Thermostat - ZR-1 Net Registry Forums

I am currently running factory thermostat - most likely 195.
I am thinking 180 plus a custom chip.
Any recommendation for thermostat?

Also, anyone with chip and lower temp thermostat - what operating temp can I expect?

What normal operating temperature do you see now? (with stock thermostat and stock? chip)

I have a Haibeck BMCBG3 chip for a 94 Z you can try out.

Here is the discription from Haibeck's website:

The calibration generally increases torque and horsepower by 10 respectively. It also reduces power fadeout associated with engine compartment heat. The engine will be more powerful and the output will be more consistent as the engine thoroughly warms up.
The original equipment calibration is designed to protect the engine when 87 octane regular grade fuel is used. This calibration optimizes the knock control for fuel with 91 octane or more. Premium grade fuel is required.
- The ignition spark advance is increased 10% at all engine speeds. As a result, the advance at wide open throttle is increased by 3 over the stock calibration to 28 degrees.
- Both of the cooling fans are turned on at 205 degrees. Both turn off at 200 degrees.
- The fuel delivery at wide open throttle is about 6% rich in the stock calibration. The fueling is reduced by 3%.
- The stock calibration retards the ignition spark advance when the intake air temperature is over 90 degrees F. This is revised to 160 degrees and the amount of retard is decreased.
- The stock calibration tends to falsely detect ignition spark knock on shifts at over 6000 rpm. This can result in a 10 hp power reduction for about a second in the next gear. The effect of these false knocks is reduced by 50%.
- The CAGS (1 to 4 shift) is disabled.
- The power key mode default is On.

Yeas. I would like to try it out.
Actually I called him and discussed his chip today.
Joy of having another 94 near by!

I will call and arrange something on Monday. I have your number from last time you called.
