Sorry, been to the Flat Track racing in South Wales on and S1 excursion to hang out with Daywalker and Toyboy1584...

Now, these are your front and rear maps.

It is the TPS 0 you need to adjust.

TBH, this is an assumption, cos I don't have an 08 bike, however the throttle is closed fully at tick over and the idle stabilisation valve takes care of things.

What you want to do is pull the fuel out, and to do this, the doctor prescribes a value of 10 from 8000 to 2400 inclusive for both maps. Save them, burn to the ECM and go and try. You need to be looking for throttle response if you were to open the throttle on the over-run to re-accelerate as well as looking to see if the popping has gone...

Let me know how you get on...

Ahso...will try it tomorrow an let yer no..!

Perhaps it might be worth playing with decel fuel cut or decel correction first. This might give a first impression how fuel needs to be adjusted and requires not as much effort as changing the maps.

I played with decel fuel cut once, and I must admit I did not spend too much time with it, but I found it made the bike very unresponsive if you rolled the throttle back on again.

Decel correction is merely to pull fuel out if the O2 sensor reads rich, right?

From my understanding decel correction applies, if the bike is in overrun condition. I would have to look at the log files to find out exactly, but it's not closed loop.



Seems that decel correction stop when reaching the upper idle rpm limit.

Edit: default decel corr is 90%, I changed to 75%, but did not notice any real difference when riding. Maybe it's dropping fuel consumption a tiny bit
