I have put together a ECU DATA acquisition and logging system for the Crossfire from third party products that will monitor / log / record the major engine parameters. There are 65 supported PID's with the basic system...

(1) You will need a PC running Windows with either a DB9 serial connector, USB connector, or Bluetooth connectivity.

(2) You will also need to purchase a ELMSCAN OBDII interface that has the connectivity to your computer (DB9, USB, BLUETOOTH). http://www.scantool.net/products/index.php?cPath=8_6

(3) You will also need to purchase the PCMSCAN software from PalmerPerformance. A demo version is available here: http://www.palmerperformance.com/

I am also awaiting delivery of the CARSOFT maintenance software which will interface with the ELMSCAN5... But, I am not yet sure that the Mercedes SLK320 software will be the same as the Crossfire... You can find the info for yourself here: http://www.carsoftsales.com/mb/index.htm

Enjoy the info... When I have more on the tuning software I will share it with the forum.
