Hi i was looking for some help, making my first wiring loom for my toyota corolla . It has a 2zz ge engine with variable valve timing on the inlet and variable valve lift on inlet and exhaust. I have the crankshaft sensor wired to the primary trigger . I have the camshaft sensor wired to camsync #1. I dont know what i should wire the variable valve lift and variable valve timing solonoids to? the variable valve lift solenoid also has a pressure sensor part of the unit for the lift system to know there is correct pressure to operate the high lift engagement. Sorry for the probably basic questions
Thanks scott
Some help with what ecu pins to use
Re: Some help with what ecu pins to use
Scott,
I have a base tune setup from the Lotus 2zz - GE application and it sends a PWM to the VVT-i from any one of the AUX outputs. (specifically AUX 6) This is on the low side of the VVT-i solenoid. The high side gets a steady 12v if i'm not mistaken. I'm not 100% sure on this because I have a lot of projects going on and can't remember how I set this up.
For the VVTL it's just an on off. Toyota has this setup to be controlled from a low side driver but the entire circuit is wired through the ecu so in theory it could get controlled through an H-bridge on the high side and the low side could be constantly grounded.
The VVTL pressure switch is just a fail-safe system to detect if there is proper oil pressure at the top end of the motor. If you want to log this it can go to a switch input but there really isn't a way for the EMU to utilize this in the same way the oem Toyota ecu does.
It sounds like you have your crank and cam triggers setup correctly.
