Hi,

Been on the look for voltage specs for these injectors and cannot find them anywhere. At one point I thought of using 750cc values @4bar but I don’t want to guess...

Any of you have data for these? OEM number 0280158209

Thanks.

Hi, thanks for trying to help out. I need dead times for 16v, 14v, 10v, 8v, and 6v if I remember correctly. I could use voltages from a 750cc @ 4 bar but it would still not be the same.

Nice! You mean 670cc versions with long nose and 7-holes? I will be trying 750cc values @ 4 bar. Then I will test your values.

THANKS! I am very thankful man I was willing to pay money for this... Nice that bosch informed you. I could not contact them. You have helped me a LOT now I don't have to guess KRKTE Values and TVUB either.

Hope you have a great day my friend. If you need help with anything just pm me. +1
