Remap by Hilltop Motorcycles

[Sot1200]

Has anybody had their bike on a before and after dyno session on a dyno not connected to the person doing the work? ........................... I still find it very hard to believe those figures are correct.

Yes I did. Was quoted 100 bhp. The remap was done on the ecu without the bike to fettle with. Upon installation and duno run got 95 bhp at the back wheel. Bike has keihan headers and akra. Note that duno run was done at high humidity and 35 degree temp so plus one for Geoff.

Well all I can say is if those figures are correct then standard BMW bikes must be about the worst set up motorcycles on the planet when they come from the factory ;-)

Most Shaft driven bikes will lose around 15-20% of their power through the drive train.

It would seem that the GS loses around 25% (110bhp at Crank to 82bhp at wheel), not very efficient no.

So, on that basis, the new WC GS's actual RWBHP figure would be around 93bhp. So a remapped TCGS would actually be more powerful....

Exactly what Geoff told me when I was there in September. He reckoned that WC's were 92 - 95 before mapping and around 115 after so the remapped TC's at around 105 are more powerful than the standard WC.

That's what I have commented previously in this thread but the naysayers poo poo what they can't understand and simply don't believe its possible. My '08 kicks out 107bhp at the rear wheel after the remap admittedly with remus headers and Akra can (baffle out). And yes, I could feel the difference although mostly due to the increase in torque which is also 2k revs earlier in the rev count. I trust the seat of my pants more than any dyno anyway and the difference in my bike was marked in its on road performance before and after.

I would say a 5-10 bhp increase is hard to feel unless you were told so but I do feel it in this case and my results prove it. 100 hp at the back wheel and loads of midrange torque just like the duno results which I did six months after the remap.

the duno results

Is a duno the Cypriot version of a Dyno, that doesn't let you know the results then....

I'm in the same camp, I'm afraid. Something is clearly not right about the before and after figures in my personal opinion, or those of some sports bike Remapped too.

Phone some known engine tuners and ask them to give you 30% more power and see what the answer is.

Yes it is. I do have the graphs as well but can't be bothered. It's a matter of being a satisfied customer or not. I am.

Absolutely - I'd do the remap to get the smoothness and correct AF ratios.
I've been on at BMW for a few years now with regard to the throttled mapping on the bikes - all due to the EC-3 & EC-4 regulations.
My SOHC model was checked and tested on the Dyno along with 23 other GS's ....... all only gave us between 87 & 93Hp .......... this on a bike that was sold to us as a 105Hp machine. The 14.7:1 ratio coupled with poor fuel quality etc. gave us the poor performance - the A/F basically starving the machine. Connected a Power Commander to the bike.... and suddenly there's a difference and the old machine became a new beast at 104Hp..........

On the DOHC or TC we were sold 110Hp bikes........... most only give you around 92-94Hp standard.......... again - throttled by the fecking EC regulations......... and with the exceptional lean A/F no wonder..... Geoff basically remaps the ECU to what it should be - a proper 13.2 - 13.5:1 so now your engine breathes correctly and has the mixture that was originally intended for the machine......... so if you now get your 108 or 110Hp back........ the increase in percentage is correct. Geoff's not done major surgery - just set it to what it should have been in the first place.

For me - makes perfect sense - and my ECU will be on it's way shortly to Geoff to have it sorted.......... smoother ride, no more jerking, no more pre-detonation, better fuel consumption and cooler as well! ....
I'm not concerned about the power gain - just want the engine to run like it should.

Your post, for me has hit the nail on the head.

I'm in Northern Ireland, so a trip to Geoff involves a ferry and an overnight, adding another £250 to the cost.
I'm not interested in seeing the dyno charts or knowing what bhp or torque the bike produces. I just want it running smoother and at it's optimum air fuel mix.

I presume you plan to send the ECU without the bike attached??? I'd be keen to hear how you get on. I'm sure a dyno run can make a difference, but surely not that much. And without the dyno I guess the cost should be down.

I had a TDi 130 VW remapped and was told the map was tried and proven. I could have the dyno done if I wanted, but the map was already written and dyno wasn't necessary. It transformed the car and I neither knew nor cared what the new figures were.

I too may well be posting the ECU off....

Sorry.............but how the fuck would you know ? Did you buy a shite house by any chance ? Bet youd get a surprise if it was dyno tested.

Er, because we have 5 GS's and would you believe a standard LC is much quicker than 3 sorted GS's, one of which has been remapped and dyno'd by Geoff and puts out roughly the same power figures as all those others tested on here, that's how the fuck I would know; and no I am not surprised by the FINAL dyno figure, just the initial one.

The suggestion that a standard pre LC with a remap is going to be more powerful and faster than an LC just makes me smile

Whose dyno?

 

[Phoenix_63]

I can't believe some of the entries on here. I have had my bike mapped by Geoff and it is the real deal. If you need a dyno to prove an increase of this magnitude you shouldn't be riding. The difference is STAGGERING!!! Not just in power increase but in power delivery. If I ever change my bike, it'll be going straight to Geoff. Still, for some people the world is actually flat 'cos they can't see any round bits for themselves and they can beat ABS systems...

agree, best mod have had done to last 3 bikes. Is it quicker than other GS's? dunno, does it transform the bike, Oh yes!

 

[kevmean]

So the answer then IS that as supplied from the factory in standard trim BMW's are some of the worst setup bikes out there ;-)

Strange then that virtually no-one that had posted has mentioned anything about a staggering performance difference, only the smoothness, because there isn't one.

Bring your bike over to the Isle of Man for TT week 2014 and show me just how staggering it is, not only that we will put a few bikes on a dyno with yours and you can guess which power output is yours - because in my humble opinion the remap is somewhat underwhelming on the performance increase front - and the dyno figures do a lot less than prove a point; they suggest something is amiss.

Hi Wilsdorf,
This is something I've been looking at doing for a while now, and my lad wants to do it on his 1150 too, so have been watching this thread with interest. We have over 50 pages saying how good this remap is. I'm guessing you've had it done and it hasn't improved the bike very much is that the case? I haven't read all the bloody pages, but yours is the only real negative post(that I've seen) regarding the remap.What I really want to know then, is who did yours, and what changes with your bike did you notice and I'm guessing you didn't think it was worth the cost........Cheers
