Can the ECU be Remapped?
 

Hi All.

I was sure I read that the SV ECU can be remapped so you don't have to buy a Power Commander. I phoned Double Take Dyno in Southampton yesterday. They said they had never heard of it and that I needed a Power Commander.

It's a K3 model. Any ideas on this people?

Thanks
Tim.

Double Take Dyno are lying (or uninformed...) as you don't need a Power Commander.

At many Dyno centres, they can offer you a 'Yoshi ECU Editing' thingy... not 100% of the name now, but basically it's about £60-80ish, they put it on a Dyno, plug your ECU into a computer, and they can alter the fueling where needed by up to 5% either way from standard.

This is ideal for anyone who's put a free-flowing exhaust on and wants to get the fueling sorted out as cheaply as possible. I guess this is what you want it for?

Edit: I think it's called a 'Yoshi Box'!

steve jordan motorcycles can do it...

What ^^ says.

Double Take possibly just are not aware of it.

There are three systems.

Yoshi and Teka boxes can be used although they have a very limited range of adjustment. Costs for this are about £60-£80.

We use a system that can remap the stock ECU with multi positions and throttle openings creating a far better map. Plus because your utilising the bikes own software it works alot better than using an aftermarket box such as the Power Commander. Plus it works out cheaper as you dont have to buy the PC. Costs about £120.

Its only available for Suzuki's at the moment though.

Just out of curiosity, what system is that?

Thank's for all the info.

I found a place in London using Google that said they can remap the standard ECU.

Steve Jordan sound promising. A bit far to though as I am near Portsmouth. I'd enjoy the ride though.

I need to check the valve timing, throttle balance and TPS adjustment before doing anything else. In case I got anything wrong after taking the front head off.

What kinda system does the Stock ECU navigate on ?

Speed Density based , ie MAP sensor or MAF sensor type... or eve something completely different ?

Re: Can the ECU be Remapped?
 

Not that I'm an expert on the pointy, but I believe its a pressure sensor in the airbox

Re: Can the ECU be Remapped?
 

Tim - Steve Jordan's could check all that for you at the same time ;) The ride up there is no problem, you can either blat up the A3 or take the twisties, when I went up there I borrowed a courtesy bike and nipped up to Boxhill for a burger :smt023

Re: Can the ECU be Remapped?
 

if the sensor is in the Airbox , it would sound like a MAF sensor type setup (since pre-butterfly is always Atmospheric unless uve got a turbo with a blow through system , and a MAP sensor type requires the sensor after the butterfly to detect Vacuum as well as Atmospheric or positive).

Luckily , there not to hard to trick into changing... Im guessing thats how these ecu fuel modifiers work... piggy back style.
