Sarge can u hear it pinging? Does it happen on high boost?

What are the afr's doing?

Can't hear anything from the engine bay over the exhaust, the windows up doesn't help. Another thing that doesn't help is the fact that I cant make it happen every time. I can go to the same stretch of road where Ive pinged before, use the same gear, same start speed, same throttle and then no pinging. Its also hard to keep an eye on the AFR but on boost it goes down to about 12 and into the 11's. Ive tried to log it with the laptop but when I put the laptop down in the passenger seat and I drive over a bump in the road the USB cable comes jiggles and I lose connection. Really need someone in the passenger seat and a private stretch of road so I can test it out. Ive watched videos describing what ping would sound like. Some people say its the sound of metal chains dragging behind the car while some would bang a hammer on a piston and say that is what you will hear. Not sure what to make of it. Its not the easiest thing to fang second to redline and listen for ping in a skyline lol.

maybe not enough throttle enrichment? I had that issue when I smashed the pedal here and there, I added in more throttle enrichment and it went away (just from my personal experience)

Its got some throttle enrichment in there and when I do quick stabs at the throttle the afr richen up abit. Its not the stabs which cause the det, seems I can push the car from 2000 - 6000rpm but it gets into a danger zone at around 6400 rpm.

Take up Jez on the offer and let him have a crack on the dyno. Don't risk your motor TRYING to make it ping on the road.

Yeah Ive been speaking to him, about it. I intend on selling off the current ECU and setup and going with an adaptronic or Haltech plugin. It does seem silly trying to induce knocking especially when its just for logging sake and I know I can't do anything to try fix it.

On a side note, anyone interested in a Z32, PFC, hand controller, greddy profec b sii and the fc edit :P Can't afford the new ecu and tune otherwise.

Remember it can be false knock. The stock sensors arent perfect. So u dont see the knock go up in datalogit?

How high do u see on the h/controller?

Is the dash light flashing?

I agree with GTScotT sarge, take JEZ up on the offer dude.

I challenge you to find another tuner who will put your car on the rollers for free.

I have yet to find anyone that puts the extra free time and effort in like JEZ does :)

He actually cares about how a cars running when it leaves his shop.

JEZ is the man :thumbsup:

be nice if we had someone like jez up this way ! :-(

Where you located? Road trip? :P

Free tuning? Lets go!!

We all wish :yes:

Dash lights flash 3 times and when I see that happen thats when I remember to check the hand controller when I park at home. Usually the number is between 85 - 99. Never had a chance to pickup knock in the datalogit.

99! Pffft.

That's nothing sarge (I AM joking dude)

Mine was hitting the 120+ mark, I have heard it once and it is not a sound I would like to hear often.

Makes you ass clench a few times lol

That is odd.

Have u tried high boost. It will go in a different part of the map, curious if it pings on high boost. Does it do it only after a hot run?

Time for wmi or e85 sarge :)

Just make sure if u run wmi dont run the wmi out... Hey Dave :P

Not necessarily after a hot run. I had the car parkes for about 30 mins after a 15 min drive. Gave it a squirt and the flashing light took away from the fun. E85 or flex fueol is where im heading. Wmi is just another thing that could potentially go wrong. Introducing another independant system would scare me lol. I think the flex fuel is the way to go. I tried that octane 100 with 5 or 10% ethanol content and it gave me a slightly better fuel consumption rate and I recall not a single ping event on that fuel. Get ready jez ill be heading up your way soon.

Smartass! :)

I could always blame the boys who put the fluid float switch in lol

    • My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
    • 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.
