I’ve been starting to look deeper into ECU programming. I’ve got all connectors and cables, ordered a solid bench power supply (pyramid 13.8v non-adjustable).
Have collected proper software for VAG and a couple notes on GM stuff. I have 2 spare Vag ECU that match the Allroad, confirmed, and i think the mk4 tdi as well, as well as 3 GM on the shelf. I think 2 of the GM are a match to what’s in 571, but I don’t recall for certain if it’s a blue-green or blue-red. Only blue is used for programming though so doesn’t matter for the bench.
Really wish I could get a solid state drive working in my older windows laptop with native serial port (1). Going to see if my ancient keyspan usb to serial plays nice, or if i can use basic drivers with my Ross-tech cable for all needs. If that works, I’ll be able to move to a newer laptop for shop use (2)
Motivation here is initially that the Allroad needs a clutch, which is an engine-out job. Turbos are also an engine-out job, therefore: what would it take to upgrade turbos along with fixing all the remaining leaks. The answer is a lot, including a remap of course. And tuners are still proud of tunes for a 20 year old car, so what might I be able to do with open source tools? Potentially solve some problems is the answer. And maybe adjust things on the TDI wagon to better suit it’s big turbo. And make VINs match if dumb swaps are ever done.
1) Dell latitude D430; I have tried to ssd it twice, and it won’t see an m2 on the needed adaptor board. It uses a 1.8” disk. I think I verified it is on latest bios revision but I guess that’s one last thing to verify. I’ve got 2 complete laptops and a brand new third battery too. And it’s a nice compact machine.
2) a Dell latitude E4300 has been on standby for a few years. If either of those sun options work well that would let anything up to brand new work. Which wouldn’t be bad. Just bigger than the d430.
