PowerFC & GTST Series 2 with A-LSD (GTR Vspec diff)

[BATMBL]

Hi guys

My R33 skyline gtst series 2 is one of those lucky few that come with this factory mod, where i have the GTR vpsec diff, and therefore i have the 'slip' and 'a-lsd' lights on my tacho display.

My question is, with the power fc (new version), does anyone know if this extra factory setup will work with pfc or will pfc pick it up and control it? as the ecu must be in some way controling something im assuming, and since not many gtst's came with this, just wondering whether apexi has this inbuilt in their pfc incase a gtst like mine were to use their product?

any help greatly appreciated, as im looking to get PowerFC VERY soon, and need to know whether it will work!

thanks,

-Michael

The diff will not work sorry and your diff light will stay on.

What GTSTVSPEC do when he got the Wold 3D put in.

[paulr33]

does the bnr33 powerfc support the diff in a vspec model? im assuming it does

we are modifying the wolfs outputs to run it.

[BATMBL]

bah, damn!

i guess the only thing with it then is that the diff will run without the control of the ecu? anything bad that can happen from that, or i should ask, whats the pros/cons of that?

PaulR33,

Yep the PFC runs the A-lsd in Vspec 33's, mine works just fine...

Cheers

yeah im wondering if the power fc for gtst supports the same diff and controls it

Aren't all diffs mechanical?

[GTS-t VSPEC]

No, there are viscose diffs, like the A-LSD's which I believe use clutch packs, and a hydraulic pump. When the A-LSD isn't working it open wheels. We're planning on sending a signal to the pump to cause it to lock when we want it to.

GTR pfcs and wolfs work the ALSD on vspec GTRS but never had a GTS ALSD work with them.We tryed a GTR ECU in Pauls but the diff was still dead.

well thats not going to be that good then, if its going to open wheel, then only one wheel will spin and i'll get minimal to no traction down the quarter, as all the power will be going towards one wheel! even the normal gtst diff will be better to use than this one then...right?
