No, they use the same computer. But the prom chips in the computer are different. It will run fine on the 4.3 chip but it will run better with the V8 chip. After you switch it, I would order a performance V8 chip for it.

I have a 2006 Chrysler 300M I took the original V6 out and switched it with a V8 also change the computers and had a key made for the mission the head of programs but it still won't start

If the computers you fitted are from a donor vehicle they probably have the coding from that vehicle and will either need recoding to match that of the car they are now fitted into or will need decoding so they will work regardless of the immobiliser code.

I suggest you spend a few hours with the car and the wiring diagram and if every part of the new installation double checks ok it will be time to contact a specialist for more info.

I have 99 vt wagon 3.8 v6 was given motor supposedly the same its a3.6alloytec what modifications would auto transmission that come withlall bolt up the same and will the computer recognise all

If this is a GM/Holden product then the engine will not work, the 3.8 and 3.6 are as different as night and day, all the wiring and the computer would have to be swapped out to affect the change, it will most likely bolt in though.

I can't give you direct knowledge, from having personally done this swap before, but I can offer you that the 1990 Cavalier, did have a V6 as an option.
The 3.1 Liter V6 with MultiFuel Injection System.

Of course, you're going to need the ECM, (Computer), and the complete engine wiring harness also.
