I dont do a bunch of the older GM stuff, but I have a customers 2004 SSR Its got a Whipple on it along with a Larger DBW throttle body with an adapter harness for the DBW TB.
I upgraded the stock 12587603 OS to a 3bar but in VCM Scanner I only have a very small amount of PIDs i can datalog with. In this case should I try and find another OS to flash to the ECU? This OS seems to be good as far as having flex fuel and the ability to go to 3bar but I just cant log anything with it.
What is not logging?
Doing the OS upgrade will not take away anything that you could log before hand. Always re-poll for supported parameters too.

If you don't post your tune and logs when you have questions you aren't helping yourself.
Only have about 20 pids. Nothing related to me being able to datalog and tune VE tables at all.
Honestly probably get away with being on stock OS...

Weird. I guess I don't click what the PCM shows but just all channels instead.
Does that computer offer a 2 bar upgrade? Maybe try that.
