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.
