VAFC II, any one tuned one?
Whats up, obviously Im new to the forum, I dont have an Integra, but I do own the heart of the beast and it tourments the engine bay of my 94 civic. To keep this from sounding like an interview or a singles ad Ill leave my personal details to who ever ask.
I recently installed the VAFC II and theres a little vagueness to the manual as far as setting the throttle point and the V-tec unmatched. From my deductive reasoning I assume the throttle point (percentage) is at what point the VAFC II maps take over my ecu's maps and at what throttle percentage the new maps take over. I know that there are seperate maps for narrow throttle and wide throttle, im curious at what point the factory maps need reconstruction.
V-tec unmatched: For compensating the difference in V-tec engagement between the ecu and the controller with fuel. I understand that, for instance the v-tec is set for 5,000 rpms and the ecu is programmed for 6,000 rpm you need to increase the air correction and fuel in order to take advantage of the earlier egagement. there should be an equation of some sort to figure out this percentage but there isnt, well one that works, the equation in the book only works for a later v-tec engagement. I plan to dyno tune this later but Ive been playing with it on the track and the street trying to fulling understand its parameters before I trust someone tunning it for me (shops are shady in texas). any help, dyno sheets settings etc. would be greatly appreciated.

thanks guys!!!!!
