Part #802-03803 R&D R3 ECU; Reprogrammed ECU for the FX HO offers offshore race inspired and race tested ignition timing map advancements that produce quicker acceleration and great top speed performance. The fuel maps are tuned to offer a cleaner than stock idle (leaner idle), clean and green cruise areas which will keep fuel consumption either the same or better than stock in the cruising ranges, improved hard acceleration enrichment for the hard core rider that wants a more aggressive mid range acceleration, and an overall improvement to top speed or wide open throttle ranges. The rev limiter is raised to allow up to 8350 RPM that will promote a more positive pump hook up in rough water conditions. The R3 ECU Program has been used to win the N.A. Class Overall in the MH300 Offshore Race two years in a row, as well as Iron Man Class 1st Overall in 2011. The R3 ECU programs are 91 octane (pump fuel) safe. The R3 ECU program can be used with R&D Performer, Stage 1 and 2 kits. The R3 program file does not require a PowerShot Fuel Tuner. Used to win the N.A. Runabout class in the 2012 Mark Hahn 300 Endurance Race.NOTE: Custom Rev Limiter settings available upon request.
