pros and cons..

any reason why i would need the commander over datalogit..

have had the pfc with commander but dont see any reason to not just have the complete flexibility of just a datalogit...

commander is handy when it comes to monitoring your car's vitals. it would be kinda hard to keep your laptop open and running everytime you drive

ah just build the car right and ditch the commander

Get the datalogit and the commander. Commander is nice for quick views, i have mine mounted in the car. It is nice to have real indepedent gauges though, incase one of the senders fail or whatever..

You NEED the Datalogit to access all of the PFC's base maps, and features, without it you will never be able to tune it properly.

I have both in the car, and would reccomend the same for you. The commander is good to have to monitor all the important stuff, and to make quick changes to things like idle, warmup, etc. The datalogit is needed for doing some real tuning, and real time data logging

where can i get a datalogic and how much do they usually cost im assuming somewhere around 2-300
