About Using OBD Products in Combination
If you wish to use PT6 in combination with products in our 3-drive Series or other OBD products, the "OBD2 Wiring Kit OBD-EH" (sold separately) makes installation a snap.For
more details about using combinations of products see here. ⇒
Note: When using PT6 with products mentioned above, they can only be used together in compatible model vehicles for both products.

When connecting the RPM signal to the
ignition coil or diagnosis and the indicated
rpm on the meter may be obviously lower than
the actual rpm as shown on tachometer.
e.g.) For a 6 cylinder car, the reading should be
3000 rpm, but display shows 500 rpm.
This may be caused by the individual wiring system
of that model of car. Change the cylinder setting to
"1". (See page 3
