DIYPNP Flex Fuel
Hello!
Im currently trying to solder flex fuel on my DIYPNP. I see there is already a wire coming out of the flex pin goin to the middle of the board (Under the Microsquirt Module). would it be OK for me to splice into that wire to solder it to the options port or would I need to cut that wire completely?
Thank you,

The FLEX input is already being used. Your profile says you have a 1994, so go here https://trubokitty.com/#/diypnpassembly and click 94-95. You'll find that 1V on the ECU pinout is the clutch switch, so your FLEX input is currently being used for launch control. As far as I know, the DIYPNP only has 2 inputs, and one is wired for launch control and the other AC. You'd have to give up one of those to have a flex fuel input, but someone correct me if I'm wrong. Also note that MS2 is only able to apply a scale factor to the fuel and spark map with regards to ethanol percentage, which is not enough to go from E0-E10 to E85 without a tune change. But it is useful when running E85 to run corrections since the actual ethanol content of E85 varies a bit.
