    running a SBEC2 ECU on a 90/91 SBEC wired car

    As we all know, a SBEC2 is very different than an SBEC and you cannot simple plug it in. I have found and tested a solution simply place a jumper between pin#8 and pin #57 either in your harness or on the back of the SBEC2. Ma Mopar moved the ASD sense line from pin#8 on the SBEC to pin#57 of the SBEC2. I check my bare PCB boards to ensure both boards are happy with the change and we are good

    My FWD stage 4 worked great (SBEC2-652) next to try my 92 SBEC2-377..The numbers after the SBEC2 identify the last three digits of the PCB part number.
    Brian C. this is in support of converting a SBEC2 V6 to Turbo.

    Excellent. This will keep me in stock electronics for a long, long time if it is that simple. Thank you for all the work on this.

    Other ideas would be to either
    1)switch to high Z injectors and reset the error bits of the tune
    2)use an inline 10 Ohm power resistor. This will change the latency of the injector so a retune is necessary
