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?

      Quieter performance exhausts (or muffler add-on options)

      By Murray_Calavera · Posted

      Nope.    Grab a varex and turn it down as you get close to home, win win?

      Quieter performance exhausts (or muffler add-on options)

      By f00stx · Posted

      So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?

      The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.

      Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.

      Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks
