i'm building a d16z6 motor to run 15psi of boost. Would a vafc and msd btm be enough to tune the car. I noticed they don't make a hondata or aem ems for the 91 crx ecu which is the one i'll be using. Thanks

 

no.

 

I would just convert to OBD1 and run Hondata... You would probably be able to get away with a VAFC up until maybe 8psi or so... After that you'll want something like Hondata... Good Luck

 

just get a p28 ecu and convert to obd1, plus then you dont have to convert your existing ecu to hit vtec.
and 15lbs of boost is goinging to take magagement. hondata
vafc is mostly a tuning tool not a management tool, but it can replicate one sometimes
