Hilltop Eu4

[sven]

I haven't had mine done but I will do. I'll be frank in saying I do not believe it will add 20+hp,that seems ridiculous .
I do believe it'll smooth out the curves to take account of the Akra exhaust and remove some of the restrictions placed upon BMW with the way are forcrd to map/fuel the bike for type approval etc.
I'll get it dyno'd before and after elsewhere for comparison purposes.

I've said the same thing in the past. The "after" figures are believable, but I'm very sceptical about the "before" ones

I agree with you Sven, and I've had a few bikes Hilltopped.

Here you go, a before run and two after runs on the same chart.

Fuck me, thats rich.
Admittedly a wot run doesn't tell the whole story.

What are they like on fuel afterwards? Do you have a black sooty tailpipe?

That would seem to indicate that you are now bunging in over 30% more fuel over standard.

^ Looks super rich to me. Economy will hurt significantly if riding the bike to leverage the extra power...

Is this empirical enough?

I've just ridden a regular 95 mile route there and then back again on motorways using a cruise control set at my normal speeds (I.e. exactly the same way I do every time I make this journey). There is a 50mph average speed area and all non-motorway sections are dual carriageways. I took the usual amount of time (within 2 minutes of my average of 1:45 each way) but I used a significant amount less fuel. As I covered the same miles, in the same time with less fuel, my conclusion is that my engine is more efficient. Am I wrong?

I have ALL my fuel consumption figures for this bike since March 2014. It was easy to check my consumption for this journey every time over the previous 32 months and this was easily the most fuel efficient journey to date.

So in summary: Run rich under WOT to provide smooth out delivery (same as when running a 'wet' map on sportsbikes), and lean out the bike for economy under partial throttle (ie, on Cruise as per above)....

No matter what those who have had their bikes Hilltopped say, you won't accept their bikes have been improved. Until you've had yours Hilltopped you are simply speculating that there is no improvement. Get your bike Hilltopped and if there is no improvement Geoff will give you your money back and revert your bike.

New dates available in March and April, anyone interested PM me and I'll let you know when.

No point putting the Graph up for me I ain't got a clue what I'm looking at.

Exactly. I can't understand why the naysayers are still in here. Not interested; off they should go then, nothing to see here!

 

[Toddmeister]

For comparison, here's mine from 3 years ago on a 2013 LC so not EU4. AFR looks spot on! When I had it re-tested a year later the guy at Powerbiking said the fuelling was spot on and there was nothing he could do to improve it. My fuel consumtion dropped 5-10% after Hilltop, presumably due to a more efficient engine.

 

[DING-DONG]

I'm suspicious of the before because the graph does not really translate to how they ride, the before graph looks awful, when I had my Ktm done it made 147 stock, being sceptical I no someone else whom had the same bike and took it to a different Dyno and that too made 147 so must be right its just the lines are fecking awful .

 

[Nutty]

What we can deduce from all the graphs is that the EU4 bikes, after Hilltop, are down about 3-5bhp on the EU3 model, after Hilltop. I'd challenge anyone to be able to actually notice that though.

 

[DING-DONG]

I recon there's limitations regarding how much an outsider can program especially the level of adjustment of fuel, this being a minimum of 5% increments so easily end up being rich ! also advancing the ignition 7% degrees and adding fuel would get similar if not the same figures ?

I genuinely sit on the fence regarding Hilltop, it's deffo made him ££££££££

I just thought I will do a very quick reply to some of the questions and answers that have appeared on the forum regarding the fueling the most important thing to remember is load I don't run a no-load dyno all of the runs on the graphs that you're seeing here are under load the graphs that you see that have been posted on here are from zero throttle position to 100% throttle position so as you would appreciate an engine that is under load immediately requires more fuel than usual if you were to do runs which have a steady throttle opening you will see that the field is dramatically different due to the load and throttle position this all has a direct relation to the performance of the engine if anybody is interested in learning more about this I will be holding an open day in the future where any questions regarding The tuning of these engines I will gladly answer on the day
take care Geoff from Hilltop Motorcycles

Well that rules our resident fuse tester out as apparently, he knows feking everything.

Good man, Geoff.

IIRC the last 'open day' was pretty much organised for his benefit. Naturally he didn't show............

I attended the last open day and Geoff was very open and help full, happy to explain his methods.
I do not doubt his work I am genuinely interested in correcting the fueling on these bikes.
It is just that I would like to see the AFR at normal road loads.
Unfortunately being inquisitive sometimes comes over as being contradictory.
I would like to attend the next open day to glean a little more info.
My main problem is under full throttle from low speed in 6th gear the AFR goes rich then for some reason goes lean ( nothing to do with knock sensors or Ignition timing) I cant find if there is a load sensing map that it defaults to? Any Ideas ?.

I can't make it to an open day from the US but would attend if I could. On the graph below, I see AFRs that we never experience in the field, with Wideband O2 sensors installed ahead of the catalytic converter. The graph of "Before" AFR is between 15 and 17 at WOT. On the street, every stock BMW bike I've measured is between 12.8 and 13.2 during a quick roll-on to WOT and for the first few seconds we see AFRs of 12:1.

What condition on the Dyno led to the leaner Before AFR graph?

Looking at the section from 30-100 mph, it appears that you briefly get an acceleration enrichment, then it appears that the bike reverts to closed loop at about 14:1 AFR until about 50 mph. From 50 to 100, the AFR steadily richens to 12:1, at around 90 it again is reverting to 14:1, looking like Closed Loop there, curious.

I had my old 2013 S10 done at Hilltop.

TBH the figures dont bother me at all..its the rideability. That certainly improved..especially on the twisties in Spain and Portugal.

So the Hilltopping work for me!

FYI before bhp 75 and after 94. At the wheel. Also when touring Europe 2 up fully loaded my mpg went up slightly too!

I will definitely be getting my Eu4 GSA done at some point when there's less salt on the roads!

Is that your only date for April?

Tentatively pencil me in if you can, subject to my bike arriving from Germany.
