HP ECU, is it worth the money?

The HP ECU does the exact same thing on the 2010 that it would do to an 11/12/13. It's a new ECU, so all of the bikes will behave the same way.


With the HP ECU, ABS in SPORT, RACE, and SLICK mode all match the ABS settings from the factory configured SLICK mode. RAIN mode ABS settings match the RACE mode of the original config. According to Alpha Racing, DTC "varies in all 4 modes and is adapted to the use of slick tires on race tracks" which means that it offers progressively more aggressive throttle input at greater lean angles and is more subtle and transparent in its implementation when using race rubber.


No, it's not worth the price by itself, but it was meant to be sold with the calibration kit and more expressly with their exhaust. It would be comical to use the HP ECU with the factory shortie exhaust.


Either way, the HP ECU would still help with the "basic problem of the crude DTC" because as-is with the standard HP ECU map it's optimized to BMW's best effort using their "race data set", so even with the factory map in the HP ECU, the DTC/ABS is improved over a stock 2010/11 and even improved over a 12/13/HP4 if your definition of improvement means being more transparent, but at what point on the track would it be better to just cut them off anyway? Beyond that though, with the calibration software the ECU is completely user customizable and that's really the whole point of it.


Frankly, it would really not be worth the money if you are not interested in more ponies, but especially torque as thats where the majority of the changes lie. If you really want the better DTC/ABS then you are better off just buying a 12/13. If you really are interested in better calibrated electronic aids for track use, then the HP ECU is perfect because again it's user customizable w/ the calibration kit.




They have been that kind. They made the HP4. Your wish has already been granted, you just have to pay for the whole bike. You can get improved throttle response a couple of different ways, A. Get a PCV, B. Get the street legal full Akropovic with the updated ECU codes, or C. Buy a 12/13/HP4.


Almost, but not quite, especially with the 10/11s. It's geared a little high for the streets, so a sprocket change is welcome, and the throttle respose is jerky in RACE and especially SLICK so a PCV is needed to smooth this out as best it can. Not to mention the "crude" DTC is very rude with the power while trying to do wheelies with the electronics on, of course while traveling on "closed public roads."


Then the the HP ECU would be too much wasted potential and money for a bike with street duty as its primary mission. Especially if you don't want to purchase the calibration kit, and especially considering the caveats with the HP ECU, such as loss of RAIN/SPORT modes, and loss of your warranty....for what you want, you may be better off buying an HP4-you get the best of the HP ECU while maintaining the street settings of the 12/13 ECU.


EDIT *apparently, BMW has reversed course with initial guidance and allowed functioning lamps with the RACE ECU*

Thank you for the answers. I already have the PCV and a full Leo Vince system. I got drawn into a conversation about getting the HP ECU as they said I needed it for the track! TBH the bike is more capable than I am, so I'm probably going to leave it as it is. I will probably spend the time and money on suspension (That's where it's always served me best in the past!).
