I was curious if the newer FI bikescan compensate for lean/rich conditions? Anything carbed you put exhaust on runs lean after wards and the bikes that are FI but have no O2 sensor to adjust air/fuel( except cali ), so whats the effect of A/F ratioof throwing/ modding an exhaust on these? Does it work off of MAP or MAF sensors to adjust fuelor does it not compensate?

 

I'm not sure on the tech aspect of this, but I know that moding will lean your bike out. I placed on a Two Brothers slip on andthe ECU does read this and I believe tries to counter it. The stock ECU does not vary it much though. I had some diagnostics done on mine when I was having problems and the sheet showed that I was within the "operational range" but on the very edge of the lean side.

Anything more, and they saidI'll have to use a Power Commander to get back to where the engine needs to be. Hope this helps.

 

yes it is helpful, I was just curious, I like to tune just for the sake of doing it, but I really dont need any additional power at this point, im not thinking about upgrading exhaust or anything at the moment. Just getting some info about the new toy!
