Datsun Roadster Kal Equipment Exhaust Gas Analyzer

The cost of putting your performance R16 or U20 on a car dyno can be well over $100.00 per hour. Having a load on your engine to precisely tune your carburetors has always been the best test. Here is a well built accurate, portable analyzer. Light use by owner. 

Use while you drive to monitor your air/fuel ratio under load. Just slip the probe into your tailpipe. Powers off your cars battery. Sit in the car and monitor you fuel ratio. Great if at the track and in areas where an altitude change affects the performance. If you have a Solex/Mikuni, car get the jetting right where you want it.
