COBB ATR Discussion thread

[SallySpeed3]

Just got Accesstuner installed on my computer. Holy Crap it looks so confusing, but anyway. I thought ATR allowed the use of "no lift shifting" and "launch control" to be added to base maps. When I open ATR I can't find anything dealing with those, or in the manual. Any help is appreciated.

Is it safe to use cobb turbo inlet tube and sf sri on stage 1 93 + sf?

yes

Thanks, I set it back to the stock tune anyways, I'll put the map on when I wanna have fun

Keep the most aggresive map for your mods on your car and control the power with your right foot.

Do you have the v105 maps? I think LC and FFS only work with those maps and in ATR they are listed toward the bottom under Limiter Tables. You will need to set your LV Vehicle Speed Limiter to like 13 [means the LC limiter will only kick in under 13 MPH] and Hysteresis to 2 [don't remember what this is for but it is explained on here somewhere]. I have LC running at 2800 but that is just a personal pref.

 

[SallySpeed3]

Yes I have the v105 maps. I'll try doing some more research. All I really want is the flat foot shifting. I've heard launch control can be harmful if you do it too much, and it's not like I'm taking my car to the track every week.

 

[Dano2010]

The limiter tables are right between Ignition Tables and Load Tables. Yeah unless you are at the track with some slicks LC is useless.

unless your running catless that launch control will fill the cats with junk and fuel REAL fast

 

[Dano2010]

interesting point. so when the ignition is being cut by the limiter, fuel is still being injected and pushed out to the cats?? Makes perfect since.

 

[manelscout4life]

um the way cobb set up there launch control fuel also gets cut down so it doesnt just dumped into the cats.

We do not have any direct data on how LC/FFS effects catalytic converters. However, these functions were designed for "track only" applications and catalytic converter damage is a bit of a secondary concern. I will inquire with our tuning team to get a better answer for your concerns.

thanks travis. quick question, what should i gap my step colder plugs?

.028 iirc

Wouldn't any gas that is dumped into the cylinder during this time either still explode when it hit the hot cylinder head, exhaust manifold, turbo, and possibly not even reach the cats?

 

[79535]

I don't think that all of the fuel being dumped in to the cylinder would ignite. I haven't tried LC in this car, but I'm assuming it sounds like all the other LC enabled cars I've heard where it is constantly backfiring (fuel igniting in exhaust).

My car recently had a misfire issue that was triggering cat efficient codes so I'm assuming LC would have an even bigger effect. AP disables this engine code AFAIK so you would never know it was killing your cat.

I have the LC for auto-x starts and it doesn't pop or bang. Just sounds like its hitting a rev limiter. I don't think doing it every once and a while would kill a cat.

 

[79535]

More encouragement for me to try it out I guess

 

[daonly1around]

what do i need to do to access that launch control?

 

[79535]

Load a map in ATR and set it up in there. There are some specific settings you must change that have been mentioned previously in this thread I believe. This is the best I can remember.

One value is a speed limiter for LC (set it to say 10MPH). This prevents LC from activating over that speed.

The other value must be set to 2 if I am correct (not sure what it is or what it does).

Then just set your RPM I believe.

Someone more experienced can come and tell me I'm wrong
