Since 1998 vvti came out which differs to plain VVT where the inlet cam is rotated via three flutes in the head where oil passes. The signal for the VVTi is taken from 2 points The camshaft position sensor and the crack angle.. It is via the comparison of these 2 signals that the factory ECU calculates the amount of rotation in the camshaft.. (which is variable by upto 60 degrees on the UZ series VVTi equipped engines and the JZ VVTi equipped engines) The Motec M400 M600 and M800 ar ethe only aftermarket ECU that controls this correctly. The camshaft position sensor is the same type as used on the later model WRX STi's. I have rung around many ecu manufcturers (Microtech Haltech Wolf etc) and even though they say they can do variable valve timing they can not do infanitely variable valve timing (such as iVTEC and VVTi) There sysems dont utilise the camshaft sensor.. They only switch a solinoid at a specific rpm/load point [Report message to a moderator]
