The car I bought a little while ago had a 3.2 in it with stock FI and engine mgmt. That includes a CHT for the computer. At the last minute, the selling agent I was buying the car from decided to put in a center console with a CHT gauge. He did not have anything to drive the gauge so they hooked up a real fast solution just to get the gauge running. See the pic...
The problem is that where and how it is located, it pretty much just reads 0 or 350, nothing else. It never reads lower, never cools off. It is right by the exhaust manifold. The 3.2 has a built in CHT. Can I buy a new temp ring and tie it in under the factory CHT on cyl 3 like the factory? Is there room under the plugs on a 3.2 for the CHT ring like it would be hooked up on a 4 cyl? I have not looked into the plug area to see if there is any room. I don't think I can split the output of the factory CHT or it will change the resistance, I am guessing. What have others done to feed a CHT gauge on a 3.2?  |

Is there a benefit to running a CHT and Oil temp on a six? I've always just seen oil temp as the main unit to monitor. Try to keep the oil temp under 210f on the regular, but I think up to 240 is ok.
I guess it would catch if you were running lean but the oil system was still able to keep you cool? |
