Which sales code are wanting to have flashed? The software that I use is AutoEnginuity. The Autel is great for adjusting the TPMS settings but doesn't offer much in the way of adding sales codes. Technically, the AutoEnginuity doesn't add sales codes either, but rather it 'enables' the options. The difference being that the added options are not stored in the FCA system and if you ever have to get the BCM flashed by the dealer (not likely but not impossible), you're likely going to lose those 'enabled' options. If you're good with that, then I do rent the AE software on a netbook that is less than your cheapest dealer and you can enable as many options as you'd like. Shoot me a PM for details.
There are hundreds of settings but here are a several of the popular ones ...
Add: Fog Lights, Heated Steering Wheel, Heated/Ventilated Seats & LED lights
Adjust: Different sized fuel tank, Speedometer for larger tires and Change the country code
Enable: LED lights, Daytime Running Lights, Heated/Cooled Seats, Door Panel Lights, Fog Lights with High Beams & Transmission Re-learn Process.
