I bought a car from Poland, Audi Cabriolet 2.3E NG 1993, and I have a problem with idling

There is installed on your system from Digital ECU Ottomotive.pl

the problem is the high speed at idle for Engine Overhaul

The question is: how or what you regulates the engine idling?

Hi. Usually we do not connect idle control to our device. It is left as it was before EFI. I don't know what is your case. First of all check leakiness of intake manifold. Sometimes it happens that after mounting electronic injectors or doing changes in intake manifold regarding EFI conversion. Connect 12V light bulb instead of idle valve and check is it glowing or not and is intensity of it changing with RPM on idle.

Thank you probably solve the problem...

There is one problem, the car cold start well, the speed at idle as well.

When heated car will not start, probably too much fuel into the cylinder (rich mixture)

Picture 1 is beyond repair ... the original temperature sensors (that there were)



Picure 2 is a correction after the new temperature sensors (notebook is turned off so these values are in the off mode)



After disconnecting the sensor value does not change much (goes down to -19/-20 degrees)

Thank you for your willingness and response

And one more question

you have someone to ECU maps?
in the download section is 2.3E NG 10V but maps "boost" and "Ignition" There are not all

Please do not change everything in configuration because you will need to tune it one more time!
You are looking on Air/fuel ratio parameter but you probably do not have connected external wideband controller to DEC? Do you? DEC does not have internal controller, it only can use external one. Now you are looking on noise signal on analog input, which is not connected!
Keep focus on VE map, which is responsible for fuel amount. You don't use Boost or Ign maps, so live it as they are.
For engine start you tune Configuration->Engine start->Crank PW table. It tells what is injection pulse width during cranking and it is according to engine temperature. Please check is engine temperature is changing (Coolant temp parameter). If so, and if you think that amount of fuel is to high when engine is hot then you can change it.
If you do right click on the parameter display bar (above main maps) then you can change parameter do display. After changing something you need to press Permament button if you want to burn settings into DEC. You dont need to press send config or maps buttons after you change something. When you changing something it is send to DEC.

Thanks for your help, the problem was in the coolant temperature sensor. Now it is showing fair values. Do we put ECU Down river maps and configuration. It worked two months.

But at the moment, an additional problem. The car will not start. But sometimes it happens that normally starts and goes into the normal performance ...

Fuel pump hear how it works and gives a pressure of 3 bar

Here is the video when car is working normally



Here, when the car is not (started and immediately turn off)



thank you in advance for your help


UPDATE!!!

I noticed that the vacuum does not change (ENGINE MAP)

I watered the hose to the ECU and vacuum mouth, I did not at all value and also did not change.

It is possible that the ECU is defective?
