hey guys, I might have missed a few things in the discussion, but I figured out how to run the LC and not have the AntiLag be a pain in the ass.

Just tuned one of the shop cars to a conservative 417whp (because all tunes with published numbers are "conservative" right?) on 20psi on pump gas @ 10.8-11.0 AFR. Wonderfully smooth car to drive now and the boost is right there on a shift instead of waiting for the turbo to come back. Which is really awesome because the 35R turbo has a 1.06 A/R turbine housing. Good bye MAF!!

The antilag isn't activated unless you exceed 5200 rpm. The LC is at 5600 and the anti lag will clear if you get less than 3000 rpm. So essentially, it is only used when you punch it and won't come in during normal daily driving.

What did you do to get the LC to work? It didn't on my 02 WRX.

Has anyone figured out the CEL yet?

today was my first day working with this rom so I haven't even addressed the CELs yet. Getting the car to run right was my priority.

There were a handful of changes to make... I'll try to take some screen shots and post them up.

Give me a couple minutes.

Does this ROM use ignition cut for the LC, if so, can someone post a vid?

I'm almost positive LC just uses fuel cut.

I've gotten LC to work 100% independently of AL - but unfortunately its "always" on - the speed threshold for some reason does not work when I use it separate of AL.

Anyway it should be independently ran soon.

What are your "Base Timing Idle (Group-N Mode)" settings at?

Basically the anti-lag is not a rotational style anti-lag - its simply ignition retard mixed with ignition cut/fuel cut @ the same time while holding a set engine speed.

Changing ^^ table up there too all positive will basically remove the effects of anti-lag. A few other little things that happen as well, which is why we are trying to make it a VERY simple LC that does not involve any of the other little things that happen (that you may/may not be able to tell) - excessively high ISCV duty, separate idle map - few other little annoying things.


Also running a mode byte of 136 does away with per gear comps - which are being determined if they are actually even going to work on a USDM ecu at the moment.

I can't wait till I have the car back up and running in spring to test some of this stuff out some more! Jerod and Andy keep up the hard work,(I am hoping for somekind of way to get antilag working for real without a prodrive throttlebody to spool this big snail up...Maybe fabbing up something custom even ) I have already added the idle control/nps inverter functions to my definitions...Can't wait for more!

I don't think you are hearing me.

Drive the car normal and stay below 5200 and the antilag is NOT active.
Put it above 5200 will activate the antilag and it will stay activated as long as you stay above 2700 rpm. Going below 2700 deactivates the antilag again.

It's pretty obvious when the antilag is active.

Maxwell is the anti lag, antilaging lol ? If so nice! I dont think our throttle body is made right to do it how they(subaru/group n) intended but if it works a little...

yes, in fact, it works great. No more waiting for the boost to come back during a shift with this 1.06 hot side.

It was so active, my secretary came running into the dyno room worried something was on fire.

Nice I am going with a 1.00 hot side so that is good to hear , what turbo if you dont mind me asking?

Either way

Thanks I'll try your settings soon. I have to put a better clutch disc in my car first. Last time out it was driving through the clutch coming off LC on my MAF ROM with the LC patch. I finally make enough power to need a puck style disc.

I've had the antilag on the SD rom working on my car before. I hope this will get the LC on the SD rom working.

I wanted switchable LC, but if this works like described, there's no point. Now somebody figure how to take care of the OCV codes cel and everything is set.

The anti-lag is NOT true roational anti-lag - YES it is similar to anti-lag in its functions, but without either having a setup similar to mick's or similar to the GPN cars it will not function 100% properly.

In order for anti-lag to be 100% - you will either have to have a throttle plate stop, keeping the throttle plate open in the 1-5% area at all times or you will have to setup a throttle-bypass (IE Micks, which is SOMEWHAT similar to how GPN cars are plumbed)

Sure there is ignition and fuel cut, which is technically what anti-lag is - but you simply cannot flow enough air past your throttle body by using the ISCV itself - Don't get me wrong, you will be near atmospheric pressure or nearly in boost with no throttle, but think of the effects you will have NOT only on the turbine side of your turbo but on the compressor side.

You have a compressor that is attempting to flow air while creating boost, but there is simply no where for it to go. You will, if setup aggressive, get nasty compressor surge with anti-lag and no modification to the throttle plate. You can argue and disagree all you want but its the plain and simple truth.

Maxwell, I know exactly how the anti-lag works, your simply raising the threshold that needs to be met, which would be good for drag racing/road racing ect. Again its still not TRUE anti-lag.

WE are attempting to COMPLETELY disable the anti-lag while still retaining complete use of launch control. Meaning the user will have the option of either anti-lag, anti-lag + LC, or LC - Currently you CANNOT disable anti-lag completely while using LC - You can:
Raise the threshold, as you have done .
Raise GPN timing to above - values which would defeat the general idea of anti-lag, and basically once AL threshold was met the car would idle @ that rpm with possitive timing (AL is running - timing with both timing and fuel cut mixed in)

I DONT want anti-lag, I know and have seen the short/long term side effects (if it makes it long term) - Ignition cut on Shim/bucket valvetrain will make VERY VERY VERY short work of the top end. That is certian.

Having stiffer springs, shimless buckets, cams that are efficient where anti-lag is present will absolutely help. But you still have to consider what is going on, which most don't.

You can/WILL burn exhaust valves. Blow out Exhaust gaskets. Melt turbine wheels. Crack headers. The list goes on.

I'm not being hateful I'm just letting anyone that thinks anti-lag is cool and I want it to know of the damage AL WILL cause. Its not maybe, its a gaurentee, how long your car takes it? Who knows but I wouldn't bank on long with stock valvetrain.

SO like Max said, rasing thresholds for AL to be met can technically disable anti-lag.

Again we ARE working on LC with NO anti-lag at all.

I'll go out on a limb and say before the end of the year Andy and myself will have the modebyte feature completely defined and 100% useable for everyone.

I just figured out the ModeByte for Per Gear compensations to be present and nothing else.

To have TRUE GPN mode I believe the mode byte should be set to 255, which would TECHNICALLY enable all GPN mode variables.

Again I have not and will not test this on my car, I know better. But if someone feels ballsy set MB to 255 and take note of what is happening.

It should be set straight to OL per the idle switch, which means anything over 1.5% throttle you will be in OL. ISCV duty should be ridiculously high all the time. Per gear compensation should be active. Anti-Lag/LC should be active per your settings.

Guys, for those of you running this ROM, check http://www.romraider.com/forum/topic5577.html for new def files that will allow you to fix the high idle as well as enable LC without AL being active. More to come.

Also, per the dwell discussion a few pages ago, I am 99% sure that this ROM is using the dwell settings for the grey coil packs, not the black ones. This could potentially be burning them up much quicker than intended. Waiting on Jerod to do a little more testing and that will be released for tuning in the defs as well.

Andy
