    2000 Chevy Truck VSS Output setting killed ECU

    The VSS Output Pulses per mile has a Warning not to set to a low number or Zero but the consequences are not completely visible in the description. I wouldn't think 1,000 would be low number but apparently it is and it killed my ECU! Is there anything I can do to get it back or is it a brick now?

    Did you look at a stock number by any chance before entering that? I think my stock # was over 18,xxx. How are you sure it bricked your ecu?

    Yeah stock was 4000. I'm trying to get a t350 with 8kppm to work. But with the gears, I had to reduce it. I know because during validation, it didn't not cycle gauges and fuel pump. Then it would not start. Upon trying to scan or load a new tune, it does not even see the ecm. I did the same thing to 2 different computers. The second one was by accident because I didn't delete that file off my computer and I loaded it into the new computer.
