There are two reasons I want and extra computer; I like the idea of being able to return it to stock for Smog inspection reasons and in case I need to resell, second I don't even have a driveway so flashing the computer using a laptop on battery power and using a wifi outside seems a little too risky for me.
The GDE programming tool meets both your requirements. It can hold up to 3 tunes so you can easily switch between stock and 2 other tunes at will. The programmer is completely self contained and doesn't require a laptop connected to it at the time you flash or read the ECM.
When you receive the programmer you take it to your vehicle and use it to read your ECM
Next you bring the tool inside, connect it to your laptop and download your stock tune to your laptop and email the file to GDE
They will take the vehicle specific information from it and create a custom tune for your vehicle
When you receive the file back from GDE, usually a few hours, you simply connect the programmer back up to your computer and upload the new tune to it.
Finally bring the programmer, without laptop, out to your vehicle, plug it into the OBD port and flash your new tune
A second, used, ECM will cost a little bit less but switching tunes is not as easy and if you want to switch from ECO to HOT in future you can do this by simply getting Keith to email you the new tune.
The only downside I see is that having a spare ECM could be useful in the unlikely event have a failure.
