Hey guys, i recently got myself a jzx100 mark 2 and decides to do minor service on my car. I bought 6 spark plugs from supercheap and happens to me that the 1jzgte vvti is running a called wasted spark ignition system. and i was like wt*... i did a few hour research on the internet goggling every information about it and turn out nothing appreciable. SO my question will be do i need only 3 spark plugs to power the 1jzgte vvti or i still need 6? Cheers

Someone may be able to correct me, but my limited knowledge on Wasted Spark is that basically it would have 3 coils that each fire 2 plugs at the same time?

Exactly.

Wasted spark just means two plugs fire at the same time, one during the compression stroke and one during the exhaust stroke. The one during the exhaust stroke does nothing, hence wasted.

hmm, i really dont mean to be a prick man, but...

if you somehow thought that there might be the slightest possibility of your 6 cyl. engine only needing 3 spark plugs... well lets just say if i were you i'd have someone show you how to do it for your first time that is all...

other wise your next post may be something a little more embarrassing/severe

Thanks,

Trent

thanks mate its just so different with the 1jzgte vvti... have more to learn.

Nah your alright mate, i pull it out slowly today and found 6 plugs, it just so different the coil in 1jzgte vvti... if you have seen them before you know what i said. but cheers anyway for the cautious.

    • Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).
    • Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers    
    • Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
    • Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
    • Hi All, putting the engine back together and everything is perfect except have this plug left over.. any ideas what it is for and where it goes? Is on cold side under the intake plenum *note not a stock plug, as everything has been modified Cheers
