Default The Evry mod how to.

I can't believe there isn't more clear information on this, i spent about an hour searching and ended up doing it the logical way to me (knowing basic electronics).

The mod really is simple, hopefully this clears up any confusion from the many other threads because i was indeed confused with them until i thought for a while on it.

This shows exactly where the injector harness is and what part of the wires to splice (though either side of the plug will work, this side is more accessible). Wires 2 and 3 are connected with a 1k (what i used) resistor. Wire 2 is the first pin on one side of the harness, pin 3 is second from the other side. The wires are labeled on the harness (which is awesome).




Here's the wiring, i personally cut the wires, put the resistor wiring in there and twisted it all back together and electrical taped it up. Basically you take the wires apart, splice them back together, but add the resistor's wiring.



For "tuning". You turn the resistance down until the motor starts idling rough, then turn it back up until it smooths. I played it safe and went to smooth and turned a bit more.

And the disclaimer part, you **** up your car, not me, i'm not liable for damages.

Any questions will be happily answered.

I'm not sure the engine code, works on the 1.9 TDIs from 1998 to 2005 (correct me if i'm wrong, i'm very new to diesels). It tricks the computer in to dumping more fuel in (which on a diesel is like pushing the pedal through the floor). Results surprised the hell out of me...but i also have bigger injectors.

As I understand it:

There's a sensor that senses the position of the quantity adjuster. Think of it as a syringe pumping up and down. If you extrapolate for time, you get a (more or less) sine wave.

The computer reads this wave to check itself on how much fuel to inject. What you are doing with this mod is tying the signal low through a resistor. The lower the resistor, the more of the voltage (and thus amplitude) of the wave 'leaks' out.

A shorter wave is interpreted by the computer as a need to move that syringe plunger further, resulting in more fuel.

Honestly, it's a lot more fun with a switch and potentiometer in cockpit somewhere . It's telling to witness the change when the switch is flipped.
Watch out for the smoke, though. Mine absolutely dumps the stuff.

Yeah, i put mine on a switch, thing smoked everywhere and i got horrible fuel mileage. It's fun to flip the switch on while you're flooring it to feel the actual gains.

If you don't under stand the information given in this thread...

Don't do it. I created a circuit that indicates if it's on. I built it, tested it and tossed it. Walk away.

Everytime you post a picture with PhotoBucket, a TDI gets below 30MPG.

Explain?

And BTW, by resistor i meant a potentiometer so you can dial it around until you find the sweet spot.

Its a crappy and ineffective mod that could potentially damage your engine.

well i would not say ineffective but you need more air. my GF car i run the evrymod over a 500ohm and a 1k pot. i got R520 injectors, a KKK K14 running 22PSI and 4GPH meth injection. I'm still tweaking the car but i got no chip. i will run the dyno in few weeks

if you do this to a switch just for some smoke action do you need the resistor? 99 bug TDI 5spd

Yes, the resistor is required. I don't know what would happen without it, but i'm sure it wouldn't be good.

I think the reason nobody fully explains this is because if you can't figure out how to do it with the limited info you probably won't understand the risk your taking when using this mod.

I did this mod awhile back, only use it when I see a big pickup or some asshat is riding my bumper.
