Default Holley computer and obd2 inspection

What do people do that are running the Holley computers in a street car than need to pass inspection? Are there provisions in the Holley for setting monitors or do you need the stock computer

May just want to drop Holley a line and ask them. Probably be quicker.

There is no provision to make obd2 output. No aftermarket stand alone has this.

Correct, they aren't coded for OBDII in aftermarket ECU's as they do not operate the emissions controls. Factory PCM would need to remain in place for that function.

They are using pre-1996 cars.

Or they are registering the car in an area with no inspection/emissions.

Or they are running on a dealer plate.

if you MUST pass the plug in obd2 test you can leave a stock ecu in the car as a slave.

Yup, just needs to see a power, and tach signal.
