My preference is aways to do steady state mapping on the dyno then refine the transient calibration on the road. Unless your engine is det limited everywhere I dont see how you can calibrate ignition (well anyway)
I agree with Stav that knock control is not neccassary, I have run without it for 4 years on my race car (205 sr20det & self mapped MI16) in temperatures from -5 into the 25-30's. Its just calibrated well the Rb30 Sc will also run without it.
If you understood what was neccassary to calibrate knock control to work well on a production car you would realise its a waste of time on a race/ high performance car. Half the time it will be taking out ignition when there no knock because the systems are so basic.
