Ok.. Here is my story so far

Get the car , runs perfect except for the 4,500- 5,500 misfire under load..

I put in a new set of plugs over the weekend, champion double platuim plugs with a 1.1 gap

Also did a oil and oil filter change on the car, Genuine filter and Repsol 5W/50 full synthetic oil.

Take the car home from doing all the work , hit the freeway and the car struggles when it gets up to around 80km/h + like it feels like someone has thrown out the ancor and im pulling it along.

Just wondering if anyone else has had this problem. Car is totally stock aswell!

Cheers

Mick

ok, i have experienced the same sort of probs before.

could be a number of things, have you installed a boost controller and been playing around with it without a proper dyno tune (as what i did)

if no then could be fuel pump shat itself, AFM, injectors, turbo leak etc. best to get it up on a dyno somewhere and find out whats happening.

Nope no boost controller or anything

Wouldnt think that it would be a fuel pump or AFM, all we did was change the plugs and oil in it..

Dont know what oil was in there before, but it must have been done by the dealer i brought it at cause it had a ryco filter on it!

      Quieter performance exhausts (or muffler add-on options)

      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
