jyri,

I answered almost the same question yesterday in this thread:

Unless you have considerable electronics experience, and a test bench with a variable power supply and some test equipment, including an oscilloscope, frequency counter, and variable pulse generator ... leave it to professionals. It is probably a simple procedure which could involve moving a jumper/strap or adjusting a trimpot, or both, but it should not be attempted unless you are equipped to do the job as stated above, so you can accurately calibrate the tach.
