Thank you. It makes sense. I have this air/fuel mixture measuring system from Innovate Motorsports I purchased it years ago to tune the fuel injection in my BMW 2002tii, it has a sensor fixture that goes in the tailpipe and can connect to a computer. The thought of going down the road with this setup is not appealing. I guess I should look for a dyno. Cheers.
While not perfect, you could use it to ballpark your setup. My mechanic buddy used his, normally used for setting up racing motorcycles, to check mine. Checked at idle, checked at 2500 rpm. The jets/vents Dave set me up with were perfect, as was his “ear and unisyn” preliminary settings.
The hardest part is holding your engine at 2500rpm in the garage. It seemed like cruel and unusual punishment to the poor engine.
