Yes, I had EDR flash my ECU. He uses custom in house ETV maps, fuel and ignition maps etc.
Its practically unrideable without a flash IMHO. I don't know how some people do it.
I have not installed bar end mirrors. With the signal integrated into the mirrors, fabbing up front signals appears to be more effort that I want to put into it.
That said, I have a set of CRGs that would mount up nicely.
Here is what I have done to mine so far (I just hit 530 miles)
ECU Flash
FiTech Autotune
Graves cat delete low mount half system
-1 front sprocket
Cox radiator guards
Sato Rearsets
ABS dongle
Vesrah XX brake pads
Superbike Grips
Light Smoke ZeroG Corsa windscreen
Graves Tail Tidy
GB Racing case covers
Shogun Frame sliders
Rear spools
PAIR valve delete
Ram Air flapper delete
EXUP valve and servo delete
Ohlins manual Steering damper
As a side note, the brakes feel much better with ABS disabled. Kinda vague with ABS on.
I ride mostly in KTRC Mode 3, ABS off, Full Power, KEBC on Low, and QS up/down active. It wheelies just a little when I want it to, but not like the BMW which is wheelie on command.
SuperCorsas will be replaced with Dunlop Q3+s soon, and Q4s for the track.
Will also be going up to a 41 tooth rear sprocket this week.
