Are Your EGTs Too High? | Exhaust Gas Temp Management in Diesel Engines [#FREELESSON]

Monitoring EGT has long been a common technique for assessing the safety of a tune in a diesel engine. In this webinar, we’ll discuss the validity of that technique and see how the EGT is affected by tuning changes. For this webinar we will be using a MoTeC M1 ECU fitted to a Toyota 1KD turbocharged diesel engine.

Due to the current global situation we thought we'd help keep you guys out there entertained and release some of these otherwise paid access only webinars to you for free to help pass the time.

What temp do you need to hit before you start worrying about your EGT?

[evil_me]

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.

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

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.

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

[janpapachristoforou]

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

[avlos]

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

[Nortifyer]

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.

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.

My 2.0 TDI (VW EA288 DBGC engine) had egt limiter at about 860 deg (celsius), now it has some tuning and its limiter had been risen to 930. Can I consider it as "safe tuning"?

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.

What wideband do you use to read 1.7 lambda?

[alexhise]

There's also PT-200 resistance curve egt sensors

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

[blackboxing]

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

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.
