air or co2 shift solenoid opening

[servion]

I just finished up wiring my autronic to open the co2 shift solenoid as well as interrput the engine for shifting, and I read that the megasquirt board you guys are setting up has shift abilities.  I have set it up so that whenever I trigger a shift, the co2 shift solenoid will be opened for a specific delay time.

My question is, what sort of solenoid open time are you using?  I don't want to damage my tranny by not opening it up long enough and causing a partial shift.  Is there risk to the trans on my busa if I hold it too long, longer than the engine interrupt?  What sort of solenoid opening times are you guys successfully using, and is it using co2 or air?

i think we are only doing a 50 ms or so for this but i am not a 100% certain
usually a button would set the length of time it is open

i do know we are now doing a gear based shift control also
where we can set the kill time based off of each gear and change just that gear shift if needed for any reason or another
say one gear takes a bit more then another then this is why we have done this
