Since the engine driver sees more RPM than it should mean that somewhere it does not connect hall pin2 - ECU either on GND power supply or + so I would look at power supply that would explain 17V

Do you have any vag? then you would give the group log 000

You were right, PWM doesent afect on RPM reading.
To short story, problem was in relay 30. When i discconect relay I get 17V on hall. Wrong RPM reading was also beacuse bad relay.

Yes I have VAG-COM i was reading RPM on it.

I leave ABT distributor on car, and after relay 30 repair engine works perfectly( I don't know why ABK distibutor have bigger windows on metal sheet? )

Thank you all for your help and time

What is normal ignition angle on idle when engine is warm? I read somewere that it needs to be 6° before TDC at 2000 RPM, but when I set it on that values it doesen't work like it scholud.
It is more like 20-22° on 2000 rpm where engine works best

6° above 2000 rpm. But that's not all, the engine driver must be locked and of course warmed up above 80stC. Zero errors

Read in the forum about blocking ABK up to 92r with sensor above VAG

And I'm sorry for the spelling I write through Google translate

Thank you I will try that

My engine is from 1994 year with automatic gearbox. Siemens ECU, 43 pin

It's in a nutshell because car 94r.

Engine warmed up above 80 degrees Celsius, no errors in the engine. You enter vag basic settings group "000", the engine will go into low speed, it may even go out (500-600RPM). When it enters this mode, set the lamp to 6st, the second person keeps the speed at a level above 2000RPM and you set the ignition (of course, "0" cuts in the window) ..

You will know a blocked engine by the fact that the RPM will drop and "0" will not move (it will be stable).

Thank you very much
