Anyone have SPA gauges?

I just got 3 SPA dual gauges. Fuel press/water temp, oil press/oil temp and dual EGT. Had some issues with the water temp messing up before but it hasn't been lately, and in the manual it says that all sensors must be grounded. Not sure how I'm going to do that with the water temp sensor mounted in a t-fitting between two pieces of hose, unless I mount it in the stock location haha. I think I might just do that anyway, and see if the stock sensor can mount where I have the aftermarket sensor right now.

Anyway, this is more about the issue with the EGT gauge. I'm using TSC sensors that are supposed to be quick reacting. I'd like to keep using them but I guess I'll switch to the sensors that came with the gauge if I have to. Anyway, I took the thermocouple connectors off the SPA sensor wires and put them on the TSC wires (yellow-positive, red-negative). When I turned it on, the EG temps were around 150*F, and as I drove the car it only got lower. I figured maybe SPA wanted the wires hooked up the other way so I switched them, and then I got a reading of -86*F haha. So that's not it. I'm going to look into the TSC sensors (I believe they're K type but I could be wrong) and the SPA sensors (which I believe are K type as well). They're both 2-wire sensors, I'm just not sure why they're not working.

I just looked on their site and it says the temp is limited to 1000*C, which is 1832*F, but IIRC that is because of the sensors and not the gauge. Although the gauge reads 4 digits but it's set up as 000.0 and not 0000, so I'll have to see if there is a way to push the decimal to the right one spot.

Anyone have any input?
