When engineers were testing the 250,000hp nuclear scramjet engine for Project Pluto, there was no temperature sensor known that could measure the exhaust temperature, instead during testing of the full size engine, they designed a calibrated optical system to gauge the temperature, to determine how well the internals of the engine reacted to full power for 20 minutes. Pluto was an armored cruise missile, the size of a locomotive that flew at Mach 3.5, at tree top height, and its shock wave would have killed people on the ground.

@@justarandomguy3969 if you think that the O2 sensors are only for environmental reasons , it's pretty clear that you don't know anything about the stoichiometric ratio of fuels , and the advantages/disadvantages of running an engine too rich / too lean . Pretty sure that you should look into it .
@@bogdy2p i never said it was the only reason, but it is THE reason it was invented/put into cars. Its also the reason all modern cars have 2-3 of them instead of 1
Video suggestion - Biggest dyno fails the Haltech team has ever seen. Thought of this while rewatching the G6E tuning series, when Scotty mentioned the idea of turning up to the dyno with flywheels / driveshafts / CVs improperly attached. There's gotta be a few good stories there
The fact that you removed something do result in a temp drop on cylinder 2 means its likely the coil plug. But if you had not known the action that caused it, you could also think it was running rich. You could confirm this with the wideband as you have 2.
Hello from Finland! You wanted to know what happened to your test engine? I am going to guess that you unplugged number 2 cylinder coilpack was unplugged and im basing my guess on that because your number 2 cylinder exhaust gas temp went down right away amd your short term fuel trim is trying to reduce the ammount of fuel.
Good video, it looks like scott reached over to unplug the coil pack hence the drop in cylinder 2 egt. The wb barely ran leaner though, is this because the engine was at low load. Would it be much more obvious at higher engine loads?
Unburnt fuel can displace oxygen in the exhaust and show a rich condition or a large volume of oxygen with no fuel can show a lean condition, depends on your misfire condition, you need to look at the total picture, not just what the 02 sensor is doing, to determine what is occuring.
Is there a setting you can put in to detect sudden drop on one cylinder, so if the variance between all 6 is too far it will put the engine into protection mode, rather than only having a min or max value for engine protection.
Dude I work in a factory and these thermo couples are all over the place rarely do they give issues its usualy they get broken or wiring chafed thru so I can attest to the durability of these
Anybody have any opinions on longevity of EGT probes pre-turbine? Is it worth the expense of getting a inconel sheath? Still suggest running a open probe? I am considering getting open tips to verify the tune is healthy, then either removing them entirely or swapping to closed tips to watch for radical changes.
Hey mate my diesel egt's both read 80 degrees celcius when engine is cold, they do rise when engine is running. Im having issues with car . Is that normal?
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
Why not just have O2 sensors on each exhaust bank instead of EGT's? Is it because of the limited temperature range of oxygen sensors compared to the k-type temperature sensors?
Question @Haltech; @16:27 in the example you give where you can turn off that cylinder #2 if the EGT goes above the set limit. Instead of turning off that cylinder can you in the ECU have the Fuel injector send additional fuel for added cooling of that particular cylinder??? & would this be more beneficial? I can theoretically see the benefit in this but just curious What went wrong? @20:47 The EGT 2 shows it's a lot cooler than the other cylinders and thus I'm going to say It got more fuel as a result of no spark which resulted in the cooler readings & the engine mist or poor running condition... ?
I already have a TCA8 with my Elite 1500 for my 4 cyl egt's. If I get a thermocouple for oil temp. I know you can set it up to log it as oil temp. Can you set it up also for engine protection?
On your software and hardware is it possible to run 4 o2 sensors and 4 egt sensors? I don't want my built f20b engine to blow up due to lean condition in cylinder #2 or #3. I want to control all 4 injectors plus also have vtec engaging
i can say the 4 egt's i got on my sti is great. When i 2step my motor at high psi it has saved me and thrown limp mode at track. 920 degrees 2 cylinder's shutdown u pulled a injector . my egts are in by eye and under no load are 20 dregrees out, but under full load WOT there within 10degrees. that at the track
@@haltech I would have expected a dead cylinder with fuel to drop temp a lot faster, guess there just isn't much flow to cool the sensor at such a low throttle opening?

