Anybody put on some miles with anti lag ON and a big turbo setup? Too aggressive?

imo the anti lag needs to have some mechanical modifications to make it work properly (a throttle stop). the iacv isn't going to cut it.

I've tried it and it does work. It's a soft anti lag. Looking at the ROM, there are different values in the tables for different TPS values. So I think you are supposed to adjust the throttle plate screw open more for the antilag to hit harder.

To the guy who posted above, either way this isn't something that you want to put a lot of miles on, if you care about your engine and turbo lasting a long time. I was just going to use it for drag racing, 20 seconds at a time.

Odds are there is a map that determines iacv duty per ect/rpm. I'm sure this is involved with the mode byte as iac duty nears 100% at idle with al set.

There are enough undefined items in this rom to make a person cringe

I lift off the throttle and it pops and bangs a bit and makes a few psi of boost.

i guess you've never had launch control, eh?

as anti-lag systems go, this one, on a stock car w/o mechanical mods, is useless: there is just no way to get the requisite amount of air past a closed throttle to give the hot side any puff.

I've been using the tinywrex LC since he released the patch. I actually couldn't get the LC on this ROM to work. I think possibly because of differences in the neutral or clutch switch inputs, but I didn't check.

Anyway this is while driving, lift off the throttle and it antilags a bit a light popping and banging and rpms hang at about 2000 3000 rpm at about 1-2 psi. I think looking at the way the idle is set up, you need to adjust the throttle plate so it is open more to get more of the antilag effect.

This isn't a hard flame shooting full boost antilag like you hear on open class rally car and drag cars, it's softer, but it does do something.

I gave up on this rom and went back to maf, for a few reasons. I couldn't get the antilag to be switchable with my 02 usdm ecu, I didn't like driving with a cel all the time, and really I was happy with how my car drove with maf. If I can get a V7 or V8 ECU, I would try it again.

Oh what the future holds for this rom

So many undefined tables/compensations/fixes......

Oh yeah? Who's doing the work on the definitions and new tables? It's beyond my ability for sure.

I'll try tomorrow with BOV plate and throttle stop. Maybe it will do a cool link/autronic style injector cut idle.

i have an OT question for u guys......in my 02 wrx i installed a aem 3.5 bar MAP sensor....and i rescaled it so that it reads 5 psi low since the 16 bit ecu wont allow for inputs above 24.75.....

i just put the car back togehter and started tuning it again.....well im putting down almost 100whp less in airboy. Same boost, same afr, same timing....100whp less. the car was sitting for 8-10 months with gas in it ~1/4 tank. i put 6 gallons of 95 octane in and 1 gallon of meth to try and clean it out. is it possible that the old gas is that bad and is causing the power loss? or is my motor done?

i havent gotten around to a comp test or a leak test.....just kinda confused and pissed right now.

did you change any of your WGDC settings? or adjust your mbc? Could be your map scaling off up top lying to you.

im just running a perrin ebcs.....yes i changed the wgdc.

"20 psi" which is 25.25 psi from peak to redline. 14* up to 20* of timing. 11.3-11.5 AFR.

thats giving me 310 whp in airboy. copy/paste this log into airboy and graph the maf g/s.....it goes nuts.

use 06 sti since i have an 06 sti 6 speed and total weight of 3000 lbs.

Well your moving about as much air as I do @ around 360-380whp on airboys...

By chance did you check tire pressure.....? I mean it was sitting for a long time.

yup....aired them up to 40psi all around.

how are u determining my airflow? how are u getting 360-380whp from my half maf'd 160 g/s?

the way the maf jumps seems to tell me there is a leak somewhere....

for reference here is the last log i did in february. pre blow through, but with the fmic and the car was 3280 lbs total with me. its 3000 lbs with me now.

I could care less about your load value or g/s- they are BS numbers.

Your MAF V tells me on a 3" inlet/blow through (which I run) and see 4.44-4.48v on mine that your HP number is close...

Throw in your old weight with your new log... Alot of things could effect this - but imho improperly scaled map sensor could cause this as well, basically tricking you...
