    with the autotune and it O2 sensor installed you predetermine a air fuel ratio you would like and it works its ass off constantly to provide that. Like Chris says above 13.2 is a good starting point. You can then modify the maps it creates if you like. It is very cool and the high end solution for sure.

    I need to write a summary and details about the PCV & AT at some point, but for the time being:
    Creating a map on the dynamometer is almost always done under acceleration (only).
    That means some 'cells' will never be created in the maps on a dynamometer - the ones at higher rpms at small throttle openings for instance (going high rpms, then close throttle to slow down).
    The Auto tune fills in the missing cells.
    On the other hand, some cells are never populated by the AT - the AT can only fill in the cells where the bike is ridden i.e. personally I would never be WFO at Max rpm, but other people obviously would.
    There are a lot of different theories about what approach to take, the above is my opinion.

    Maybe check out dynojets video library for more info? AT-200 (single channel) would be the one to use for TR650s. Here is an AT intro.

    Chris - Motosportz and Coffee, thank you all for your personal input and experience with PCV. It really helps a novice cut through the mine field. I think it'll be a PB for a while longer, until things get worked out with the idle issue. Also hoping at some point to see an after market pipe. Seems for me that would be a point to make the upgrade.
