I want to take my 'line to a local mechanic who is known for being great because i get misfiring while idling at the lights. the problem is: the car is under warranty, but the "approved" repairers of my vehicle are companies that i trust as far as i can throw them (not at all). Any work done on the car either unapproved or by an unapproved repairer will void my warranty.

I suspect I need new coilpacks. If i took the car to get "serviced" (can have that done anywhere) and they find out i DO need new coilpacks (or something else relatively trivial), I would be tempted to get them to fix it and just neglect to mention it to the warranty providers. Reason being, someone who knows what they are doing will do the work. IF later on I need to get a real warranty repair done, surely they aren't gonna open her up go "WTF is that... !! non standard coilpacks! no soup for u!" and tell me my warranty is void.. would they? I wouldn't be getting crazy performance fluro purple coilpacks (or whatever the faulty part is), just replacements. For all the warranty company knows, the car could have had them when I bought it, cos of course its second hand.

What do u guys think? I want to have the work done by someone i trust and don't mind paying for parts and repair myself if it means a really dodgy local company doesn't get it's mitts on my car.

And if ur gonna say "well ur stuffed if u really DO need a costly repair!" then yeah... i'll come to that bridge if i need to! so forget about that for now. Reckon a small bit of work like this could cause issues for the warranty? It's such a small thing...

Doubt it.. if they ever questioned you just deny all knowledge.

I'd actually try the warranty place first- maybe you can score a set of coilpacks out of it if they say the ones in the car are faulty.

Checked out the coilpacks, they look fine. Original stock ones, but no signs whatsoever of the arcing.

We actually tested the O2 sensor and found that the car runs exactly the same with it connected and disconnected!! And he got crap readings from it too. He reckons the cars running real rich and may be in what he called "limp home" mode .. or something like that. We're gonna swap it out for a new one and see what happens.

And yeah... I'm gonna fix the 5hit myself than take it to the places i heard were dodgy!

    • 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.
