If you want to get rid of the poping back from the exhausts, you need to block the AIS pipe at the air box end. This will reduce the poping back by 98% on 07 to 10 XT's & by 50% on 04 to 06 models. I use a bolt & ground the head round & left a small bit of the shaft so you can get it out of the pipe easily. You then refit the pipe back onto the airbox, otherwise it will suck dirt into the motor.

Hello!

I read everything related to this issue of annulment of AIS and I have a question that is:

* Aborting the AIS, the CO is in the same value found at the time of the cancellation, or CO can re-register, or cancel will obey after the insulation?

Other:

* This complements the AIS and the CO or each system functions independently, if I touch one harms the other or not?

I ask this because the 2 deal with exhaust gases, in my opinion, something will complement ......

Opninones welcome and in this way we learn and improve all .-



My compliments .-

Thanks for your quick response!

According to his response, I understand that annulling the AIS would not change the CO recorded on the board.
My bike has the CO in vivo 17 and 50 meters above sea level, you think of this as well?
Conclusion: I was advised to cancel the AIS and modify the CO?

My compliments .-

Blocking the AIS will stop the popping in the exhaust. What year XT do you have?

My XT660R is November 2007, moreover, is fully factory and without any change .-

I would not set your Co any higher than it is now, as you have a 10 ECU & they tend to start stalling if the A/F ratio is made any richer than 15.

Why do you want to increase the CO?

From what I've read say that the CO works until 2500 or 3000 RPM and then the same 3D mapping is responsible for carrying over these RPM or 18 TPS as well you say, however, if the board works CO values ​​from -128 to 128 I think the value 0 would make sense, but it is not, dropping to -0 is going to jerk the bike with little gasoline, but does not stop at idle, which if it happens by increasing CO +17 +15 values, in order ... a dilemma ...
