E85R PID - Not working for E37

[engimuneer]

I'm attempting to determine what the ECM thinks the ethanol percentage is and have E85R enabled as a PID. After reflashing the FlashScan, neither that nor the 'Fuel Type' PID show up. Is this only compatible with E67/E38? What would it take to work with an E37?

Thanks

Have you tried GM.E85PCT? Have you validated the PIDs for that controller? (V7.5 Scan tool, Info->Validate PIDs)

Thank you for the help

Once I validated the PIDs with V7.5 Scan it would allow me to DAQ SAE.E85R. Still couldn't get it to work with the BBX and writing to the Options.txt though.

I can't find GM.E85PCT after several read throughs. Will try again tomorrow.

Unfortunately, the results I'm getting are quite funky. Started off at 75%, which was ok for the previous fuel tested on that tune. Did the appropriate refill procedure (>3 gallons, drive more than 10 miles) and it only dropped down to 48% content, when I know it's 10%. Just another piece of the puzzle.
