Awesome.. I would prefer the best fitment possible for this adventure.. lmk

From the geekmapped you can download the Group N Evo5-6 roms but the SAS control is the same as in the JDM Evo 9 or Evo 9 RS .
I tuned Evo 9 RS with working OEM SAS + add ignition retard . Sound like different without SAS and only ignition retard but at all can't build boost or achieve 0 bar .

Motec M800 is great Ecu with a lot of working motorsport options ! One of the best but expensive !Originally Posted by foxbat
M800 is a good ecu, but I had it with Motec & their poor product support, I might consider something with knock control like AEM.

However if we can get 1 timing map from any where to use in the rom, such as EGR timing map, or alt map, or launch map, strictly to switch to when tps is less than an adjustable percentage it would be a huge start to making this evo ecu a little more capable. granted we cant do true idle antilag cyclic etc blah, we or atleast I am not asking for that. Im interested in the ability to hold boost on overrun, for an amount of time which would come from the 8858 sas capable rom. We would be able to use ADC0F switching to switch to alt maps and get fuel and timing too. The possibility is there. We just have to chose a channel to output a set voltage, and when its triggered by overrun condition, or maybe in the 8858 rom it can be switched to the overrun timing map when it goes to sas mode. Somone has to be able to accomplish this. And Im still making it stand that if JB can do it with a USDM rom and use the bcs map to activate, then it would be worth looking into this with a rom that has the adjustability we could actually use!
ecu gods, is any of this other than impossible?
I think I just have to achieve a voltage output from the ecu that dictates when tps is below a certain % that a certain voltage is applied, if I put enough thought into this im sure I could hack it? Then it would switch to alt maps or now "overrun maps" and such.

Switch able ALS is perfect.. yes the EGR timing map mabye a good idea for Antilag timing map with TPS/RPM !
What I never seen on stock Mitsu ecu is capable for Ignition cut..
Here is picture what I posted earlier what is need for ALS :
everything is shouldbe possible with stock ecu as we see what Tephra roms can do ! Only problem with the Ignition cut
The Evo X Ecu is better because the Electric TB is there for air in ALS mode .

gr.n and a cars at the time used gems ecu, not white case ralliart ecu(that was cheaper solution and just reduced spool time , no pressure)

Confirmed as different, only slightly though... on the 9 the sas valve is inverted. I examined it & a previous generation sas could easily fit with some minor modifications.Originally Posted by 211ratsbud

True, gems was & still widely used in rally cars, but I've read that these E6s group-a had an E1/2/3 based ecu (metal casing) these cars had enlarged SAS & knock control, with both we would need a factory ecu to operate.Originally Posted by claudiumxg

What about the group_n rom? http://www.geekmapped.com/forums/showthread.php?t=2776
was it ALS capable?

no, that rom is from white ralliart ecu, no als in the curent conceptionOriginally Posted by foxbat

Well, as it seems the slight difference, I could make totally due with a set of piping and the sas valve. if you had those readily available let me know! I can always buy the gtspec/map short runner type manifold that bolts directly to SAS equipped cars.
Let me just emphasize, that I am months away from having my car back on the road because of winter. If I could wait and get an entire parts list from a evo IX, than it would be my preference.
So is it the consensus, that having a set of fuel and timing maps that takes effect during overrun would be a best route for achieving boost on overrun? You could have identical fuel and timing map resolution by using either alt maps, or launch maps. Control timing and fuel finitely by load. Thoughts? Im in for 88580714 lol
I am still thinking that there is a way to achieve map switching on overrun with minimal patch work. There must be an internal location we can use to trigger a switch to alt/launch maps based on the current map switching ability of the roms?
given that there is a load stipulation for alt maps, and a speed and tps for launch maps would it make any more sense to focus on using launch maps to create the overrun map based on launch maps vs alt map? I would be ok with losing launch maps because the factory 5000 rpm limiter is already enough to break my 255's loose during a launch.

Probably been mentioned but thought of using the tables that cause the 'throttle hang' issue people tune out? There are 3 tables associated with that issue, all in ISCV control. After certain conditions are satisfied (ie over 4500rpm >170 load >12mph) the ISCV table requests a certain % that in normal operation causes throttle hang. Could this be used as a sort of throttle kicker to increase the ALS effect?
With SAS system alone and 6mm banjo bolts I can get crackles/pops but no positive pressure at all, in fact it remains well in vacuum.

Heres how Im thining to implement alt maps.
Boost at idle is not something I would be worried about strictly overrun/throttle lift situations. I would even have FFS enabled, only to use boost on overrun where the situation would call for a reduction in throttle input. I believe that this feature would be very handy for autocross where the lifted throttle duration is relatively short, and this may be less advantageous for true roadcourse applications because of sustained deceleration. I am not sure about EGT during extened overrun situations.

Nice idea, and the wireing diagram is valid.
Does pin 64 have an internal pullup/pulldown resistor?

No idea i modified jot diagram.
What is the function of a pull up pull down resistor.

This is the most feasable option yet. I need somone to tell me if the 8858 vs 8859 roms share the same adc0f input. thanks!
I can test map switching with the car not even running i suppose. I will order a map switching harness from buschur racing, and just add the switch! In cabin is probably the best idea considering that radioshack switch is likely not weather proof.
piping valve and canister are being worked on. I wish I could have this stuff like NOW!
