View Full Version : Rexxer tune

04-24-2014, 03:34 PM
Finally got out for a ride with the Rexxer tune. All I can say is I'm not very happy with it. Good power but rideability is crap. Super abrupt part throttle with crazy engine breaking.
Disappointed to say the least.

I faced the same issue with the new Aprilia mapping. Did they do a dyno run? What exhaust are you using?

Sorry, Just saw you have a Leo like me. Have you tried the Arrow mapping before you changed to the Rexxer?

Ya I've had every map out there on it. The moray recent stock map works well but lean and the Arrow map works better but crazy rich. I may go back to the Arrow map and see if I can move the O2 sensor further up the pipe.

However upon further investigation there isn't anywhere else to put the O2 sensor :/ Stock map with Fat Duc maybe....

FatDuc with stock map works good for me

That's what I'm thinking I will probably do. Sucks balls that a $300 map doesn't work better.
