Can't connect?

Hi,
this is my first time to mess with EFIlive. I plugged it in to the OBDII port with the truck turned to "run" and connected the usb cable. When I try to do anything (get calibration details, etc...) it cannot connect to the controller. I'm sortof lost on what to do.

'02 Chevy LB7

Thanks,
Daniel

edit:// V2. Also, it doesn't light up when plugged in to OBD only.

Dead cigarette lighter fuse....

It works now...




as per the attached balance rates...

is it time for new injectors?

Normal rates are +/- 6 drive/idle, yours look ok...

If you believe your injectors are going are are gone, check your injector pulsewidth too.
