coreyb Posted July 6, 2023 Report Share Posted July 6, 2023 Hi I am about to wire up a harness for audi 1.8t and have a couple questions 1. it seems to only have a cam sensor what would be the trigger setup? 2. how to i setup VVT solenoid and how does it work as an on/off switch at a particular rpm? i ask as i know it goes on to chain. Thanks guys for any input Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 6, 2023 Report Share Posted July 6, 2023 What specific engine code are you talking? All of them that I have seen have both a cam and crank sensor. Usually at the flywheel end of the engine near the oil filter. The models with VVT, it is just an on/off switched type, my understanding was it was originally added as an emissions reduction tool, activated during cold starts as a strategy to warm up the catalytic converter quicker, it is in fact also activated under some low load some driving conditions but most say it doesnt have a lot of effect on performance. Connect one wire to ignition switched +12V and the other to an aux output. Set it up as a GP output and use whatever conditions you want to activate it.
