A friend of mines told me to run 1 EGT in each cylinder for the best fine tuning with at least a good gain of 15whp. He said i can get any generic brand gauge will do it's job. I recently saw a 5 gauge combo set for $300 for the Megan racing gauges. Is this worth it putting 1 EGT in each exhaust manifold runner?

mite be if you had itb's

 

It's worth it. I'd get something you can integrate into the EMS so it does individual cylinder trims based upon EGT's incase one cylinder starts getting too hot.

AEM EMS, Hondata S300 & Neptune etc all do this, it is basically pointless to run just one EGT (just for ***** and giggles really), but with one in each cylinder like "backpurge" said you can adjust the fuel trim in each cylinder for maximum power and to make sure every cylinder is firing exactly the same. Evans-Tuning had some digital EGT gagues that he had for sale in the classified section a while back, maybe he can tell you where he got them from.

 

It is definetly worth the money if you reall want tho they do make computers that can go to each cyl. Im trying to remember but i do belive they sell them at jegs and summit if not pm me and i can get you more info

 

Pointless unless you can datalog it...

Also, not gonna be worth much power either. Would only make a big difference if you had a horrible intake manifold design that fed certain runners ALOT more than others...Nothing on the Market for B Series is THAT bad...

Any EMS that is going to be able to do individual cylinder trims is going to be able to log egt's. You will make more power doing individual cylinder trims, keeping every cylinder operating at maximum output, how much, is tough to say (depends on the motor's design like you said).

It's also great from a safety standpoint of the motor, keeping it from running too hot in maybe one cylinder that not getting as much air as the others at very high rpm's.

Also helps with troubleshooting. If on a V8 with a coil over plug setup, one coil isn't outputting enough, and you just have a wideband hooked up, you could easily tune around that bad cylinder, think the tune is great, but not making near enough power. If though, you had egt's on each cylinder, you could see one is running cold and troubleshoot it from there.

That's False...I can trim Individual Cylinders with S300, Neptune, etc..etc...and none of those have 4 thermecoupler inputs for EGT. I don't even think AEM has enough inputs...hell, Even most Motec don't. FAST Definately doesnt...

Which Standalones have 4-8 extra inputs for EGT?

 

AEM, FAST, and Motec all have the option for it.

Motec - http://www.motec.com/products/kits/hondakit.htm

"Upgrades for Base Package - 1/8" EGT Probe Kit with 90 degree K-Type Thermocouple and Amplifier"

AEM - I know you can program and datalog any analog or digital input you want, just have to know how to set it up.

FAST - I know you can program and datalog any analog or digital input you want, just have to know how to set it up.

I guess I just dont consider Hondata and Neptune to be "standalones".

 

You aren't understanding what I'm saying...They all have the option for it...but not enough inputs for it. So you can't do it...I know for a fact Motec M4 Pro is out of inputs, because I've installed it...M48 would be cutting it super close depending on how your setup. Motec sells an expansion Module to add Individual EGT. Anyways, it is out of the realm of most people...and honestly is pointless for 99.9% of people who have "Hondas". Sure, there are alot of shitty V8 Intake Manifolds out there that don't flow evenly but that isn't the case for our cars.

I've seen a 1700whp Turbocharged Viper that only varied 50 degrees between the 10 Cylinders in EGT...and that was before ANY Cylinder Trimming. Like I'm saying, in theroy yea you should have EGT in each cylinder...blah blah. In my personal experience of tuning a couple hundred cars...It's not needed.

 

I agree they're not needed, but they help. Hell at a certain point you really don't need any gauges, but at a certain point stuff is going to break if you're in the dark about what the motor is doing.

I love how at first you say Motec, AEM, and FAST can't datalog EGT inputs. Then you say, well..... Motec can and you completely ignore AEM and FAST which both can.

Arguing for the sake of arguing?

 

Dude...they all can...this all depends on the engine setup and what outputs and inputs are in use...but most of the time you aren't going to have enough free inputs to do individual egt. They all can log it, you can make any Standalone log anything practically...but there aren't enough inputs.

You are the one arguing for the sake of arguing...Im posting real world experience and you keep copy\pasting stuff from websites. I'm just keeping it real...it would be pointless to put 4 EGT gauges in a car...who can pay attention to 4 different gauges in the middle of a dyno pull and remember a small difference between all 4 in order to make a tuning call. Cmon now...

Me and my siamese twin can do it

 

Why not just run 4 sensors and one guage/input/etc, then run a relay to switch between them? With a bit of extra thinking/calulating, it would work fine.

If you already have spent thousands on the engine/ems, then a few hundred for individual pyrometers shoul;dn't be an issue.
