Hi Erling, I've been studying the Secondary Air function, Autotune algorithms and the interaction of Autotune and any map you have installed. For now, I think the best thing is to learn to save the maps you have for safekeeping and wait a little longer for me to get some feedback on how you may want to proceed.

The subjects I'm looking at now are:
  • When is the Secondary Air Valve actuated? (It seems this will affect Autotune.)
  • How long is the injection pulse at wide throttle angles? (You can't extend the injection pulse longer than the motor rotation period.)
  • Are the base map and trim map additive? (It seems that they are.)
  • Dynojet says that it takes a while to calculate an Autotune correction for a given cell. How long?

Did your tuner disconnect the Secondary Air Valve at the connector or plug it?

On your PC V settings page, what is the delay time that is set before Autotune can start?

But rather than risk giving you bad advice, I'd like to look at this longer and discuss with some other F bike experts.
