ACD Question
Robevo is armchair quarterbacking, like usual. It's his MO.
Just ignore him and your experience will be better. He only brings his one sided personal experience (by way of his tuner since he does no tuning himself) into arguments.
Example, Why would the OP need the added expense and hassle of a standalone ACD computer when the OEM ACD controller with custom reflash (Three selectable map modes) would serve his needs perfectly?

My personal experience is definitely MUCH bigger then yours in the field where actually the product is used, and not on the dyno... So might some people who actually racing will care what i have to say after my experience in BOTH world (stock and after market). Tuner opinion is one thing , the racer opinion is another. Not bad to hear both, for those who dont want to by twice.
MY stock ecu was tuned many tuners ( all the big names) here in tri-state area , and none one get it right, there was always something come up... The comment was , that is a most we can do with a STOCK ecu...
Now i got the after market one and car works as a charm , besides the fact is much better power band and power( i know it is a build engine but there is 0 issue with the engine) . How it get there i dont care, and dont know (since i am not a tuner), what i know is since i have a Gems the car runs much better in racing conditions.
So you can ignore me , i mentioned after market ecu's as an OPTIONs only if the stock ACD ecu is not enough, which some one actually already mentioned it. He got tuned and doesn't work sufficient for him.
Maybe you never did or never will meet someone who actually will be the stage where the stock ecu's are not good enough. Which is not end of the world , but after some level you have to buy these. You think all the racers like to spend that much money if that wouldn't be that much better? LOL
The Gems ACD ECU is a direct plug and play and it comes with a full tuned ACD ECU (basic tune which is 100 times better then ANY acd tune you can put up) which is includes:
" Fits into standard EVO wiring
Uses all standard EVO sensors
Connects to GWv4 software for complete customisation
SPECIFICATIONS
5 Modes of operation: Off, Gravel, Snow, Tarmac, Lock
Start, Handbrake, Footbrake, Accel, Deccel"
Worst part is, you are probably a tuner.
To the original poster, you can listen to the stock ecu tuners and stay on stock ecu as i said before, but if that is not efficient because your driving skill or the car level exceeds it, there is other better options out there.
Its a shame i have to actually argue and get attacked by "tuners " about this.
You pick what you want, and this guy razorlab keeps continuously attacking me, long time know... And i dont even know who the hell is he... LOL
But i never met him on track for sure or at the dyno...
That all i have to say here.

The best solution is here to have a Motec - Gems or Ralliart acd ecu put it in the car. And properly tuned.
Those give you easyly seconds per laps just alone...
The stock flashed is a same as the stock engine ecu tune. They both work great, but will never catch up to those ecu's in racing. They don't even have , since they weren't designed to be a serious race equipment.

these are the comments i made on this subject before i got attacked... its funny actually it happened ,and some of them is a "tuner"...
I've run the Gruppe-S reflash without the TRE rear diff... AND with it.
The gruppe-S reflash doesn't completely get rid of the clunky power transfer, but it's an improvement over stock.
I will be using Matthew Manke's ACD tuning services next year.
You can email him for ACD tunes @ support@acd-tuning.com
I think he'll be able to give you a better setup than the Gruppe-S reflash...until I actually test it I won't know, but it sounds very promising.

Thanks for taking it a right way....
There is no true ALS written on stock ecu as far as i know of . aprox a last month was a last time we were talked about it.
actually i am the end user of this products , so i actually can tell the difference from the car feed back and race results.
I am not here to shine myself to get my right go trough, you take it or leave it.

OK, so what I was seeing/feeling exaggerated by the wet track conditions is what I thought it was, the OEM ACD programming being late/slow with the rear power transfer. I could make it transfer sooner by some heavy right foot action, but then it sorta slams on and the rear end steps out (at least on the wet course).
Reviewing now, I can see where this relates to normal track conditions. After the rear diff upgrade, the drive off the corner (after apex, rolling into high throttle) was night and day better. But on the entry to the corner under maintenance throttle the car still feels pushy at times. I suspect this is the lack of rear drive under those conditions. Seems most prevalent on things like longer sweeping entrys where you are just working light throttle.
So now I need to investigate reflash options. I suspect there is a lot of time to be gained with some better ACD programming.

