Can you flex fuel this Camaro to go between pump gas and E85 with a PCM or ECM computer adjustment and something to do with pulling pins on the ECM or PCM. I was told you can go E85 on this year Camaro ,but making them flex fuel friendly with the GM flex fuel sensor is not going to happen.

Change over the whole fuel system for more flow and tune the ECU I don't see why it couldn't be done. Not sure about the gasket material in the ls1 though.

I am doing it with my 2002 Camaro this week. Will post results. Have to get bigger injectors and a e85 fuel pump.

I believe there is a PCM out of a express van you can use that has the flex fuel tables already programmed. You could run a flex sensor with that pcm and switch back and fourth on the fly.

I was going to get a GM flex fuel sensor but was told that it might not work with my pcm? I keep search thread about flex fuel and some of things guys mention about flex fuel is (pulling pins?) on your pcm, or using unused pins on the pcm to have some type of flex fuel ready pcm .Then guys post up comment about rewiring the pcm with taking one wire and put in another wire slot and you can have flex fuel capability.

New file will have to be flashed and be re tuned but yes you can use the stock pcm in the car. Stock fuel lines don't have to be changed (I know form experience i was able to trap 144 mph on stock feed on e85). Pump will have to changed i say a single 340, as i seen a 450 push past the stock regulator. I use a stock gm Continental e85 sensor.

I got the C5 fuel filter/regulator kit plus the Walbro 450 fuel pump kit all in hand.

you can try it but don't be surprised if it still pushes past it

I'm also running a Walbro 450 in the tank and was told that I would have to scrap the C5 filter/regulator if I wanted to run E85 or wire in my secondary pump for NOS. I should have just kept the factory fuel filter set up, capped off the return on the block in the line and ran an aftermarket adjustable fuel pressure regulator and ran a new return line to the tank.
