5.0 out of 5 stars Works well, August 16, 2009

This review is from: Electronic Specialties 325 EZ-Tach Digital Automotive Tachometer (Automotive)

I used this to provide RPM data while rejetting and fine tuning the carburetors on my motorcycle. It worked well and seems to have a decent build quality. Make sure to clamp the tool on the plug wire in the right direction, know if you are testing a two or four stroke engine, and know something about how many spark pulses are sent per engine cycle.

3.0 out of 5 stars Automotive Tach Only!, January 4, 2009

I bought this unit to adjust the idle/maximum RPM on various outdoor power equipment with small engines. When I connected it up to a snow blower, the readings were very erratic. I decided to try the unit on my car. It worked fine in that application, displaying the same value as the tachometer on the dash.

On the package, there's a sticker saying Automotive Use Only and that Model 321 should be used for small engines. I wish that information was prominently displayed in the online description. The description says 'any automotive engine with a spark plug wire' which I interpreted as any 4 cycle gasoline powered engine.

BTW, the model 321 is 3 times the price.

This tach works pretty good, only drawback is it is directional. Sometimes that puts the display on the back side and makes it hard to read. But overall, a nice tool.
