Pids

[herraihme]

hello.
i have vectra with me9.6 ecu and af40 gearbox.
with opelscanner i can acces gearbox an get torque and rpm readings out.

is there a way to get you reveal for me what mode in obd and what pid i should use to get those information out from obd?

[Artur]

You mean PIDs for gearbox?

[herraihme]

yes. mode and pids and possible bits and units.

[herraihme]

well is it possible get that info or not?

[Artur]

I do not have, sorry.

[herraihme]

well thats strage. how on earth did u managed opelscannercan show it if you dont know pids? as far as i know opelscanner talks only throuhg obd pids.

[Artur]

The PIDs, used by OpelScanner are different, then the ones, used for OBD.

[herraihme]

different pids? it should be impossible.... same units and sensors are physically in same locations in can... and answering same data to querys.... no mater what program you use?

[Artur]

Querys are different.

[herraihme]

yes thars could be but guery adress is same and recieved data as well.... so i actually need obd mode (quess it would be gm:s 22) and hex location for transmission and info how data is recived is there different query and several addresses for rpm and torque readings or will it be one guery and several byte answer whitsh containing several readings. if so it would be nice if could tell each bytes meaning.... calculations can figure out if just right binarys are available.

[herraihme]

Let me try again. Sorry english is not as good as it should to be.

id like to get torgue and rpm values out of at af at40-6 gearbox

so i suppose opelscanner connects to it straight through canbus and device is  $7E0 to $7E7? Or is opel using some tifferent address?
next you need some mode and pid request to get answer. I assume mode would be 22? but pids are total mysteri for me.

so can you provide proper canbus requests for me so i get it to work?

[Artur]

OpelScanner uses opel's protocol to get data from the ECU and it has different PIDs, then the OBD. I checked with the Tech2 - it does not show the parameters, you want.

[herraihme]

well perhaps my information ist correct but <2000 opels used to VPW protocol but newer use standard ISO 15765 CAN
am i wrong?

[Artur]

That one uses GMLAN CAN.

[herraihme]

i have found that gmlan is pretty much same as other can reguest. and i have gmlan capable device.
next is gmlan request:
Return to Normal message (0x20): 0x7E0 01 20 00 00 00 00 00 00

where 0x7E0 is ecu adress... so it seems to have exact same address as in normal can protocol... so if you can provide reguests and answers to gearbox rpm and torque i could figure it out. i think i can learn gmlan as i did rest of protocols
