  • Bosch Injectors High Impedance

    My old Bosch (280 150 842) injectors packed it in. The replacement (280 158 827) are now high impedance, will my ECU recognize and function normally, or will this req a program update. Ecofuel conversion Impala.

            It's a 06 Impala with Ecofuel conversion. Injector sit six abreast in a fuel rail which makes replacement simple. I managed to buy five injectors local, which leaves me short one. Has anyone used Standard automotive FJ 1131 with any luck, tech dept said it is a update for the old style Bosch low impd inj.

                So what does Ecofuel have to say about compatability ? http://www.ecofuel.com/ConversionDetails.aspx?id=189

                  You can go from low to high impd inj, but not high to low without a resistor pack. The new Bosch also might req more pressure or increased pulse width, increased pressure will be a problem with systems with pressure sensor on the inj rail.
