No matter what the question is, the answer is always more horsepower!

Most tedious part is inputting all the calcs for each PID. Once it is in though, I can use it for VPW as well.

Re: ELM327 Software Development
The Startup IAT calculation is a whole world of weird!
FB38 = Start Up IAT = -48dec where 0020= 1degC, 0040=2degc, 0100=10deg, 7000=1124degC, 8000=-1285degC, 9000=-1124DEGc
It goes super weird after 8000.
The ecu's actual response is FB38
Im not 100% sure, But Im guessing (like the other temp sensors). Its going to start at the -48deg mark which is at FB38.. and as the temp increases, the FB38 will increase to FFFF, then it must roll over to 0001 for 1deg ect.
the calcs kinda make sense, caclulating 0Deg would be (I think):
FFFF-FB38 = 4C7
4C7 * (10/&H100) = 48deg
Thus -48 + 48 = 0
Or, Tempvalue = -48 + (&HFFFF-&HFB38)*(10/&H100) = 0deg
FB38 = Start Up IAT = -48dec where 0020= 1degC, 0040=2degc, 0100=10deg, 7000=1124degC, 8000=-1285degC, 9000=-1124DEGc

Re: ELM327 Software Development
CAN Live Engine data Reading... Tick!
VPW is a much bigger pain with setting up DPIDs.. let alone having to also incorporate DPID setup changes on the fly with gauge changes. Soooo, Im thinking, for the sake of my own sanity, Ill stick with the single enhanced pids requests.
If anyone can think of/post up any gauge controls they would like to see then let me know. Im am looking to making a simple toggle switch for those enhanced PIDS that require an ON/OFF status.
