Car(04MTRX8) was in shop overnight( repair oil leak from oil pan.) Invoice states "Reprogramed ECM Per bulliten". I called the service department and they tell me the only way they can tell what version I have is by hooking my car back-up (BS I Know). So my question(s) is/are.. How can you check what version of flash you have on your car? And if is infact the "R" what does "R" do for you? I have serched this forum for the answer and also google. Any and all help would be greatly appreciated. Thanks

 

One way to check the "R" flash is to completely warm your car to operating temperature and then hold the rpm's above 8500 for 10 seconds and the car should return to idle on it's own while you are still holding the throttle down. The "R" flash was mainly for the car generating too much heat while stationary. Not sure if it will help you, but my car idles alittle rougher since having going from "P" to "R" with the recall. Have fun.

 

find teh sticky that says "tsb's and recalls" follow the link and then find the 3305g thermal damge recall bulletin. read it. find out if you have had this recall done(call 1800 222 5500 with your vin and ask)

 

Or you can do what Zoom said

The TSB is here: http://www.finishlineperformance.com.../pdf/3305G.pdf
