The ultimate in tachometers for street or competition. Works on 4-6-8 cylinder by following the instructions. These are the best you can get for a high performance VW. They respond quickly and are extremely accurate through the entire RPM range. More accurate in the top end scale (5,500 to 10,000) than any other brand we have tested, and I have tested just about everything. Made in the USA. Pro control is designed for use as a shift light or a rev limiter. It cannot be used for starting line RPM control. The rev limiting is designed to shut the engine off at a safe RPM well above your normal shift point to protect the engine if you miss a shift or brake a trans. If you hit the rev limiter every time you shift you will damage the rod bearings and must be shifted sooner or set higher, do not use it to determine when to shift. Works with all Stinger ignitions by following the instructions that come with it for standard ignitions with or without the resistor. Warning: Many people that use Soft Touch or 2 step rev control experience premature rod bearing wear, broken rings, cracked cranks, broken cylinders, etc. This is caused by the loading and unloading when the ignition is turned on and off without load or voltage being reduced. I would never recommend using any such device. |
