dyno tuning stock ECU?

can you dyno tune the stock ECU ?

any bad side affects ?

is it better than using a power commander ?

what sort of price ?

and most importantly where can i get the tuning done ?


PS i want to tune the stock ECU and not my restricted one, my restriction is up early next year so while i have some cash and have nearly finished all the mods i though i might as well get it tuned now plus i want to do some track days before my restriction is up

ohh and do i really need to get my bike dyno'd?

on it at the moment i have

art stubby race can
factory Pro velocity stacks (mid range)
cut down air filter snorkel
17mm tank risers

in other words not a lot

but before i get it done i might add

factory pro ignition advance (4degre i think)
desnorkel
K&N/BMC air filter

and at a later date (read late next year)
full exhaust system

There's a place up the road from you on the other side of Hinckley that I had mine done: http://www.hilltopmotorcycles.com/

However when I had mine done, he mentioned something about him needing to change it from a 16 bit to a 32 bit ecu (something like that) to be able to make the changes that would benefit it.
Definately better than a Power Commander, as there's no delay for the info to relay back to the PC, and then back to the bike.
Not cheap mind, was £300 for both exhausts to be stubbied, and for the ECU to be remapped, but it did make a small bit of difference - nothing huge though.
Although it did sort out fuelling issues I was having with it drinking oil after I'd put the race exhaust on it.

you might struggle getting on trackdays while your still restricted, i know msv and a few others dont allow it

^ thats ghay

cheers for the info Steve sounds a bit expensive though about £100 for the dyno ?

rolling road tests are around £40- 60 just for a map run

i think my mates stage 1 dyno time (for a bandit) was around the £300 mark 4 yr ago
the ignition advances ain't worth the benefit they struggle when cold and at low revs

thats expensive, my dads bike was dyno'd and mapped for £25 but that was a power commander

and yes just read that about the advancers probs leave it alone for now

I've just read that thread aswell.
there is easier and cheaper gains to be had. Improving the rider is the best one as it allows more use of whats there.

If you're looking for a cheaper option, perhaps a 'Yoshi Box' ECU remap might be better.
(Just found a post I'd previous written around it nearly 2 years ago):

I've had my K6 fuelling altered twice now since fitting my Twin Renegades...

First was at Rhencullen in Hinckley, Leicestershire, about 2 years ago. This used a 'Yoshi-Box' or 'Yoshimura Box'. This was about £65 if I remember right and altered the fuelling up to 5% in areas where it was needed.
This seemed fine, stopped the excessive backfiring (foot long flames out the back!), but didn't get get good economy, and it used to drink quite a bit of fuel and oil!

Then a few months ago I had my cans shortened and had the ecu fully remapped at 'Hill Top Motors' in Earl Shilton, Leicestershire. Cost £300 for the twin cans to be shortened and for the ecu to be fully re-mapped for the new cans.
Expensive, but VERY worth it. Its now better on fuel, doesn't drink as much fuel when cruising, and gives a small, but noticeable, amount of extra power!

The Yoshi box did the job on the cheap, but if you can afford it a full ecu remap is a lot better

I disagree
