Alcohol % PID

Hi, i am swapping my truck over to flex fuel, and i noticed i didnt have any alcohol % pids, is it hiding, or does a custom one need to be made? thanks!

Try deleting your vehicle from the scanner and re-polling once you have enabled FF.

You compare the commanded A/F to what is in the Fuel>General>Stoich A/F table. Should have a table that looks like this on a FF OS.

there are no flex-fuel tables in that old pcm... in a newer flex fuel vehicle with newer ecm's, there are separate tables specifically for e85.. separate timing tables, afr tables, etc... which are not available in that old pcm on that old truck.. and no, there would be no alcohol % pid's in that either, since it was never made for flexfuel/e85, so it never had any sensors for it.. so no parameter to log for it...

There is only one for that OS. In HP Tuners the alcohol PID is located under Fuel System > Alcohol Percent. There isn't a fuel temperature PID available for that vehicle that I'm aware of.

If you can't see it, you may have to use the "Clear Last Used Vehicle" button and reconnect.
