K.A.T. Matrix 3-Axis Car Performance Accelerometer

• Three-axis sensors for no-compromise accuracy
• Displays 0 to 1/4 mile time and speed, and 0-60 MPH time
• Battery operated for convenient use in multiple vehicles
• Micro-electronic design allows batteries to last up to one year
• Extra large back-lit LCD display with 1/2 inch numbers for easy, safe reading while in operation

The K.A.T. Matrix is a nice unit for a small amount of cash. Some of the setup is a little difficult to figure out, but even fresh out of the box it can be used with little setup to give a base 1/4 mile and 0-60 time for a reference to see what exactly tune ups and after market parts do for your vehicle.

It works as expected, shows the G-forces. But...

It does not show the peak, which is a big issue. When I am driving I am going to be looking at the road and not at the meter and it is continuously changing so doesn't make sense to to store and display peak values later. If I would have known this I would not have bought this. I thought it would be a given, who is going to be looking at this continuously when driving and to what purpose.

the other issue is cheap build quality, the right buttons are sticky and don't function well.

Overall a cheap product with limited functionality.

I bought this because I just bought a 1972 Monte Carlo with a 350 sb, all original and wanted to see what she would do. The local 1/4 mile strip closed down recently and there is no others within a 5 hour drive. The price of this would cost the same as gas. It does 0-60 time, 1/4 mile time AND speed and G forces as you are turning, accelerating, and stopping. You cannot do all 3 at the same time, it is one setting at a time. You follow the directions to put in the weight of the car and driver and the testing parameters(range of miles per hour, e.g.: 30-70 mph) and it will give you an estimated wheel horsepower within the parameters which is pretty cool. The mount has 3 suction cups to hold to the windshield securely. The time and speed are consistent. My best time is 14.7 @ 103 mph with a max HP of 225 at the wheel. Statistically, it is correct and the numbers all match. If the track opens up, I will test it on the strip. Alibaba.com wholesales this for about $20 a piece but you have to buy 18 at a time. Might be a good investment. I bought this from Amazon for $58 and they have sales every once in a while so look for that.

I am very satisfied with it. I have used it several times now. I would say it is pretty sensitive to the movement, speed and g force. For the price I got this, believe me, it is worth the money. I am pretty happy about it.

I am also very satisfied with the instruction and how simple is to use it. It is not a complicated device you will be spending/waisting time to find out how it works. I also appreciate the fact that it is cordless and can be used on any car as needed. Very practical.
