Tuning a P pump to spool BIG turbos! AFR data, nitrous control & more!
Ойын-сауық
This video is an in depth, hands on, data driven explanation of tuning changes YOU can handle yourself to help spool big turbos on your mechanical injection engine! I show rare Air Fuel Ratio (AFR) data and explain each change and it’s direct effect. If you’re looking for a half hour of p pump tuning information this video is for you! #ppump #tuning #cummins #diesel #12valve #mechanical

You are the man Logan! You are helping a lot of DIY home budget guys! Applying your concepts has grown my racing confidence within my own build. As many of your other videos have taught me, even this one although talking about ppump tuning, your discussion on afr and egts applies across the board regardless of engine. Grateful that you share this information, keep it up 💪

Thank you very much for this comment!!
Great explanation of tuning the afc. Thank you.
You can weld up the afc foot ti cut even more rack out of it. Also you can adjust the lever on the gov that hits the afc foot so it contacts at the bottom of the afc foot then taper grind the afc towards the top so as the rpm comes up the fuel increases as well. You can use a hook shaped fuel plate to do similar just knocking the bottom out of it. because you never need big fueling below 3k with your setup.
Logan, this is the most indepth afc tuning video ive seen...mine wasnt even this indepth!!! Awesome Video!!

Thank you! The AFR data should be able to help some ppl!
I got a question could any of this tuning Apple to a stanadyne db2??
Awesome video super helpful Can you run a afr by itself or does it need to run to a logger or ecu of some sort.

I’ve not looked into stand alone wide bands but I’m sure there is some option out there for that

@@LoganbuiltRaceShop I know aem makes a afr gauge but not completely sure if that would work as a standalone seems like you need a ecu.
What do you use for data logging? And wants the old vs new turbo specs?

If you watch the last video & the “I bought a huge turbo” video I go over all the specs & reasoning for the change. The old turbo was an 88/103. This one is a 98/108. I use racepak data logging.
Lean for turbo spool? Why not more heat being rich?

EGT goes down when fuel is added and spool up slows as well. Lean is mean!
