After going through some files for BLK02WS6 I believe that I have found the B9021 parameter for the 12592618 group of operating systems. However I need someone with this OS willing to test it out.
To test it, a log needs to be taken at idle of IBPW1 or 2 to give us a usable value. Then this value is placed into B9021 with all other injector offsets zeroed out. Then just log idle again, ensuring the scanned values match the B9021 value.
I do not want to post the cax until proven. So if anyone who is willing to test it can pm me there email address, I will send it through.
Other operating systems are in the pipeline & will be done as time allows.
Also have one that needs testing for 12587603 based OS's.
