Hello,

After watching the process for tuning the fuel table via the AFR correction factor in the "Correcting your AFR" video, I'm wondering if it is possible to do this on the road, without a dyno? It seems to me that on the road, you'd only be able to hit one cell in each column since the RPM will increase if you open the throttle more to increase the manifold pressure. Am I missing a key idea here?

Thanks!!

You use Left Foot Braking to hold the engine speed steady and increase the load. Or go up a steeper hill..
