I have Defi guages and the Defi EGT probe which is notoriously slow, is now really slow; This is after about 20k miles of use.

What is the best probe to replace the original probe with and what are the correct part numbers needed?

Thanks in advance

 

the orignal prob is the best they cost about $175.00. But I have one with a little less than 1000 miles on it well its a defi gauge and defi probe for 150.00 plus paypal fees let me know

 

I have heard Zeitronix is compatible and superior to Defi's probe - any feedback on that?

 

Almost all EGT gauges use K type thermocouple. The difference is in the probe construction, mass etc. Some are better some then others. This is why we give you Zt-2 style 2 pin EGT connector so you can retrofit your own EGT probe. You do not have to buy one from us. Wonder if it works the other way arround?

 

Zeitronix-
Can you PM a list and prices of the necessary components? I'm inclined to give it a try.

 

There are Zeitronix vendors on this board. Contact them.

 

Z - when you say retrofit, can you be more specific? I now have the EGT probe and neither connector will fit. Am I supposed to splice the wires?

 

Most EGT gauges use K type thermocouple probe. All probes have different connectors so you need to splice wires if you are using X manufacture probe with Y manufacture gauge. Of course Zeitronix probes plug right into Zt-2s. We also give you a 2 pin EGT connector to retrofit your probe when connecting to the Zt-2.
Keep in mind EGT probes are polarized.

 

Thanks - do you know which wire on the Defi is positive and which is negative?

 

I had the same problem but i got a egt sensor for like 85 buxs let me know i also have one for sale.
