SV650 & SV1000 owners.

Dear all,

a good friend of mine by the name of Kev is a keen biker and an excellent mechanic, apart from being the head of the technical department in an official Volskwagen workshop in Brisbane, Australia, he knows a thing or two about fuel injection, air induction, power commanders and other trickery.

He has his own Dyno test machine and he is always tuning his mates bikes, doing custom maps and finding new solutions to defeat those manufacturers who restrict the new models in order to make them emission rules compliant.

However this morning he sent me an email saying that he discovered something interesting to do with Suzuki's new SV's 650 and 1000.

Below is the message.

Quote Hi,

Been working on a new mod for a Suzuki SV650 & 1000. What Suzuki has done with these bikes is, they'be reduced the torque by retarding the ignition timing in the first 4 gears.

What I have done is make up a mod that makes the engine ECU think it is in 6th gear no matter what gear you are in & it then delivers full power all the time.

This mod has been around for sometime, but others that make this mod have cutting out problems when cold when first started. My mod when in neutral is switched off & only gets turned on when a gear is selected so eliminates the cutting out problem.

Have a good week.

Cheers
Kev


Hope this is of some help to you.

Does it fit a 650Bandit?

Err re-inventing the wheel i think here, the TRE has been around for ages (Timing Retard Eliminator) which does exactly what he says his does, and there are plenty of other electronic 'loops' that do the same thing one example being the Nikko G Pack.

Whilst the TRE 'fools' the ECU into thinking its in top gear, the Nikko G Pack allows it to actually get rid of the torque limiter and use the gear without having to fuel the bike into giving the wrong fuel profile for the gear ;)

If the TRE's and G Packs cause bikes to cut out then it would have been all over the net with complaints, and most people that fit them to their bikes tend to swear by them (especially the Ivans one).

Dont shot the messenger!!!!!


I got this from someone and I was only thinking of you guys. :(

I aint shooting anyone ;)

I am merely saying there is nothing new with this technology and that its not a design or innovation that anyone has simply stumbled upon by messing around with dyno-tuning, when Suzuki first brought out torque limiting ECU software to restrict the power delivery on bikes such as the TLS etc, they didnt hide the fact that they had done it, in fact they told people exactly what they had done to 'soften' the power.

It wasnt long before the TRE's were made available as an extremly 'quick to fit' modification to alleviate it, however most early units were designed to mislead the ECU into thinking its in top gear.

And that is not what you want, you want the bike to release full power as its supposed to do :)

It appears to me that all's he has done is integrated the neutral switching with the unit he claims has a design fault, in short given the TRE a switch that only allows it to become active once you kick into first gear.

I can see how it would possibly benefit someone that has a first generation de-limiter but the new ones that have been out for sometime already work of slightly more complicated electronics that allow the bike to use the ECU properly rather than just allowing it to be tricked ;) :)
