Flex Fuel
« on: August 03, 2023, 08:49:44 am »
Hi Guys, I've got an VEMS ECU running a home turbo charged Porsche 3.2 Carrera.  It's been built and tuned and runs well.  I'm preparing the car for a flex fuel (E85) set up and have modified the fuel system exhaust and intercooler and can't wait to get back to the dyno.

I'm hoping someone can assist with the physical side of getting the flex fuel set up.  The ethanol sensor is plumbed into the fuel system, the plug is pinned at the sensor and I've got signal, power and gound wires to the EC18 plug and have the correct female pins and seals.  I've been told the sensor ground goes to pin 17, but I need to establish where power is coming from, and lastly I need to get a wire from Wheel speed sensor 2 (which is on the board) to a free pin.  Can anyone assist in identifying where this is on the board?

I realise some of these questions may relate to the pinout used in this application but perhaps there is another Porsche PNP user out there that's done this before?

Many thanks.
