Has any one ever swapped ECU's from TSX to TSX. Basically I have a flashed ECU in one car and want to put in in my car. The cars are both same year and transmission. In theory i would have to swap the ECU, Immobilizer, Keys, and Ignition.

Kinda an odd question I know but any help would be great
Thanks

 

Some one did this before.. so it has been done. Its better to find someone close to you that has a TSX and try the swap. I dont know if they swapped the ignition though. Try the swap with a local TSX.

 

If you want to use the keys that matched to the flashed ECU, then you also need to swap out the ignition switch and door lock cylinders. Another option is to swap the transponder chip inside the keyfob without changing any locks.

 

jtso's 2nd suggestion seems more efficient. lol

That's a great idea, I never really thought about those locks. I have all the parts out if the other car and my car is still on the hoist now doing the suspension but I hope to get to this ECU swap this week
