Not exactly but it appears the IPDM has sat for some period of time horizontally with water in it, im thinking maybe when the car was resprayed (it was already a non standard colour when i bought it) it may have sat for a period of time without the bonnet on it, the bonnet bolts were loose when i got the car, along with some other earths the engine mounts and a few other bolts... Ive since gone over just about every bolt i can find for piece of mind.

I checked the car over as well as i could before i bought it, ive had most of it apart since and i cant see any signs of a major accident, im told it was that colour when it came into the country so maybe just some dodgy jap panel beaters that did the respray?

Hmmm, a little less confident today, i went to the workshop last night and asked my mate who had been there all day if the car had sounded the horn or done anything wierd... As he said "no, not at all" it started beeping... i walked over and turned it off and then on again...

Perhaps its lonely having sat in the corner for at least 6 weeks and was just happy to see me?? coils have been shipped and should be here by the end of the week... only time will tell i suppose...

awww it misses you :)

if it has the dealer fit alarm on it and you leave the window down and make noise near it the thing does go off. been there already.

Well, coil packs arrived today, the boots on them were very dodgy so i put all the original ones onto the new coils. Started the car and it was evident it was missing on more then a few cylinders.. wouldnt even rev to start with, checked all the coil packs and all were sparking.. seems the injectors were stuck and all came good when it got up to temperature except No. 4... tried tapping the injector while it was running but to no avail...

Wasnt prepared to pull the manifold off tonight will have another look tomorrow, only error code showing up was a miss fire.. funnily enough.. going to do a compression test tomorrow before i pull the manifold off just to rule out the possibility of a broken ring, but i highly doubt that will be that case... At least it runs and my software talks to the car, just frustrated atm was looking foward to driving the bloody thing... Im thinking its just a stuck or blocked injector, well hoping...

Pulled the injectors out today and took them to a local injector cleaning place. The suspect one was blocked and apparently none of the others were flowing poperly which is a good sign that, that is the only thing left wrong with it atm... will know tomorrow i suppose...

Good Luck dude, pretty sure the whole forum has it's fingers crossed for you.

On the bright side - is there really that many more parts/issues it can be? :rofl:

The more time it takes the closer you are to a solution.

Cheers guys.

Well my patience is really being tested now...

Injectors all clean and nice and still missing on No. 4, it has spark and it has fuel it can only be a timing issue now.. I connected my turbo xs ECU and still the same problem which leads me to believe its sensor issue now.

Now these things use 3 sensors a crank angle sensor activated by a plate attached to the ring gear the sensor is mounted in the bellhousing, I have ordered one of these but it most likely wont be here till after christmas, and 2 camshaft phase position sensors, these the worshop manual tells me tells the computer exactly where each piston is in its cycle... I ordered both of these today and they will be here at lunch.

If this doesnt work i may set fire to the thing..

Cheers guys.

John,

How bad is your miss?

I have a tiny little miss when the car is idling but nothing noticeable at all when driving. I'm thinking mine might be more to do with the aftermarket exhaust.

If this was my idle pattern and 1 dot = 1 second, the gaps would be the miss i have

......... ......... ......... ......... ......... ......... ......... ......... .........

I'm not sure if you would even call it a miss.

Yeah its not as bad as it has been.. infact it pretty much sounds like what your describing.. and considering i havent heard and or driven it for that long, its definately not as pronounced as it was before i got the injectors cleaned but its still throwing the check engine light with a missfore error aswell as an unknown error. im going to take it for a drive tonight. i snuck away at lunch time and changed the sensors with the new ones and its still there. Just picked up a cheapo jaycar oscilloscope so i can now test all the sensors and triggers.. so if driving it doesnt fix at least ill be able to pin point the problem.

Edited by NA_R33

Well i left work early, took it for a drive, Complete miss on No.4 yet its sparking and has fuel... Unless for some odd reason the when the plug is in the head the power from the coil is not conducting through the plug?? i got nothing left, put the oscilloscope on all the sensors and there all reading correctly, there is good compression on that cylinder it has fuel and its wont f**ken run!!! im loosing my mind over this...

Well after looking at it a bit more the oscilliscope showed the no. 4 injector trigger to be running at less than 2 volts...

So i only have 2 options now.. some how try and source a standard computer, god knows how much that will cost or go a full stand alone ecu like the autronic... mmmm

Dude, give this a try. Maybe get in contact with the seller.

Not sure if it would be the same tune as the V35 but for $150USD it may be worth a shot.

The autronic should be here tomorrow.. Going to wire it up so the standard computer still thinks its running the car to keep the BCM happy... Been so busy with work the last few weeks, the riggers managed to damage all 3 CNC's and the manual lathe, idiots ah well. Yeah will probably wire it up next week... Should be good :domokun:

Thanks again for all the help guys.

