X4 is nothing special, just 4ch ignitor...---------- Post added at 09:39 AM ---------- 6 hour anti-bump limit - Previous post was at 08:52 AM ----------waa... cannot say like that.. it not a waste, mybe it a must for certain engine.. the new tech been make is a improvement for older tech... why need improvement, coz old tech still have problem and cannot support in certain condition ...wasted spark have 2 spark ... 1="ignite spark" 2="waste spark" (this is suppose not to ignite)when it spark ??-1st spark = ignite spark = spark 5~45'BTDC at compress stroke -2nd spark =waste spark = spark 15~55'ABDC at exhaust strokewhat the prob with this sistem??-the prob is the second spark "waste spark"why 2nd spark "waste spark" prob??-coz it spark it exhaust stroke... normally it not a prob coz no fuel at exhaust stroke, so no explotion or ignition happen.. so it fire for nothing & it a waste ...- but we need to know, at exhaust stroke... valve overlap start to happen.. it will communicate the air fuel mixture & exhaust.... the communication of exhaust stroke & intake stroke will make a prob to us with wasted spark system.. it will cause backfire to the intake system & exhaust system... intake system also go to crank case system... it will make more trouble to us...what will amplify backfire prob to happen ??- use wild cam.. for me, start with 280' duration (more overlap), i will use sequential ignition... - use of NOS- batch fuel injection ( injector inject fuel while engine do not want it, fuel will stay on valve) - hi overlap running at high rpmSome true story:-blow composite sump cover(steel sump no worry)(the explosion go to intake than go to crank case) -blow engine-back fire while starting (batch fuel + wasted spark + hi cam = easier to happen)-etcjust sharing some info... any wrong, please educate me... thanks</blockquote>