Maybe that is why i got attacked by other tuners here form the states ... LOL Kind of understandable.
but end of the day he will provide you a countless times tested and proven maps for your needs and for your set up. He is not a guessing game.
No one's attacking you - I just returned from Afghanistan and "attacking" would be say, getting rocketed or shot at. Please don't turn this thread into a flame thread, so people like me and others, can get some useful information out of it.
Thanks.
And what's with the posting 5 times in a row? Now now, that's bad forum etiquette
i never said i am an engineer, i said i am using it as a driver different people tunes parts on a same car....So i gathering experience with it ... which is i share for those who ask.
This is a forum so i try to help for the folks who spend money to find a best solution for they money. I am not here to try to get more business for some tuners for they products. they do fine without me
Anyway end of the day, you doesnt have a stock ECU in your car... LOL
Can you give me some info on that ALS?
They said will post it if it will work as a true ALS.
how it works? Like, how much boost it makes at idle, does it shuts off if it runs too long, etc?

I'm trying to read through this thread for some useful information, as I have a Gruppe-S ACD Reflash sitting on my desk right now. Wanted to get some more info on it and other opions before I install it.

I try to help in the first 2 comments...
Thanks for the etiquette lesson, i learned to answer to the comments which was directed to me, I cant help on that, i brought it from home.
And actually posted 4 times in a row. If you read my first two post there is all your answer, actually from the race track and from my and others experience, from acd ecu (stock and stock tuned) and after market.
i am not sure who else has this so far in this thread....
So dont worry this was my last post here.

Call Aaron @ English and ask him about it. I know he's had it working for at least 9 months.
Mychailo can edit it further to make additional tables and add logic... Just like the motec and vipec do.

sorry if "I" ruined the thread. I am not sure what Afghanistan has to do with this thread...

I look forward to reading more information pertaining to OP's question.
This will also be my last post in this thread.
I run the gruppe-s race reflash on an oem rear diff. I have noticed it does lock better then stock, but as of this last season to get my car to rotate I was still focusing on suspension set up and weight management. The more developed my skills have become behind the wheel the more I realize I can get the car to work for me be working the gas and brake and manage all the weight of the car.
I am having the rear diff rebuilt this winter for next season so I can really set the car up between the diff, suspension, and driver control.

Oy lol. Anyways it boils down to your pref and your tuner accessibility. If you had a top Motec or GEMS tuner that came to every track event then ya it may be worth the investment because you'd get your money's worth at each track with the fine tuning and just focused on driving. For the CLUB racer it may be more worthwhile to try the hacks to the standard ECU's and see what happens. You cannot admit that we haven't come LEAPS and BOUNDS with the standard ECU. I mean my god, we can do 100x with our stock ECU as most other sports cars can do that are forced to upgrade. If your at Rob's or DaveK's level and rally racing for real, it is likely worth the aftermarket ACD to get 100% and $ out of your ACD system. However if your at the club NASA/SCCA tarmac only level it's a very doable option to get your ACD tuned, much like your ECU is already.
Because at the end of the day the hardware is only as good as the software, else is only as good as the programmer, if/else is always smarter as the user or driver in this case.

I just had my first wet track day yesterday.... I have the 12-plate rear as well, and i was on Starspec street tires.... Man o man i had nothing but oversteer lol, if i got on the throttle at all the rear was walking... I even turned my ACD to gravel mode on session 2 and i was alot faster, less rear end walk... But i would suggest to u an ACD re-flash.. I'll be doing the same soon. U can choose ur own parameters as well.. I am gonna do full race, street, and the stock gravel
Let's put it this way. No acd reflash and I did fwd burnouts while understeering off the track. Acd flash made me do one tire fires on my inside rear on corner exit. Acd flash plus tre rear diff resulted in my right foot directly controlling the yaw of the car. Nuf said. I think the tre diff is the answer most of you are looking for. I too did the acd flash first, but I feel it was NOT the solution I needed or wanted.
