There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

I got the check engine light on my 2013 STS. The code is P1171, which I know is lean on cylinder 1. I do have the Power Commander 5 with the O2 optimizer, JT's air filter, and Akrapovic exhaust. It ran great for about 200 miles on cool days, but now the weather has warmed up I'm getting the check engine light. Anyone know how to adjust the mapping. I have only loaded the maps provided from Power Commander. I've never messed with changing the values in the map file.
