I was wondering if the probe for an egt will fit where the o2 sensor goes? I was just gonna stick it there since I dont use the 02 readings anways.
Does it fit there?

 

hmmm it depends what brand gauge you get. I have a Greddy 52mm EGT gauge and i had to use a brass bushing to reduce the size. Im glad my RB DP had 2 bungs.. One for the 02 and another bung as a provision for EGT probe.

 

this site here has an adapter for your O2 bung http://www.rjcracing.com/EGT_Gages/egt_gages.html

I have purchased an adapter and an EGT probe from them.

If you would like to purchase a cheap Fluke meter to read the egt(s) pm me.

 

it's an autometer pyrometer. I just wanted to know if I can take out my o2 and put that in it's place but thanks

 

The threading on your Autometer probe is most likely an NPT type, possibly a 1/4' or 3/16"which cannot be threaded into he O2 bung.

The site that I listed sells an adapter that allows an NPT (3/16") threaded probe to be placed in the O2 bung. If your probe is a 1/4", you would need a 1/4" to 3/16" NPT fitttng plus the adapter sold at that site.

The 1/4" to 3/16" NPT probably can be purchased at a local hardware store.

 

how and why do you not use your 02 settings?

 

Don't know if the question was for me, but I run a PFC with a wideband and the O2 feedback off. I have a second O2 bung (with an adapter) for the egt probe. That is how, the why of it is, I datalog my egts and AFRs at times.

 

Uhmm, you can't really remove the 02 sensor as it's used by almost every ecu available.

 

you dont know much about the pfc no need for the stock 02 because u can turn off the signal and just run off of the maps

 

yeah i'm with books I've got a pfc and it's running off the tuning instead of a/f's

 

I just got a pfc preset for my mods but haven't installed it yet as I haven't put in my new intercooler. searched around in the pfc subforum and determined to my comfort level that not too many people really know much about the pfc. alot of pfc users seem to be reserved about advice, probably I suppose because they are gaining a level of tuning confidence by testing theory against results. probably the same with other ecu's too. Given this, I don't think the comment was fair to say you don't know much about pfc's.

It seems like removing the O2 and running off the maps is thinking outside the box. I recognize there can be some benefits for removal as well as some consequences from not using it. My next question is where did you guys come up with this idea and are there any other none obvious sensors considered for removal?

 

people dont want to give out tuning advice because they don't want to be responsible for any blown engines. u know how temperamental our engines are. if u'v searched around then u probably read that putting one map into 2 indentical cars, one will run better then the other.

if he did know anything about pfc he would know there is no point in running the stock 02 sensor because it would change the values that u spent ur money and time on setting up.
but i guess i could have said it a little more politely.

as for sensors, besides the 02 theres not any that u should remove because they are all needed to gather info to choose the right values. but some remove the fuel temp when changing rails because there's no where to mount it. the air intake temp sen should be moved because of heat soak from being right on top of the block.

 

I guess YOU don't know much about the PFC either....the PFC only uses the narrowband o2 sensor feed for cruise and light throttle -- just like the stock ecu. It will most certainly not "change the values that u spent ur money and time setting up." I doubt most people are paying a tuner to go through and set cruise and light load maps.

MOST PFC users still use the stock o2 sensor for fuel mileage. Others have specifically tuned their cruise and light load for use without an o2 sensor but that takes quite a bit of time and logging.

Oh, back on topic. Down the downpipe is a pretty poor location for an EGT sensor for several reasons.

 

I've noticed a few recent threads that probably at some point could be moved to the engine management / power fc forum. thanks for the responses.
