I just bought the new Superchips Flashpaq for my 2000 Jeep TJ. I wanted it mostly for engine diagnostics but tuning wouldn't really hurt either. Before I plugged it in I updated it and upgraded the unit with the Data Acquisition package as well. After that was completed I plugged it in my Jeep and followed the instructions for the 87 octane tune. It performed the file installation successfully. Then I decided to check the engine diagnostics. I got the error J1850 or CAN not found. All I want to do is check the DAQ 2: Display & Store PID Data for all the sensors and engine data. Please tell me I did something wrong otherwise I Just wasted $360.00.
