SPA Dual Gauge Review

[Matt400]

I thought I would post on my findings with this product.

The SPA dual gauge can be had in many different configurations of which you can find here.
For me with my auto trans I chose to go with a Temp/Temp Gauge and configured it to read EGT on top and Trans Temp on the bottom, in the SRT-10 A-Pillar it looks like this:
A friend of mine chose the EGT/Boost gauge for his 6 speed truck and it his looks like this:

An interesting feature of these gauges is the multi function menu that you access with the red button.
You can download a complete user manual here or here are some highlights…

It has a 15 position adjustable back lighting of which you do not connect into your dimmer circuit. I found that with it on #2 in the dark it does not overpower the dash lights and yet is very readable. Leaving the back light on at all times with this setting provides a look of no back light in the day yet starts to gradually show as the sun goes down and by the time you switch on your headlamps it blends real well.
You can change the back light from red to green to off.

Units of measure can me changed
The warning lamps on the gauge can be set to flash at whatever measurement you like.
There is an external output on each that can drive an led for yet another user selected warning or a relay at what ever measurement you like.
It has a low battery warning built in so even though we are not talking about one of their volt gauges these will warn if battery voltage falls below a “user selectable” voltage.

Resolution is selectable if you would like to see for example 28.7 lbs of boost or just 28 lbs. In experimenting with this I found that low resolution is more easy to read because the numbers are not changing so fast.

A quick press of the red button shows the highest number attained, keep pressing for 5 seconds and it will clear so you can do unmonitored measurements for later review like gauging EGT’s at different fueling box settings on a course that requires more attention to the road.

You can get these in a chrome bezel, black bezel, white face, black face or any combination.

All the wiring, connectors, senders and such are included. These are pretty spendy but IMO are worth it for the unique features.

I hope someone will find this info useful…
