It seems as though every time we turn around, there's a new performance measuring tool for us number-crunching bench racers. In previous issues, we've looked at the G-Tech Pro Competition meter as well as the Escort G-Timer GT2. This month, the MR Dyno from Midnight Research landed on my desk, and I have to say what it lacks in external design, it more than makes up for with its fully featured functionality.

The MR Dyno retails for $125 (which includes a PC cable and a car power adapter) through the MR Dyno Web site. The unit has the ability to measure and record all the standard values of other performance computers, including eighth- and quarter-mile times, 60-foot times, g-forces, deceleration and braking tests, 0-60 times, and more. The MR Dyno meter's memory allows a whopping 50-run capacity (and can store 10 separate vehicles), so you can make several runs during performance tuning or parts swapping, then look at the runs later. The included software allows graph analysis of each run, with room to enter notes (i.e. "changed timing to 18 degrees") and the ability to compare runs and print the information.

One of the best features of the MR Dyno is the unit's correction ability. The meter has calibration screens for weather-condition corrections (such as temperature, humidity, and altitude), performance-loss curve, acceleration-tilt compensation, and more. The unit even features a live streaming option to your PC laptop. The only points we'd deduct would be for a steep learning curve and for the often cryptic LED display, both of which are easily overcome with some hands-on time and familiarity with the unit.
