I've got some variety of this one. It cycles through multiples of the actual rpm that applies. Take an educated guess. There are a couple of buttons to push but they don't seem to do anything. It's ok if you don't mind playing its silly games. I wouldn't buy it again.

If you are using it on small single cylinder 4 cycle engines like lawnmowers, wood splitters, etc. it doesn't matter because they spark at TDC every time, just like 2 cycle engines. It gets more complex with multi-cylinder engines. Most tachs can toggle through different settings to give an accurate reading for a particular engine. The cheap Chinese-made tachs on Amazon/ebay are supposed to, but may not due to faulty cheap construction and lack of good instructions on how to get them to toggle.
The Stihl EDT 9 tach you mentioned is supposed to do 2 and 4 cycle engines and twin cylinder engines according to the info I found.
Some of the tachs on Amazon/ebay are cheaply made lookalike copies of quality made tachs that do work properly. Beware.

4 cycles spark at TDC on the exhaust stroke? Learn something every day.

Stands up to reason reviewing the spark generating flow chart/schematic.

Plus, you can get a neat little holder for it.

Wish they weren't so expensive I'm tired of the cheapies that I have. Lol

Some things are just worth it I guess, the pinch from purchase will fade away after the first use.

Once you have one, it's near uncivilized to be without.

4 cycle just like two stroke they fire evert time the flywheel magnet passes the coil.
Cylinder does not inite, on the exhaust stroke. You only need to change readings for more than multiple cylinders.

Attached are detailed instructions on the EDT 9 Tach. Most flywheel magneto 4 strokes have a waste spark on the exhaust stroke, so the default setting on the EDT 9 works for both 2 stroke and 4 stroke magneto small engines.

I've been using my handheld Electronic Specialties unit for a few years now and it works great. Now, the refresh rate isn't very fast, if that matters to you. I accidentally pulled apart the inductive pickup and ES sent me a new one at no charge. I also have one of their multimeters and it works great also.
