Hi, I need to make immo off on Audi 100 2.3 benzine year 95. The car have a JEtronic KE 3.2 inyection.
I take out the immo box and open it. Inside have a 93c46 eeprom.
Inside the ECU motor I don?t saw any 8 legs eeprom, all components are pth, don?t have smd technology. One component is printed "S+B9106 B57120"

The car have many problems to start, many times don?t star and immo symbol blinks on dash.

Atached 93c46 of immo box, I know that pin is 4755, but I need make immo off.

27c512 where? in ECU engine? The engine start whitout ECU Jetronic that I upload photo. Don?t runs properly but start, I don?t understand this.
Whitout immobox don?t run, doesn?t rotate the start motor.
Inside the Jetronic ECU I see a chip similar to 27c256 that has printed "S+B9106 B57120", but I don?t know if this chip is a 27c256 eeprom.

Use an emulator and connect it to the immobox plug. In the scheme of your link, You must connect:

12v emu to pin 12 immobox
GND emu to pin 11 immobox
K-line emu to pins 9 and 10 immobox (you must short this two pin because the line of diagnostics go across the immobox and if you donīt short them, you donīt have communication with engine ecu)
And you must disconnect immobox, ofcourse.
