Hey guys. Im new here and just got EFI a few weeks ago. Im having some issues with a truck I'm tuning. While at an idle in gear, I have a lope. I didnt change any fuel pressure at idle or any pulse width. (So I thought) I did some logging to find that at idle im demanding 4900psi but was fluctuating from 52-4700psi. So, I went into my pulse width chart and started lowering the values from the 5 mm3's all the way up to 0 over to 40MPa. And I still had a lopey idle. So, I looked at the scan tool, and moved the line around on the graph and noticed that it was highlighting the 190MPa column in the the injection pulse chart. Why is that? Is the CP3 getting weak and the valve is opening all the way to keep pressure? So, I lowered those values and it still lopes. But, load up the stock tune and all is good. I have a tune in my truck that has way more fuel in the same areas, and it idles smoothly. Im learning a lot but there is so much more to go. Thanks in advance for any help.
