Hallo, i was amazed as i saw today that there is a PNP Motronic VEMS.

The question is now how PNP is it and what must i change.

I am not very electronically inclined so my questions are dumb:

I plug the VEMS PNP-Motronic to the harness, istall and connect and verify and calibrate the Wide band and the EGT. Is the car now ready for the Tune?

The VEMS comes out of the box with support for the Ignition, injection and Boost control without further mod to the Sensors or the cables of the Car?

Is it possible to find for starters a full runing program for the ADU engine, and from that point modify it further?

Hi, i am thinking of Using the VEMS v3.x on my currently Stock Audi RS2. It has from the Factory an I5 2.2. liter Turbocharged engine (Engine Code-ADU). The stock ECU system is a Bosch Motronic. For the future i am preparing a strong bottom end and big turbo.

The car is an everyday car and want it to have a cultivated ride (when i am cruising with it or in the City). I want the Climate Control (Air Condition), Auto Check (it has also Trip Computer but i think it will not work with the VEMS).

I would like to make the convertion this way so i must only change the less possible stuff to run on Vems (and also easy to go back to the Motronic system if the car will be sold).


I connected VEMS and tried to connect it to the PC.

The connection is Succesful but i become a Message that the tabes between controller and MT doesnt match.

I Choose 16X14 and it says the Controller has 12x12. I made a FirmwareUpdate to 16x14 but i still become the same message.

If you have pinout for ADU, we can check if the cyl1 <=> 3 ignition is swapped, so we can hint h[2]= ... change if necessary.


MAT sensor

With bad table chosen at firmware upgrade, the MAT reading will be almost constant, and if it changes at all, it decrease with rising MAT.


2..3.2008

It started with Marcels file. Very nice. Still no EGT and WB installed. Very happy!!!


4.3.2008

I installed the cables for the Lambda and EGT. The 12V connection for the WB comes not through VEMS but separate doesnt it?

I would also like to know about the WBO2 Calibration Constant. Should i measure it or is it mesured from the factory?

The sensor must be I free air and you should see the number near 20,9 in the lcd display if not you can adjust the Calibration Constant in Megatune.

Thanks


Done some more today. I am seeing the target

AFR at idle but not everywhere else. I also made a Log.

Here is some throttle while standing and the other one my first log while driving. Also the MT File i done it (Question here: What value for EGT Calibration in MT?)
