hp4 ecu flash

Hi people's has anyone had an ecu flashed on there hp4 , is so what were the gain's , cost , and were did you have it done cheers

i bought a my genius gadget from Bren tuning in USA you can re map your bike etc was supposed to be the dogs nuts, But it wasn't, so i stopped using it, I got power commander with custom map (set up on dyno) and its loads better

So to say that your bike was better in tune with the Power Commander of the Flash BrentTuning ...

Cheers Kevin, that's useful info. The Bren is supposedly good, what was up with it?

My BrenTune was brilliant on my '12,but only after I had it custom mapped on the dyno via email.(pickedup 4bhp peak and 8bhp midrange over mapped pcv,with the option for another 3-4bhp topend on race pump fuel).

I know they had excellent results with the 2010/2014 s1000rr,not sure about hp4 or 2015's.

Bren tune wasn't good for me at all sometimes my bike wouldn't even start i had to turn it off and wait a minute then it would go again i was in contact with them a few times but got no joy, i had it on dyno with Bren tune on and the curve was crap, But when you think about it the power commander with custom map is made for that bike and we all know every bike is different, as for s1000rr and hp4 the engines are the same,

I find it strange that some speak wonders of Bren Tuning others do not, my opinion is not worth the money they ask to do the reprogramming think a lot of money I've ever had to send my ecu for them but was too expensive for the horses that would I think win with a Power Commander V with AutoTune or with Bazzaz Z-Afam will have the same results or similar with a lot less Money.

The systems either work or don't work - if they work on one S1000RR then they work on all. The difference is ALWAYS the mapper/installation...ie it's always a human issue or the exposure of an underlying issue with the bike that pre-existed.

(NB: Obvious caveat of a faulty piece of hardware, but then that should be a warranty issue not a power curve one)

What is up for discussion is the amount of possible gain from the use of such a system. I'd argue that potentially HP4's have less to gain, they come from the factory with less restrictive exhausts and I would assume they are mapped slightly more aggressively, as being a limited edition they can worry less about emissions targets and more about the ultimate drive-ability/power. It depends on your ultimate goals.

There are at least 3 other options.
ECU Retune from Hilltop or other.
BMW HP ECU
Rapid Bike
+
Bazzaz
Power Commander
Brentune

Just to add I would always want timing and all injectors adjusted by a piggyback, signal-fudger as a minimum.

ECU flashing gives the facility to alter other parameters within the ecu,for example,ignition advance,dtc levels,lower gear power reductions etc.
Without a dyno tune a flash will not necessarily produce more power,and possibly less(same principal as a pcv with dynojet map-improvements can usually be made by proper dyno set-up).

The problem with a flash is you only get what the programmer thinks is best!,and even then,do you really know what they have actually done?

With regards to the Bren set-up,I think the biggest problem was that primitive mygenius download tool! (they now use much more up-to date methods - mind you,that's another issue as I paid for the tool,which is now redundant!).

Obviously,the best option is the hp race calibration kit and dyno set-up,IF you can find someone clever enough to give you exactly what you want.

Personally,I was quite happy with my hp4 with decat pipe/mapped pcv.(Genuine de-cat pipe now for sale,as it happens!).

HP Race Calibration Ecu is a good choice worst is aranjar someone who works well with it and the price tb is very demanding, the guys who have the HP Ecu and chose to put the PCV to work with HP Ecu because HP Ecu refines petrol 1000-1000 rpm and PCV tunes gasoline 250-250 rpm is more accurate in pitch can take better advantage.

Still think my hp4 with power commander and custom map set up on dyno is much better than a bren tune tool. you could tell by the graphs on dyno chart and when riding the bike, Bren tune are expensive and would not do it again, i,ve also heard that hill top motors are good with ecu re maping, But to be honest its hard to find someone who is good at there job at tuning, some tuners are good at talking that they are good, SO the question is who is good at there job ? Anyone know ? as i would like mine to have full potential

Kevin because not trying to make a refresh on Alpha Racing in Germany going home mom soon will they know what to do in your ECU to the modifications you have on the bike.

