From tuning large displacement diesels I have found that timing is the best way to get power but the easiest way for inexperienced people to destroy a bottom end. At a certain power level you will need to get bigger injectiors. Using the proper injector for the power range can make a big difference in EGTs, same power with lower EGTs is something I have seen often.

I have hight egt . After replacing 4 New injectors and injectors . Its for 2.2 d captiva in m'y 2.0 cruze . Can you help me

Bigger injectors allow a greater timing window for a given fuel demand. In a P-Pump you need bigger pump plungers too.

Excellent content here guys! EGTs are prob one of the most frequently misunderstood aspects of diesel tuning out there.. Keep up the good work! 😁

Hi, Thanks for the info! I want to know the fuel rail pressure, how far can one raise the fuel rail pressure from stock? If max pressure is 1500bar or 1800bar.

Hai... I would like to ask.. how much the temperature increasing after deleting/blicking EGR valve?

So what about when adding exhaust heat wrap and turbo blankets? This will increase the overall temps but does it not help with scavenging to bring cooler air into the intake.

Hi so where do you install the egt before or after turbo on a gas motor and what is saf egt for that

Do you have a video on adding water methanol injection? I'm running a Colorado 2.8l, with a dt44 turbo, water methanol injection and a crx intercooler. Thanks for all the knowledge.

Can an Tune show an error for the DPF temperature P24C700 ? can we adjust the EGT temperature so that we bypass the error ? Thanks !

Diesels are awesome.

Is the Motec system available for Isuzu Dmax ? Does it have the ability to control automatic transmission?

I can't give you a solid answer on that myself sorry James, not something I have looked into personally however MoTeC themselves will be able to tell you everything you need to know, give them a bell - Taz.

There's also PT-200 resistance curve egt sensors

About the same they are a lot easier to implement and more robust

What wideband do you use to read 1.7 lambda?

Every LSU4.9 can read that

Exhaust Gas Temperature (EGT) pre-catalyst Exhaust Gas Temperature (EGT) post-catalyst How do they calculate the temperature? Because one calculates very quickly and the other calculates much more slowly. And lags behind. Volvo xc 60 2.0 disiel D4 engine

I understand that the question of how high is too high on a egt is hard to answer.but lets saying everything is fine injection timing etc.isnt there like a sorta standard. eg at idle between 100 and 200c is normal, or eg up a steep hill egt hitting 600c between 800c is normal. Depending on car or truck. What is the point of a egt gauge if we dont know the safe working load. Sorry if i missed it in the video.if i have i will re watch.cheers

Not sure about other brands, but Isuzu release a data sheet on their engines with the safe EGT value.

I have a 2011 1.6 TDI VW that's remaped and in the 4th gear at about 3500rpm+ the ECU is cuting my injection beacause the EGT reaches 850C. Anyone know the cause of that? I have no fault codes. Thanks.

It could be a number of things, even something not quite right in the tune. You need to log some data and check then go from there. No good to have us or anyone else just guessing as it could set you off down the wrong path - Taz.

@@hpa101 thanks but what should i log? Idk about the tune, it runs in some kind of protection that i think the tuner set at 850c EGT.

So what’s the maximum EGT is safe?

@hpa101

There isn't just one safe value as it depends a little on the setup, but, 1350 Fahrenheit/730 Celcius is generally considered the absolute maximum for the vast majority of applications from a reliability standpoint. Personally, for my own diesel engine application and how I use it, the head is a known weak spot when it comes to heat and cracking due to a poor cooling design for the last cylinders (it's an inline 6) so I try and keep it under 600c. I am also not racing it. Some others in race applications will get as high as 1600F/870c, but that isn't always sustained and they have the setup and sensors to match, as well as the willingness and budget to take risks in the name of competitive motorsport - Taz. www.hpacademy.com/technical-articles/what-is-a-safe-egt/?

More pithy would be more effective

Get to the point stop dragging it out
