This is just a theroretical question, but it is possible to convert a GSR to an MR or vice-versa, or are the ECUs completely different. I know there would be a lot of mechanical work with the trans swap, etc., but I'm just curious.

 

AFAIK its just a different ROM.

ie you could flash a GSR ROM on a MR ECU and it would work in a GSR.

 

Thanks. I wonder if we'll ever see a GSR to MR conversion...

 

I have heard of people converting the old VII GT-A's to manual, so I'm sure someone will feel the need to try with this model as well.

 

Actually no .. the ECU is coded with the VIN number .. so if you swap ECU .. you can't start the car ..

The difference between the MR and GSR ROM lies in hex locations 10000 and 30000-60000 .. did a compare between the stock roms and that's what it showed up ..

 

is the VIN stored in the ROM?

 

Looks like it .. but there's another ID for the other ECUs to communicate with the PCM .. this ID can only be coded by mitsubishi .. basically like the immobilizer code .. so you can't just swap ECU and start the car ..

Unless Mitsubishi is blowing smoke up my ****

But I've tested ECU to ECU swap .. can't be started .. maybe .. just maybe

 

I would've thought the same, but...

Anyway, there's still a bit to be learned about how this newer CAN system works. On an earlier beta version of ecuflash, something as simple as clearing DTCs would jam up the communication with the OP2.0 and discussing with Colby, he stated the system still was completely understood. Obviously it's been fixed now but we're still learning

 

Not having done this, I can't provide a definitive answer. But although the ROM can easily be swapped, the VIN number cannot be. It is stored elsewhere on in the ECU, not the same place as the ROM.

At first guess, there may be more work than a simple ROM swap.

 

different rom...
