Anyone know Holley Commander 950's? programming?

You can save about $50 without the gauge. You can still read it via the PC. The wideband O2 are expensive due to the electronics that feeds the sensor, they have dropped. Still 10x cheaper than the 5 gas analyzer I purchased years ago.


Good luck! Looking forward to your progress and a great running car. Tunning is a matter of divide and conquer. It is necessary to identify the operating conditions, and make the changes with the correct means of adjustments.
