Remap by Hilltop Motorcycles

[Giles]

Is a smoother throttle response and marginal power gain worth the £300-£400 outlay however ?

It is definitely not worth it for the most part. .........

Ummmmm, ! I thought it was worth it. If your planning on keeping your bike for some time It's one of the nicest improvements you can make to it. You'd buy a mudsling? maybe an end can, you'd fritter money away on pointless Touratech tat .... ? , this will be with your bike for it's life, it makes fuelling beautifully crisp and light. Town riding and low rev pick up becomes a delight, up the anti and the throttle is a surgeons knife, that and the fact that you have peace of mind that your bike is not running lean on that ten hour 90mph motor way day. And your MPG will slightly improve. Worth it in my book ....

Bumming around on a couple of other forums it does seem to be that twins respond so much better than inline 4s to this kind of work. Its almost as if they come out of the factory shit or, most likely, they have to in order to meet noise and emission rules somehow and the bike is set up for that rather than how they (the manufacturer ) would prefer it to be?

Yep I'd pretty much agree with that, I think that average (factory) fuelling on fours is much more forgiving than twins. (The old KTM 990's used to have a terrible snatchy pick up ...).

I love twins - they have perfect road manners - great pick up for overtakes, in like a lamb / out like a lion cornering and lovely shut off for 'floating' (back in after an overtake ...). But of all the engine configurations I think twins need to be set up well. Then they're the best motor on the road going ...

I'd agree, although I haven't bit the bullet yet I probably will before spring. I remember years ago I had a CBR600 from new , after the first proper service at around 3k I dropped in to see a mate who was a race mechanic. He asked if the carbs had been balanced and set up properly ....I just shrugged ...and he said lets do it now....bloody hell it was sooooo much nicer to ride afterwards....best 'mod' ever. Of course that just cost me a drink and not £300

So is it the PCV or the hilltop remap then ? If its a case of sending the ecu in the post, how can that be right surely a proper set up would require the bike to be run on a dyno. Or is it just a generic remap ?

 

[Beemerman59]

First off Geoff loads in a generic map - then it goes back on the dyno for some tweaks for each individual bike. Its the last bit you can't do if you send the ECU in on its own. As to how much difference the final tweaking makes I don't know for sure, but with mine it added a few more torques not bhp.

Sending the ECU in the post, with a note of any mods you had carried out (K&N filter, decat etc) will allow Hilltop to map in new parameters from a similarly-modified bike. This is much the same result as if you download a map from Dynojet's site for say "Yamaha R-1, 2004, decat, K&N, Akrapovic unbaffled cans". It ain't perfect, but it won't be far away from your set-up.

Ok thats what I thought. I have a guy about 60 miles from me HMDynos who is an official Dynojet dealer. I think I will fit a PC and have it set up by him. Wont know till the bike is run in and had its first service whether it needs it or not. Chap who owns the business once did a 1250 Bandit for me and the difference was amazing. Slow speed in town became a pleasure rather than a pain it was running so lean it would have destroyed the engine he said. So its PCV for me and a custom map set up on his Dyno.

and the throttle is a surgeons knife

Even after the remap, the fuelling is far from a surgeons knife, and I wouldn't be expecting as smooth an on off throttle as something like a GSXR, or you will be very disappointed. On the Twin cam it is a little better than standard. That said, the difference of a PC on the Single cam compared to standard is very noticeable - I haven't tried a remap compared to standard on the Single Cam though, and have no intention of doing it.

I would also say that the throttle on my standard R12S is just as good as my remapped TC, and I expect it to be better once I fit the PC-V I have in the garage.

Interesting to note the comment on the CBR - as the on-on throttle of the 2000 carb bikes was massively improved with a dynojet carb kit - the following year the FI version of the CBR was launched, and it was down on power and felt like an on off switch instead of a throttle!

As I intimated earlier - we blow a lot of money on our bikes, so why not treat it to one or the other options - but just don't expect the difference you would get from another bike with an extra 30% bhp and 25% more torque, as IME it isn't there. Try a XJR1300 with standard pipes and then one set up with Akras and you know what 17/18bhp difference makes.

As a note.

IIRC, If you aren't happy with your remap, Geoff will refund your money and "remove" his map.

That's 'cos you're comparing a twin with a four .... It's always going to be 'lumpy' ....

 

[DING-DONG]

I had a conversation with jeff regarding his remap against the pcv on my TC he kind of slated the pcv, it really was a one sided conversation and said he could get me more hp from his remaps ! However i went with the pcv route had it Dyno'd @ Junc33 (andy whom owned quill exhausts previously) he knows his stuff and once set up produced 110@wheel, had a nice torque curve and was very smooth, he did say the stock fuelling was very lean.

The bike had a full system with baffles and a filter.


I'm in the process of sticking akro headers on my WC and I'm going to be having some Dyno time .

That's a suprise I'm sure he'll be along in a minute to explain how a remap can yield a 25/30% gain in power/ torque which seems to be what his graphs show.

If it's too good to be true, it usually is. Yes, you can get those kind of gains by remapping turbocharged engines, both petrol and diesel but it pretty much defies the laws of physics to get that sort of improvement by remapping naturally aspirated ones.

 

[sethmopp]

I'm interested in this, not for performance gains but improved running (smoothness and economy) especially as my TC is quite vibey causing a fair bit of discomfort in arms / shoulders. The question is, what effect would this re-map have on current or for that matter future MOTs?

 

[Wilsdorf]

No idea about MOT's, as we don't have them

 

[Deleted account 211025001]

Why on earth would a remap affect an MOT???

Absolutely none whatsoever. ATM bikes are NOT tested for emissions at MOT time.

Absoulutely my point... just want it to run properly - if I wanted performance gains - I'd buy a road bike.....

 

[Delboy777]

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

 

[Blackal]

Why not take the bike out for a run, give it a good work-out, and stop in a layby and fit the module. See what you think?

If you don't think it improves things - remove it.
