digi1 help?

[riceslayer]

i was just wondering of someone could tell me what the "co-pot" sensor does and where its located.

Also, i was wondering what the vacuum line looks like that goes into the digi1 ecu and where the other end of it was attached.

i apologize if these are noob questions but im currently doing a digi1 swap into my mk2 to run a boosted 16v and was told that these are two things i need.

if anyone could confirm this for me i would really appreciate it.. Thanks!

Run your hand along the backside of the throttle body. You'll feel the throttle adjustment screw and two vacuum hoses. One hose will go to your check valve next to the airbox, the other through the rain tray into the ECU.
The potentiometer is mounted in the boost tube going to the throttle body, and I'm sure the o-ring is bad.

is there any way to make digi1 work with a scirocco TB? it has the adjustment screw but only has one vacuum port.

incase youre wondering, im swapping digi1 into a mk2 with a boosted 16v and im just trying to tie up some loose ends.

You only need the one port for the ECU. The other is for emissions stuff (carbon canister).

Right, only the 1 meter hose is required.

thanks for all the help

does anyone know if it would be alright to use the other port to run to my BOV?

also would anyone have some sort of diagram for the fuse block or be able to tell me where these few go?


Color: orange/white, purple/black, blue/white

thanks!

There are a few loose single wires around the fuse box. I can only guess VW wired the cars for optional equipment for the dealer to install. You'll find the other end of the Bl/W and yellow wires zip tied to the harness around the oil cooler. If you want to install the cubby oil gauge, great news, it's already wired for it.

i found one loose wire coming out of the fusebox itself that matched up to one of these that isnt pictured so i get what your talking about.

but basically what youre saying is, i dont need these hooked up? this harness is getting hooked into a 16v with a turbo..not the g60 supercharged just to clarify

The CO pot adjusts the fuel either richer or leaner. A value of approx 500 ohms neither adds or subtracts from the fuel. Lower than 500 ohms adds more fuel and greater than 500 ohms makes it leaner.
