RARE J&S Knock Safe Individual cylinder Ignition Timing Retard System
As the OE toyota knock system is very slow and outdated, this piggy back unit allows you to turn up the boost to ridiculous amounts and the knocksafe ecu will retard timing for each INDIVIDUAL cylinder when it detects pinging so that the motor does not knock/detonate.
Great for those pushing on the edge with boost.
Saved my motor plenty of times(bad gas, overboosting). (Pushing 18-23psi+ on a stock gen3 ecu and tuned mines ecu / stock motor with turbo kit for perspective.)
