Is it common to set up an exhaust gas temperature (EGT) meter and a probe for EACH seperate cylinder in order to get a pricise tune?

In fact, if you just monitor AFRs, is it even worth it?

I am an s2000, boosted near 600whp currently on a mase kit, and i'm running hondata flashpro as my ecu and I have an AEM UEGO wideband.
My new possible tuner (who supposebly has over 15 years of reputable experience) says he wants me to get them for when he tunes the car after hes came across issues with my exhaust valves being burnt, etc. that hes fixing.

I've never heard of this being a common or needed thing, especially if im getting wideband readings, so I just want to make sure my money would be well spent.

Have any of you heard of tuners monitoring all four cylinders with seperate egt meters for tuning eventhough the car already has wideband and flashpro ems?

PLEASE GIVE YOUR INPUT thanks!

 

I would say 99.9% of the time this isn't needed. It's certainly helpful for the tuner...

I'd say individual EGTs or 02 sensors can really only be necessary on a race car that is always on the edge of bad potential things.

I would think so too, but heres my problem:

when i took my exhaust manifold apart, there were HUGE differences in carbon buildup per cylinder which may have been the cause for some of my exhaust valves being burnt amongst other things... its causing unequal distribution of exhaust flow which could obviously be more prone to knock, loss of power, etc.

Thats why this setup for me might be the smartest thing to do to see what may be causing the problem and to get this tune right per cylinder. But the money for it is just not certain so im wavering my *** off.

 

If your cylinder trims need to be wildly different, then either your injector flow rates are different (easily fixable) or the flow of air across each cylinder is different because of manifold design (intake or exhaust) or more than likely uneven port work.

 

I'll second everything Chris said, but I voted "other" because you don't have 20/20 vision as an option.

Reading the plugs will give you a better indication of what's going on in the combustion chamber than a EGT value. Every engine combo. is different and will "like" different things, for example: generally speaking you'd target a 12.5 afr on a N/A engine, but if your particular engine makes more power at 12.2, will you target 12.5 anyway just because everyone else does? I would hope not... EGT's are exactly the same, good for a general rule of thumb, but ultimately, you do whatever the engine responds to best.

And reading the plugs is the quickest, cheapest, and easiest way I know of making sure the combustion chamber is happy.

 

If you want to get even more crazy and accurate than EGT as we all know they react a little slow. Run a 4-Channel Wideband setup from AEM. Than you will know exactly what is going on in each cylinder. But as most have said reading the actual plug will give you a lot of information and pull your injectors and have them cleaned and flowed to make sure they match each other.

 

yea, that 4 channel aem wideband looks nice, but since I already at least have the uego aem wideband, I'd figure i'd consider monitoring egts per runner...
heres the websites I'm looking into for the meters...

Thanks a lot for the helpful info guys

 

Looking real quick I didnt really see one that did all four at the same time and not reading them all at the same time won't really help much.

One thing you have to remember is that the wideband setup you have now is just taking a average reading across all the runners and its installed after the turbo. If you are that concerned about the tuning across all cylinders I would suggest the AEM 4-Channel Wideband with back pressure compensation. Than you can mount the Wideband sensors pre-turbo about 2 inches away from the head. You don't get more accurate readings than that.

I completely agree as the aem 4 channel would be very helpful, but I went ahead and ordered 4 seperate egt meters/probes last night from auber instruments to connect to each runner. I like them because they can be used as seperate wideband meters too, or for any temp readings in the car for that matter, as long as they are tapped wherever they need to go with a probe.

so for now, im going to run the meters for all 4 runners during the tune. once the tune is done, for driver monitoring, Im going to take out 3 of the probes and connect them to read 3 of the following instead: transmission, diff, oil, air intake, water temps or maybe even use them as seperate widebands (still not sure yet).

I will use bung plugs to cap the hole from the 3 runners they were previously on.

At the same time, im going to leave one meter/probe on the leanest runner to read egts.

Thats why i love these little auber instrument meters. They have interchangable probes to practically read anything so its like im buying 4 new gauges that can monitor anything I want once the probes holes are tapped. And they are relatively inexpensive. I paid 338$ total for all 4 meters and probes. thats about how much it would cost for just 2 regualr gauges on the market. these things are pretty cool
