Hilltop Motorcycles fact or fiction

As a potential remap customer, I don't understand why Geoff doesn't explain what he actually does when he remaps (he has posted on this forum before). There would be no need to divulge any trade secrets, just outline the changes he makes with his software. This would clear up the whole issue and give everybody complete faith in the service he provides - it would be great for his business.

Speak to him then as he will happily explain what he does (without divulging the detail or 'secrets' as you put it).

Given how busy he is with both road bikes and race teams I think he's already doing something right re the business.

Geoff does explain it great detail when you're there ......hundres of programming hours 'reverse engineering' the manufacturers ECU programming to see how they've set them up to meet the Euro emissions regs, then re-programming for optimum performance.

Well over my head - but I know it worked on my hexhead GSA .......and continues to work ....anyway, I'm off to ride it now :D
 
Could you imagine the shit storm that would ensue from nay Sayers if he did actually post up though?

I'm happy booking my 3rd remap with him . It's crazy the amount of posts generated (this one included) on the Hilltop subject.

To me, an honest bloke, found a niche, invested time, money and effort in it to get it to the point were it sells itself. Good luck to the man.
 
I expect he does indeed visit here every time he needs a good laugh...

The evidence appears to be overwhelming.

Good enough for me.
 
I'm booked in on the 16th July and can't wait. I've had three cars remapped (not by Geoff) and it's always made a massive difference.
 
I mean this in a caring and supportive manner..... But,who the fcuk are you- to tell anyone that they have "missed the point"????

then go on to say what is important to you................:blast

How about you let each individual decide - what they are looking for?


35yrs......... :rolleyes:

My post was a reaction to Navejo's post of being in France with a blown engine, I would be seriously unimpressed if that was me, perhaps I could have worded it differently.

I was completely unaware of the fueling issues when purchased my GS, my post was driven by wanting to highlight the lean running issue to those who are not aware and the potential for an expensive catastrophe. Perhaps a sticky to explain the whole issue would be of use?

My bike has been remapped and I am more than satisfied with both Geoff's explanation and the results. My reference to closed loop was perhaps misleading, my understanding of Geoff's explanation was that his software aims to achieve an ideal AFR of 12.9 to 13.

Although I don't see the "evidence", I hope you guys will all join me in a laugh today while I wait to hear from Geoff. The question at the outset of the thread was "... Fact or Fiction". First a couple definitions:

Fact: a truth known by actual experience or observation; something known to be true: Scientists gather facts ...

Fiction: literature in the form of prose, especially short stories and novels ...

This thread is now 15 pages long with 227 replies. After reading all the great short stories but not finding any measured observations, here's what comes through in the narrative:

--Hilltop is a respected company and Geoff is earnest and sincere
--Customers who have purchased Hilltop upgrades are very satisfied

On that basis, it seems that "fiction", used in a good way, best answers the original question of the thread. After all, don't Shakespeare's fictions inform us of some of the greatest truths? Of course Isaac Newton used a different method of factual observation to quantify and mathematically describe the world and were indebted to him too.
 
As we're getting into definitions ...

The English language word "pedant" comes from the French pédant (used in 1566 in Darme & Hatzfeldster's Dictionnaire général de la langue française) or its older mid-15th century Italian source pedante, "teacher, schoolmaster". (Compare the Spanish pedante.) The origin of the Italian pedante is uncertain, but several dictionaries suggest that it was contracted from the medieval Latin pædagogans, present participle of pædagogare, "to act as pedagogue, to teach" (Du Cange).[1] The Latin word is derived from Greek παιδαγωγός, paidagōgós, παιδ- "child" + ἀγειν "to lead", which originally referred to a slave who escorted children to and from school but later meant "a source of instruction or guidance".[2][3]
 
Just visited Geoff and he worked his magic on my 2012 TC, all I can say is it feels like a different bike. It is so much smoother, more responsive and it makes me smile even more. I don't understand half the blurb in these posts but what I can say is that Geoff took his time to explain what he was doing in simple language, seemed a very genuine guy and I would have no hesitation in going back, money well spent I think. I guess it's all about where you want to spend your dosh and who you trust and as you can guess from this I am happy, cheers Geof!!
 
Roger 04 RT, I tend to agree with you. I read many of your posts. Years ago I bought a intake temp change module for my2010GS , and it did very little at first, and nothing quantifiable afterwards. I think it comes much down to "I paid for it and I do want it to feel better".

But I also have a ('07 BMW 320d) turbo diesel car, and here the changes with a remap (not tuning box) are very noticeable even at low/part load. I take the difference is the diesel has no closed loop control?

Here's the question: When having access to the maps, why can't the Lambda reference values be raised? I think I understand it reads the value of the sensor, being a voltage, and compares that to where it wants to be. If one could change where it wants to be?

regards,

Martin

I'd say the chuffing great turbo and modifications to boost pressures in the map make it noticeable :)

Your post contradicts itself.:blast

Oops valid point. The diesel runs with excess air, and the turbo ensures that too. Lambda not relevant. I still don't understand why the fueling tables can't be changed on a petrol to look at different Lambda values

For some reason diesels (were at least) set very conservatively regarding fuelling and turbo boost. I expect these days, they are making better use of what they've got especially with the very tight emission rules.

Googled "Lambda sensor voltage curve" and found this

By the looks of it the O2 sensor gives a step change at a particular exhaust oxygen content. Set that value high and the engine runs weak (to allow excess air down the exhaust). Set it low and the engine runs rich. Presumably the fine tuning is done by the ECU map.
