It's definitely the RAM parameters that I'm interested in. So, theoretically, 20 samples/sec with multiple parameters. Now THAT is logging.
I'd even settle for 10 samples per second. Excellent work.
Out of curiosity - and I'm sure it was probably answered in this thread somewhere - but when you say "CAN logging on Subarus is already fast", I assume this is something specific to the new OP2 standalone beta logger? RomRaider uses SSM over 9141 and doesn't do SSM over CAN, right? Perhaps I'm just confused.
Awhile back I was looking into using UDS service 23 (ReadMemoryByAddress) to grab ECU data over CAN but could never get it to work (I don't think the ECU was in the correct diagnostic mode or needed a call SecurityAccess - not sure.) I never got around to trying SSM over CAN. Duh.
From what you're describing it sounds like your standalone logger is using SSM over CAN, which I believe doesn't support reading of those extended parameters, hence the need for the patch. Therefore, if I can deal with only logging standard parameters with my Cobb maps, the standalone logger is the way to go?
Thanks again.