    • OK, so regardless of whether you did Step 1 - Spill Step 2 - Trans pan removal Step 3 - TCM removal we are on to the clean and refill. First, have a good look at the oil pan. While you might see dirty oil and some carbony build up (I did), what you don't want to see is any metal particles on the magnets, or sparkles in the oil (thankfully not). Give it all a good clean, particularly the magnets, and put the new gasket on if you have one (or, just cross your fingers)
    • One other thing to mention from my car before we reassemble and refill. Per that earlier diagram,   There should be 2x B length (40mm) and 6x C length (54mm). So I had incorrectly removed one extra bolt, which I assume was 40mm, but even so I have 4x B and 5x C.  Either, the factory made an assembly error (very unlikely), or someone had been in there before me. I vote for the latter because the TCM part number doesn't match my build date, I suspect the TCM was changed under warranty. This indeed led to much unbolting, rebolting, checking, measuring and swearing under the car.... In the end I left out 1x B bolt and put in a 54mm M6 bolt I already had to make sure it was all correct
    • A couple of notes about the TCM. Firstly, it is integrated into the valve body. If you need to replace the TCM for any reason you are following the procedure above The seppos say these fail all the time. I haven't seen or heard of one on here or locally, but that doesn't mean it can't happen. Finally, Ecutek are now offering tuning for the 7 speed TCM. It is basically like ECU tuning in that you have to buy a license for the computer, and then known parameters can be reset. This is all very new and at the moment they are focussing on more aggressive gear holding in sports or sports+ mode, 2 gear launches for drag racing etc. It doesn't seem to affect shift speed like you can on some transmissions. Importantly for me, by having controllable shift points you can now raise the shift point as well as the ECU rev limit, together allowing it to rev a little higher when that is useful. In manual mode, my car shifts up automatically regardless of what I do which is good (because I don't have to worry about it) but bad (because I can't choose to rev a little higher when convenient).  TCMs can only be tuned from late 2016 onwards, and mine is apparently not one of those although the car build date was August 2016 (presumably a batch of ADM cars were done together, so this will probably be the situation for most ADM cars). No idea about JDM cars, and I'm looking into importing a later model valve body I can swap in. This is the top of my TCM A couple of numbers but no part number. Amayama can't find my specific car but it does say the following for Asia-RHD (interestingly, all out of stock....): So it looks like programable TCM are probably post September 2018 for "Asia RHD". When I read my part number out from Ecutek it was 31705-75X6D which did not match Amayama for my build date (Aug-2016)
    • OK, Step 3, if you need to remove the valve body, either to replace it, the TCM, or to do a more complete drain.  First, you need to disconnect the TCM input wires, they are about half way up the transmission on the drivers side. One plug and the wires are out of the way, but there is also a spring clip that stops the socket from sliding back into the transmission. On my car the spring clip was easy to get, but the socket was really stuck in the o-ring of the transmission housing and took some.....persuasion. You can see both the plug to remove (first) and the spring clip (second) in this pic Incidentally, right next to the plug, you can see where the casting has allowance for a dispstick/filler which Nissan decided not to provide. there is a cap held on with a 6mm head bolt that you can remove to overfill it (AMS recommend a 1.5l overfill). Final step before the big mess, remove the speed sensor that is clipped to the valve body at the rear of the box.  Then removal of the Valve Body. For this the USDM Q50 workshop manual has a critical diagram: There are a billion bolts visible. Almost all of them do not need to be removed, just the 14 shown on the diagram. Even so, I both removed one extra, and didn't check which length bolt came from which location (more on that later....). Again it is worth undoing the 4 corners first, but leaving them a couple of turns in to hold the unit up....gravity is not your friend here and trans oil will be going everywhere. Once the corners are loose but still in remove all the other 10 bolts, then hold the valve body up with 1 hand while removing the final 4. Then, everything just comes free easily, or like in my case you start swearing because that plug is stuck in the casing. Done, the valve body and TCM are out
    • OK, so if you are either going for the bigger fluid change or are changing the valve body which includes the Transmission Control Module (TCM), first you should have both a new gasket 31397-1XJ0A and a torque wrench that can work down to 8Nm (very low, probably a 1/4 drive one). You can probably get by without either, but I really didn't want to pull it all apart together due to a leak. First, you now need that big oil pan. The transmission pan is 450 long x 350 wide, and it will probably leak on all sides, so get ready for a mess. There are 24x 6mm headed bolts holding the pan on. I undid the 2 rear corners, then screwed those bolts back in a couple of turns to let the pan go low at that end, then removed all the middle bolts on each side. Then, undo the front corner bolts slowly while holding the pan up, and 80% of the fluid will head out the rear. From there, remove the remaining bolts and the pan is off. You can see it is still dripping oil absolutely everywhere...it dripped all night.... I got another couple of litres when I removed the pan, and then another few when I removed the valve body - all up another 4l on top of the 3 already dropped in step 1.
