V36 Rev Probs, Firmware Update Anyone?

[awsam]

Just curious if anyone has had the v36 update applied, and where/how this was done?

I'm not able to have the source of my pv36's problems found.

The car hesitates when taking off from a stopped start, usually at traffic lights. It just skips a beat.

Then while driving it continues to skip, feels like it's being pulled or cutting out very quickly every 2-5 seconds. (rev's drop 150-300rpm)

I've read there is a update that eliminates this issue, does anyone experience this or has anyone

found somewhere to get the update?

I have also read that a faulty camshaft position sensor, has anyone else experienced this?

I have not tried a reset yet (dc battery, pump brake peddle 10x) from what I've read this is not the answer, but might try anyway.

Do I pump the pedal fast/med/slowly?

Greatful for any information anyone has, the problem is getting quite bad.

2008 pv36 sedan btw.

I can often accelerate through the skipping, quickly hitting 80 for 200mtrs will fix the problem until I next turn the car off & on again

"Pedal", not "peddle".

i am having the stutter problem when stationary, an uprev tune would normally fix the problem, can cost up to 1k so i have decided to live with it

I'm not one to usually spend more than 10k on a car, and just can't accept it running this way. There must be something that can be done

You need to get in on a Consult 3/3+ and check the crank and cam sensor waveforms, only a Nissan dealer would be able to diagnose this kind of fault properly imo, without swapping sensors aimlessly... But the cost...

Or you can just change the cam/crank sensors.

If only you were local, is yours a 3.5L?

[awsam]

Yeh it is the 3.5 sedan.

Have trouble getting nissan dealers in Adelaide to pay any attention to an import.

[colin.ssc]

My mechanic works at a Nissan stealarship but he has said that they are not able to get firmware for imports because they have Aussie version Consult 3 which does not allow them to download/access firmware upgrades for cars that they do not sell here.

[awsam]

^ fair point, makes sense. Real shame though.

What about getting Cam shaft, Crank shaft, o2 sensors?

[scotty nm35]

^^ this is a load of crap.

Nissan have access to the correct software and choose not to diagnose, because they know it will be a headache. If they refuse to help, try another dealer.

I have the aftermarket consult 3 unit here, but unfortunately it doesn't run the waveform diagnostic oscilloscope part of it.

This might be your only shot at fixing it cheaply, The sensors are available in the US at around $200 us the set, although I am hoping the aftermarket ones I am ordering in work just as well at a fraction of that price.

Edit: It's not just a bad batch of fuel is it? Have you put a fresh batch of 98 into it?

[awsam]

Nah, this has been an issue for 5 weeks now, progressively getting worse. I only use BP98. The problem is quite embarasing, annoying, and can't be good for the engine.
There's only a couple of dealers in Adelaide, have only been to Unley Nissan so far and they were useless. Infiniti tell me via my email enquiry there is a store/workshop opening

here "In the near future" but no further details.

Can't remember the brand name, but i've read a aftermarket Cam shaft sensor had a slightly wider plastic clip and can destroy the clip engine side if brittle.

I found this brand for $50 per sensor, not inc postage. But can't for the life of me remember details as I dismissed it quickly after reading the issue.

Are you replacing just the Cam shaft sensor? I take it you're experiencing similar?

[scotty nm35]

I have replaced a few sensors on customer's cars, there is usually another reason for the failure/issue though. The alignment could be off a few MM.

They can diagnose...they did on mine. They just cant get the firmware downloaded.

[scotty nm35]

Ahh, right.

Apparently I can copy and paste firmware.

There is of course no need for a firmware update, the car was working fine for years, then started running rough. There is a fault somewhere that needs to be fixed.

[colin.ssc]

They could download the firmware from my ECU to their computers. Then they tried flashing my ECU with 370z, Murano, 350z and all...and then installed my original one back.

[awsam]

Nissan called me today to tell me Nissan jap simply refuse to send them updated firmware. Also said in Adelaide only place to buy OEM parts (orderd from Jap) is from Main north Nissan. Failing that the guy on the phone assured me I could order from a GTR dealer in Melb.

Scotty, when do you think you'd be getting around the putting the sensors in? Pretty eager to hear your results so I can follow

[scotty nm35]

I will let you know when they eventually turn up.
