Which did you do, running both DME and G4 or ditched DME and running G4 alone?
And how many wires do you have to connect for 400+ft like you mentioned??!!
Thanks in advanced!
I'm going full standalone only keeping the stock DME for non-engine functions (and TC , if it works that is..)

The 400 feet of wiring consists of :

4 wires to each COP (6ft*4*6)
2 wires to each injector(4ft*4*6)
3 wires to ICV (3ft*3)
2 wires to each vanos solenoid (5ft*2*2)
3 wires to each vanos sensor (5ft*3*2)
3 wires to TPS (3ft*3)
(the stock M52 TB has 4, i'm borrowing one)
3 wires to map (4ft*3)

And some others to CPS, Cluster , anti-lag switch , speedo , etc

I'm building the exhaust without a cu tout atm , but plan on adding one that will be activated when antilag is turned on to save my cats life
