It's my understanding if you send them an 11 ECM they can send you back an earlier ECM (if they have one available) that will work the exact same. I was told there would be no difference at all in performance or reliability since the ECM's from the 10 model are the same. If you call REV Perf I'm sure they would be happy to talk to you about it. I've talked with them before and they are great to work with.
not to happy with the map from SEPST and the final result of my 5 or 6 vtune session, can,t find a tuner with a good reputation aroud here ...so i will try this new tuner ,i receive my revolution performance EMS from fuelmoto, send my ecu today to RP should be here next week ;-) and maybe next week give you my impression on this new tuner !!!
this is what's inside the box
I have a 2009 ecm, SEPST, cables, software, dvd, and two O2 sensors for sale for $350 shipped.... Play with the racetuner and this ECM or send the ECM for flash and keep your original on the shelf...
