I have serched my *** off, and I can't find any egt kits that will monitor/display all 4 cyl at the same time.

I have an autometer egt right now, so if I can't find anything ill just buy three more single kits.

Help me out guys, let me know where I can find a nice kit.

Thanks, onefstek.

 

I know you asked for monitor/display, and this won't, but it's kinda hard to watch all 4 at the same time anyway, no...?

Anyway, for datalogging on your notebook, here's one (the most cost effective and readily available, anyways)....

look into snow mobile and motorcycle setups. they have multiple egt sensons and gauges

I looked into the snowmobile ones, but they are only 3cyl ones that I have found.

ill look into the motorcycle and see if they have a 4cyl or 2cyl and then buy two of them. thanks again.

 

i've been looking for a 4-way gauge as well.

 

4way egt isnt really that useful unless your tuning by it.... which still isnt a very effective tuning method compared to dyno/wb02

Seems like a waste of money imo; i only use egt for 5th gear pulls to make sure i dont melt pistons- in which case 1 sensor is fine

 

It is plenty useful. Some cylinders run hotter than others. With individual cylinder fuel corrections you can help to correct this using 4way egt's to monitor. Also when your doing 5th gear pulls how do you know one of the other cylinders isn't hotter than the rest.

 

is that slight correction worth the (im assuming fairly expensive) cost of getting a 4way kit?

seems like people have tuned thousands of cars without the 4way why blow all that money on something that really might not help that much (so you decrease cyl #3 temps by 50F is it worth $400?)

I understand the concept i just dont think the ends justifies the means

 

Jeff Evans had some small digital screens FS a while back that looked to be like 1"x1" Ea. that he was using for x4 EGT.

 

In my opinion EGT's are only worth having if you have four of them...

To the op, sorry, i don't know of anything like you're looking for. We use the onboard datalogging systems in the race cars to do that.

 

The box that Turncoat posted would work very well along with some thermocouples. Check out Omega Engineering for thermocouples (or even better call them and speak to an applications engineer), last I checked they were pretty inexpensive.

I agree with Tony that they're pretty useless unless you have one on each cylinder though.

I do alot of r&d with my car and I want to know whats going on in each cyl. Especially when you desighn an intake manifold with different shape plenum. I know that #3 cyl runs hotter on our cars, but that can differ from car to car and set up to set up.

I found some just today as I was doing some more searching http://www.redlinegauges.com they seem like a good set up, especially alowing you do hook it up to a laptop and datalog all four.

I totally agree. I had one in just one runner and it does not help if your #4 injector decides to take a shiet.

 

Check out National Instruments as well for Data Acquisition boxes. They have boxes anywhere from ~$100 on up to several thousand dollars. I'd say its a better route to go as you can hook other inputs into the box as well and display everything on a computer screen.

Here's an example of a Senior Design project some kids at my school completed this past year. Its an engine dyno, but check out the data acquisition section on this page.

I have four EGT probes. I use the Techedge wideband which has three thermocouple inputs then I just used a external thermocoulple amplifier chip for the 4th probe. Works well. I used it to tune the fuel trim in each cylinder and I use TEWBLOG as a warning if I get too hot or too cold in boost. With the DIY kit I ended up paying a little over $250 for a wideband controller, O2 sensor and four probes.

Here's a source that one might not think of. Look to the aviation industry. Their gauges are somewhat cheaper than those of the auto world and if it goes in an aircraft, it will be reliable and accurate. here are a few links to get you started.

This one is my personal favorite, however, they are changing there website, so pics aren't up. They have single gauges up to quad gauges.

Im an aircraft technician, and the first ones I checked were the aircraft ones. But im sure that all of them operate on 24vdc.

 

Tiny Digital EGT screens, 2nd one down http://www.turbobits.co.uk/aca....html

 

I would definetly look at aircraft gauges. My dad has a beachcraft Bonanza and his EGT has 4 sensors. the gauge can look at all of them at once, do averages and display the % difference. pretty neat **** IMO

 

Another still from Innovate specifically for automotive, asides from national instruments and measurement computing above which I'm more familiar with...

Dude, you're being spoon fed. Pick one... and tell us how it works for you.

found some pics for you to view. Hope this helps.

in regards to aircraft being 24v, that is true in a lot of cases, but these particular gauges can be set up for 12v. Many homebuilts use either 6 or 12v systems. I think these look pretty cool and are functional.

here is a link to many pages of the various combinations they offer, you can get the face of the gauge to show more values/range, just depends on the size gauge.

The problem with what you posted above is they are not very specific in their ranges.... it moves in 2k intervals, with the digitals I posted above they give you a precise reading which is better to tune to and not just monitor.

 

I don't know if anyone has mentioned this yet, but how about just wiring 4 thermocouples to one gauge via switches. Just put 4 switches on your dash and you could switch between probes pretty quickly to see what's going on.

 

There is a thread on here where someone did that.

One gauge, 4 probes and he has a way to switch from one probe to the next to check readings.

Personally I think a wideband O2 is 10X better than EGT gauge. EGT gauge tells you your hot.....a wideband tells you why (rich/lean) so you have a better understanding on how to fix it.

you are forgetting about ignition timing and seperate individual cylinder requirments.

 

whatsabout 4 widebands, one per cylinder??
