Remap by Hilltop Motorcycles

And I'm still waiting to see a before and after Dyno sheet from an independent dyno because nobody here has convinced me yet that the hilltop graths are anywhere near truthful.
I've thought about it. But it will add another £60 to the total cost. It's £60 extra I can't really afford.
Perhaps if all the doubters and naysayers on here chipped in, it could be done
PS. Mine's a 2005 classic. Not one of those fancy twin cam thingys..

Happy to have mine dyno'd as well if they spring for a second run.....

57 pages on this thread. The numbers of separate people giving good reviews for Hilltop far outweigh those for Power Commander.
I've had a diesel car chipped with a generic map - a generic remap does the same today. It made huge difference in power and mid range torque and was 100% reliable over about 30K miles. Friends have had power modules that change the ECU inputs and long term have suffered reliability problems.
PC has the name for bike tuning, but Hilltop still remains no brainer for me. With no additional boxes wires and connections to go wrong and easily be put back to standard. What's not to like?
A PC will do for those who cannot get to Leicestershire, but a remap with an acknowledged BMW boxer expert has to be the more elegant solution.

Bendy you may well be correct, but ive never seen any wiring problems with a PC, and you retain the unit itself if you decide to sell the bike unlike a remap to the ECU that you dont get back.

Ha ha you must be on commission. What makes Geoff 'an acknowledged BMW boxer expert' ? Of course having forked out £300+ people are going to be positive - no one is suggesting this will have a negative effect.
Btw the PC is also easy to remove and you can get half your money back when you sell the bike.
The issue I have is with the misleading dyno results that are constantly posted on this thread suggesting major power and torque gains to sell this service. They just don't make sense and I agree with a previous post - most people wouldnt bother with this if the graphs showed a 5% gain - but ultimately it's your money...
Not a PC I know but I had a Wunderlich Power Controller fail on me that left me stranded. I also had connector issues with water getting in which left me with a misfire until I diagnosed the problem. If you're adding extra hardware/electronics then you are increasing the complexity which a remap won't do. Everyone makes the choices they want - there isn't a right or a wrong way to do it, just a different one with pro's and con's for each.
Ape.....
Weren't you invited by Geoff (50 million entries ago) to get yours remapped with a guarantee of a refund if you weren't satisfied?
Perhaps you should get some first hand experience and then snipe from a position of strength and knowledge rather than your current position.
Wilsdorf isnt sold on the product but he has tried it.

Yep you are right - but I've always been happy with the throttle response on my twin cam. I would consider a remap or a PC but everything I have read and done myself (I've had Power commanders and a Wunderlich controller on a previous GS) suggests a small gain in power. I don't believe geoffs dyno for one minute and I have no interest in wasting time going over there.
You call it sniping I call it giving an alternative view based on experience and logic. Would BMW release a bike 25% down on power? Emmissions are not measured at peak revs.

Absolutely none whatsoever. ATM bikes are NOT tested for emissions at MOT time.
I believe that whilst we don't test bikes here, they do in Germany and other EU states, and that recent bikes from BMW are to Euro 3? regs built and therefore will have a degree of tune and set up to meet these reg's, it therefore follows that a re map might improve mapping etc and therefore the smoothness etc of the machine, as to horsepower I have no idea
I have no experience of re map on GS so wont pontificate on the subject, but have just had an 2013 Aprilia OEM update on my 2011 1200DD, which has made a big difference in smoothness and mpg (its a stock map so not intended to increase power), on the DD the problem was overfuelling but even so it proves new maps can sometimes improve things whether from OEM or from an 'expert' - you pays your money..............

You can't use a diesel car remap as a comparison! Diesels have a turbo so you up the boost and the fuel you can get a massive gain in power. Same goes for a turbo petrol engine although it's more limited. A normally aspirated engine though has no way to get extra air into the engine via a remap. That takes head work and camshafts along with a lot of time and cash. And there is the rub, without getting more air into an engine, gains will be strictly limited to what you can fine tune and better use of the limited air avaliable to you.
I totally belive hilltop offer a good service in so much as your bike will run far better than stock. Their dyno sheets just don't add up though but hey they aren't the first nor will they be the last tuner to exaggerate.
Don't let that put you off though, as I said they do a good job at smoothing out power delivery and it's cheaper than a PCV plus dyno time to set it up properly.

Partially correct. I would say that at present, modern engines are running with excessive air, therefore - will burn some extra fuel quite easily, and to good effect. Once you reach that level - going beyond to any extent , will as you say - require additional work (although not necessarily - head and camshaft work - air induction and exhaust improvements may suffice).
Don't forget that a remap requires dyno set-up - every bit as much as a PowerCommander.

Yep and that all depends on how poor or good the original setup was. You don't have a snowball in hells chance of getting the gains that some of the figures touted here suggest though.
My mate had major trouble with his PC3 on a 1200GSA when the connector to the throttle position sensor got soaked in heavy rain whilst touring in Scotland, it got so bad it wouldn't restart after buying fuel. Luckily being in the right place to buy WD40 helped, a quick disconnect and spray all connectors and the fault was cured (temporarily). PC3 now removed.
I had same as Pukmeister's friend. The PC connectors are poorly put together versions of waterproof connectors, but they omit the seals. My bike lives outdoors and gets used all seasons, the connectors leaked and resulted in spurious behaviour after about 18 months. I junked it after that and recently went for the more straightforward remap from Hilltop.
We had a misfire on one of our GS's on a recent European trip - in torrential rain. It transpired in the services that it was down to the PC-V, which was quite easily remedied, but we could have been more robust in fitting it in the first place, which would have prevented the issue. Once sorted it has been problem free since. No issue on the standard TC, or the remapped bike in the rain so far

Here is another thing too consider.........accelerator module. I bought one months ago for my GS but didnt get round to fitting it. So i think i will fit it to my new bike. My question to the more knowledgeable bods on here (and there seems to be many lol) Should i fit it now bike only done 170 miles or should i wait a while and see how the bike performs, it seems ok but its not done much. Advise please
As far as I can remember we Dyno'd one bike - fitted the Accelerator module and did the Dyno test again......... no noticeable change. The ACC module is really just a Resistor with a bit of wiring as far as I remember - this changes the value of the info sent to the ECU, which in change will add more fuel to the mixture. however the ECU is the little shite that then talks to the Lamda sensors, which tell it that the ratios aren't correct and the ECU re-adjusts again to compensate....... so really you go into a loop.
We then tried the ACC module and actually disconnected the Lamda's...... and yes then we noticed a difference and the bike was great for a few rides, but not advisable to do this on a long-term basis. In fact we removed the ACC module and tried it just with Lamda's disconnected... and response was same as with the module connected.
If I was you... do a run for a few miles - carefully disconnect your Lamda's and try the run back again... see if you notice a difference in response...?
