hi guys having dramas again

today i attempted to hook up my greddy emanage blue it is brand new and i got the adapter loom for the ecu so i didnt have to splice into wires and what not just wanted plug and play, anyway after plunging all in and reconnecting battery tryd to turn over and it wouldnt fire, then i noticed a electrical burning smell so i quickly disconnected battery and went looking for the problem couldn't find it anywhere so disconnected the emanage and plugged the ecu back in now it wont fire with that ether, so did a error check and im getting error code21 (ignition signal) and error 34 (knock sensor). Checked the coils and they are getting 12v, gnd and signal with 0.4v with ignition on and fluctuates when turn key?????

does anyone know what the hell i have done and how to fix

all help will be much appreciated im happy to pay someone if theres anyone who can help or knows someone who can help me fix it im on the north side of brisbane cheers guys

It's a saying. Any time you can smell electrical burning.....it's probably too late.

I got it, my old TAFE teacher always used that saying... and he used to quote this alot "best thing since sliced bread and condoms!"

OP - take to any auto electrician as it will be cheaper in the long run then diagnosing over the internet..

just to wrap up the thread turns out im the only person lucky enough to all 6 coil packs die at one which caused the code 21 that coupled with the afm carking it was why it wouldnt start and the code 34 just disappeared so we are putting that down to its female and was just being temperamental cheers anyway

      Blue slip

      I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
