Pulse width? Is it high already or what?
How big are your injectors, whats your max pulse width, What are you commanding for rail pressure? Still BIG cp3?
Twin cp3's commanding 25500 holding 26600 100 over's
Are you getting the DES pw you are asking for? If so increase pw
desired is 25500 actual is 26600
Todd, He means pulse width of the injector not the rail pressure. How big of a pw are you running. 2200,2400,3200 etc.
Seems like your running good rail pressure so I would add more pw to the injector if its not real high already. We have ran as much as 3200pw with 80% injectors on a lb7. The truck seemed to like big pulse width with big sticks.
pw 2650 running 2650
Like Eric said I just wanted to make sure the pw you commanded is what you get
My stock pumps with 2600pw will hold that rail its not until I get to 2900 that it starts to drop
If you don't want that much pw and timing you will need bigger sticks
bump the pluse width up until you start to loose rail pressure then back it down until it substains desired rail pressure just like simon said. I would also advance timing with the added pulse width.
For every 200us I go 1* useally
Thats a good rule of thumb simon. Alot of people are scared of timing. I always ran a max of 39* with my stock injectors and 3200pw. Nitrous and water/meth was the same exact tune. My engine looked GREAT outside the bent rods lol.
what tables do i need to change to get the timing up
Injection timing base C
thanks working on it. had a great weekend pulling even with the issues. I knew with all the changes there would be some testing. nothing broke & we learned a bunch :thumb:

why no more big cp3?!?!
are your two cp3s stock or modified?
