Hello. I have been searching for and reading all the postings I can find regarding VVT control. I've read the majority of the related postings. I seems like closed loop VVT went dark about a year ago on the forum. Does it exist yet?
I have been researching in the Arduino forum for VVT control and didn't find what I am looking for/want/need.
I want to build/code a stand alone VVT controller that will allow me to put in a newer MY engine with VVT into an older model year car where its ECM doesn't support VVT. (A stand alone VVT controller that can be operated independently of the ECM, but in parallel.) I have looked at and/or purchased VVTuner and VVT Pro and neither company had any interest in working with me to adapt their controllers to work in my application.
I hope that anyone that reads this post will understand exactly what I want and be able to point me in the right direction.
Inputs to VVT controller:
- Crank timing gear / inductive trigger 36-1
- Camshaft trigger - Odd 4 tooth pattern. (More details later)
- TPS (throttle position sensor)
- Engine temperature - one input used to activate program that will control open/closed,
- Oil pressure - Second input used to activate VVT program
Output
- 12V PWM signal at 300 hertz - Open, Cloose - adjustable output to incrementally open solenoid.
Control and feedback using either a RPM table or perhaps algorithm.
It appears to me that sections of code have been created for the crank trigger, camshafts. TPS and sensors. PWM output exists as far as I can tell.
Would it be that difficult to put all these peices together to build a standalone VVT controller?
