    Hey nitrous1, if you do get the RPM to work PLEASE see if there is any setting that can be done w/o the TECH2. I tried by adding the correct value to the override option, but nothing comes up for RPM.

    Let us know how it goes. You'll be praised by many if you get it to work Me included.

    Re: How do I get the Temp reading?

    I have the same problem, I have a 95 Deville with the digital cluster, everywhere I've read say's I should have the Engine Temp and Rpm's in the info button/reading... But I dont, I have ave. mpg, trip, oil life etc. If these should be on there and the previous owner(s) somehow removed them would disconnecting the battery reset them? Anyone else have a deville ODB1 with my same problem?

    I have the same situation in my Councour 1994!

    Can I show the temp and the RPM on my digital dashboard?

    Thank you for any suggestions.

    Just wondering on a 1996 Deville can I override the computer to have the cooling fans turn on 5-10 deg earlier?

    I don't think so unless you reverse engineered and re-programed the PCM.

    But why do you want to do this? There are hundreds of thousands of Northstar engines running just fine the way they are.

    If you think something is wrong then you probably have some sort of mechanical or electrical problem which if fixed will make the car work right again.

    Or do you have another reason for trying this?

    Re: How do I get the Temp reading?

    I have found that once the temp reaches 245-250 or so in my N*, the cooling system cannot right itself and the car will overheat. This does not happen often but after a few WOT on the highway with speeds reaching 95-100mph I have to keep a eye on the temp or I will exceed my point of no return and the car will have to limp home or pull over to cool off. I am sure I have a internal coolant leak as I have to add 1/2 gallon of antifreeze a week in the car. I use the bars leaks and am saving my pennies for the timesert job. If I could have my cooling fans come on a few degrees earlier it may help to keep the temps in a lower range. The radiator in my vehicle appears to be in good condition and I have replaced the water pump and lubed the pulley pivot point. I can putt around in this car all day long with no problems but I like to feel the performance these motors have from time to time.

    It's doubtful having the fans come on any sooner will help anything. As you describe your speed when this is happening, there is already plenty of airflow and the fans aren't contributing anything. If the water pump is good, the problem is more likely a radiator issue or internal waterflow within the engine.

    Hi everybody,

    I didn't receive anything about the above problem with my Councours 1994!

    Can I show the temp and the RPM on my digital cluster?

    Thank you for any suggestions.
