So I met up with @
sam1337 today to check out the issue. Here are my minor observations:
- The car "idles" at around 2.3k rpm when I saw it. Plugged in obd sensor and it is reading approx 850rpm
- Engine is running at normal revs reading the value from torque
- Disconnected amp from battery and issue still there
- Cable from the amp goes via the right side of the car -> to the front -> to the left and then through the firewall
- When the car is switched on, the tacho sits at ~1k rpm whilst the engine isn't even started. I thought it was weird as my mps3 sits at 0 rpm whilst the car isn't started
- final thing, when you switch the car off the needles jerks its way back down to 0 from 2.2k. Its really weird haha
Thats about all I could do to help Sam out today as I only really had my obd2 bluetooth dongle. It does seem like there is an issue with the instrument cluster.
