I have a 180 or 185 thermostat and had the fitech sensor in the thermostat housing and it never got over 170. I never removed it from the housing when I got the Delco. Because my intake doesn't have a hole for a 3/8 sensor I wound up installing the Delco sensor in the heater hose at the back of the block. My normal running coolant temp taken at that location according to my handheld controller is between 190 and 201 but cylinder head temp shows 140-143. I'm not sure how they come up with that number.
I kind of wish that Austin Dehaas guy who has that fitchtuning website lived near me so I could just pay him to tune it for me.
It will be 2 weeks before I have a mileage number for mine but I was getting a consistent 9 MPG with the carb. I hope you figure out how to get better mileage so I can do the same.
Yeah I see it now lol. Does it make sense that the cylinder temp is colder than the coolant temp? Not to me. I thought that was what it was reading as my running temperature . I’ll compare it to my analog gauge today to see if it’s on or close to the fitech sensor.
All I noticed different between yours and mine was your afr was 1 point set lower and your pump pwm was 2 points higher. I don’t look at it too long. I do t know what it means. Your un a 6cyl right? I haven’t tried to lower my afr settings since I reset everything after I installed a new o2 sensor thinking it wasn’t t working correctly and it didn’t help either. Was going to do so when I figure out or find something to set it too. Need to break out the manual again to remember how it works.
That guy won’t reply to my post for some reason...
