Anyone here able to define an unknown rom for me? USDM 2010 RA 55590010. Help would be greatly appreciated. Thanks

 

I also need this. Is there a workaround? I just want to put on gst basemap.

you sure about that number?

 

2010 USDM should use the "55590006 2010 USDM - SST - Ralliart" or "55590007 2010 USDM - SST - Ralliart" ROMs.

Yeah, tell that to my ECU, I have a late 2010. It wasn't delivered until may of 2010. Maybe there's a 2010.5. I flashed the new map fine, and I manually changed my stock rom numbers to match ...0006. That made it readable. Doubt I'll go back...gst map is the shiznit.

 

Are you sure you don't have a 2011 MODEL YEAR car? Often the new cars sold are next years model year cars. For example, often a model year 2011 car can show up at dealerships in summer 2010. On the other hand, dealerships that don't move cars quickly can often have last years model on the lot and still sell it as new (e.g. model year 2009 sold in 2010).

When dealing with tunes and stuff it's all based on the ~model year~ of the car, and NOT when the car was sold. You can always determine the model year of your car by checking the VIN online (http://www.vindecoder.net/car-brand-...rer/mitsubishi ).

Also the goldenevo site does have ROMs for 2011 RAs ... one of them almost matches the ROM ID you listed...

56940010 2011 USDM - SST - Ralliart

Then there's also 2009 RAs...
53600010 2009 USDM - SST - Ralliart

While it may be possible that you got one of the odd ball car's with a weird ROM ID, I'd strongly recommend verifying the vehicle model year to help eliminate any further confusion/potential issues.

 

55590010 is the number. It's a 2010...I don't think carfax would lie about that...I just got it a month ago.
