limiter is set @ 7900 but peak power is reached at around 6700 /6850 rpm and as Alistair says i dont wanna blow the poor old turbo's up just yet even though they are next on the hit list gt-rs's i think.

Alistair if i win the lotto tomorrow night i will invest a bit in the dyno for ya just so long as i get to use it when needed lol

Been ages since I posted on SAU. A couple of things need clarification:

1. The limiter on Gary's car was set to 7900. The scaling on the graph is wrong. It is calculated by the dyno as a function of roller rpm, not measured. I should have printed the graph in road speed to save the confusion.

2. The boost is not dying off. I did that on purpose. It has been tapered to provide maximum midrange punch without top end over-speed. Even if the turbo's could sustain that boost level at high rpm, the power gain would be minimal, if not non-existant.

3. Pricing for Vi-pec refer to Alistair. Rec retail on the R32/33/34 board is $1,666.50 inc GST supply only. Installation and configuration is suggested to be around $350 and dyno tuning over and above. The ecu's come with start-up maps only.

what lumpy said :laugh:

i am extremely happy with the oomph once the boost hits

only down side is the mrs now thinks the car has enough power :P

she don't want me to go bigger turbo's

In case anyone is interested there's a great thread in forced induction on a new Australian plug in ECU for rb20/25/26

http://www.skylinesaustralia.com/forums/Pl...ng-t218179.html

Briefly :

Direct plug and play replacement ecu board

full usb software tuning

switchable maps

uses all factory sensors

built in map sensor

boost control

launch control

antilag

built in factory base map for local fuel

australian built with full support and warranty

much much more

Cost will be around $1650 . Although more than a base powerfc , if you add up boost controller , map sensor or AFM upgrade and laptop software for PFC its pretty competitive - a 2nd hand rb25 power fc and decent electronic boost controller is probably more.

Were hoping to have the 1st units early next week and we will be carrying them in stock.

I am posting here as I think its pretty big news given the lack of power fc options for rb25/20. If any mods think that's not appropriate feel free to move to the sponsor sale section and my apologies.

Hey there just wondering where i can buy this ECU? Im from NSW

Cheers

Hey guys, just thought i say a big thanks to Alistair and Lumpy for the time and effort they put in this weekend with tuning my car. It goes great and is nice and drivable now. A job well done.

    • 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  
    • Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..
    • I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
