Summary of change:
This customer project is an Audi 4000q with a BHF code Audi S4 v8 engine. http://lh4.ggpht.com/_w_-TMnbj36I/S01WEvzw57I/AAAAAAAAKHc/vRqInjBE74s/s640/100_3979.JPG The car will be running a VEMS engine management system which raises some questions: The stock engine uses a constantly variable VVT (Variable Valve Timing) system that is controlled via a PWM output from the factory ECU. we have logged how this system is controlled by the factory ECU using vagcom, the output looks like this: http://www.theswansonfamily.us/modules/gallery2/d/70631-1/bhf_vvt_pwm_graph.JPG Question: I have seen reference to full PWM based VVT control in earlier firmwares but it does not seem to be supported in 1.1.6x. Are there any plans to re-introduce this feature?
