Would you guys be interested in something like this? Street price would be about $350ish.

Evo ACD (active diff controller)
The ACD is a replacement controller for the Lancer Evo 7/8/9 active diff system. It uses all the same sensors and valves as the original system but uses a completely new strategy. The ACD is a hydraullically controlled system using a small electric pump the product reservoir pressure and a proportional control valve to adjust the controlling pressure. The control pressure is controlled by the wheel speeds, handbrake, footbrake and throttle postition. In addition there are 5 modes of operation: Off, Gravel, Snow Tarmac and Lock.

Pretty much an EMS for your ACD.

Open would probably make the rear wheels spin more since you have less traction (less weight) back there. Which ever wheels have the least traction will spin with an open diff.

If you have no ACD to control, then an ACD controller probably wont help much.

what are the splits for all 5 settings?


It seems programmable somewhat. Here are some instructions for it.

Control Strategy
OFF Cal
There are 5 CAL modes ( refered to as the Cal )of operation 3 active modes OFF and
LOCK mode.
On power up the CAL mode is set by the Default Mode option.
The values of the Default Mode option are: 0 off
10 Gravel
20 Snow
30 Tarmac
40 Lock

Each mode is selected in turn by pressing and releasing the CAL button. OFF Cal is
indicated by all three of the Cal LEDS on the dash board are off. In OFF Cal the
accumulator pump is switched off.

LOCK Cal
LOCK Cal is indicated by all three mode LEDs being on. In LOCK the demanded
pressure is set by the LockPRS option. The hand brake can be set to release the lock
pressure if the Hbrk in lock option is set to ON, in which case the demand pressure
will be set by the Handbrake press option when the handbrake is operated.
Active Cals
The 3 Active Cals Tarmac Gravel Snow are selected in turn by pressing and releasing
the CAL button. The relevent LED is illuminate to idicate which mode is selected.
In the active modes the strategy is the same in each mode but the active regime
calibrations can be different .
There 5 regimes, START, HANDBRAKE, FOOTBRAKE, ACCEL and DECCEL.
The current regime is determined by the various system inputs.

START
Regime = 36
The Start regime is selected if the average wheel speed is 0 KPH for 5 seconds.
The Start regime is exited when average wheel speed is >STARTspd option
In the Start regime the control pressure is set by the Start Prs table . This table has
TPSVAL as an input and CNT_DEM pressure as an output. There are 11 sites
covering the TPSVAL range of 0-100 % in 10% steps. The control pressure can be set
from 0 to 25 bar.
The Handbrake can interrupt the Start regime if the Hbrk in Start option is on
The Start regime is disabled if STARTspd option =0

HAND BRAKE
Regime = 12
The Handbrake regime is selected if the hand brake switch is activated by pulling the
hand brake leaver. In the Hand brake regime Demand is set by the Handbrake press
option .

FOOT BRAKE
Regime = 20
The Foot Brake regime is selected if the Brake lights are On ,the Throtle < TPS left
foot brake option.(Throttle position for left foot braking) and the Hand brake is not
operated. In Foot brake regime is set by the FBRKprs option. This can be set from 0
to 25 bar.

DECCEL
Regime =24
The Deccel regime is selected if none of the above regimes are selected and the
Throttle < CDCLTPS option. In the Deccel regime the pressure is set by one of 3 3D
look up tables ( SnowD GravelD and TarmacD ) which table is used is set by the
mode. The mode is set by pressing the Mode switch on the dash board.
The Deccel look up table has input axis for Slip and Average Wheel Speed (KPH).
Slip is the difference between Average front wheel RPM and Average rear wheel
RPM (Fastest – Slowest ).
The Average wheel speed axis has 8 sites and each site can be to a KPH value of 0 to
255 KPH. (Site 0 must be the slowest and site 7 the fastest). The Slip axis has 5 sites
and starts at 0 with steps set by the RPMSTEP option.
Each site in the table can be set to a Demand value of 0 – 25 bar.

