I already said no codes. The car definitely feel more responsive and the sound is about the same to me..

will the reflash be done via mailing in your cpu to RR?
do you think gutring the cats and rhe o2 mod will and or the flash be detected by the service dept. And put ypur warranty at risk?

Anyone know how and where to remove the ecu so I can send it to rr-racing?
They were supposed to email me a pdf on the instructions weeks ago but I haven't heard anything from them..

Well I got my first code yesterday but cleared it out with the app torque. I'm sending my ecu off today to rr-racing for a tune so that should take care of that.

My ecu came back in yesterday and back in the car. I want to give an honest review so here goes. I have only driven the car 2 times since and maybe the ecu needs time to relearn but I cannot tell any difference at all after the reflash. RR-Racing was very prompt and gave great communication throughout the process. I knew ahead of time that this reflash wouldn't be a huge gain but for $400 I was expecting more. Maybe the ecu needs more time to relearn but I was not told of anything..

Please keep us updated if the RR racing tune permanently rids of the cel that comes on for you once in awhile. Thanks

Maybe unplug and replug in the butt dyno? It only has two megabutts of memory, could be full of backed up data.....

I'm guessing now that's why no one else has really given any feedback on the reflash for the rc-f..

The ecu has to relearn so you have to do some high load pulls in higher gears. You should be able to feel it get faster and faster.

Just wanted to follow up after getting a few more miles after the re-flash/tune. The car does seem to actually feel better and better the more I drive it... No codes...!!!
