question, about OE CHT sensor Options

[bd1308]

now that i have carbs, i have no use for my CHT....is there any way to get a CHT guage to work with the stock sensor rather than having to buy a setup........

the CHT sender goes under sparkplug #3, not in the stock place... the stock sender is like a switch... it reads "hot" or "not" and that's about it... a CHT gauge and sender kit is pretty accurate... but needs to be in the right spot, under the #3 plug.

If you go to the Megasquirt site and do some google searches, you can find the conversion charts for the Bosch CHT sensors.

I am using a stock CHT with my aftermarket FI, normal operating temp that would shut off extra fuel on a D-jet is a CHT of I think 300°, my laptop reads it as 180° (the stock CHT has the same resistance curve as a Chevy or water cooled Bosch sensor)


The CHT has a curve so you could heat it up and measure and plot the curve.

only problem is is that the temperature is really only relevant to you and your setup, you cannot compare your numbers to anyone elses unless they are running the same combo/calibration.

if you just want to see the temperature change, you could use a Chevy or possibly a german water cooled temp. gauge
