For the UK guys having a lot of experience, i was wondering why they open the valve as low in the load range as they do.?

Maikumaru

simple answer: you won't activate it as often with higher load. air is injected when the parameters are met coupled with throttle lift off.

I am not sure what my settings are, but I ll say if it is more than 20% load and over 2500 rpm at lift off...air is injected. that mixes with the negative timing that is already happening

No the trigger load is an under load value. Thats what im saying you should open the valve higher in the load range after criteria met. Increasing the force of bypass air. Am i seeing that wrong?

Maikumaru

Yes you are. All you are doing is determining minimum criteria to open SAS valve.
load and RPM are criteria for opening SAS valve.

if you set load factor at 100/max etc then it will only open after such a load is met when you lift off the throttle...

To kinda answer your question in a different way;
if you apply max load (with right foot), and lift off, there is a much more impressive result than just feathering...

We tried to set load at 0 hoping that it would hold a little boost at idle etc (didnt work).

when you get everything installed, get the SAS solenoid pinned into the ECU, and ECU flashed. you will have to screw around with it. We have been screwing around with this for a few years now, and biggest limiting factor for stock ecu is lack of negative timing....and I will add (personally) lack of consistent negative timing.

Thats why i thought it was opened under x load

Not talking about min load table..

But you're def right there will be some screwing woth it for sure!

Maikumaru

Ah if you are looking there then you are right spot.

I am not sure we are talking about same thing however;
The valve does not open when throttle is depressed...when you reach X load and release, air is injected (coupled with a few other factors).

You can set the load high...however it wont turn on until you reach whatever criteria you set.
Basically if you want it to actuate often (low rpm)...keep the criteria for opening sas valve low.


(from geekmapped)
Minimum vehicle speed:
Is just that you will need to be doing Xmph for the ALS system to start working.
Minimum RPM:
Again you need to reach the set limit for it to work.
Minimum Load:
You need to go over this load for it to work.

Well I started on the ecu stuff for my car tonight. Two things came about: I do not understand the version of the rom that donner linked me. 88586714, is a DMA speed density rom. I dont need the complexitty of DMA and the patience to set it up. Also I couldnt find specifically the 3dve table in that rom. It does not show up for me?

I also cannot find the 88580714/5 v7 rom with XML. The link in the v7 thread was dead.

I lost all my old files due to a hd failure, so im starting out all fresh again.

Can a DMA rom be tuned just like a normal rom? And will the regular altmaps switch work?

You don't need to use DMA functions but when tuning big 3d VE map you should To use it as normal rom just set all pointers to rom addresses.

Download 88586714 rom with xml's from www.petterimutteri.fi

I can guve that a shot .. the dma.. Also no sas tables are defined. I couldnt locate. 88580015, 88580715 xml. The v7 thread link was dead

Twas late, ill sift thru tonight again

Im not with my laptop niw, but are there any prerequisites i need or should your 88586 xml be everything?

donner

iTrader: (1)

Everything you need comes in that package but also some other xml's are needed (comes with Ecuflash).

Id also assume i could take thw defs for sas from a 8858 rom and apply them to tge 8856 or did sd/dma take that space?

Wierd issues lol.. im on a fresh download of ecuflash 1.42

Id like to find the v7 8858 rom if i could too. That would get me into the familiarity of sas tuning quicker.

Maikumaru, what amount of -ve timing you think would be enough to produce some decent PSIs on a stock ecu? I had previously set antilag at around 5-6psi with an average of -23/-25 timing on a standalone ecu (with a throttle kick).

Maikumaru

I dont use throttle kick, and I believe my timing is something slightly above -20ish.
(I could be wrong havnt checked on settings in over a year)

I am guessing you need -30 to do decent work.

I am not sure on the PSI since my boost is measured at throttle body...I will switch to turbo housing tap in point though as I am very curious to what stock ECU is actually doing.

stock ecu does not allow for boost to be held at idle...
I am sure it does something, but have no numbers to show...

plus switching to standalone so need to prepare etc.

I still havent been able to find the 3dve table, or SAS tables in the 88586714 rom. I have the 88582714 v7 88586 v7 xml. Any thoughts donner?
