Hey guys

My car has been misfiring for the past 2 months and after going to 3 different mechanics and even after changing a number of parts its still no good. However the last mechanic thinks it is most likely either the O2 sensor, Crank Angle Sensor or Computer (eManage) thats causing the problem because the car missfires after 2000 revs only and especially when the engine is hot - it sometimes won't even allow it to power on when its hot so once cool, it will power up but still missfires. Anyways, i'm getting the shits now and I really want this fixed. I'm getting it taken to this place DynoTune in moorebank and was just wondering if these guys will be able to sort it out.

Thanks guys

these guys are shit talkers.

they want to charge me $400 and they have not even found the problem yet. The bloke on the phone said they will do a computer test which will take an hour and a half at $80p/h and now its $400. Their solution is to buy their EMS computer and get them to tune it all up $2500 plus the $400. And I bet then, the problem will still be there as the problem is not with the computer to begin with. I knew I was gona run into this shit by going to a "accessible, nearby place". Unbelievable.

Whether you consider this a whinge or advice, DO NOT TAKE YOUR CAR TO DYNOTUNE & EFI

They are a RIPOFF and have "diagnosed" the 34 with same results as I suspected over 2 months ago, only they charged $400 (without advising me of these costs). Will be taking this to fair trading.

that's such a typical story. so many rip off tuners around.

i recommend C&V Performance at caringbah.

i've used them. they know their shit. and they really look after their customers cars.

also, they dont charge like a wounded bull. and if they quote you a price, and run overtime, they stick to the agreed price.

obviously this is my personal experience. i'm very happy with them.

HA HA,the c**ts have no clue! I went to them years back and they tried to rought me aswell (jason the owner) told him to snap out of it before i snap his jaw,f*kn rip off dogs :)

damn darko.your car still has the same probs.

yeah you should get greg at autosport to have a look at it.he knows skylines inside out.

also TO4GTR had the same problem.it turned out to be a fouling injector.

does the emanage have a hand controller so that you can check duty cycle/overall performance of the injectors? this could bring to light a problem in that area,if there is one.as per dave's injector problem you learn from it.

here are a few possible areas that it could be.

*coil packs.

*coil pack igniter.(if any of the wires leading from the "coil pack igniter" are not giving a reading/or any that are reading spastic on the multimeter.you have a problem.)vise versa for the wires that lead to it from the computer.

*Crank Angle Sensor.(if the computer gets the signal to fire the coil packs at the wrong time you definantly will have a missfire.)

*exposed wires in the ignition system.(that means a thourough check of all the wiring in the ignition system.)

*spark plugs.

*water in the airbox.

*leak in the intercooler to manifold pipework.(the car will spit out black smoke,right after it splutters,if this is the case.)

*afm is a possibility.though dont quote me on that.its only a suggestion.

*the computer.

i've got an idea.

connect the emanage to a laptop and log the data when it is misfiring.

click on the data logger option, which is the one ive circles in RED.

make sure you choose all maps by clicking the button ive circles in ORANGE and choosing the same ones i have chosen then click OK.

to start logging click on start (derr) which is in GREEN.

choose to save the logged data then put it into a .zip file then PM it to me.

ill have a look at it and see if i can help you with anything.

hey guys I appreciate the help but I just got off the phone to Brett (midnight performance) and he has 110% identified the problem which is the fuel pump and fuel pump wiring - why am I not surprised the guy knows his stuff... he has a 32 GTR and R33 GTST S2 himself. I got referred to him by Minh (DR GTR) and once I got to his workshop I realised I know him and hes a top bloke, he helped me out before too back in the r32 days so I was 100% confident that the car will be fixed in no time.

Anyways, I will now tear Dynotune a new ahole =)

and rememmber: DO NOT GO TO DYNOTUNE & EFI Moorebank

hey could you please give the contact detils for midnight performance?

    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!
    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
    • 310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.
    • The filter only filters down to a specific size. Add to that, the filter is AFTER the pump. So it means everything starts breaking your pump even if its being filtered out.
