Alright just checked with e-manage... I figured out how to force the car to go into v-tec and still have your speedo and everything else working without the need for microcontollers and so on. I'll be making another harness in a few with this harness (removing the controller)that chief had in there originally and test that on my car as well as Kris' (99MBPTL):


Basically, here's how it goes... for e-manage, although you have the regular harnesses that run to it, you can actually manually engage vtec through wiring up the solonoid that controls the high-lift lobes to the emanage's subinjector harness. In this way, in the subinjector map (usually an option, not needed for our FI setups; only the "additional injection map" is used); the subinjector map's values would trigger the solenoid to lift the lobes and make vtec possible. Once this happens, the values from the additional injection map will compensate fuel for the sudden volume of air to avoid leaning out.
