does a mode 9 request not accomplish that?

i've looked into this before.....

a couple posts in there should be helpful.

curve is going to be dependant on exact pulldown value and the sensor(or wideband controller or whatever is being read) itself.

typically, the a/c pressure sensor circuit is setup the same as a...

as has been simulated and then tested real-world, the pulldown resistors in the A/D circuits can have a rather large effect on the linearity of a sensor read. either need more drive current(op-amp?)...

some example target idle commands are in the ADX.

been a while, but it should, in a few different formats. it's so much nicer to work with inside of IDA though... i'll see if I can find a reasoning behind it and get it functional.

I'm running 6.1 now but those were originally started with 5.5 IIRC. I upgraded them from 5.5 to 6.1 without issue?

this should do it. default views should open up to the areas I was just playing with.

Steve, you use IDA? I can upload both halves of my disassembly, be easier to explain things that way. my P66 V6 ADX has some mode4 stuff in it already but I have more defined in the disassemblies...

requesting a slight edit on my name... close, but not quite.

also, I forgot to grab the libraries first and it took a few DLLs before realizing that, but this looks damn promising.... I might be...

having things setup for mode 3 like that, you're essentially working with an OBD2 style PID request string, which has its significant overhead drawbacks. sending a request for 6 bytes is going to...

neat, basically a full mode4 controller. I've played with those commands quite a bit for my applications, I do believe some code expects them to keep being sent for keep-alive purposes... in any case...
