Air alone is not bad but not good enough for proper, psi producing effect. -ve timing use is a fuel collecting measure, it's not as effective when fuel is in CL mode.
We know that group_n subies had stock ecu antilag, but do we know of such fact about group_a/group_n Evos? If yes then a developer would only need to decipher the code similar to what Jason & prior guys did with the 16bit rom.
What did Jason think? He's a good candidate since he would know what it takes to get ALS working, software wise.

 

a few months ago he said it would be a while, but he said it was in his interest. we dont know of a group n type rom for the evo by any means from what I understand. except the evo 5/6 which used a 3 type hard case or something or other. I couldnt speak what the evo 3 had for sas/als function

Maybe at the very least he could offer the transition maps, which i still believe that a mechanical fix is the very next best thing. If timing comes down to just adding in an offset then what is the big deal? there could be one table.. timing adder which is already in existence by the presence of the IAT>timing table. I run full open loop anyways my self. The proper way would be to ignore CL while SAS active, and run CL once the SAS is done.

 

group N rom is a good/great idea...but no clue if such a thing exists.
only way it will work with "stock Ecu" is if such a group N rom exists.

you can try mechanical fix, but trying to create as big as explosion possible in exhaust manifold is not the way to do it...you cant tune als adequately with stock ecu in current state. you can do the mechanical fix...but seems like that will do way more harm than good....

I have warped exhaust bits from using sas + -ve timing

I have yet to come across any Japanese or Uk person that is able to implement legit ALS on their car with stock ECU...

If you want ALS, aftermarket ECU is the only way. Im convinced of it now.
SAS helps turbo spool....does not "hold" boost

 

Ok, so with that in mind lets return to the what ecu can control air injection als question?

Ive been looking at vipec

And why was jb able to hold boost until the fuel timer expired?

 

I believe any decent aftermarket ECU can control "pin 5" or the equivalent...just requires some code writing etc.

I was looking at AEM, but cant find any UK or JPN guys who use it, or at least use it with the secondary air system. I see lots of Motec, and UK guys like Vipec.

but at 1000+, little bit prohibitive to just pick one up to give it a whirl.

Not sure how much vipec costs, but could be a good alternative, along with autronic.

I think SAS could even be used to cool down turbo if programmed correctly with standalone

JB used the tired and true throttle kick...
I suppose if you used that and used it in conjuction with secondary air, who knows what would come out of that...would be good old fashion metal melting fun



Personally, I dont want to sacrifice my car to give that a whirl.

 

I have tuned many motec equipped Evos before & I can assure you, it can't control sas, it simply doesn't have to, I never heard of any stand alone that do. Often, sas gets removed when cars are equipped with a stand alone.

What ECU/software did the Evo7 group-a (with offset sas) car use?
Evo 6 wrc/group-a used a metal cased evo3 ecu. Such ecu could contain the software logic needed for a sas aided ALS. A good plan could be to acquire such ecu & to send it to a developer to reverse engineer it & apply its ALS logic to various exiting evo roms.

 

that is a very good idea. Just a matter of finding one...

 

i dunno just seems like it is searching for fountain of youth, or atlantis, saskwatch or lost city of gold...

Jb used sas on Andrews car which i am speaking of. Both of them said als effect was limited by fuel timer in usdm rom. Just dont see what they do to even see positive pressure. Let alone 14..

Im not convinced its over yet. Getting closer to my sd dial in

 

Nice find!!

 

Yes, but little to no information about the ecu and functions itself.

At this point im really curious to see how the rest of the airbypass ALS was implemented.

hrmm..

its in some wrc cars.

Thinking that a valve like that on the charge piping leading to the outlet of an otherwise normal plumbed ewg except welded with 2 or 4 large runners leading to the exhaust mani and I'll have a very high flowing sas valve.

More air might mean less - timing.

Plus having a top and bottom port might be advantageous

 

Mechanical timing offset: can I just offset the cam sensor? Or do I need to adjust the reluctor on the crank too? I've been looking at the stock ecu fractional degree thread for a bit, plus a lot of stand alone ems forums. I'll end my quest when I find the answer is neither more -timing and more air

I think I can just do the cam sensor. people who adjust their exhaust cam end up with an offset correct? I just want to triple that or so haha
