Even if the ECU remains a mystery, I don't see why the right signals going to the actual controller can't be spoofed with a piggy back signal conditioner... this is essentially how the camcon works.
Somebody who's good with electronics needs to tear apart the sensors going to the head
the problem with that is that all throttle control is mainly done with the vvel, so traction control, idle control, general throttling, and everything related to it would have to be controlled by the piggyback. NO way is an emanage gonna do that. the complexity of it is also why it is so frickin hard to crack, nothing is impossible but to companies sometimes somethings just aren't worth there time.
On that note if uprev could make a flash for the ecu to totally disregard the vvel and send all the throttle duties to the throttle bodies, and still have the cam timing system work, that would make this conversion hella easy as well as allow someone to make said piggyback vvel box to just control valve lift based on rpm and have all the air flow duties handled by the ecu/throttlebodies. If they are having trouble doing it from a reflash why not just go that route. That would make putting twinscrew on frickin easy too which would make me happy. This would even allow someone to put a simple lock plate in place of the actuator to hold the vvel at max open to act like a big cam.
