could anyone please translate these japanese instructions for me? its for the boost sensor for my MFD display.

i can see there is a vacume pump conected to the sensor and voltage requied at a boost level but not sure if its just a check to make sure its operating as noromal or for calabration which is what im hoping for.

any help muchly apreciated

Looks like its just a check - there aren't any instructions on how to adjust it. Here is the translation for the stuff in the table:

圧力 pressure

電圧値 voltage

大圧気 high pressure

約 approximately

thanks loach i pulled open the sensor and there is 2 dials in it for calibrating it, i need the 2 bar map sensor but i bought this 1.2bar one for $25 so i can play around with it

nissan want $140 for either one and they dont know how long it will take to come from japan with all that going on there atm

Pretty sure the R34 workshop manual has that exact diagram in English - gives you the voltages you should receive with a pressure gauge.

The 1.2bar sensor is the regular map sensor used on R34 GT-T/GT-R - the 2.0bar comes as part of the kit for the updated nismo MFD boards (though obviously you can source it separately).

No worries. Usually if a pressure sensor has two adjustments then one adjustment is to set the zero and the other the range. I usually set the zero first and then the range then recheck the zero. The two adjustments affect each other so sometimes it takes quite a while to get it. If you have to keep adjusting them set the zero then the range then when you recheck the zero go half way to zero.

For example: if when you recheck the zero it says 5 then set the the zero to 2.5 and recheck the range. Then recheck the the zero and if it says 3 set zero to 1.5 and recheck range again. Keep doing it and evetually you will get there. Good luck with it.

Can I contribue to this? I got 'atmospheric pressure' where LOACH got 'high pressure' im sure it was translation typo.. and sounds like the special tool they have/use does a vacum pressure test on this Boost Sensor. thats why the table line two shows a -47kpa instesd of a +47kpa.

sorry if this is what someone has already said.

cheers!

edit on grammar!

This one - 大圧気 high pressure ??

Its definitely possible it is wrong but I am pretty sure this kanji 大 means large/big/great etc so I assumed it is the full boost setting for the R34GTR (80kpa I think). Also I would imagine that you would want a high pressure check and a low (less than an atmospheric) reading to check the working range of the pressure sensor. I could be wrong though - maybe its only to check the vacuum range. Anyone else got any ideas?

I was absolutely wrong and you were absolutely right. Sorry about that and thanks for the information most appreciated.

Guess nobody wanted to listen to my suggestion; Here I've done it for you:

Maybe no one who read the thread has an R34 workshop manual. I certainly dont. Thanks for the picture anyway.

NIS.26L - Sorry about the incorrect translation, Hope it all goes well for you.

    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
    • My experience with Rising Sun Exports Before agreeing to the sale I tried to do as much research as I could (obviously), his Facebook reviews are 98% and he goes Live at least once or twice a week. I contacted 2 people in the UK who had used him for their imports, both had positive feedback. His explanation and talk through of the import process was thorough, answering any query no matter how stupid it was. It felt as soon as the money was sent, communication dropped off. I asked for shipping updates every 2 weeks or so, not wanting to pester him, he never had any updates. I wasn't informed the car had been dropped off at the port, I only found out by his Facebook story. I asked for the photos taken at the port, knowing he would need some for insurance purposes. I received a few 5 second clips and that's it. When asked again, he said his staff had them. Weeks later I asked again, he tells me he doesn't have any, but does have 50 photos from the original advert. I never received them. I eventually got the documents sent via WhatsApp after I mentioned the port was requesting them. I purchased a CarVX report, to find out the vehicle is a Grade R with recorded accident damage, first recorded in 2017 when it was first auctioned. He never told me the grade, then again I didn't ask. His response was "Grade R means nothing, it wasn't chassis damage". Still, I would have liked to have been informed about it. Jon prides himself on being open and honest when it comes to inspecting cars, it's his main job doing so at the auctions for customers. When the vehicle arrived in the UK I noticed a few little cosmetic issues. It's a 21 year old car so it wasn't going to be mint condition. The side skirts are cracked on each corner and the sealant is failing. The front grill on the bonnet/hood isn't secured very well, mounting studs are missing. Both minor things, but again, it would have been nice to be told. During a Facebook Live walk around video of the vehicle, he mentioned it has a front Whiteline anti roll bar/sway bar. While on the inspection ramp, I noticed the stock item has been installed. When first questioned, his response was "the ARB? Switched? Since when, it never had them". Since sending video and photo evidence I've not received a response. I'm probably being over critical of the overall condition of an old car, but all I wanted was honesty (which he claims to have). I'm aware I wasn't his only customer, he's busy doing XYZ but other reviews praise him for great communication with regular updates and photos, I felt I didn't receive the same treatment.
