Glad I found this thread. Joe - are you in the states? I'm in NY and planning on doing a JZ series swap (possibly VVT-i) and it would be good to have a friend to bounce ideas off of. I don't want to hijack your thread but it seemed like a good place to put this info WRT megasquirt and VVT-i control.
Here is some info on VVT-i and standalone management systems, the first link has a lot of great info:http://www.toyotagtturbo.com/forums/sho ... ntrol-VVTIhttp://www.mr2.com/forums/beams-owners- ... beams.html
Conclusion is that VVT-i can be controlled with a state switch (on/off) instead of continuously variable, however this is far inferior to continuous control, which the stock ECU offers and is based upon a function of many engine input variables and is not 100% intuitive as it serves to enhance torque and not high end power.
Is anybody currently CONTINUOUSLY
controlling their VVT-i setups? If so, how did they arrive at their mapping strategies and hardware setup?
