[Diy_efi] Audi CSI with ECM update?

Simon,

I have not used one, but there are plenty of people who have.  Other
than the sensor that is built onto the circuit board, I don't think it
requires many.

There are people selling assembled Megasguirts for $500, but I believe
you can build you own for half that.

Good luck,
Bobby
