I currently have a 383 lt-1 with a LTCC LS-1 coil pack conversion. Im switching to a ls1 ecu as well as adding a turbo and was interested in running e85 as a flex fuel. I plan on running it all the time but would like to be able to have the ability to switch back and forth in case I end up out of my area and have no access to E85. I just bought a 76mm turbo and need to completely replace my fuel system so I figure its a good time to hit it all at once. Im assuming ill need a flex fuel ecu and fuel sensor.

Has anyone else had luck with a system like this or am i asking for trouble?

 

I'm not really familiar with the flex-fuel PCMs, except that they require feedback from a few sensors that you probably don't have on your car. For my current build I purchased a dual-flash PCM. I plan to use that as my solution.

 

James I can work up a Flex tune for you with a 0411 PCM, but you will need the Flex Fuel Sensor.

 

Thanks, but it's just not practical with the 1/2 line and pump that I'm using. The sensor's Inlet/Outlet looks way too small.

 

I think I can turn off the flex. I was digging around on the jeep tune and it looks like it.

 

where did you get the dual flash pcm?

 

Frost sells them. I think he may be the only one. new dual flash pcms run 2 seperate tunes one pcm
BTW the search button can answer many questions

 

I have a friend that is assembling them for Dual-Flash currently. I can give you his contact info, but I have nothing to do with the sale of them.
