How Do I?


Jul 26, 2010
I believe my National has no chip, Where would i look to find out if my car has a aftermarket or stock chip installed?
Second I'm going to purchase a scanmaster which one would i be looking to purchase, What is the recommended unit?
Lastly depending on my chip status, (stock or aftermarket) what settings would i need to dial the scanmaster in? Or do i have to not dial in settings?
Please and Thanx for all your time.
the chip is in the computer which is in the front right side kick panel just under the glove box. the Computer has a service panel with 2 screws pull the that panel and check the chip for any markings.

Scanmaster 2.1 i think is the "New" one, you just plug it in and go
