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. |

Tried that also. It should be there. It is in the box on the left just not recording a value |
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? |
yeah he's asking how to set that up i believe it's a calculation of pulse width and rpm. i had it set up when I was using 2.24...and lost all my configs when 3.0 came out. |

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. |

I also figured out how to add both my portable WB and my permanent WB to my charts configuration.... With the help of all the great folks here and at HP of course. This stuff is so much more fun when it begins to go your way. Thanks again |
