That is awesome, I could definitely use help and guidance. I read about open inverter and zombie VCU. I decided for now that I have a lot to learn and zombie VCU seems more full featured for entire vehicle control so I went only with openinverter mini mainboard, got it on order. I'll dig into how ...

I thought that was the situation, that is needs to be accomplished/figure out. Thank you.

Everyone I apologize. I was offline a couple months with health issues and when I came back I could not get logged into the forum. Thanks to Paul Mangelsdorf for helping me figure it out. Apparently I was not around for the instructions to log in after the forum updates.

Just a quick catch up is ...

I was able to load the generated global a dbc in cabana last night and it decodes several messages. I still only have ECM and VICM(HPCM2) on the bus. Not as many messages decoded as I hoped, the life of reverse engineering.

Started looking around for DBC definitions to decode GM Lan and found something crazy, I suspect other people here are already working with this.

Definitely good idea to snoop the GMLAN networks. I printed and highlighted the network diagram from the 2017 manual to help me get familiar. I did a bit of work this weekend, I'll write up some more detail this week.

Def appreciate any cheering. Small update:

Ordered the HpTuners MPVI3 to see what it will dump. I want it for my other ICE projects but maybe it will dump something sort of useful, maybe not.

Did a deeper dive on Kess V3, ECM Titanium, WinOLS and several other similar things for binary dumping ...

Excellent, I was hoping you would reply. I definitely appreciate the offer to help. I did find the 2017 service manual and have been getting familiar with the schematics and connector end views. Not sure how much I can help but let's find out. I'm having a bit of paralysis because I have 3 major ...

Hello, first post but this looks like the right place to be.

Some Background on this long and winding road to the Chevy forum on Openinverter.org:
11 years ago I wanted to build an EV conversion so I studied up for several months, purchased an RX8 and the canEV adapter plate. I made my full plan ...
