I'm missing it some how but I can't figure out how to get the injector duty cycle. I call myself looking at everything in TunerPro RT and i just done see it. I have searched but all I have came up with so far is people taking about what their duty cycle is, not how they got it.
Is it in the data stream or do I have to use other factors to figure it?

I don't think I'm maxed out but right now I wouldn't know if I was.

After the better part of 3 years down, my camaro is back running and after relearning everything I have forgotten about tuning over the past 3 years its getting close.

Thanks in advance,
Dewayne

 

Inj. D.C. is based on rpm. You have a lot more time to open/close at idle then you do at 6,000 rpm.

So it is a factor of (Inj. Open time)/(available time)

There are some online calculators if you want. Look up your max rpm, find out what the inj. dc is and rpm, put in calculator and done.

I do believe tunerpro can calculate it on the fly, depends how you setup your ADS file. Fairly certain no GM ecm spits out that data directly, just the Inj. PW. You will have to do math from there.

Thanks guys. I work nights and it gets boring as hell so that when I do my research. Sometimes I think I'm so bored that I don't see something when its right in front of me.

Thanks again.
