HP TUNERS 3.0 doesn't record injector duty cycle in gragh

I have done a search and also emailed HP about this. HP sent me back and email with links to set up a wideband. In searching I found a thread where someone explained a complicated way to figure out IDC. I just want it to work. The gragh does show IDC but it is not being recorded. Thanks in advance for any help.

I'm not sure exactly what you mean by that? That there's a chart called injector duty cycle? BFD. Is that chart layout set with injector duty cycle as the parameter? Are you logging all the parameters necessary to calculate IDC?

ok i just tried this out. i'm using 3.2 mind you.
go into the scanner > channels and add channels
engine rpm sae ( i think this is under engine, or may already be added if you have RPM in gauges or graphs)
injector pulsewidth bank 1
injector pulsewidth bank 2
you dont have to add those to gauges or graphs, they just have to be an active channel so the computer can use them to calculate duty cycle.
I'm not sure what else it uses to calculate the IDC, I am no tuning guru. Does is it uses your injector flow rate vs kpa too? I'm pretty sure it does not and it's just a calculation, so as far as accuracy...I'm not sure it's very helpful.

That did the trick. Thanks for everyone's help
