Ecu testing

Yes I have for every ECU and MAP sensor except 0 280 100 001. But I promised not to hand over. For MAP sensors Bosch reference is only an indirect measuring method via ECU. That is why I prefer my own references and only consult Bosch reference when I am in doubt with my own reference. That happens if I did not have enough or questionable sources. And also Bosch references clearly demand that you have to set type 2 and type 3 MAP sensors in defined surroudning pressure. For type 3 even in 2 different pressures to verify altitude compensation.

Ok, strange that Bosch keep on informasion like this now over 50 years later, will think they was happy that people want to keep this old fuel injection in working condition and not trow it and change to å New and much cheaper aftermarked fuel injection system that easy do what you want.

And it is a stupid quistion to ask you if you can check and calibrate a 0280100015 map and a 0280001009 ECU after Bosch spesific correct value, so I know that I have the correct map and ecu for my car?

Can you tell me what the spesific surroundig pressure for calibrating is? Is it 1013,25mbar?

Hi,

Bosch still officially calibrate and repair both ECU and MAP sensor. Just contact your local Bosch service and they will help you.

Hi,
Today I have do some new test on my ecu test stand with a new instrument for messure openingtime on injector, with the new instrument the strange error messurement is away and I get new value that looks more normal for me without have any referance value from bosch on what is normal.

Have take the same test on 2 different 0 280 001 009 ecu with the same ohm value on air and coolingwater temprature (300ohm coolingwater temp and 391ohm air temp) and with the same map 0 280 100 015 that is orginal and not open. the ms opening time is almost exact on both ecu with in max +-0,1ms in differance betwin this 2 ecu on the same rpm and inlet pressure on every rpm vs inlet pressure i have checked, so I think I can use this as a referance to check the ecu that I have in my car, but I think you Volker have right that the ecu that I have in the car is also OK, time will show. but anyway good to know that the ecu is ok and happy that the error value is gone
