Flex Fuel was only on one specific OS (12216125) for the 512K PCM. There was never any COS's written for that OS.

I asked a similar question in regards to a flexfuel COS.
It maybe possible just to use that OS with the Fuel Composition Sensor (pn 12570260).

I have the sensor & Ethanol Content Analyzer from Zeitronix hooked up for awhile now,Works pretty good.Instead of changing the tune all the time I would let the sensor do it,But I guess not.There is a OS with a FF tune I'm going to put in my 99 silverado and I'm going to put the FF sensor in that.I'll report back on how it works out..........Paul
No, it's specific to 5.3L trucks only.
