I was wanting to get an EGT to datalog. I am looking at using an Innovate Wideband setup with the RPM module. It will let you datalog 4 or 5 additional things with 5v inputs. I found a link on another board for a 5v EGT probe to use for datalogging here:

EGT for datalogging setup

Anybody here logging their EGT? How did you do it..... and what hardware did you get?

Thanks.
 
I had nothing extra to do with my money(YEAH RIGHT!!) so I bought the LM-1 and the LMA-3 Aux box...Built-in EGT...just get a probe kit(got mine from SMC) and away you go..inputs for tach, and also a built in 3bar MAP..You can log everything and correlate it all with RPM's, speed, etc etc...There are a couple 5v inputs as well, if you wish to log something else :)

I also have an lm-1 and lma-3 auxbox which I tried to connect to the probe (type k thermocouple) which has been used to send an egt signal to my Omega (brand name) electronic temperature display meter. I finally gave up using the lm-1 and auxbox because I was not confident with the accuracy and speed of the egt information being displayed. One of the main reasons I bought the auxbox was for it's egt function; however, I now use the Omega meter for monitoring egt. Do you get a good egt display with your equiptment? If so, I'll try to connect mine again.
Thanks,

I also have the LM1 with the aux box and attempted to log egt. I tried changing voltage inputs to get reliable readings and went back to the stand alone egt meter. Same result trying to log boost......
 
F.A.S.T is about to release a EGT box capable of 8 probes that can be datalogged direclty thru an XFI,I do not think it will work with the old box .

Otto,

Did you check the link out above? It appears several on that thread have tried it and it works great.....I want some people more familiar with datalogging on here to verify that it appears that it would work.......
 
After checking it out if that is the probe you would use i would not recommend it for accuracy. The most accurate fast acting probes have an open wire element on the end,The one posted in the link above is a standard probe and a bit slow to return actual temp.Meaning your egts may already be 1800 when it says 1600 because it cant read temp fast enough,Exhuast temps change very fast and can have big changes in a n instant which that probe would not read accuatly
This is what i have found playing with EGT's for a few years
In the pic below you can see the tip i speak of
not sure if it will wrok with that setup but most likely wil,just using this probe would be more accurate

Good question...Since this was my first EGT setup, I dont know..I do use the probe kit from SMC, so maybe it's a bit slower like mentioned..dunno, suppose next time out, I'll have to borrow and egt meter from someone and compare. I do have it jacked into the CHT/EGT connector and setup the software for EGT and my probe is just below the O2 sensor on opposite side of pipe..
 
I log boost and AFR with the Innovate lm-1 and lm3-A equipment and have confidence in their accuracy. I wish I could get to the same level with the egt, but so far I haven't made the grade?????????

That appears to a "K" probe Otto.
 
How often does that logging system update the EGT? Seems like that would be a limiting factor on how usefull the data is. That is also the issue with some of the tuning software that I have been looking at.
 
Lazaris i belive you are right,They call the a "K" type thermocuopler

More information please!

Probe in picture looks just like mine. If so, it's a "K" type Computech Systems, Inc. (301-870-8383) Clamp-On Themocouple (item 4015). Still works as good as the day I got it. Bought in 1997 so hopefully the phone number is still good.
