The 511N timing advance processor (TAP) adjusts the spark advance angle when the duel
fuel ( petrol-gas) vehicle uses different fuels, so as to ensure the engine works under the
optimal spark advance angle at different speeds. It can run on duel fuel at a more optimal
state without changing the compression ratio and combustion structure of the original engine.
It can be installed on 3,4,5,6 and 8 cylinder cars fitted with an injection-ignition system with
an inductive CKP sensor type. It can automatically adjust the advance timing, improve
performance, reduce consumptions and the risk of "backfiring".
