A knocking control system for an I.C.E. includes a knock detector, and an apparatus for retarding the timing in response to the detection of knocking. This apparatus includes an arithmetic device and a memory map for storing retard values and accessed according to intake pressure (engine load) and r.p.m. values. The map value is read out by the arithmetic means is generally corrected on the basis of the present knock value, and the corrected retard value is used to control ignition and may be stored in the memory map to replace the read out value.
