Remap by Hilltop Motorcycles

Is there a reason why the 'before' graph starts at 2000rpm and the 'after' graph starts at 4500 rpm ?

It would be nice to see the 'before and after' power and 'before and after' torque curves on the same graph (for a Twin Cam) - does anyone have that ?

I have before and after overlaid on one graph for a 2008 which is going to be pretty similar. If someone can give me the heads up on how to post it I will have a go at doing so.

'cos the power scale is different on the 'before' and 'after' I'm finding it hard to compare the 'smoothness' of the trace. Is that really such a big dip before power and torque come in on the 'after' graph and can you feel it

Andres

The different scales do make it difficult to compare. Even more so when you look at the fuelling scales.
No - no perceptible dip in power - feels smooth right through.

I have scanned in my graph but it is too big to upload as an attachment. Anyone know how to resize it, if thats what I need to do?

If you want you can email me the scans/jpegs and I'll re-size and post them up on the thread.

Seahorse's Dyno Chart

That's what I'd like to see but for a Twin Cam

+ 1

Ideally with the power and torque on different graphs to make them easier to see

I'm not that fussy same graph is fine for me.........

Cheers Andres, top man.
After the final tweak we got 103 bhp and 84 ft/ lbs but the graphs looked the same otherwise. Careful study shows the boost in midrange but what really counts is how it feels on the road. Look also at the air / fuel ratio at the bottom. I wouldn't expect any significant difference for a TC.
Haven't heard of any disappointed customers yet, but then us 1200 owners will fall for any old nonsense

Thats a whole chunk of extra torque low down, which has got to be good. Mine's in Saturday

Yep those are good results on the Single Cam - boost in power and torque accross the rev range

Need to see the same graph for a Twin cam though - the engines different so can't assume it's the same result. The accelerator mod seems work on the single cam and not the twin cam for some reason.

Need to be sure there's no dip in power at low revs as that's where you spend a big chunk of your time in the real world

doing a Twin cam as i type this msg will upload it soon

 

[APE]

Thanks

Not being cheeky can we see it from 2k rpm please

A couple of charts (Twin cam) from Geoff at Hilltop

Andres

 

[neoviper]

yes i have ,you can see them now at http://www.facebook.com/hilltop.motorcycles

thank you Outtomunch

 

[APE]

Very impressive

Why the dip in torque around 5k - can that be tuned out ?

 

[neoviper]

yes ,well i must do sum more work have fun chaps

 

[APE]

Ha ha have a good one

Just had my twin cam remapped at Hilltop today.
For those that are interested i am pleased to say it was well worth the expense and effort.
The actual graphs have already been posted earlier today, however how it performs on the road is of more interest. My bike is stock running on 95RON fuel
and on a varied route home of 78 miles it averaged 57.6 mpg at 48.8 mph average. This included max acceleration tests through the gears and a fast run up to 120 ish. This was accomplished with ease compared to stock. Also traffic runs through Wolverhampton and then country lanes home. The best ever mpg prior to remap was 55,2. Bike is now much more lively and pulls like a train.
A GS will never be the most exciting thing to ride but with the combination of better power output and all day comfort, its hard to beat.
