anyone has any suggestions to a nice 4 channel EGT controller? what methods of attaching the probes to the turbo manifold (cast) runners do you suggest? can a clamp style be used in a high pressure and heat environment?

 

How bout an AEM 4-Channel K-Type Thermocouple Amplifier? As long as you have something that accepts an analog signal for logging; The sensors are much cheaper than RTD style sensors and have a larger heat range.

Not sure on mounting style but I do not think clamp style would be recommended or even available(on the k-type thermocouple).

 

i looked at that and the TC-4 by Innovative, the main issue is lack of monitoring. i am used watching EGTs on a display on the instrument panel on an aircraft and would like the same.
this is what i found so far

this is the sort of clamps we use on the lycoming engines

Nice looking kit there. If you are used to viewing your EGT's on a HUD than that one looks like a sound choice. The only draw back would be logging the info for tuning purposes.

As for the mounting clamps, AEM uses something similar for O2 sensors. I don't see any drawback to having it mounted in that manner. It's just aesthetic look and possible error of installation that i shy away from that approach. Welding on bungs would be clean and there is peace of mind not worrying about a clamp vibrating loose.

 

can those bungs be welded onto a cast manifold? will an AEM or the TC-4 unit be able to transmit and display the data on a TunerView, for example?

 

Yes they can be welded to cast manifolds. As for the Tunerview, so long as it has inputs for either serial connection or 0-5Vanalog connection, the data should be transferable and viewable

 

If it can output 0-5v references to the EMS then the TunerView can use that information.

 

thank you, as we discussed elsewhere, i'll just make my own amp.

 

AEM now sells them with amp built in
