The title is the question.
I know what to look for with water-cooled stuff. I have no experience with air-cooled stuff yet... What say you? Is there a normal range? A never exceed number? Anyone ever use 4 thermocouples? Was there any noticeable difference (#3 is of concern to me)? Thoughts, tips, any data would be greatly appreciated! |

QUOTE(VaccaRabite @ Jan 10 2024, 10:21 AM)  Something to consider... Microsquirt (which uses an MSII ecu) only used the CHT for warmup purposes. Infact we hijacked the coolant temp sensor pin (CLT) on the Microsquirt ECU. For the CHT/CLT we used the stock location, not a spark plug. This mean that my CHT gauge read a bit higher then what the ECU saw. Which was fine, I just set my warmup enrichment and AAR tables for the ECU and had to divorce myself from what I was seeing in the cockpit gauge. The new engine running Holley Teminator X is doing the same thing. Using the stock location for the CHT for warmup, and then I monitor the "real" CHT in the cabin with the DD CHT gauge using a K type on Cyl 3. With the 4 Way you are getting, if you are using it for CHT you will need to do the same thing, as you won't have another spark plug you can put a K-type thermocouple on. Zach Yep, figured as much. Update on the rooster! Critter got out during his attack. Was on the top of the coop last night, crowing his head off! Anytime anything moved in the yard he'd crow. 3 am, you couldn't get within 75 feet of the cage without setting him off. Unless it was very cold... It was cold this morning when I went outside to deal with him. White feather bomb detonation! He'd met another critter! I didn't have to kill my wife's rooster. Karma is HUNGRY!

It must have been 1300 degrees I was remembering, not 1200. Still a little fatter than what others report ...
