I'm not sure if antilag fuel could be measured through a wideband. I imagine that a standalone software could provide significant fueling through ignition cut & average of -35 timing.

It would be great if we have the software of any bypass system/ecu to analyze, we would know what it takes to get this to work.

Would something like the attached photo work if done in a full OL mode?

I did try something like that before. I pointed out the min afr value table that caps it at 8 something .

I will try many things over having better hardware

I would have to research what ecu the btcc wtcc etc cars use.

I think it's syvecs afaik

Also my take on this is to reduce lag after boost threshold. So like 3500-4000 rpm to redline. I won't focus on the hard to make boost in areas until I see what happens in the max response areas.

I am trying to get a turbo speed sensor also which is key.

motec system exhaust.. i wonder what that is.

some discussion of ecu's and what is used by ALMS and WTCC is briefly brought up

I have a throttle kick style als on my Galant and secondary air injection als on my S13.

Both are great options and work well.

AFR wise both systems are similar, you will find there is actually a wide range of afr's that will support antilag its a matter of finding what works but does not melt or destroy things.

Throttle kick ALS has down falls (no or LOW vacuum means no power brakes. Throttle kick ALS almost always needs ignition retard vs cut which puts heat and stress on the exhaust valves/head.)

Secondary air injection ALS is a bit trickier requiring some extra solenoids, lines and boost or vacuum chamber to control the valve but allows the majority of the heat/combustion to happen in the exhaust manifold. You can also usually get away with using ignition cut vs retard which helps relieve some stress from the head/valves.

Hey Tunermt, so, I'm right in concluding that sas als doesn't require a throttle kick? I don't know of any standalone ecu type that offers sas ALS as an option, so, it would be great if you could post detailed information regarding the setup you have on your S13:
What kind of ecu are you using?
Amount of boost the system is producing?
Ignition & fuel settings?

The seller failed to mention a very warped manifold flange and some cracking going on. Regardless ill work it into shape and if and when the need arises I will remake the getup .

Those holes are 1/2" I'm looking for 5/8 so they will get bumped up a little bigger.. Then I will have to mount the manifold and have tubes bent

Cracking already! Not the best mani for ALS I guess :]
What ever happened to the oem sas mani you had?

I have one already

I feel there's not enough flow from that set up. I'm goin all out this time

I run an AEM V1 in my S13 and AEM V2 in my Galant. Sharing fuel and timing settings won't be something to helpful as there are many variables and it would not be ok to attempt to use the values in another application. I will say my the combustion happening in my manifold is very lean to keep temps down.
For anyone attempting to set up or tune this type of set up i strongly recommend having a couple EGT gauges 1 pre and 1 post turbo so you can keep an eye on things.
Dependent on your Secondary air injection set up and how you want your ALS to work a throttle kick may or may not be needed (I do not use a throttle kick on my secondary air injection set up)

Undrtstably enough about not using your settings but giving an idea of raw ipw + injector size wouldn't hurt. Assuming reasonable fuel pressure too.

Either way I'm starting on my set up and in a couple of weeks should be mocked up.

I'm poking at the idea if dropping back to a maf so I can monitor airflow hz while not on the throttle

A log of hz while no sas valve active should be able to be compared to a log of hz while active to get a good idea of airflow

Depends on the TSS stuff whether or not downtime is an issue

I took a spin at making the Arduino I have some code..

The thing I want this for, is in case the ecu likes to hold the sas pin on even though the throttle has been re applied. This will use both tps, and evosaspin state to determine alt map activation and sas solenoid activation. This seems to allow room to grow the code some and read the frequency signal perhaps from the TSS kit and convert to analog so I can log that . Plus use a speed modifier in the code.
