That'* a good point. Although I guess if I decided I wanted to see more, I could just strap my 27" down in the front seat and run it off an inverter. hmmm.....

Be careful with inverters. You do not want to run anything connected to the computer with a inverter when it'* plugged in to the OBD2 port. Although rare, there have been fires because of this. Something about feedback between the two different connections and burning up the car. I had a picture somewhere, I'll look.

Do NOT use a inverter when connecting threw a USB port. You will cause a feed back from the loop. Results are bad,

I didn't remember that as being Jared'* issue. Everyone I know that tunes with the exception of one person has no issues with inverters. Although HPT recently started adding the warning that you can fry the HPT by using an inverter.

Like I said, it'* rare, but not worth the risk in my book. Remember, your USB port provides power to the tuner, and there'* also power coming from the OBD2 port. Now add a inverter and that'* providing power to the computer. So the tuner is getting power from two different locations that are now connected by the inverter. Feed back loop.

Wow, that was even the same body style as mine. What about an external monitor though? I figured I would run the laptop on battery (although it'* good you mention this, because eventually I'm sure I would have plugged it in). The external monitor would be powered by the inverter, and the laptop would only be connected through the vga to send video, it would run on battery,

Might be OK, there'* now power exchange between computer and monitor.

That would be fine because there isn't any power connections inside a computer that would connect a usb and video port directly. The usb is however connected to the power because of needing to power devices. That connection is what would cause the loop. Also monitors don't really feedback power into the video port. They send a little amount to tell the computer what resolution is supported and sometimes other info, but not enough going back to be a problem.

If you have a UPS it might still be a good idea to use that to run the monitor just in case the near impossible strikes. Always good to err on the safe side

Better safe then smoking.

Anyone know of a good guide to hptuners/tuning. I see that they offer a class for $450 that although expensive is very tempting. I'm just curious if anyone knows a cheaper way to learn everything I need to know.
