You need a proper bench flash setup with power, obdii, pcm connectors etc.
I assume you have all that?

= failure

You cant do that. You need the PCM connector with power to work the PCM.

Check out speartech. They do bench setups so you can work it out of the vehicle.

No prob. You wouldnt have needed the OBDII, just the Power from the harness for the Road Runner.

I spoke with Craig about this. If your USB port supplies enough power, you can flash the RR while it's out of the car. This is only applicable with the USB connection. The BlueTooth option does require the PCM to have power.

Yup. I have flashed mine countless times on the bench without a power source and it works just fine.

I can do this with both my 98 roadrunner, and the 99-02 one I have.
