The diesel Tiny Tach sold here is http://www.tinytach.com/tinytach/diesel.php is superb, They have updated the design and it no longer uses an internal battery, it uses 12V power, and updates much more frequently than previously.

The 6mm transducer is the correct one for our vehicles,

I cant recommend this product highly enough, its superb. If you need a tach for your 240D this is it.


Check out my comming diesel SEC buildup thread for pics of it in action.