ACCEL
Regime = 28
The Accel regime is selected if none of the above regimes are selected and the
TPSVAL > CACLTPS option. In the Accel regime the pressure is set by one of 3 3D
look up tables ( SnowA GravelA and TarmacA ) which table is used is set by the
mode. The mode is set by pressing the Mode switch on the dash board.
The Accel look up table has input axis for Slip and Average Wheel Speed (KPH).
Slip is the difference between Average front wheel RPM and Average rear wheel
RPM (Fastest – Slowest ).
The Average wheel speed axis has 8 sites and each site can be to a KPH value of 0 to
255 KPH. (Site 0 must be the slowest and site 7 the fastest). The Slip axis has 5 sites
and starts at 0 with steps set by the RPMSTEP option.
Each site in the table can be set to a CNT_DEM value of 0 – 25 bar.

Settings
There are 6 3D look up tables, 3 2D look Up tables, 11 Calibration options and 7
Control options. Which are all user programmable and must be set for the Control
Strategy to work correctly.
The Calibration options set the non control related features of the system

Sounds like its semi-user-programmable... Am I correct? If so, would it be something simple like connecting it to a laptop via a serial port/obd port?

Also at the 350 price point that would make it significantly cheaper than the as-of-now-non-existant Shivnu user-programable ACD controller and I think thats still alot cheaper than the Motec version as well..

Edit: And isn't 255kph a bit low as a speed cap? Dont you guys hit faster than that in your shop car?

mike..... what does this all mean for the daily driver?

Mike W
09-29-2006, 02:28 PM
Yes programmable parameters and options and stuff. Interface like an AEM EMS.

255 kph is just the limits of the control. You would have the same functions and settings at 255 kph as you would at 300 and 350 maybe. I would think you could live with that. If anyone has a problem with it I am sure we could come up with a work aound.

Daily driver? It only works and does tricks when wheels are slipping and spinning and sliding sidewards and stuff. For me yes that is a daily driver. I dun know about you though.

Right, I know that part. But what can it do when the wheels are slipping and spinning, etc? It sounds like it would be beneficial but i don't have experience with any type of EMS. Can it make the car slide more rwd style, etc, etc?

Mike W
09-29-2006, 04:20 PM
With it at full open the rear wheels will spin more. Yes you could make it do that.

Evasive motorsports sells the what appears to be a fixed preprogrammed ACD controller but I went to Garage HRS's (Cyber Evo Fame) and saw this one that appears to be programmable but not sure if it is for our EvoIX

Someone should buy one and let us know how/if it works :grin:

Anyway the translation is from google so it's kinda rough* (taken from Garagehrs.com)

http://www.garagehrs.com/cyberevo/acd-selecter0.JPG

- The ACD selector it upgraded! -
Expanding the variable range of force of constraint until recently from the model
It is possible to make various travelling conditions conform,

As for kit contents such feeling (as for ECU unit it is normal trade-in)

●CyberEVO ACD selector -> price reform schedule (the various and including tax for [ebo] 7~9 ACD)
* Normal unit trade-in

The part which is suitable to the initial of the mechanical cable type diff. of ACD the program of 10 types which are installed beforehand ACD-ECU (4WD-ECU) by writing, can be changed in 9 stages.

Because this and the mode selection the program of 30 types can be tested together, you think that it can cover the taste of most drivers.

Actually you have used even on site of rally, gymkhana and the circuit, but because instantaneously it can set can modify at that place according to circumstance, it contributed to time rise largely.

As for ACD-ECU which [saibaebo] has marketed also the part where other than of the initial is small is modified, but the effect is tremendous even only initial modification.

Because you insert also the normal data in program number 0, also normal return is possible directly.

In other words [saibaebo] ACD the data has modified in addition to the initial suitable part, but this commodity does not fumble the part of that. The tar Mack of normal, it becomes control of 3 modes of the gravel and the snow. Because as for the respective mode control differs, if 10 types there is a data of the initial suitable part, the number of programs means 30. It is the case that it keeps rewriting the program of 30 types according to circumstance.

When 噛 you see and shatter and say for example we assume that program number 1 was written. When it does, because tar Mack, three mode all initial suitable parts of the gravel and the snow change, 3 types it is the case that it can be tried.

It reaches the point where you can set the electronic control part by your. As for this being epoch-making, the shank.

* ACD-ECU is removed to rewriting.
* The person who is used for competition please inquires in regard to verification such as regulation.



1.ACD selector picture


2. Force of constraint of the diff. is chosen, the setting start button just is pushed


3. In indication of entry OK is cod completion
