ECU R12X vs F12X? Whats the difference?
After researching the ECU part number for my f12x I also decided to research the ECU for the r12x in which I found to be the exact part number. My question is since the part number is the same where does the extra 500rpm come from on the r model? Smaller pill, better flowing exhaust??

there is no real rpm difference.
The ECUs are the same. Earlier F12Xs had different harnesses and ecus were located in a different spot.
If you see a difference, it is due to a problem.

Yea brooke ur ski should be turning 6100+- if running at 12psi of boost via stock ecu. Get a boost gauge on there asap and then u will know.
Usualy 5600-5800 @wot means ur only getting 8-9psi (usual cause for this is bad wgs) or ecu is detuning cause of knock issues

I don't have an R model but if I remember correctly the head is a little bigger and the cam timing is different. I'm sure there are other differences.
