Where is my fan temperature setting?
Probably this is a dumb question but I can't find the temperature setting for my fan.
I've downloaded the bin from my IC and xdf I'm using is JP's 61 v2.
I've been through all the Constants (and Tables too) but I can't find it. Am I that stupid (OK, you don't have to answer this question)?

Sorry, my mistake for not explaining this very well. I'm looking for the Temperature Fan Constants in the PROM not the fan sensor.
I'm modifying my PROM using TunerPro and I can't find the constants the set the Fan On an Fan Off temperatures.

Are you using a stock 91 TBI ecm? If yes... re-read the folowing:
As far as I know the ecm has no control over the fan. The fan switch in the cylinder head grounds the fan relay coil at a certain temperature (stock is 220F).

Hi im a newbe in tuning the ecm, but I know there is a way the ecm controls the fans, because I have seen someone change the on/off in there ecm but dont know the codes. Im going to have to find out myself also.

For the TBI, no, the ECM does not control the fan, the switch in the passenger side head between 6 & 8 does.

Oh well, I was hoping I could do it via ECM.
Is there a sensor that would reduce the temp to 170F?
DM91RS, what's EBL?

Sort of, I think Jet makes them. Summit is a distributor of these fan switches. Temps I know of are:
220 on; 200 off
200 on; 185 off
180 on; 165 off
