Hi all, thinking of fitting either power commander or rapid bike Evo to 2013 twin cam , is it worth it any advice would be appreciated
Power commander or rapid bike Evo
- Thread starter kingo
- Start date
AF-Xieds are the way to go, not tested the rapid bike evo so do not have any data.
Power commander is Ok on a primitive early Japanese injection system but BMW is a bit too advanced for them.

I bought a used power commander for mine to put me on until it was Hilltopped, couldn’t really tell the difference between each, the bike felt very different when I removed it to go for remapping though. I still have it, £100 if you’re interested.
May be interested What one is it 5 or 6
without wishing to speak out of turn, years back a bunch of Italians rocked up for a week at PDQ to prove their magic tool was the way to go - after hours and hours of testing at the end of the week they were told to sling their hook as every day was a new day and their gadget made no sense
my recent testing with an AFR sensor has led me to believe why a power commander is a joke on a BMW (and why they no longer make them for BMWs models after 2022). Normal vehicles these days moved to a MAP sensor and AFR sensing wideband CAT sensors - but BMW even on euro 2026 model year euro 5+ emission standard bikes like the R1300GS's are still using archaic old world tech. They have used a MAP sensor based system on BMW cars for at least 20 years (as do recent Ducati and Honda bikes), it brings a far better understanding of vehicle load, allowing more intricate fuelling along with wideband sensors. But Ricardo who manage BM bike emission testing, like the idea of individual gear engine mapping they already understand, so they can work around various needs.
On my GS the reason I can't ever manage to get my power commander 3 to work as well as I want - is each gear needs a different adjustment layer - this just isn't part of how dynojet do things. Indeed BMW mapping adjusts its fuelling in much finer throttle steps than the budget power commander does - so BMW are trying to re correct what the power commander layer is doing all the time - so you just have a muddle up of rubbish
I'm led to believe Hilltop have never mapped anything - they just get at the bikes std adaption layer and force things to the extremes of what the BM ECU can manage on its own...
I can't verify they have things right - but woolich racing who have been riding around every other remapped bike on the race track for the last 10 years (well before they owned a dyno) - have moved heavily into offering a real way to get at the BMW mapping in the last 3 years - and are who larry now says are further up the road than all the others

5, i think
Thanks for reply ,have decided to get rapid bike Evo
big mistake
the AF-Xieds would be far more sensible - https://www.beemerboneyard.com/bmwafo2sema.html

you should harass woolich - they don't do a map for the old GS's yet, but that's
1) coz never ridden one to realise how desperately it needs it
2) have no idea how much money they'll make when they do
they didn't do BMs till I explained how much money they are throwing away - now they get the madness ricardo put in there, it will take seconds for them to come up with a better start point
I was just reading about a guy that threw his brentune in a skip and is still getting his head around how much better the woolich map is for his k1600 - they didn't have that model till recently - when I told guys on a US K1600 forum about the one company that knows what they are doing needs a nudge - and now its out there - supply and demand and all that....

I second AF Xieds. Hard to get hold of as believe Beemer Boneyard won't send them to the UK owing to the need to register for UK Vat. Do you know anyone in the States that could get them and then send them on to you?
