How can or where can I find out the Injector duty cycle?

Is there a percentage or something like that?

Cheers

Have a read of the faq, and the guides at the bottom and see if it answers your questions. You'll want to modify your ecu to get high speed data, as well as run a program with support for the high speed mod. Then you'll need some kind of suitable ALDL interface and yes you can then watch the duty cycle %.

Thanks for the Speedy reply Antus,

I've had a read through, but doesn't make a lot of sense just yet. Need to get my head around it.

So modding 8192 baud rate is the go? I've got laptop, ALDL cable, Efilive4 or tuner pro, EPROM programmer.

Usually, but It depends what car you have. I see in your profile it says vr v6 turbo? If its a manual with a proper VR manual ecu then you wont need to do this as that ecu had high speed comms from factory. If its auto then things are going to harder as you wont be able to run 12P. What ecu do you have?

If its VR (Auto or manual) you should be able to use your aldl interface and the flashtool here https://pcmhacking.net/forums/viewtopic.php?f=3&t=82 to read the bin file from it. If you post it up we can tell you what you have.

The VR is one of my projects, but looking at this for a VN/VP V6 Auto.

Cheers

If it's not in the adx already, this is what i use to work out Injector Duty Cycle %, Y is your RPM, just setup another item in the adx same as injector pulse width but with that calc

((x*.007629)/(1000*(1/(Y/60)))) *100
