Does anybody know if its possible to run a p74 non-vtec (94 integra LS) program on a p28 (sohc vtec) ecu?

What i want to do is burn a LS uberchip (boost) program onto a p28 ecu. But im not sure if it will work? Can a p28 run a non-vtec program?

Hondata says they can do it...but i dont know what that involves?

thanks,
liam
