OK sorry my bad about the website reference... takes a little bit of detective work. Basically the V-PRO is an uprated version of the IS. The V-PRO contains all the functions of the IS and most of them are enhanced for race/professional usage.
On the V-PRO page it states as one feature:
"AT shift and revision"
* doesn't leave much in terms of detail ehh?
However, looking at the IS page, a description is given:
"In the A/T car, at the time of high load because the knocking which is easy to occur at the time of shift rise or kick down is not caused, engine rpm fluctuation and throttle opening are designated as condition and ignition retarded angle revision of fixed time is done."
Yes, I have talked to Tom @ BD4s extensively about this as well as others who have the units in their cars. Merlin, you are right about the limitations (tuning availability) which is why most of my enquiries went overseas to users who have been running the gear for ages (predominantly UK and Asia).
Trying to stay positive about it... we'll see after next Thursday
