Removed stock gauges, need help

[1Slow90coupe]

I converted over to the autometer set up from Florida 5.0. It is excellent! Some of the guys at work said that since I removed the engine temp sending unit and replaced it with a mechanical one and now no signal goes to the ECU that it may cause problems. Is this true?

No.

+1 for the NO!!!

They were syaing something about it being stuck in closed loop until it warms up. What is that?

1slow90coupe: how much did it run, pics, which gauges did you get?

After I get my engine built I will go to their gauges

The ECT sensor has absolutely nothing to do with the temperature gauge. They are different animals. The ECT sensor is normally located it the RH front of the engine in the water feed tubes for the heater.

Trying to figure out how to compress the pics. I will post some in a minute

 

[1Slow90coupe]

How do you compress them. I can e-mail to you. 2 at 1.4 m each. I know it automatically compresses when I email them

Mechanical water temp sending unit

I am also installing new auto meter guages, carbon fiber, in my rebuilt 5.0 I will tee the oil pressure with copper tubing with the stock sending unit. On the water temp sending unit I was wondering the same thing. Your saying that the sending unit that goes into the lower intake will not affect the computer? I hope so as I would like to have the guages installed before i get the motor in and running. Just leave the factory wire disconnected? Should I change the ECT sensor, it is orginal with over 125,000 miles? I purchased a new ACT sensor, maybe I should change this also.

1slow90coupe, I.m sure your dash looks great with the Florida50 guages.good luck with your car!!
Thanks,

Not to get off track too much but I did the same swap on my wifes car. Did you get the alternator to charge the battery when you took out the stock gauge cluster?That took me a few minutes to figure out.

The gauge has a one-wire sending unit located in the lower intake just behind the dizzy. This is what is just for the gauge. You could remove the sender and insulate the stock sending unit wire if you desired. Then just add your new gauge's sender. FWIW, dont put a tee on temp gauges (that sounds fine for your OP gauge though).

Your call on replacing the ECT. JRichker has a list of thermistor values for the ECT at various temps if you desire testing its calibration.

Good luck.

I did not have any charging problems. I followed the instructions Florida 5.0 provided and all is well. They are excellent fit and look great.
