An adaptive control system for an internal combustion engine has a mixture control device and an ignition timing control device. Combustion performance, such as engine roughness is measured and mixture varied about a base value to achieve a desired performance. Ignition timing is compensated for the mixture variation by perturbing ignition timing about a base valve, detecting the slope of engine output with respect to ignition timing and varying the timing to achieve a desired slope.
