Can't hurt to get a Power Commander - especially if you aren't buying cans from a recognised large brand like Remus or Akropovic, who you know will have at least dyno'd the cans.
I find the 'intelligent' ECU on my '10my SMT to be a pain, constantly hunting around 4-5k revs. I've ordered GPR cans and I'll be bypassing the O² sensors and setting up a Power Commander on a rolling road in the next few weeks - hopefully I'll be able to report a huge improvement.
Thanks mattylad.Hi Shep i would go with the map, the 990s are always lean to get through emmisions regs, i am pretty sure you will be able to get a KTM dealer to upload the akra map fairly cheaply, made loads of difference to mine
Yes I heard the same about the AKRA map being a race tune, hence the question. I'm looking for a smoother ride and not to decrease my mpg as i'm quite happy with the return i'm getting. I'm thinking try the bike with the cans, then get a re-map and see what the difference is in performance and mpg, then decide whether to swap map back. Or get a map switch and flick between the two (have seen a thread on here somewhere about that)Your KTM dealer should have a diagnostic tool which will allow them to alter the fuel allowed by the ECU in the exhausts - so you could leave the CO² sensors in place. I had them do that as a stopgap until I get on a rolling road and it's working so far.
£25 bypasses the sensors completely - there are plugs available off Ebay.
I've heard quite a few people say the Akra tune is a race tune (necessitating you run the exhaust sans baffles) and the bike runs really rich ALL of the time, affecting mpg quite badly. So no good for me - I like an exhaust which sounds good, but can't afford to alienate the neighbours at 7am!
Wise words my friend I think I'm going down that route.I have fitted Leos and removed the small air intake snorkel and the dealership did my bike no probs and yes a huge difference with stronger feel and smoother throttle.
I would leave your o2 sensors and do the AKRA map without hesitation, I may look at a PCV and auotune later.
