simple question on boost control solenoid

[dannyho]

From the documentation I've read, it seems like in order to use VEMs for boost control you have to give up one of the 8 injector drivers. I plan on running 8 injectors sequentially, so does that mean I'm out of luck and will have to run a separate unit to control boost (or go manual)?

     on a side note, is it difficult to use a VSS input to work as a speedometer? I'll probably be using megatunix though, not megatune

You can use an ignition channel if you prefer.

Can you put your car on the projects page so we know what you're planning on doing?

oh believe me I'd love to, it will get up there as soon as I have an engine and something that looks nice enough to show the public.  it's tough with a 36 year old car.

the info helps, even though i was planning on running sequential ignition too, but i'd rather run waste spark than batch injection.  any info on the speed sensor?

You could use one of the high current ancilliary drivers (Marked as Drive A and B on the pinout diagram) to power the solenoid if these are still available - Are they Rob?  I know I used them both on the TVR. 

I'd avoid the P259 for this, since it can only source 300mA, and the boost solenoid is likely to need at least 1A
