I was doing some logging today to try and figure out why at about 110mph my truck cuts out. Well i have no idea why it does it but from a 23k desired in frame 117 with 100% throttle im at 2900 microseconds with an actual rail pressure of 23400, in frame 118 100% throttle im at 2900us same desired and an actual of 23060 which is 340 psi lower than the previous frame. Now bare with me here this is where it gets interesting.
In frame 119 with the same desired rail pressure with an actual of 24063psi im at 1612us, which i feel is the start of the cut out. In frame 120 with the same desired rail pressure, the actual was 26105psi with an 934us injector opening time i think this is the end of the cut out. Now my next frame actual is 25kpsi and im climbing back up to 2200us. Frame 122 my opening time is still climbing and is at 2600us with an actual rail pressure of 21044. The next few frames are pretty consistant it stays at about 21500psi and about 2600us. So with all of that information right there what would you guys say the problem is? Obviously the pressure spike is the reason right?? I honestly have no idea. So what causes the spike and when it does spike what causes the injector opening time to pretty much slow way down? A couple of weeks ago i was doing the same thing and it cut out so i just kept trying to make it do it and i got a maf code i cant remember what it was but it was maf high voltage id o know that. What do you guys suggest i do first? Thanks in advance!
