What difference with this tune do

[motolink]

I am looking to try to take away the jerkiness at low speed and low RPM improve the low end torque if that is possible.

From what I have read opening up the seconderies will do this but how is it the mixture does not lean out with the seconderies opening right up and allowing more air.

With the secondary closed the computor also holds back fuel acording to the A/F map settings when you allow more air the computor allows more fuel, The O2 sensor will readjust to a degree but don't forget to reset your TPS after you change anything in your map, this allows the the computor to make adjustment from fresh after changes Dougl mentioned in his last post he didn't find any changes in his A/F A= air/ F= fuel which mean no leanness, You have the advantage of haveing a map there that does it all I had to go in and change it all my self, when you are ready upload your map and save it under a name you will recognise and then download the new map finnishing of by resetting your TPS, you won't regret it and it will feel so much nicer at low revs .... no jerkyness just instant power as I said previously take care the first time you ride it, to get used to the more responsive bottom end

Hanson, thanks, bit by bit I am starting to understand thanks to the info from this site.

Does the 12 minute tune come in to play here as well.
