    idle spark timing fluctuation after cam swap

    I have 2013 2500HD GMC SIERRA 6.0 (L96 Engine) with E78 ECM (Torque base). I swapped camshaft to 226/231 113+4.

    I tried to adjust the virtual torque raise the idle spark but no benefit, the spark is not constant

    Can you please see these tables and tell me what is the wrong?
