Audi AAN with auditrigger, no signal

[magloman]

Hi good people,

Just gonna start by saying that car runned fine with original ECU Before installing VEMS. I have just swapped ECU nothing else done with Engine.

I have just installed a Vems v3.3 in my car with Econoseal and made an adapter Cable to motronic55 as for now. I will make a new harness later on after Everything is working and maybe Another Engine.

I have never got this to work. I have switched to latest firmware and not sure of settings and such things.

When trying to make triggerlog it sees nothing! It is not a gray screen, nothing like other triggers-Pictures I have seen. Can it be someting with my computer or setup?

When cranking the rpm is 0.

I connected an oscilloscope on the Three different trigger pins and at least something is happening.

I have my primary trigger input from G28 crank VR(T55-49) on EC36-27
G4 reference(T55-47) on EC18-12 and have switched pin 1 and 2 out in Engine compartment
secondary trigger G40(T55-8) at EC36-13

+5v is taken from EC36-29 Motronic55-12(this is a common +5v for all sensors)
Is this ok, how is connected on PnP? Is the EC36-29 and EC36-28 internally connected?

I have measured that the hall sender has +5v on its pin-1 and ground on 3 then about +4v on pin2 when still.

I have a Picture for the oscilliscope on the rpm signal, is it suppose to be this low voltage?

Some report i tried yesterday:

/edit: I have not followed the grounding guidelines, how is that even possible when making an adapter? How is the pnp setup?
I have just connected all grounds from the vems and motronic harness into single joint.

Can this be the cause?

was you ecu ordered with audi trigger option? or it was generic one? anyway try to test some p259 outputs are they working? :)

Hi,

Thanks for your reply  :) Its much appreciated!

Yes it was ordered to work with stock/OEM triggers, I believe the word they use for that is "auditrigger"

I just got in from garage now, I did use a separate microphone cable and was extra careful with it. Now I have at least primary trigger working!  ;D ;D
I will fixe same setup tomorrow maybe and se if secondary shows up, buts thats special. I have a Hall sender on camshaft and VR as reference. I suppose the reference must work for the hall-trigger to get useful?

I will post back here with update.

if you put hall sensor signal to the ground then you can test reference signal :)

OK, will look into that,  know I read about that trick. It feels like I have read about averything there is soon about this topic, haha :D

Today I have made a Cable for the second VR crank home trigger. Now I have two trigger signals in the triggerlog! Yes! :-)

Now I have to check wheter my settings is correct for this. Tried start the Engine but it will not start.
Now I see the rpm when cranking at least, its about 200
