Did the speedo zero when you powered it up?
No! Still trying to fault find. Any advice?
All good now and working, basically the fix is similar to the tacho recalibration which you need to rev at 6k for 2 seconds so it sees a certain voltage to reset itself.
The speedo needed to be taken to approx 140km/h to also do this.
I suppose you could do it by spoofing the VSS into reading that speed by rotating the pinion gear fast enough with a drill or similar. Or you could do it another way...
I love those boxes of parts, Christmas every time. Speedo looks good, jelly. Glad the needle sorted itself, the next time it gets there you will mean it
Thanks mate and you're spot on with those boxes! I think I enjoy my cars Christmas presents more than my own most of the time
Just to round up the weekend, another delivery of parts came today (Sunday).
New PCV valves with hoses
Chromoly Pivot ball
Nismo genuine pod filter P/N
I'll be 3D modelling a bracket on Solidworks and laser cutting a custom bracket to support the Nismo Pod filter .
Been about 4 weeks since my last update and the parts hoarding continues to trickle through. Covid seems to have held up one item that's been in the post for almost 60days... I hope it eventually comes - if not I have found something else I possibly like more anyway In the mean time, here's a taste of my latest items.
A little ambitious buying 26 year old Nismo S-Tune struts - the rarity and Nismo factor won me over I guess .
The plan is to rebuild them and restore as per new, from research it seems that it can be done by using KYB parts (KYB made them for Nismo).
Also managed to win a pair of brand new Prof Sheepdog blow off valves, they came with all the original documentation. They're to suit a GTR but the flange mount can be removed so I'll either turn up some hose mounts to suit the Z32 on the lathe or design a hose mount to flange mount adaptor
Soon I'll have to find a weekend to start installing some of the items!
Nismo the world!
Time for an update, I guess.
A few more parts arrived, new head unit a Nakamichi NQ722BD. I ordered this from the Russian Federation of all places and it took almost 90 days to arrive... Thanks Covid!
I used to run a Nakamichi CD400 in my previous Skyline and was really impressed with it. The high end Japanese stuff of the day was really hard to beat even by today's standards. I also like the slightly understated appearance Nakamichi brings, however the new stuff still keep smost modern functionality, integrates with google assistant, handsfree calling etc. Also has an option to match interior lights via an app which is a big bonus in my books. Have the trim piece to go above the unit as well but just haven't got it on...
Next I got to doing some maintenance work, A/C re-gassed, new Nismo Pod filter installed, power steering pump rebuilt with a kit from @rob260 @ RGS Performance also fitted new bearings and an AMS performance high pressure power steering hose.
Then last weekend I leapt into the timing belt service with some vapor blasting, powder coating, new drive belt and tidying up of parts along the way. Also added a new clutch fan supplied by @zx299 along with a bunch of other additional trim parts, coil pack & injector connectors, stock charge hose socks now fitted over the black Samco hoses and a heap of other stuff I have already forgotten.
Thanks also to @pauly_adams for overseeing the re-installation of the timing belt
In other news, my Central20 exhaust arrived from UpGarage Japan the other day.
As did my 18" Rays Cerumo C5's from i-parts.jp who Jesse Streeter had sent over....
These will be disassembled, blasted back to raw painted to the original silver metallic centres and re-barreled to match current 9 & 10" width's and offsets of my current Proffessor SP1 copies.
That's about it for the moment... Next year will bring some bigger and more expensive jobs to light
Excellent @MintZ32 , I have been waiting for this!
All looking great, love the exhaust... twin tips suit the car really well. Looking forward to seeing the Rays brought back, cool choice
Thanks Harts, yes hoping the exhaust fits well I chose it because it's a sort of throw back to the stock twin tips. Same with the wheels, they are at least a sort of period correct wheel being manufactured in 1994.
Both should hopefully compliment the #jdmspace the are fitted into quite well
Professional sheep dogs hey, ive got them aswell, thats got my attention of everything so far. Whats this speedo reset you mention? My speedo is out by 10%, and it really bugs me.
G'day mate, how do you find your sheepdogs? Are you running them in re-circ or venting straight to atmosphere?
Reset was just more over that when I received my cluster from a contact from Cyprus the needle was maxed out (something happened to it during shipping). It needed to see square wave voltage frequency equivalent of approximately 140km/h on the Speedo for it to correct itself and start functioning...
I know my taco and speedo out slightly. How do i recalibrate them any advice?
Have you checked/replaced the speed sensor on the gearbox?
No the auto was replaced with a used 96 adm model about 2 years ago (my car is a jdm) also my instrument cluster suits a later spec 95+ and my car is a 1989 model.
According to conzult my taco is 200 rpms out i think and my speedo is reading 7 kmph slower then my actual speed.
Ive never had the speedo calibrated and the speedo and taco are brand new 5 years old units
Do you think a jdm speedo sensor would work better then an adm one?
I doubt there's any difference between the JDM and ADM sensors. Maybe there's a difference between NA and TT sensors though at they have different diff ratios.
On that note are you running larger diameter wheels as the final rolling diameter will have an affect too...
Honestly unsure about what the S1 and S2 cluster differences are aside from plug orientation sorry...
If you have a multimeter at home you might be able to do some testing.
Just found a good video to check if your sensor is working properly.
I too agree i doubt there is any differences between jdm and adm sensors. Thanks for the sensor testing video. Ill check my sensor and see if is reading the correct values.
