The VATS is really a non issue here... the system is working fine. The ecm is what shit its self. It is most certainly NOT plug and play either.
I do appear to be dealing with 2 separate problems tho, one being a wire (Comms to ECM) issue on top of the original corroded ECM.
Get a replacement and send it off and have the VATS deleted. . . although from what I know about the VATS system the ECM should be plug and play if it has a BCM. The signal from the BCM to the ECM to enable fuel continue is a 30hz or 50hz wave, it's not based on the vats resistor value. The BCM or VATS module authenticates the resistor and if it likes it, it sends that signal to the ECM.
Lots of tuning services offer VATS delete within the ECM for LT1 cars:
Based off of this
There are 2 square 28f512 devices labeled FLASH that I think MAY contain the info.... Option 2 is I order an OBD1 Flash tool for these. But most look like I need to be able to pull the info off the original via the diagnostic port..Which cannnot happen as it has 0 comms
It is, but this is the ECM not the BCM/CCM. From my understanding this gets signal from the VATS and controls ignition/fuel etc.... The VATS part is working great on this one actually. Car starts and stalls in 1-2 seconds with canbus codes
