Rexxer ECU Tune - Options

britm3 · Dec 18, 2014

OK guys now that my throttle APS sensor is replaced under warranty, still looking to perfect the fueling on my '13 hyperstrada. Looking at Rexxer ECU tune options - and wanted to get some opinions on what matters, not really looking for power - just smoothness. You can spec:

Exhaust: Slipon, Full or OEM
MidPipe: OEM or not
Muffler Baffle: Yes or No

Disable 02 Sensor: Yes or No, assuming this allows full cycle mapping.

Disable Exhaust Valve: Yes or No

Pump Fuel: 93 octane or not.

Has anyone gone through the process and disbaled the O2 sensors and exhaust valve - just looking for impressions.

V twin - keep the revs up - smooths out nicely.

Hello britm3,

I did my 2013 Hyperstrada using Rexxer map. My tuner using the QD mapping and disable my exv valve. My stock exhaust have been modified by removing the built-in cat.

The result? No more sudden engine stall in sport mode and throttle response is very good!

My shop said more air, pipe, 14T front sprocket and Rexxer map is a common Motard tune, though he didn't specifically say 821. I asked him how bad it reacts to just the MWR HE filter kit and he said not that bad, as in, won't be screaming for a re-map.

Just not ready for a pipe so I'll either wait for a Rexxer map or just buy one of the programmers so I can update anytime.
