Review on 🚗 ESUPPORT Car 2" 52mm Turbo Boost Gauge Meter with Blue LED Light - PSI Pointer for Enhanced Performance by Chris Nako

I installed this in my 85 Dodge D150. The speedometer I received did not have the "Cylinder # Selector" shown in the pictures; It only had a button labeled "Install" on the back. Nothing in the instructions mentions an 'Install' button, so I'm not really looking forward to figuring out how it works. And I very much doubt this wheelbarrow has enough intelligence to automatically determine the number of cylinders, sooooo yes. The touch I received does not match the product description. It also came with a dial set at 4800rpm, I hope it resets to 0 after plugging in but I'm not really betting on it. I'll update my review once it's up - or not. UPDATE it really works! Once the voltage reached it, the scale dropped to 0 until the engine started. I believe it's only compatible with 4 or 8 cylinder engines, because if the 'set' button is pressed for 3 seconds, the dial jumps to 4,000 rpm. Or maybe it's really smart enough, to find out how many cylinders it works with? Hard to say. It seems pretty accurate. The blue backlight doesn't seem to work, but that's probably because my wiring was imprecise. My only complaint is that the kit did not include the screw on the back that is pictured in the dashboard installation guide. Otherwise an excellent value note.
