round gauge feature question

[multiplex]

so i know with the newer firmware you can now run boost control and even an idle valve.

i was wondering if by chance there was an rpm based output? or could this be a future option?

I have a buddy who installing the round guage for EGT and backup WB on a BMW motor running an Autronic SM2, but has no capacity to control the single vanos with it.  Thought this maybe be an option
