How do we install the xkrs flash on our cars? I asked a dealer friend and he said he doesn't think it's possible because each software update and flash is assigned to a specific vin #. Let us in on the secret.

 

He might be a Jag tech or know someone that is a tech.

 

Or you can use a tool CMD Flash. Google it. many cars use this to load the file.

 

Drove it for awhile and let the adaptations set. Re-dyno'd the car and made max 440 hp, 460 tq. gained 40 hp and 60 tq from base run. All from just a reflash. hmm i Wonder how it'd do with an exhaust and pulley upgrade...