This. I know good car tuners. Track Electronics in Norwich is where I would go...bit far for you.

eh ! i can not make sense or your question ? what do you mean ?

Had my last s1000rr and my hp4 set up from dynobike in malton north yorkshire good bloke, But just wondering if any genius tuners out there who know how to get the best from a bmw, midrange is where you want it

Tuners are few and far between in Scotland so there is not much to choose from but I do beleive if you want the best out of your bike then when it comes to getting dyno work done you go to either someone that comes highly recommended as an independent dyno tuner or someone that is a specialist on that bike, I look at the Superstock and Supersport team from BSB and see which teams are doing their own tuning or who they are using and generally go from there.

Down South I always used to use Dynospeed developments in Essex, Dynotech in Bramley Hampshire and Phil Seton in Colchester, HM Racing in Kent.

Pretty much every one of them were well known for doing dyno work on race engines at club level and above and all of the tuners have race bikes too so they tend to know what they are looking from the seat of the pants dyno too

As far as flashing an ECU goes it is never going to give you a map that will perform 100% particularly one that is loaded when the bike is static, only dyno tuning can do that because every single engine is different, at consumer level everything suggests that the Bazzaz unit seems to be the better option for the BMW specifically because it allows control over all 8 injectors rather than just 4, I have always used power commanders for my other bikes but that was because they did what they needed to do, on the BMW a PCV to get the best out of the bike would need to have an additional module to take advantage of the extra 4 injectors which then means double the price of the kit pretty much. Although the autotune module on the PCV would work wonders.

Your right in saying that every bike is different you can not just send ecu away to get flashed as a custom map is made for one bike only, i remember years ago me and a pal had gsxr 1000 k3 and went to holeshot racing (jack frost) and both had to be done separately he wouldn't use same map on both, (he is a great tuner but unfortunately he moved to Ireland) will leave my hp4 as it is with power commander and custom map by dynobike

I agree with Mick 753 each engine is an engine and each have their tuning or going to a dyno and you make a custom map for your motor or else you buy a PCV with autotune or Bazzaz with z-AFAM doing the same service custom map for your engine.

Hello Kevin

I also had brentuning first V1 tune with the mygenius device. I end up losing power and my bike got slower after 9 and 10rpm. For some reason my friend on the track would be able to pass on long strait always with no problem! Bren tried to fix my problem with a remote custom tune and I still had the same problem! I did multiples test when being on the track going from stock map to bren map with his mygenius device to make sure I did have an issue. On stock map my bike would feel slower under 9rpm compare to bren. I have to say bren map in lower rpm felt faster but back on stock map most of friend had to chance a long strait away! Bren decided to drop me customer support and told me I don't understand his tune. One good way to show your clients you have a good product! Months later V2 come out from BT and I decided to give them a call and purchase V2 to see if this update would fix my issues. To my surprise they refused to sell it to me saying I'm someone who those understand how tuning works. I have 15 years of riding experience and during this time i owned 10 bike that I all modded and go them tuned by professional tuners. I do maintenance and install all my aftermarket parts myself! I know about tuning my bikes or when I have and issue!

Stuck with bren tuning V1 and end up finding OE Tuning true a friend that deals with them on car tuning. To my surprise i leard that OE Tuning and Brentuning started developing The first S1000RR flash tune together. For some reason they had a falling out. With OE Tuning i got great results and my bike runs better then ever! I'm not trying to say OE is better then BT as many people got great results with BT just that Bren should of help me out more with my issue.

Kevin did bren try any else to try and fix your issues?

PS OE Tuning let me keep my mygenius device I purchase from brentuning, they are able to provide you a unlock code you enter in your device and that will let you load OE flash maps. Also OE offers the android flash device that suppose to be easier to use.
