Folks,

I was driving along tonight and all of a sudden i noticed my Tacho bouncing up and down, then my VCS and Slip lights came on, then my speedo stopped working and when i put my indicator on it would cut in an out - ie not tick properly. Then the car gave a big thud from the tranny as it shifted gear - so i think its highly likely the Auto ECU wasnt changing the tranny properly as it couldnt get a correct RPM reading. I put my foot down and it didnt down shift. When i pulled up to lights it abruptly changed into 1st. I turned the car off and back on again and all was normal. Later on in the evening the dash started doing the same thing, and the tranny started not shifting properly (with the dash going funky etc). I then put the Auto into the Manual mode but the dash Drive Gear symbol didnt update, and the number of the gear didnt display. I could push - or + and nothing would happen, I then put the car in Reverse and the display still read D, but the car reversed OK - I then moved it back down to D and the Auto Check light quickly blinked on and off. All the time VCS OFF and SLIP were illuminated.

It has been raining here but other than that I cannot think of any other reason for this to happen.

Could it be the Dash itself on the blink? I assume like some Nissans the speedo and RPM go via the dash before going to the ECUs? If thats the case it would explain the tranny going haywire, but I dunno about the VCS off and SLIP. I tried pressing VCS but the light stayed on.

Any insight would be great!

ive noticed in the wet in the last few days when the vdc is on and the wheels spin a bit and the slip light comes on and it stops spining but the slip light then stays on and the vdc off light stays on aswell even when you try to turn it on. when you then turnoff the car they turn off and its ok, until the vdc kicks in again.

I belive mine are just error codes that a scanner will pick up and fix, due to all the electrical work carried out on it recently.

They that thud you are talking about i never had but i would get that checked out imidiatly.

read the owners manual.The infiniti one says any probs with the vdc or gearbox and it will go into 'safe mode'

untill it is restarted,to protect the transmission.

i agree that u should get it checked asap-and get the oil changed as well.

hopefully they have the correct diagnostic program to check the electrics etc at your local nissan dealer???

Ive found what could have possibly been the issue, I have no battery cover so there was half an ocean sitting around the main wiring loom where it runs under the battery. The past few days have been fine so no rain, and the tranny is performing normally. I am going to have to price up a battery cover me thinks!

The thud was probably from the jerkyness of the gearshifting. But having the whole dash go haywire says something was going funky everywhere!

i have seen a similar issue with my auntie's hyundai sonata. out of nowhere the dash started to go aywire, dropping gauges down to zero then flipping up to max etc.

turned out to be the negative terminal of the battery wasn't making good contact..

the water might have been screwing up the battery somehow.. get a cover over the battery! what happened to the stock cover?

Raining again tonight and after an hours drive in the rain my girlfriend steps out of the car with one wet shoe. Interesting... i had a bit of a look up the footwell and low and behold I see water dripping down the wiring looms! I dare not look behind the ECU cover just incase im in for a shock. Sh!t.

Is there anywhere for the water to come into the cabin?. I mean der, of course there must be somewhere but im not sure where. Possibly thru that air vent behind the battery (i think thats what it looks like). Would it come through there if I had no battery cover? Better yet, i wonder how water is getting down there...

Thanks!

Did you get a warranty from C-Red when you bought it? Might pay to go back and ask them for the battery cover and to see if while they were doing all the mods wether or not they might have taken a cover off around the ecu unit etc and forgot to put it back, might be a simple thing and save you alot of stuffing around.

P.S. I hear the guy in the meat van loved your sound as well :) .

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      I checked the injectors again (1 and 2, since they’re easiest to access) to make sure they weren’t clogged. Even though the entire fuel system had been cleaned, I wanted to be certain. Everything looked clean, so I reinstalled and connected everything. When I started the car to confirm everything was okay, it immediately revved up high, so I shut it off straight away. I checked to see if I’d missed a vacuum hose or something, but everything was connected. On the second attempt, the car ran without the high idle, but I noticed a distinct “compressed air” sound coming from the engine bay. Tracing the sound, I pushed injector #6 forward slightly and the noise stopped — it turned out it wasn’t seated properly, despite the fuel rail being bolted down. While holding it in place, the car idled steadily without stalling and ran for over 5 minutes. At this point, I pulled all six injectors out just in case I hadn’t seated them correctly or dirt had gotten onto the O-rings. Unfortunately, I discovered that I had damaged 3 out of 6 injectors (the OEM 270cc ones) during installation. So yes, this was my fault. Since only the pintle caps were damaged, I’ve ordered a Fuel Injector Service Kit from NZEFI to refurbish them. In the meantime, I reinstalled my new injectors – the car now idles fine for over 15 minutes without stalling. I have not attempted to drive it so far. It’s not perfect yet, as it hesitates when the throttle is pressed, but it’s a big improvement. Unplugging the IACV with the new injectors idles at around 800rpm, even with the IACV screw tightened fully. But this is probably due to tune.

      I wanted to try and preserve the front bumper as long as possible, they're not cheap and are made to order in Japan. Taking inspiration from my previous K11 Micra build where I made an undertray for the Impul bumper, I did the same for this BN Sports bumper but a little slimmed down.  This time round I only made a 'skid plate' (if that's the correct wording/term) for just the bumper surface area, the Micra version covered the gap like an undertray. Starting off with a sheet of mild steel approx. 0.9mm thick 4ft x 2ft in size. I traced around the bumper, cut it out and cleaned the edges. Luckily I was able to get two halves from one piece of metal In the video I installed it as is, but I've since then I've removed it to spray and add a rubber edging trim. The rubber trim is suitable for 1-2mm and it's a really nice tight fit. The bolts had to be loosened due to the plates being too tight against the bumper, the trim wouldn't push on I used some stainless M6 flat headed bolts for a flusher finish (rather than hex heads poking down), I believe this style fastener is used for furniture too incase you struggle to source some. The corner's are a little wider, but this may be an advantage incase I get close to bumping it  The front grill got some attention, finally getting round to repairing it. Upon removal one fixing pulled itself out of the plastic frame, one side is M8 that fixes inside of the frame, where as the other side is M5. Not knowing I could get replacements, I cut down an M8 bolt, threaded it inside the frame along with a decent amount of JB Weld.  The mesh was replaced to match the bumper. One hole on the bonnet/hood had to be drilled out to 8mm to accommodate the new stud, once the glue had set it could be refitted. I think the reason the grill was double meshed was to hide the horn/bonnet latch (which makes sense) but I much prefer it matching the bumper Bumper refitted and it's looking much better IMO The Youtube video can be seen here: https://www.youtube.com/watch?v=bVZP35io9MA
