Hilltop Group Buy

Thing is - of all the people who have had a trip to Geoff - I've not heard of anyone who has claimed:

"Holy Fcuk! The consumption is way up, and there is a stink of fuel!"

"The bike runs worse than when I took it in there!"

I know that the bike I have, with the high performance exhaust and air filter - was running ultra-lean and almost unridable. Thought about PC5, FRK Module, Rexer - and decided on Hilltop. Bike runs tip-top now, with no concerns about fuel consumption, loose connections or subsequent over-writes of the mapping...............

If I get time, I'll pop along to another operator for a dyno run - just for fun

You tell em Geoff .
I was thinking of looking at a new WC before you remapped my twincam however your remap made such a difference to my bike that I see no reason to change it now.
I can't see how people can moan if you offer a money back guarantee .
Bloody long way from Glasgow but well worth it.
Cheers

I had my 08 GSA remapped by Geoff nearly three years ago now. Still very happy. Would not hesitate to have it done again on another GS. It quite simply transformed my bike. My brother had his identical model done at the same time, I have never heard him say anything but praise for the results.

So if you don't trust him or it, or just don't want it. No problem. Don't have it done, simple. If you had it done and not happy he will take it off and refund you. What more do you want ?

Why all the sniping ? Nothing better to do maybe?
 
One would have to question why, someone who does not own a GS would register with a GS forum, and make his first post a long and rambling complaint about someone who offers a service which has been taken up by and revered by many forum members ?

The man can't be any fairer than to offer a full refund if you're not happy with the result of his work. In this case he was given such a refund so I don't see what his gripe is.

As for letting his missus do most of the talking, sounds like she may have been the reason for him taking it back, and he's now trying to justify to himself the reasons for letting her do so.

Anyway, I've got the Stelvio booked in for the 26th. No, I won't be taking my missus.

I'm booked in on Wednesday for my GSA so will report back. I'll bring extra biscuits for Geoff..

Should that be "...I'll take extra biscuits for Geoff"?

If you were communicating directly with Geof then 'bring' seems fine, but if your telling everyone else then surely it should be 'take'?

He has a perception that he has been "wronged" and decided "I'll show you! I'll post my version of events on every site I can - Hah! - You'll be sorry!"

Or maybe his wife made him do it? :augie
 
...

The “unmapping” at Hilltop in July took two hours during which Geoff again did anything but work on the bike – he spent perhaps 20 minutes max actually doing anything with it. At no time did he ask whether he could adjust the mapping to address what I felt were the deficiencies in the remap. Just before processing the refund Geoff again tried scare mongering about how lean it was now running, with dire warnings about it burning valves, holing pistons etc etc. He even showed me a new version of my dyno charts adding an A/F graph which showed off-the-scale 22:1 all the way up to 4500rpm (which was odd because I don't think that a petrol internal combustion engine can run under load at over 22:1 and will seriously misfire at 16:1). I was then asked to state my acceptance, in front of the cctv cameras, that Hilltop accepted no responsibility if the bike went bang. I was also informed that there would be no record of my bike having been “remapped” at Hilltop. Geoff was then happy to let me ride off on the bike…

Recent discussions on this forum indicate that nobody is sure what Geoff actually does to remap a bike ...

There is no reason to fear AFRs that are above 14.7:1 for an inertial dyno test. They are solely due to conditions on the dyno and bear no relationship to what your bike is doing when you ride it on the road.

At the start of a dyno run, the AFR should be its closed loop value of 14.7:1 (unless you runs LC-1, LC-2 or AF-XIED, when it will be lower). If it is higher than that it is due to the bike having been decelerated by the dyno roller and going into fuel overrun cutoff, shutting off the injectors and drying the fuel (that is there in normal operation) from the wall of the throttle bodies and backs of the intake valves.

No one should be concerned that valves will be burnt or holes in pistons from dyno run AFR reports. The hottest exhaust gas is from operation at 14.7:1. Richer or leaner results in lower EGT.
 
After visiting Geoff today I'm very happy with the results. Started with 78bhp and 62ft/lb and after a few runs left with 99.9bhp and 77.6ft/lb. My thanks to Geoff. Happy days...
 
