Finished a pcb design for the audio section and ordered yesterday. It should arrive in a week. No time to make a nice case etc but should have something usable in a day or so after it arrives.   I spent a few days working on a spreadsheet to work out what the management/control over canbus looks like for these projects. eg any packet with the first byte as 0xFF will be a command, next byte is  is which command eg test or reply with current status.   Initial setup to give it a canbus address will be via the web page. But after that the ecu can send a canbus packet to change the ID, so if you are in the ecu software or want to change it you don’t have to go back to speed setup.   PCBWay has 24 hour turnaround after they check the design. So far other than the first order it’s been under an hour to be checked and approved. I tried JLC PCB, which is part of LCSC which is a huge parts/components supplier. If they had a better way of combining shipping or parts and pcbs id likely use them more. Other than a few cheap bulk parts every chip and part has come from LCSC.          

I would be the one forum member keen on this! That sounds like my WRX build that is probably on here but years out of date Now it's onto my N/A Impreza! 

Replaced my front pads. Nothing fancy just the ones they have at BNT for the 316mm rotors. The car is starting to have some cosmetic issues sadly and the drivetrain is starting to show its age. Everything from 4k rpm up is all good its the transition onto boost that is a bit jerky. I might go along all the vacuum lines in the next month. It will be a while before I can sort the cosmetic issues but hopefully I can keep the car running good. Its a malaise that I hope goes away soon.    On the other hand I see the Government are consulting to change the WoF frequency for pre-2000 vehicles. In that consultation document is the proposal to bring in driver aid technologies into the scope of the WoF system. I agreed with everything but that part because I see it as a slippery slope toward a California smog test OBD2 reading theocratic regime. Linky for WoF consultation document.   

Could spin one up for everything I've done for posterity, its really just an OEM+ maintenance build with sourcing of delicious things she deserves but never had

Have you got a build thread going for all of this? I'm curious...
