Trigger problems on Audi AAN

[Kamuto]

just write from which output which coil are wired.

I tired cranking it more today and its seems really close to turning over but something is just not working. I think my secondary trigger settings may be wrong.
Here is my wiring set up and one more triggerlog (order is firing first to last):
Ignition:
G/W   EC18-11   Stepper-D   Power output stage for ignition, cylinder #1
V/BK   EC18-05   Stepper-C   Power output stage for ignition, cylinder #2
BK/Y   EC18-10   Stepper-B   Power output stage for ignition, cylinder #4
BK/   EC18-04   Stepper-A   Power output stage for ignition, cylinder #5
BK/GY EC36-11   Ignch4   Power output stage for ignition, cylinder #3 (its bridged to the stepper drive thanks to Marc Swanson)

AAN ECU pins corresponding to firing order: 1,2,20,21,23

Fueling:
 W/V   EC36-20   INJ-D   Fuel injector #1 control (switched 0V)
W/BR EC36-08   INJ-C   Fuel injector #2 control (switched 0V)
Y/G   EC36-19   INJ-B   Fuel injector #4 control (switched 0V)
W/BL   EC36-07   INJ-A   Fuel injector #5 control (switched 0V)
Y/BL   EC36-09   INJ-E   Fuel injector #3 control (switched 0V)

AAN ECU pins corresponding to firing order: 36, 17, 35, 16, 34

spark outputs are correct in my picture, it suits your wiring. what looks spark plugs after cranking? wet or dry? and upload real config file.

Here is some friendly advice and questions :

What what trigger input configuration was your ECU ordered? Does it use all three stock sensors?
I have no idea what "bridged to stepper driver" means, what did Marc Swanson do? All the stepper outputs you listed are not used as power outputs, they are logic outputs to drive active coils or the stock Bosch ignition modules. That means the ignition output 4 has been converted to a logic output, and has nothing to do with "stepper output bridging" - whatever that means.

As Erik said, post a real vemslog (and triggerlog), not just pictures and words. There is a "submit error report" function built-in to VemsTune that does exactly what you need, see Help menu.

Use a strobe light, and never ever give power to the injectors when you are not sure the engine is not firing the ignition right. It will only cause  problems. Fouled plugs and gas in the sump are not what you need.

Here is a report link to my trigger log: http://vems.hu/vemstune/bugreports/reports.php?cmd=view&key=j6in0N
I will get a vemslog soon of the secondary trigger.

Marc Swanson: "since you are using the stepper for ignition that means you need TTL drive for the coil. your ecu would need to be configured so that channel 4 is bridged for TTL drive. they dont always do that by default."

for start, use 1.2.2 fw not 1.2.6 1.2.2 were special made for auditrigger system. second, how your triger inputs are wired?

[Durr McDanks]

AAN   Color            VEMS        Sensor       
49   GY/GY   EC36-27   Prim. Trigger   Engine speed sensor 135 cranktooth   D
8   GY/R        EC36-13   Sec. Trigger   Hall effect sensor (signal wire from G40 pin #2)

and where is connected aan 47 pin?

[Durr McDanks]

I don't have the crank shaft position sensor hooked up. Does that make a huge difference? I will hook it up.

[Erikk]

Yes. You use it as camsync, and use the hallsensor on the cam to mask it every-other revolution. That way you get a solid camsync. Your way is not OK.

If you switch to VAG 60-2  primary trigger, then you can use the hallsender as camsync.

[Durr McDanks]

Question: In order to use Audi's 3 sensor style trigger I would need this to get the crank sensor dialed in?

Yes and no, you need a third trigger input if you have the stock Audi trigger. If the ECU was not ordered with one then you need to get that fixed.

Or better yet, get the 60-2 crank trigger instead which alleviates the need for the "third trigger" to let the cam sync mask out the single flywheel pin, and I assume ECU is already set up to handle a VR primary and Hall secondary trigger input.

Ok, back to business after a little hiatus. I have a third channel for triggering (pin 12 of EC-18) so I wired in the crank position sensor. Here is the weird thing, I received not one trigger error, but read no rpm with CPS plugged in.  Unplugging the CPS, I then received trigger errors, but read an rpm. Any thoughts? I might just make my life easier and switch to the 60-2.

cps cam or crank sensor?
