Planned ECU mods

Want to add

  • The VW J293 from a Mk5 Golf is known good.
  • But when mounting to a BMW why not use a Temic PWM controlled fan from for instance a e46 m54 engine?
  • Unfortunately I don't believe I have the space with the 3 row Z3M rad between the water pump.

Is it possible to configure 3rd trigger to use as freq. input for Ethanol content sensor instead of tying up wheel speed inputs?
