Cummins Injector Pulse

[tylerltr450]

Hey guys I'm doing some tuning and I want to make my stock injectors act like a little bit of a bigger injector. Im wondering what is a safe range to change and can you move the peak around a little bit in order to help mpg? or do you have to leave it at the stock location?

Thanks

Lower right corner is the area for power and max pulse depends on trans health.

Changing cruise pulse to help MPG requires you to log your cruising are to see what cells are in use.

Hey Lez,

Thats my other problem I data logged about 5 times before and now it wont work. I tried reconfiguring everything and it still wont read anything. Since I wanted to log my crusing cells but it wont work anymore. And no worries on the trans im swaping my auto to a nv5600 next week so ill be able to hold the power

I followed the steps in this lets see if it works or not.

I wouldn't think changing your PW in cruse would help with mileage... If you reduce it there truck probably will just command more fuel by increasing mm3

That's where logging comes into play...drop it low enough to help but once it moves into another cell then you know how far you can go.

Lez any idea on whats up with my data logging. Do you have to have the v2 plugged into the truck before you turn it on? Or can you just plug it in while the truck is running. I did the setup from that link and it still doesn't show data. It shows all zeros and -20 for main timing degrees

Well i figured out my data log problem. It is because im on a old os and not on the csp os. So once I change that ill do some data logging for cruising and hopefully I can figure out a way to increase fuel mileage.

Big thanks to Lez,

Helped me figure out my uploading tune errors. So now ill start data logging and we will see what I can do with tuning the durations. Yes I did test it and it works with data logging now.
