With rev limit 8000rpm... does it use the column N19 or only N18?

Also see my base map please... this is with recalc base...

N19-P20

N20-P20

It isn't logical to be so low right? It must be more than N18-P20 right?

Why I ask all theese..

My car run 2bar-30psi and I don't have datalogit right now to tune anything in my car...

As I run this boost I only intersting for row p20 and cells from n13 to n20.

I run the car with rev limit 7500... it was ok 10.8afr! I run it 8000rpm... again ok 10.8!

But ofcourse at theese rpms with so fast car it is different to see the gauge and understand. Also the last rpms before the limit you cannot understand if the numbers are from rev limit or the afr from last rpms.

So I want to tell me if the map seems to be ok to theese cells or in theory the car will be very lean if it will read the N19-P20,N20-P20!

Remember in the foto is recalc the base.

My guess that theese cells must be 40 and 42 is right?

Also the car take out oils at theese boost.. I undestand it because I don't have oil catch can and the oils goes at the turbo and many smokes suddenly filling all the car haha!

The first time my heart stop for some seconds to work!!!

i really need to see both fuel maps: feel free to email me the map [email protected] i will have a look over it and do a few adjustments if neccessary. Generally speaking if the map ponts in the main map are linear accross the rpm points then yes the N19 and N20 points you have highlighted should also be linear (increasing) not decreasing.

URAS so you mean that N19 and N20 must be sure more than N18 right? So more than 39... and now is only 25!!

With 8000rpm limit will be lean the last rpms??

In the foto I have recalc the base!!

You have two emails :)

just emailed the maps back, i had to make some big changes so you will need to reload them via datalogit and check AFR's the original fuel and base maps were full of big holes.

      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
