I don't think there is any calibration as such? The sensor senses how far open it is and feeds the signal to the ECU as far as I know.

Adjusting your cable is another story. Take out the slack, and you could use a consult cable and software to confirm WOT. (with the car ignition on, but not running)

what i mean about calibration is so the tps is sending the right signals to the ecu cause at the moment i think the tps is out of its right position, meaning that is prob sending a signal that the throttle is like 5% open when its actually closed.

i just want to know how to set the tps back to the right position so its like 0% thorttle and the ecu is actually reading 0% thorttle

get me?

there has to be another way, like using a voltimeter using the resistants on it etc etc

It can be done that way, you will need to find out the correct voltage for it (EG: the 300zx tps is set to 0.45v at 0%) the easiest way to do it is to find the correct voltage for closed throttle and then get a multi metre in there and set it to it. If you have someone with either a consult cable or an ecutalk lcd display this can be done easily (5 mins)

yeah you can just use a multimeter to check the voltage. the voltage should be around 0.45v when closed. this is pretty standard for a lot of nissans. pretty sure the sr20 is also the same. there will always be a slight variance though. i'm not sure exactly what the allowable margin is, but if yours is dramatically different then i'd have a play around with it. if i get time i'll have a look through some stuff i have and see if it says.

Sorry for dig up this topic, hopefully i'm in the right place to post my problem. Currently my car(bnr34) MFD show the throttle reading at 1-2% when idle, for what I know it should be 0% when idle, I pop-up my bonnet and check the stop-screw, it is backed off without touching the throttle linkage(1mm gap), but why the reading show 1-2% when idle? Will TPS cause the MFD throttle reading like this?

your MFD is probably guessing what '0%' means. e.g. if it has decided 0.44v is 0%, then if its reading 0.46v then it will show as 1-2%. maybe there is a setting in the MFD to calibrate the 0/100% throttle voltages?

      R34 Skyline climate control unit transistor

      You can’t see much on the other side as the lcd is there I don’t think it’s the same as the m33 beside it as the markings on top is not the same was hoping someone had a good quality photo or if they just happened to have the unit in hand, quickly take the cover off and take a photo to clearly show the marking on top to identify the diode   the unit is currently with an electronics repair shop so I can’t take another photo at the moment hopefully they are smart enough to know if it’s a zener diode or not

      WGNC34 - floor mats

      By soviet_merlin · Posted

      I'd be very surprised if you can buy new OEM mats. But if you can, I want some too!  Do you have links to the variations you found? Also, where are you located? I found that Nengun is happy to list items to purchase but when you do buy them you'll get an email that it's actually discontinued. As far as I know the variations in floor mats are different colour schemes as well as automatic and manual having a slightly different shape. The automatic ones fit into a manual car without issues, but I think you'd have trouble fitting the other way around. I have photos that show the shape difference if you care. FWIW I bought sets of used floor mats in decent condition at yahoo auctions.

      WGNC34 - floor mats

      By Marek · Posted

      Hi 🙋‍♂️. Just bought my Unicorn but the interior need some minor work so it would match my expectations ;). I noticed it is hard to get used oem floor mats in good condition so i started to dig if there's any chance to buy set of new ones. I found two websites - nengun and amayama and it looks like one can still buy factory new floor mats in Japan, but thers a small issue. Some mats (i assume genuine, oem ones) are marked as G4900 and these are "discontinued". The ones you can buy are marked as G4911 but i have no idea if these are also oem, made by other producer or some lower quality replacements that looks entirely different. Can anyone help? 😃  P.s. there is also some strange indication - 0V005, 0V015 and 0V505. Any idea what does it mean? Would appreciate any help with this 🙏

      Hi, Marek here 🙋‍♂️. I finally fulfilled my longtime dream - recently bought Stagea and now waiting for it to arrive in Poland. There's only few of these in my country, and one of the owners  recommended mi this forum as a source of all the info i'd need since now i own one  so here i am.

      Version 1 aluminium airbox is.......not acceptable No pics as I "didn't like the look.....alot" Even after all my "CAD", and measurements, the leg near the fusebox just didn't sit right as it ended up about 10mm long and made the angle of the dangle look wrong, the height was a little short as well, meh, I wasn't that confident that Version 1 was going to be an instant winner I might give Version 2 another go, there's plenty of aluminium at work, but, after having in on and off a few times, and laying in the old OEM airbox without the new pod filter and MAF, there may be an option to modify the OEM air box and still use the Autoexe front cover and filter.... maybe This >  Needs to fit in here, but using the panel, and not the pod, the MAF will need to fit in the airbox though> I'm thinking as the old OEM box and Autoexe cover that is sitting in the shed is just sitting around doing nothing, and they are relatively abundant and cheap to replace if I mess it up and need another, it may well fit with some modifications to how the Autoexe brackets mounts to the rad support, and some dremiling to move it get in there, should give me some more room for activities, as I don't want to move the MAF and affect the tune Sealing the hole it requires to stick it in the air box is simple, a tight fit and some pinch weld will seal it up tight  I am calling this a later problem though
