I am upgrading to the attitude and I currently have the spa 211.... I have read that the attitude thermal couple is smaller and reacts faster... Has anyone mounted the attitude thermo in the same hole as other guages using a bushing....


Stainless steel was recomended.... Does anyone know where i can order these... or have experience with this...





Thanks

YEA IM WONDERING THE SAME?>???? AND ALSO WHAT BOUT THE BRASS FITTINGS THAT ARE WITH THE ATTITUDE PYRO-------WILL THEY HOLD UP TO THE HEAT IF MOUNTED IN THE MANIFOLD??

currenty i'm using the thermocouple from my x-monitor (no longer needed) till i find a bushing at home depot?

Pep Boys and small auto parts houses usually have a case of bushings. I'm not sure if brass would be a problem. All the ones that come with pyros are steel.

It's not a Duramax, but when I raced go-karts, I used a brass bushing silver soldered onto the header pipe of my Yamaha to hold the pyrometer probe. EGTs there were in the 1300+ degrees F range. I never had a failure.

That may be the way to go.... If you do find one there let us know....

Please correct me if I am wrong... But i beleive the Attitude comes with a 1/8 npt thread and the SPA 211 has 1/4 npt......





So the bushing would be 1/4 to 1/8........

I purchased the bushing at a hardware store for 99 cents..... Brass was recomended by the metal specialist that I talked to because it will expand slowwer than iron... But he also said it may be harder to get out..... I plan to do the exchange this weekend... I will post the troubles......

IMHO, brass will work fine, methinks your pistons would melt first. I just re-installed an exh. system on a cherokee 150 using brass nuts(they don't rust) and am taking it to Savannah this weekend to pick up my daughter.

I don't know about automotive parts, but with aircraft EGT systems, the sending unit and the gauge are matched. Because of the different ratios of the material, and indeed there are more than one combination, and even the length of the leads, the resistance of the circuit can be affected if the components are not matched, so you'll get an erroneous reading.


Might be worth checking into before you mix and match components. Perhaps one of the other members has more info on whether or not this is a concern with the automotive equipment.

i have not seen much diff. in temp. readings, but i found my bushing and will install new thermocouple this week end and will report. i was told you can not cut the wire for the thermocouple, that will mess up the resistance, but they are not matched to the box, how would you get a new one if you needed one

Perhaps my use of the word "matched" was not a particularly good term. What I meant is that the guage and sending unit need to be designed to work together in order to account for the various lead lengths and the output of the sending unit.


So manufacturers will produce different sending units, usually the only difference is the lead length, and they will list a specific part number guage to go with that specific part number sending unit.


Since the whole principle is designed around the fact that heating a combination of certain materials produces a tiny electrical current which is read by the guage, any change in the resistance of that circuit changes the guage reading.


Changing to another manufacturers sending unit may also involve the use of a different material combination in the sending unit which would also cause an error due to the sending unit ouputting a different amount of current for a given temperature.


I was just concerned about you getting a bad reading that might cause an engine problem.


Glad you found your adapter. I've been following the posts on the Edge because I have a new truck coming and I've decided the Juice with the Attitude is the way to go. Only problem so far is that Edge has not been able to test one of the units on an LLY engine, which my truck will have. I've been in contact with them and they have a truck on order with the LLY, but no production date yet. So since they are just up the road from me, if mine shows up first we're going to try a unit on it.

Good luck with testing on the LLY..... I have completed my change from the spa 211 to the attitude and I cannot beleive how much faster the egt guage goes up.... I have already hit higher temps playing around doing 0 to 60 runs than I have towing with the spa up hill in the same level.... Kinda makes me nervous about the temps I was really running....
