To our customers and dealers,

The Bazzaz team would like to thank you for the many years of support and loyalty to our products.

As of 1/1/22 Bazzaz will no longer offer support for the Bazzaz engine management line (Z-Fi, Z-Fi TC, QS4, ZAFM).

Although YFI racing will not be offering technical support for Bazzaz products except for customers who purchased directly from YFI Racing, many QS4 kits, accessories, and spare parts will be available through them.

You can also contact YFI Racing at if you do not find what you are looking for on their site.

The Bazzaz website will remain to offer customers access to installation instructions, fuel map database, and technical support documents. The technical support documents utilize the same diagnosis steps that the Bazzaz technical support team has worked from since the beginning so they should be very helpful.

The Big Three: double-check these three common culprits:

  1. The Bazzaz ground lug is properly secured to a non-insulating chassis ground. Test this by temporarily grounding the Bazzaz ground lug directly to the battery negative terminal and checking to see if this resolves the issue.
  2. The vehicle has fuel and there are no obstructions (such as a fuel line kink) that could affect fuel delivery.
  3. The Bazzaz control unit powers up. Turn the key on and the control unit should illuminate blue. If it does not, re-check the 12V power source connection
