Scanmaster 2.1
1986-1987 Turbo Regal – SCANMASTER 2.1 – DIAGNOSTIC TOOL Application fits all 1986-1987 Turbo Regals and works with ANY computer chip in normal modes. This Scanmaster 2.1 was developed by Modern Musclecar several years ago and has proven to be one of the best tools for tuning your Buick turbo engine. It has a simple three-wire hookup. One wire to ground, one to power and one to the ALDL connector. The actual size of the Scanmaster is 4″ long for 2-1/2″ deep by 1″ tall. Ideally, it can be mounted on top of your dash (like in this photo), so it is in clear view. Each unit comes complete with easy-to-follow instructions. Also a reference chart giving you the display codes and the range value. The features include not only the 02 millivolts and degrees of knock re**rd, but also air flow in grams, LV8 engine load value, battery voltage, integrator, block learn, mph, engine coolant temperature, air temperature, revolutions per minute, throttle position sensor volts, idle air control position, and malfunction codes. With these features, it is very easy to properly tune your engine, even for the novice. By showing a digital readout of knock re**rd, you can clearly see if you have a problem. The air fuel ratio is also an important feature you can see with this tool. By watching the knock re**rd, you can determine how much boost you can safely run. When purchasing this part you may also want to consider part #7496. This is one of the most popular tools to properly tune your car. A must for your toolbox!
