecu. S2 is tuned for the 200kw and S3 is tuned for the 220kw. As i found out, the ecu does matter as mine had a 200kw ecu and was down on power. Once correct 220kw ecu went in, everything was fine including the rough idle.

Good luck finding one though..............
