    Loaded a Tune Ecu tune I got from Hanso for my 2008 with Ramair , Viking Header and now single Viking silencer.At the time it was for header and Staintunes. I have PCV with autotune which I loaded with a zeroed tune in the PCV and Hanso's AF table in the autotune.

    Everything seems good except in the 0 to 2 throttle position where the Auto tune will not function. Lots of time is spent in this range and the Rocket is running ragged. Any suggestions any other TuneEcu tunes I could run for this setup. I went in to PCV and reduced values in the 0 to 2 TPS range by 5%. This helped smooth it out.

    Should I just keep reducing fuel in this range until its good or is there a different TuneEcu tune someone could recommend. I was looking at A/F on the TuneECU screen and still showing mid 12's at idle and 1% TPS

    Love the Viking Header/silencer combo, thanks again Paul.

    Kim.

    This is the hardest area of the tune to get “just right”.

    It needs to be done in TuneECU in the L tables to really do it right.

    Thanks for the quick reply. Any suggestions on how to go about that. I have never edited any fuel values in TuneEcu.

    You need to either learn the relationship between vacuum, throttle position, gear, and rpm or use a dyno, two best ways.

    Learning that relationship takes a lot of data analysis lol, hours and hours.
