    injector duty cycle and rpms

    im new to tuning and I cant get these to work in the gauges and the charts. they work on any other truck I hook up to. mines just a hit and miss it seems like. sometimes it will work and sometimes it wont. any suggestions? when I connect the rpms say its unsupported. and the injector duty cycle just doesn't show anything.

    Are you logging both injector pulse width banks and flow rate?

    post up a screen shot of your table view from your scanner on your truck. No need to log injector fuel rate to get duty cycle to show up.

    Go Tools, Options, Clear last vehicle used. Scanner should close, if not close it. Got to directory where VCM Scanner is kept. Go into VCM Scanner directory, then Vehicles Directory. Delete all the files in the directory. Then open up scanner, load default imperial config, and connect to truck and tell us what happened.

    Sure you looked in right spot, its just called Vehicles, and its there.

    Folder will contain: Configs, Gauges, Histograms, and vehicles.
