Hey guys I've got some questions for anyone who knows what they are talking about.

1.) Having the RRM ECU with RRM Downpipe, will the cause the car to run to lean?
2.) Is the RRM ECU a reflash? And will it change the redline/mivec?

Thanks

 

rrm doesnt have an ecu. they have a air/fuel piggyback unit. having the downpipe will not have anything to do with the how rich/lean the car runs, but to answer your quesiton, the 2 together should be fine. the piggyback unit is flashable, but you need the splitsecond software and a standard db9 cable. it will not modify the redline or mivec switchover point in any way.

 

Thanks dude
