this would be my very first step of modifying my car!
please understand, If im asking a noobish question :(
I'm driving 2007 mcs r56 and looking foward to get an Access port system.

I've done some reading about the Access port, and noticed there are 3stores that i could possibly order it from.. (rmw, alta, and cobb).

do they come with different pre-sets of map depends on where it ordered from???

if so, which one would you recommend for a stock 2007 mini cooper s (r56)

 

Cobb is the mfgr and will refer you to Alta for the Mini applications. RMW buys them from Alta with a slight mark-up. Alta is probably your best source. For a stock mcs there are 10 - 15 different pre-loaded maps on the AP. If you keep your upgrades to off-the-shelf kits for mcs, you should have minimal problems using the pre-loaded maps.
Be advised that if you start getting extreme with your upgrades, there are few people with the capability to create or modify an existing map. So far I've only found RMW and Alta, but I'm told there are more coming up to speed with the AP.

 

I'm not sure what the price differences are, but I'd say to order from RMW, just to have Jan as a resource. He's a great guy to work with and if you ever find yourself near one of his tune events, he can make you an excellent custom tune. In addition you'd get the alta maps I believe.
