pmw fan controllers

[parsonsj]

How do you integrate the C6 fan controllers with the E67 ECU? I don't have A/C, so I would think this makes it easier.

It's pretty simple, really. Just add the pwm wire (J3-54, iirc) to the ECM, snag a C6 fan controller ($89 on Amazon), do some basic wiring, and have your E67 switched to PWM fan control (instead of discrete). Most tuners can do this. The guy who can set you up with a kit is Bill at BP Automotive.
