I am told only one person has found it and that is lsxworks. I'm sure someone has to know. Trying to do a Flex Sensor integration on a 2009 CTS-V. I can not find anyone that has done this on a e67 PCM for a ctsv yet.
Yes I know you can do a 12v single to do the e85 but this integration would create multi maps based on the %.
To sum it up just like haltech's setup
