anti lag system FTW
woot i finished up modifying my megasquirt for the true antilag system and i effin love it, 2-3 seconds to build 20 psi of boost
can i use the antilag system threw a muffler? ive only tried it with my open downpipe. and the thing shoots about a 2 ft flame out of it not to mention bangs and pops insanley loud.any risk of blowing up the muffler case?
and what would u guys think a safe max turbine temp would be,im going to install an egt probe right before the turbo inlet to monitor the temps to make sure i dont get things to hot

Re: anti lag system FTW
obviously unburnt fuel collecting in the muffler wouldn't be a good idea when it finally lights off.

Re: anti lag system FTW
im aware of that but with the muffler being at the end of the ex system i dont think it would coolect any unburnt fuel,since it pretty much all gets burnt pre turbine.but i can see the system maybe building presure up inside the ex system

Re: anti lag system FTW
Sounds like a typical timing retard and rich fuel to spool it. Did you try turning off the antilag and see how it spools? Maybe you don't need that much fuel and timing reduction. Keep in mind that beats on the exhaust valves.
What size turbine is on that to need the antilag ECM option enabled?

Re: anti lag system FTW
I was just going to ask, what is "antilag" option? Is it only for the first split second of throttle actuation ?
If it is just rich fuel and retarded timing, it will blow your muffler apart. That's a time tested fact - we call it muffler explosions in our industry, and it's extremely dangerous.
1) Run it with no piping at all (current)
2) explore without the anti-lag option.

Re: anti lag system FTW
its got a small turbine on it right now, ptrim wheel with a t3 .63 housing, im planing ahead for the larger 1.x housing on the 74mm turbo.
on the foot brake i can only get 9psi without the antilag before the brakes wont hold, i can set the antilag so far below my 4k converter that this thing would build boost as high as i have the wastegate,deff gonna make for some fun launches.
and yes im using -10* of ignition timing + an additional 25% fuel
tell ya one thing it makes for one great fire and sound show
----------
i do knwo alot of the import guys run them with mufflers but there running them dam stright threw mufflers,prettu much the same thing as one of those red cherry bombs, im looking to bolt an adjustable borla catback on the car

Re: anti lag system FTW
my soft limit is set at 2,800 rpms, and the hardlimit is set to 3,300
when the motor is brought upto 2,800 rpms it starts to add extra fuel and retard the timing.
it will continue to do this till 3,300 rpms at which point it acts like a full out revlimit and starts droping sparks.
during this time i will have rolle dinto the stage beams,light goes green u let go of the brake and antilag button and ur off.
on a stick shift car instead of a push button u could wire it to the clutch switch, though an arming switch so u could deactivate it.but everytime u changed gears u could have the antilag system activate and keep the turbo spooled between shifts
very useful in drag applications, but very hard on turbos and ex valves/headers.

sounds like ur talkin bout a two step, stutter box etc....
I have a MS which one do you have and how do you have it set up in megatune?

Re: anti lag system FTW
I cant find anything close....
also on a side note when ever i try to load a file set up for MS II code megatune gives me an error and asks if i wanna kill the program, if i do it closes if i say no it opens mega tune but megatune runs slow

Re: anti lag system FTW
well i dont have a transbrake as an option unfortunatley, but yes they could give the same results but, with an antilag system u could run a massive hotside. put it this way with a transbrake and 2 step with a 4k converter id be hard pressed to spool up a turbo with a t4 .1.32 housing with only 173 ci, but with an antilag system that thing woudl spool right up to full boost on the line.
the major advantage is being able to run a huge hotside housing and wheel so u dont choke the motor in the high rpm ranges

Re: anti lag system FTW
goto basic settings on megatune,and click on the bottom of the menu were it says basic/advanced user then selecte advanced and u will unlock the launch control and many other features,sorry it took so long ive been dam busy
btw this will open up settings for thingslike traction control nitrous control boost control the antilag etc

I activated MSnS extra in the configurator and then set my cars profile code to MSns_Extra and started megatune... mine looks like this.
this is confusing... Also will running the extra code on my MS scrap it or not? i dont wanna fubar my MS with bad firmware
----------
i found it under the general tab.... for what ever reason my Megatune looks different than urs...

Re: anti lag system FTW
what version of megatune is that, im still using 2.25_p4
u dont need msnextra thats for ms1 cpus, the base ms-2 code has all the features
nm i see u have an older verison
open the configurator and setup a test car with ms-2 code and then do what i posted above to unlock the features

when i load the car with the MSII code megatune gets all stupid and runs slow and shitty...
I've yet to test this on the actual car im just trying to get comfy with this b4 i do it

Re: anti lag system FTW
im sorry i was wrong i thought i had 2.25_p4 i do onfact have P3 i would backup ur vew files and try to reinstall are u running vista by anychance?
http://www.megamanual.com/files/soft...25p3_setup.exe
u could always try megatunix, which is the unix/linux tunning software but its been ported to windows though on my old *** laptop it ran slower then megatune