scotty, you ever wanna do a sloppy radio show with me?
Yes! This needs to happen
Yes
Do it.
Now this would be great

Thankyou for helping me see them as useful and not just engineered problems.
Cool video, was contemplating egt on my 7, will wait until the next time I have to pull the manifold, and yeah you unplugged the coil pack
mmmm the purity of instrumentation. No lies, just data.
Man I love the way you explain it amazing
Unplug the ignition coil on the cyl 2, love ur videos Scotty!
They are a tuning tool like a knock sensors and O2 sensors. They help optimize tuning per cylinder if you delve into it that far.
O2 sensors are there to make sure the cat is working aka its for environmental reasons
@@justarandomguy3969 you my friend , are SOOOOOO wrong... :)

Cyl 2 lost ignition, fuel or spark based. Damn Scotty, now I cant get an engine done without per cyl egt monitoring.
you sure know your egt's well done

No ignition cylinder # 2. Also notice the wideband was disconnected and connected back on.
You unplugged cylinder #2 coil pack temperature dropped due to no spark to ignite the air and fuel so that cylinder starts to lose temperature
scotty is always a fun watch
You took out the 2 Egt sensor. Anyway, I don't think the T-shirt is available anymore. :)
What are your thoughts on using egt sensors on 2 stroke engines? Specifically a 1975 kawasaki h1 500 triple.
I believe you unplugged the coil pack of plug lead on CL.2
I need something like this at the moment to find the gremlin I have running around my engine
Why is there a difference in position between NA and boosted applications?
Can you guys do a video on open loop vs closed loop and how these interact on a stock engine? And vs how they operate on a tuned engine?
Can the EGT Controller also work with other tempsensors? For example with a bosch Kombisensor?
Is there a setting you can put in to detect sudden drop on one cylinder, so if the variance between all 6 is too far it will put the engine into protection mode, rather than only having a min or max value for engine protection.
Looks like the injector was unplugged on whichever cylinder number 2 thermocouple was connected to.
Great video. Most helpful mate! Thanks
Reconnected the O2 sensor taking the a/f ratio off the egt’s and putting them back on oxygen sensors or closed loop
Dude I work in a factory and these thermo couples are all over the place rarely do they give issues its usualy they get broken or wiring chafed thru so I can attest to the durability of these
coil on cylinder 2. The temps was going down. Let me think that fuel was getting out and cooling the sensor
Speaking about egt connectors, if you hate money you can get size 20 pins to suit deutsch or similar connectors. They're like $20 bucks a pin tho.
Looks like cyl 2 unplugged - temps dropped quick so fuel still spraying.
Cylinder 2 Ignition coil unplugged, Temp on Cyl2 dropped off showing no spark.
Unplugged the coil pack on cylinder 2?
Are the T-shirts all given away yet. I know the answer. Whats wrong is that the engine in not a LS V8.
Anybody have any opinions on longevity of EGT probes pre-turbine? Is it worth the expense of getting a inconel sheath? Still suggest running a open probe?

Hey mate my diesel egt's both read 80 degrees celcius when engine is cold, they do rise when engine is running. Im having issues with car . Is that normal?
Cylinder 2 injector disconnect?
why is there a difference in performance of the depth of insertion of the EGT tip. what changes between naturally aspirated and turbo charged.
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.

Do you guys ever drywell test your setups to see if there in any difference between each ones?
Why not just have O2 sensors on each exhaust bank instead of EGT's? Is it because of the limited temperature range of oxygen sensors compared to the k-type temperature sensors?
Fun fact. The type N thermocouple was developed in Australia.
Can they be mounted on the underside of the runner, or do they need to be on the top?
How many k's would you usually get out of them?
