Can anyone help out with a CL2 datalogger. Have all of the necessary harnesses. Racepak 28120-2003, 280-CA-EFIHOL, and Holley 558-447 connected to my Holley Dominator. I can't get engine data to show on the CL2. Going to the GoodGuys show in Nashville this weekend, and I'd really like to get this working.
