Trying to learn benching BOSCH EDC15C4 DDE 4 from LAND ROVER FREELANDER

[monstermurga]

Hi ! got a spare ECU for our freelander TD 4 just to learn & play a little bit, and with the pinout tried to connect to it on the bench.




I connected to Delphi Autocom and could read fault codes, so that was successfull.
I also connected to Galleto v54 and could read info and the flash file successfully.

But to go a step further, i want to be able to test injection on the bench, connecting a injector or a resistor with a led negative side on the injector output to watch the injection pulse.
(The purpose would be to learn to test if an ecu gives order to injectors correctly, so if in the future they brought me an ecu to test because x car doesnt start i could at least test that the ecu gives the order to the injectors)


I want to test as seen in this video :

Here im a little stuck /lost :

I think i should connect these inputs In order to simulate the car to start ( as if it was connected to the car )

Crankshaft Signal
Camshaft Signal the same as above.
I also connected the earth pins of CKP and CMP in the ecu to GND
I tried to send this 2 signals as a standard square waveform from the oscilloscope hantek 1008 through its generator (I couldnt customize it as the built in example reference CKP signal but had to try as they came by default..)

It doesnt do anything to the led i connected to the injector output.

I dont know if maybe I need this ecu to be immo off to start on the bench ?
I know the signals are not like the needed signals (Will try to record the signals from the car with the hantek software and then play them on the bench)

Maybe i also need at least the signal of the fuel pump? common rail pressure ? TPS?



I have the pins for the injectors also, but dont have at hand now to post it, i think it was 7 on the " 5" connector.

Any tips? Thanks
