Trigger problems on Audi AAN

[Durr McDanks]

I am a new to using standalone systems so forgive me, but I have two problems. The motor is a Audi AAN (2.2L 20vt).

Problem 1. I am receiving a less primary trigger error. Here is a trigger log, but I am not quite sure on how to read or what to make of it.


Problem 2. I have a problem regarding my MAT sensor readings. I downloaded the patches for the CLT and MAT sensors. The patch for the CLT worked great but every time I download the "audi plug and play" patch my MAT reads -40 C.  Also, I tried downloading the 1.8t style patch and it sends the MAT reading to 64 C. I am not really sure what to make of this.

Any help is much appreciated. Thanks in advance.

have you tried firmware patch upload?

and for good trigger log try to remove spark plugs, disconnect injectors and crank engine for about 10s, just check that laptop doesn't disconnects from ecu while cranking. you should get trigger log like this

Ok, I will get a better trigger log. I tried the Audi plug and play patch and the 1.8t patch. By the way these are the primary trigger settings I am using: http://www.vemssupport.com/forum/index.php?topic=1695.0

use 1.2.2 firmware, and use these trigger settings

Here is a trigger log with your settings:

How do you have only 10 teeth? Also I entered in for the trigger reference tooth table 0,8,6,4,2 but I am not sure that's right.

[Kamuto]

that's a 3 possible ways to start it, div by 3 =90 tooth div by 9 =30 tooth and div by 27 =10 tooth, your trigger log isn't perfect, but I think you can try to start yours car  ;) just make sure you have good battery. try to crank it and will see how it works.

Unfortunately, it did not turn over. I am getting fuel and its sparking, but it's still saying primary trigger error. Here is a picture of my coil outputs and fueling table.

[Kamuto]

sometimes you can ignore that error when cranking at low rpm, don't know how your spark outputs are wired. but if you got fuel and got spark, if you have correct spark order, it should start

try to use these settings, that were firing order on my friends p&p vems for aan

[Durr McDanks]

Alright, something must be out of order, but I thought the AAN fired 1,2,4,5,3 or at least that is how I have it for both the ignition and fueling orders.  Also, you may be right about being able to ignore that primary trigger error because it only pops up at the very end of a cranking cycle and for a very short period, but I still have secondary trigger errors as well so that may be a problem. What's the firing order of that ignition output table you posted?
-Thanks for all the help so far

Hi

Upload a real .vemslog and triggerlogg while trying to start.
A log tells more than a thousand words ;)

these Ign Output Table is factory setup for a Vems PNP AAN Setup.

Is your Vems a PNP Box?

Unfortunately, I went the cheaper route and decided not to do a PNP VEMS.

Reply number #5 is the trigger log with those settings
