what is this? IP

[BEEJERS]

i am putting a real IP on my eco diesel along with a real turbo. i have this IP with the LDA that i am going to put on but dont know what i am suppose to hook the wire from this to.

HELP

[gnavs]

electric cold start, i think?

[BEEJERS]

it has the mecanical thing on the other side though???

[BEEJERS]

I'm a retard :lol:  :lol:  :lol:  or it retards the motor when it is warm?
also, what should it hook to?

Ya from what I remember if you leave it un plugged it will leave the timing retarted, apply 12v to it and back to normal.

On some AAZ engine, it have this device, the 12volt is aplied at 2800RPM and up.

12Volt on this device = more timing advance at low and med load on throttle, at full throttle 12V or not, that change nothing.

Not need for connected and the pump run normally.

At 0 volt  the fuel come from the governor shaft, it pass in the tube, like as you said, and bleed some pressure inside the pump, but, on the front of the timing piston it have a hole wich return on the aspiration side of the feed pump, that does not affect the operation of the timing piston.

At 12volt, the fuel do not pass in the tube, what allows a higher pressure in the pump, therefore it have more timing.

12volt or full throttle = the same result, at full throttle the governoe shaft is blocked and the fuel do not pass in the tube.

On the pump without this device, it have a hole directly under the governor shaft which bleed internal pressure towards the aspiration side of the feed pump.

On  AAZ engine, when I plug the voltmeter on the device wire,  12 volt is applied when the RPM arrive at 2800.

Another test,  when I put a ''ON/OFF'' switch on the device, and if I place the switch a ''ON'' 12V from the battery while I drive gently, I hears clearly the engine become noisier and slightly more powerful.
