The attachment VZ SV6 Logs.zip is no longer available

Brilliant!


Postman pat rocked up today with a lovely present... heres the CAN prototype. Fits perfect on an arduino pro mini. If all goes well, should be able to completely eliminate the need for 3 ELM cables and no more buffer full!! This should be more applicable/appropriate for when logging VE stuff.. Since I know things tend to go pretty quick there!

From what I can tell, the VE V6's also use CAN 11bit 500kb/s. I think. Alot of standrd requests as seen from the VZ controller are performed. I think there is a 11bit 250kb/s request that is made at the beginning. Bit then I get an error as its not fro a VE v6.

Also not sure if anything special is occuring over CAN29bit (I didnt see anything), but they quite possible be communication over GMLAN as well.

I noticed I had a couple inconsistencies from my previous logs, Fixed those up and double checked the reoccuring PIDs in this menu to confirm what is what.

3/12 done.

From Fuel Trim menu.. almost all of the parameters are completed even before Iv started reversing! Looks like its only DPID 8,9 and A that I have to work on.

Any other PIDs are unknown, nothing changed in the tech2 menu at all.. weird there is a whole DPID frame that literally didnt get used.

4/12..

pcb looks good

ok so heres a few more I have, few supercharged ve maloo logs, also a ve v8 manual

maloo logs.zip

And from the Instrument Menu. I think this will be the last set of logs, since literally almost every other table utilizes all of these PIDs found already except maybe 1 or 2. Will continue on with getting this engine data stuff fully functional now since I now have PID sizes,units, min/max values ect.

A bit more clean..

Im thinking just have a bunch of tabs that can have different gauges added to them. Ill also make it so the gauges created remain on next startup. And different protocols/cars can have different setups.

Not quite sure how Ill add in this data recorder.. will have to find a format thats easy to use, But itll be a bit difficult to replay.. as if the user doesnt have all the gauges used previously, then some of the data will not be displayed. I guess a simple textbox can be programmically created for each parameter which doesnt have a gauge developed.