We have just booked two bikes in at Hilltop(GS's), having phoned around, and made enquiries with BMW about an s1000rr race ECU, the dealership told me, don't waste your money buying an expensive ECU, take it to Hilltop.
So in simple terms for the non believers, BMW Dealerships are recommending Customers to go to Geoff.
There are many many satisfied customers.
Race teams use Hilltop
BMW recommend them.
One person is not satisfied, is offered his money back??
No brainier".......................

I appreciate what you are saying, but a chap at a dealer suggesting you go to Hilltop is a world away from "BMW recommend them."

I am sure Geoff does some really good stuff and I suspect I will pay him a visit at some point to improve my RT LC. I just struggle when the boundaries between fact and folklore are blurred. I mean this point generally, not in response to Tony's post.

I read everything you guys were writing about Hilltop and came to the decision to go along three weeks ago with my RT LC!
Could not be happier with the results. Another happy customer. Thanks Geoff

roger i must correct you that only applies on a dyno setup that has no load control and temp control and air pressure and of course lastly humidity and rad
i use a dyna pro t62lcc in a fully controlled ram air custom made dyno room i use 3%pua load
hope this has been some help to you
 
I am trying to free up the 5th of September so I can trundle over to learn more from Geoff. Maybe he can squeeze in my RT LC for some love on the day. :)

My main concern would be reduced mpg / tank range following the remap, but generally this does not seem to be an issue. Would be good to get something definitive so I can grasp what is happening, though. I am a bit slow in my old age. :rob

I'm going to give a full statement when I have time
Suffice to say I was there as well !

Geoff, That's a good clarification that you have a load, thanks. Many dyno runs show those high AFRs until the bike hits 3000-4000 RPM. Those are clearly due to deceleration going into the pull and are artificial. I documented this on another bike at another shop by capturing GS-911 data throughout the dyno testing.

With load dialed in before the pull, the bike should be "cruising". That being the case the bike should be in stable closed loop at 14.7:1, then head richer from there. When I make an acceleration "pull" on the road, with actual air and rolling resistance loading and my Wideband installed ahead of the catalytic converter I get the following curve. Because my bikes run shifted closed loop lambda I'm at 13.8 instead of 14.7 at the start and end of the run.

Closed Loop Lambda-Shifting coupled with your ECU tune would make a dynamite pair.

reply to papasquelch

Ok guys here goes with my reply to papasquelch
1. I was there when you took the bike back
2. I have to disagree with your statement "The workshop was an untidy mess and didn't look like a professional tuning establishment" It in my opinion was NOT.
It is after all a working garage and did NOT look like Steptoe parlour
3. "However as the holiday wore on I struggled to notice any meaningful change in the bike." This is NOT what you said to me ! You said that on your other bikes there had been a VAST improvement e.g your aprilla and that the Yamaha did not show such dramatic improvements you also stated that "this might be due to the Yamaha being better set up initially than the Aprilla"
This two statements that you made to me indicate that there was an improvement to the bike but maybe not quite what you were hoping for? And that there may be a reason for this but out of Geoffs control .
At NO point while I was there did Geoff behave in any way either awkward nasty unpleasant or anything but accommodating.
On the other hand you came across as "The font of all knowledge" with huge experience which may or may not be true ?
4.I cannot understand HOW YOU HAVE THE NERVE TO COMPLAIN ? If you buy a power commander and are not happy you do not get your money back ! If you buy a new exhaust system for over a grand and are not happy YOU DO NOT GET YOUR MONEY BACK ! Geoff has faith in his ability and is good enough to give a MONEY BACK GUARANTEE IF NOT SATISFIED you were not satisfied and you got your money back ?????????? What's the problem ?
5.I then take issue with you in trying to damage Geoffs business after you have had your refund THIS IS JUST SPITEFUL if he had refused a refund I would be on your side not his.
6. You now present yourself as a tuning expert if you are so brilliant technically why can't you do it yourself ?
FINALLY
I an NOT an expert and I am VERY hard to convince of anything if I am not given all the facts but you cannot complain of a service that offers you a full refund if not satisfied what else can he do ?
I am very happy with my bike how it runs (I have a 2011 triple black) and my main reason for going to Geoff would be the lean fuelling issue any performance gain or economy gain would just be a bonus.
Also WHY would you expect Geoff to give all his tuning secrets away ?
