MMC_Tuner Posted October 2, 2021 Report Share Posted October 2, 2021 Hi there, Another thing on my to do list is to control a factory boost gauge via an aux output (pwm most likely ) to also dynamically move as boost target changes. I don't know if it'll be possible but as a baseline, at least have a boost gauge that somewhat works. It would be great if the needle / gauge output target moved as boost target changes via an AV potentiometer. Here are the photos of the gauge. I'm assuming AUX 3 can be switched a pwm ? Would I need a pwm to AV convertor of any sort ? A good write up here. Probably a good starting point. "Chromedecu.org | Boost Gauge" http://chromedecu.org?page_id=889 Any known feedback? Will it work? Do I have to use a specific output ? My high level drawing attached. More photos Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 2, 2021 Report Share Posted October 2, 2021 Aux 3 will be fine and it should work connected directly. I have no idea what frequency the factory gauge uses though. Quote Link to comment Share on other sites More sharing options...
