So Im looking at getting a hondata flash-pro and selling the apexi neo. Any and all info about what I need to get and a must have would be great. also where is the cheapest place to pick one up?

Also ... do I have to leave it in the obd2 plug while driving if not doing any data logging, or does it flash my ecu and then I can take it back out? Because in that case could I just use someones that has one and take my car and have it tuned with it?

My car info ( 2007 AP2 S2000 )
