I need to know the catalog number for the digital compression tester.

Also, What is the difference between Mazda Rotary Digital Compression tester vs. Piston Digital Compression tester from Mazda.

I'm about to get one but not 100%. It looks just like the one Rich (GoodfellaFD3S) posted few days ago.

Special Tool section of the manual says: part number 49 F018 901

One I'm looking at has part number: 49 H075 280

Thanks!

GoodfellaFD3S's compression tester

 

One that andre sinclair was selling awhile back.



I just don't see any other car will use 3 display like the rotary ones..

 

Just confirmed thru one of the rotary enging builder that ones I have are infact Mazda Digital compression tester.
