Re: Rolling anti lag
Are you really advertising another ECU on the MS forum? Do you think that is helpful?

Re: Rolling anti lag
I am confused..... If this feature is already available in another system, that you apparently prefer, why are we even discussing it here?93supercoupe wrote:Just finished implementing and testing yet another ProEFI first....................................................

That is a copy and paste from another site.
Im not sure if my approach is wrong, or my wording, but i feel like im getting ALOT of resistance on a simple feature request that other systems already have. I am NOT advertising another EFI system, I am NOT a street racer, I made my point very clear, many times.
Im simply asking if we can make this feature happen in OUR system. Thats it. On page 1, people werent sure what i was asking for, so i qouted another source. thats it. I dont even know who or what Pro-EFI is.

Re: Rolling anti lag
Well your cut and paste sounded like you talking and no reference to Larry at sound performance was made
Pushing the feature won't implement it faster. Casual bump the thread with ideas rather than demanding an awnser

Re: Rolling anti lag
The most important thing here to make this happen is an explanation of how it would differ from the existing anti-lag code.

Re: Rolling anti lag
Ok,
Im thinking theres a way to make this work with what we have already.
But the problem that i see when i look at the ALS settings is that they all require a defined RPM or vehicle speed.
So your at 4000RPM, you hit the activation button, and the ECU will limit it to 4000RPM. So now you can put the pedal to the floor and build boost. Release the button, and the ECU will now let it rev out, with boost already built.
But now your traveling at 5200RPM and you wanna do the same thing. Just hit the button and the ECU limits you to 5200RPM, you can floor the throttle, build boost so when you relaese the botton, the ecu lets it rev out with boost already built.
The youtube video defines it pretty well. Its not an advertisemnt, just an example. I have never used/bought or considered what ever management system is in the video.
Basically its ALS as it is now, but the moment the activation switch is used, it takes the current RPM as its setting.

Re: Rolling anti lag
Sort of like the "Variable Launch" option, but for anti lag?

Re: Rolling anti lag
I guess i dont know the operation of variable launch well enough,and im having a hard time finding threads with application or really any documentation at all but if im thinking about it right, then you would need to have an activating switch, then a 0-5v potentiometer to determine the RPM you want it to hold at.Matt Cramer wrote:Sort of like the "Variable Launch" option, but for anti lag?
So in a sense that would work, but if we just implemented a switch that captures current RPM as its limiting RPM, it would be much easier.
hit the button, and whatever rpm you are at is now your limiter until you release the button.

Re: Rolling anti lag
and you wouldnt really need to implement any ALS settings (unless you have a massive turbo) because just being able to hold a certain RPM and having the pedal to the floor would create boost. I think.
But being able to implement the ALS settings with this would only help i suppose

Re: Rolling anti lag
Variable launch simply sets the hold RPM at whatever RPM the launch switch is engaged at.

Re: Rolling anti lag
Current variable launch in MS3 uses a potentiometer to set the limit. It works well.
I have a vague recollection that MS1 might have had a feature similar to what is discussed here where the limit RPM was grabbed from the current RPM when the switch was activated. I'll consider that for a future release.

So you would set the window of RPM (3000-6000RPM) and what ever RPM you engage the launch switch at in between those 2 RPM's is what its held at?
Where does the 0-5v potentiameter come into play?

Re: Rolling anti lag
You set up the variable launch specifying the rpm window, then on the knob you have you just find different points where each 500 or 1000 rpm difference is. In the application your wanting youd have to turn the knob to the current rpm and potentially setup a button that acts like the clutch switch
James, this is a feature I and a friend with a 1jz could use for some roll race events we attend

Sorry, had the MS3 and MS1 variable launch implementations confused.

Re: Rolling anti lag
This is how i envisioned it working. Which is fine, but requires an extra step and course adjustment.nathaninwa wrote:You set up the variable launch specifying the rpm window, then on the knob you have you just find different points where each 500 or 1000 rpm difference is.

Boom. Thats all im asking for. Thanks James

Re: Rolling anti lag
Hi James, any updates on this?
I also like to idea of the launch control that engage at the rpm value when a button was pressed.

Re: Rolling anti lag
Check out 1.4.9, it's been out since .7 or .8 under pit lane limiter, try that and see if it works for you
