Updated code to latest canbus v5.5 functions. These are a little more complex up front but way easier and consistent once working. Not sure yet how well it’ll work for dual canbus networking but that’s not needed for these projects. I was thinking of building some bridges to allow canbus translation between different generations or ecu to body control modules etc. Second biggest things was I found a small solder blob that had been stopping canbus working on one of the boards. Which was a test one, so likely wasted a bunch of time trying some can stuff on a board that wouldn’t have worked.   tried a new library for led display that doesn’t require a commercial licence if you sell anything based on it. This is a real issue when they want thousands of USD for a single licence.   Accidentally stumbled onto a LIN chip for the older K or L line pre canbus that cost 50c US. Makes it cost effective to make stuff for the older cars especially since it’s still in production.    Spent a day getting some parts and building a NAS and making a single storage point for all the work. I was spreading work across a fast desktop, an old slow 2014 laptop (it has all the can bus test rig attached) and a modern laptop.     

Could have been one of those quick fixes on a trip that never got properly fixed.

thats far too sensible an idea... I presume the classics have always had these actually connected? Never actually been dumb enough to try starting in gear...

Try a multimeter on the plug to the pedal. Maybe the switch failed and someone just bypassed it to save $

Googling may indicate its just a bypass to prevent needing to press the clutch to start the car? Confirm/deny anyone?
