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
Worrying
I plan to break the engine in at 14psi so i might leave it there for awhile until i can source someone to build me a stock looking intake..
