It has been a real eye opener for me.

Review: Koso X2 Boost/Temp/AFR Gauge
- Thread starter christopher
- Start date
Some photos of the gauge today
#1
Showing starting temp at 32 degrees, and AFR runing SUPER rich while the sled is COLD at 10.1
#3
Starting to warm up just a bit, and the AFR went even richer for a moment.
#4
Water temp now 69 and AFR leaning out to 12.3
#5
Temp to 70 degrees and AFR continuing to lean out.

Wow! I thought mine got rich when it was cold. Mine sits in the low 11 range when it is first started. Maybe just different with the supercharger or something.
Beats me.
Sure doesn't last long though.
I could sit there and watch the numbers start climbing just as soon as there was a hint of warm water flowing through the engine.

Did you mean that the large main display can display boost , water temp or the AFR? Or are they always in the same positions like your pictures?
YOU get to choose what is displayed in the main area.
I just FAILED to get pictures with the different data in the main box.
Pressing the large button on the bottom right scrolls the display.

Christopher,
Where did you get the mounting bracket and was that the right location? Where did you mount the afr bung and run the wiring?

seems like there was a bracket that came with it I was able to adapt and use.
Does the X2 gauge do a sensor warmup cycle to read AFR?
I always hated that about my KOSO AFR gauge, but love that feature about the AEM gauge!

If it did, I was certainly not aware of it.
If it did, you would know! lol
It reads Hxx while it heating up and usually takes 15-30 sec before it will display AFR!

I suppose its possible I just never paid that much attention right after a cold start on the sled.
But I sure don't remember there ever being a noticeable delay.
