correct value for warm CHT reading (ohms) Options

[brant]

so my CHT reading was 76 ohms - hot (at 180F oil temp)
I'm reading 2 different things.. on the Brad anders site


one saying that a warm reading should be below 100 ohms
but then the table shows this: for 210F

Sensor Temp = 39 deg. F Temp = 61 deg. F Temp = 210 deg F

0 280 130 003 6.10 K ohms 2.94 K ohms 199.3 ohms
0 280 130 012 NA 2.85 K ohms 191.2 ohms
0 280 130 017 3.63 K ohms 1.74 K ohms 124.7 ohms



I'd love some input from Djet folks about what numbers you see on a warm motor?

James,

super glad for your input.

I may be chasing nothing.
my plugs look a bit lean
and so far everything is testing spot on
car actually drove great (to santa fe and back to colorado for the RT66)

but my CHT gauge quit working and I pulled the thermo coupler to check it at the event.
noticed that plug was a bit lean... so pulled the other plugs and they are all the same.

I'm going to put the Innovate on it today and see what the actual AFR's are running at warm...

I'm guessing I might have to re-tune the MPS
however, it tested great last night and I see no reason for the car getting "leaner" as the plugs showed.

I will see what the AFR's look like
just seemed like the most likely thing could be a failing CHT sender... but it tests good hot and cold so maybe not....
