Ha! this reminds me of the time after my swap, car would not turn over, cause I mistakingly thought the Windshield washer relay was the EKP module DOH!

Still need to stop by :)

fuel pump relay = EKP. :p

Oops pre cat and fuel pump relay(black)

[nando]

you don't need the post cat O2 sensors at all.

Don't forget the o2 sensors(post cat) if that wasn't coverd yet

Any idea if the E28 fan will work with a PWM controller?

Most likely would. Only potential issue I can see is the fan drawing more current than the controller can handle.

Last two pictures & text at http://www.r3vlimited.com/board/show...1&postcount=15 describe how you can use the aux fan controller. I'd definitely recommend it, PWM fan is much nicer than something that cycles off & on.

Thanks. That explains why I couldn't find it separately. Appreciate your help.

Its part of the fan, but you can cut it off and use it with any aftermarket fan.

Thanks @nando.

Still can't figure out where the fan controller is mounted. Can you point me at it? Sorry if it's obvious...

[nando]

it's mounted to the frame rail near the engine bay. There's a whole bracket/shield that goes with it. may as well take as many of the fuel lines as you can too!

the EKP just runs the pump. So you hook up the DME to the EKP, and the EKP tells the pump to run (and also how much fuel to pump).

5 bar fpr. The EKP and fan controller would be good too.

Thanks.

Where's the FPR mounted on the E46/M3?

Same question for the fan controller. I can't find it on RealOEM.

I'm already planning a single in-tank 255lph fuel pump. not sure how an EKP will fit an E28?
