DFCO light
Been thinking about how to help improve fuel economy, and thought a light that would trigger when DFCO hit would help a little bit, because sometimes i find i rest my foot on the pedal when i could be coasting. just a dummy light to let you know you're saving fuel.
Is this possible? i have no idea where to even begin about doing this one - i looked a little bit in the service manual but i didn't find anything... i was thinking of just using a small led since it wouldn't require much voltage to light up.

DFCO is indicated by one of the modes in the Fuel System Status OBDII PID. You would need a device to read the status from the OBD connector via CAN message to the ECM. With my YarGauge for FSS or also in MPG mode I indicate when the system is in DFCO. Devices like the ScanGauge have the ability to do so as well.

Yep, easiest way right now would be a Scangauge... It won't exactly show you that you're in DFCO, but the instant MPG's will jump up to 9999MPG, letting you know that DFCO just kicked in, yo!

There's also the UltraGuage which does just about everything that the ScanGuage II does, but it seems like it's a little more user friendly... I don't have either, but if I was to get one or the other, I'd choose the UltraGuage.
I think you can only order them off of their site: UltraGuage
