Really the only thing the flash can do is change the voltage that the pump sees to alter how fast it locks up. Until they tell you flat out what voltage it sees and when i would not be interested in paying for anything.

There are cheaper options out there, such as rewiring the pump yourself. (I realize for tracking a car this is not the best option, but for drag racing it sure as hell is (short of removing the acd))

 

I agree with you for the most part. I have a feeling though we won't see that info for a simple reason...somebody else copying them. How many tuners show off their timing maps or some tricks they do to gain hp? Its the same principle.

 

You have a point, but from my point of view i would never get a tune from someone and not see those maps... map that is just me.

I have a feeling that if everyone were to wait for a few months there will be alot more/ maybe better options out there.

 

Well Billy i somewhat agree... I am not that versed in the workings of the ACD, but since it is a hydraulic system, there has to be an actuator also, this is probably what they are altering the voltage to, and most likey the actual trigger pulses entering the actuators... we definitely need some more info on the actualy physical characteristics of what the flash is doing...

 

I know that rewiring the pump has been done before for drag racing, but i am also not that well versed in the working of the acd.

 

Ralliart also sells different ACD controllers. In road racing you definately would not want to have a full time lock, as you turn your track isn't the same. Something has to give somewhere.

 

Well I understand why it would be reqired for drag racing... you never have to turn so the wheel are pretty much gonna spin at the same rate all the time. Road racing or autocross no cause of the tight radius turns the front wheels will have a longer distance to travel than the rears... They are probably changing the voltage and clamping times for the ACD clutch actuator in order to speed up/keep the diff locked quicker and longer for added grip...

 

Theoretically it should still be open when turning just lock faster when it needs to. I don't think it makes it full time locking unless you specify the full out race unit. Not really sure myself though.

 

My 03 VIII won't get any of that love. Tephra is screwing with diff software - won't be long until we can do it ourselves - no Gruppe-S needed.

 

^My thoughts exactly...

 

but how will we test this?
I'm sure Gruppe-s has some testing behind their acd "tunes"

it's gonna be a while till we actually get some good resources behind the project and get good setups. Or we could just have everyone customize it themselves to how they like it

 

There is car car in Washington that testing is about to began on.... have a little patience

 

oh rally? That's pretty awesome.....

 

With who's ACD flash?

 

Custom english racing ACD tune!?!?!?!?
