Performance Diesel Tuning Fundamentals | Lesson 1 of 4 [#FREELESSON]

With many larger modern diesel engines being 'over-built' from factory, it is not uncommon to easily extract 80-100HP more with only a custom tune. It's no surprise that more and more people want to learn how this is possible and understand how it is done themselves.

It doesn't matter if you're tuning a Ford Powerstroke, Dodge Cummins, Chevrolet Duramax or something else using HP Tuners, EFI Live, SCT, EZ Lynk or whatever platform applies to your application; you're going to enjoy these lessons.

In this first of FIVE diesel tuning lessons, we'll discuss some of the advantages of a diesel engine over a gasoline-based engine. One major aspect that we do not have to worry about here is the barrier or knock/detonation/pinging limitations.

We will also look at some of the electronic controls a modern common rail setup has, basic injection timing and pressure principles, and some torque tables without our HP Tuners software.

While tutor Nick Priegnitz used HP Tuners and a Duramax for this specific lesson, the concepts he covers on the fundamentals of diesel operation are not specific to these platforms, and later lessons do use a range of other options to help underline this fact.

Never ever had someone articulate this so perfectly. Made me feel smart for a minute. Thank you

[Bob-nuxe]

I have a twin turbo diesel with two maps available, normal mode and sport funny thing is the mpg doesn't really drop in sport the engine appears to run better great video thanks

[HollywoodCod]

Man this is really great content. Would love to see all parts of this. Eventually will purchase the full course but this is awesome

[griffinvideoprods]

How about a 2.0l TDCi MK3 Ford Focus. Can these be tuned above the base 161 BHP 120 KW 340 NM?

[jdmtake]

I’m having trouble with this 2003 Ford F-250 7.3 can’t read the pcm or write with HP tuners not sure what’s going on. The CCM monitor will not set any help

[guppylove]

I can not find anything for my diesel, or mini diesel I’m going to call it in relation to these beasts your playing with… I have a 1.6 litre tdci motor tiny but I want to modify it, I have had a stage one remap but want more … very limited in the uk 😢

[mikahelhavok]

Where can I find out what given components can handle my main concerns are cams and timing chain

[fbervaz]

Is there a difference between a diesel engine with a mechanical fuel pump and one with a common rail? Is the AFR limit with full engine load the same? whats is de EGT limit? thank in advance!

[sd_rcfanatic]

So leaning a/f ration makes more power?

The accessibility for end users who want to tune their own engine, but not spend a ton of money to buy a2ls, winols, lessons is just not there. I understand how I want the engine to run, but getting info on finding maps, switches in the binary is all locked behind huge pay walls. I can't justify a winols licence for my own pickup, so I'm to the point of trying to find things in the binary and modify it directly. I mean ez lynk will do a lot of the work, but finding things like how to ignore faults is almost completely undocumented.

WHAT IF THEY WANT
1, 115 PS (1, 100 hp; 820 kW) at 1, 650 rpm
Specific power: 11.3 PS/L (0.18 hp/cu in; 8.31 kW/L)
Compression ratio: 16:1
Specific fuel consumption: 0.175 kg/PSh (0.391 lb/(hp⋅h); 0.238 kg/kWh) at max continuous

Interested to know more about diesel tuning, but more about vehicles available in Australia rather than the big Yank monsters.

Just put an AMG Patch on it like a real Tuner and youre fine
