blackturboblack Posted May 24, 2011 Share Posted May 24, 2011 Greetings all. I just don't get this Cobb AP. I'm at stg 3 and the Launch and flat-foot shifting settings are available. Here's my dilema: Shouldn't the launch be set as low (RPMs) as possible? I'm running a 20G billet screw and it doesn't spool until 3.5k or so. Doesn't launch mean most of the power is going to the rear wheels? So, I'd want maximum propulsion from the hole until the screw kicks in. No? Also, the FFS, shouldn't that be in the power band? Say, 4k or so? So I can run the gears without doubling or lifting my foot? Or do I misunderstand what flat foot shifting is? And finally, once I make the changes in the AP, how do I know they've gone to the car? The little gears don't go around or a progress bar show like when I load a new map. How can I tell I've actually changed the settings? Any help or experience would be gratefully appreciated. Thanks. Link to comment Share on other sites More sharing options...
underground000 Posted May 24, 2011 Share Posted May 24, 2011 You can set the launching RPMs. Power will be going to all 4 wheels because your car is awd. The higher the better launching rpms:) but horrible on your transmission Doesnt the 20g hold boost past redline? You can FFS at redline, this would be better then at 4k In the AP, under tuning (or something) this is where you turn those on You will also need their maps w/ this enabled 5eat downshift rev match:) Powder coated wheels: completed:) Link to comment Share on other sites More sharing options...
underground000 Posted May 24, 2011 Share Posted May 24, 2011 Where did you find the maps for FFS and LC for the 2008? They claim they're available here: http://accessecu.com/accessport/subaru/lgt/LGT-Maps-08-09-Stock-Intake.html, but I can't find them. cobbtuning maps. its updated http://accessecu.com/accessport/subaru/lgt/LGT-Map-Grid.html 5eat downshift rev match:) Powder coated wheels: completed:) Link to comment Share on other sites More sharing options...
RJS5689 Posted May 24, 2011 Share Posted May 24, 2011 cobbtuning maps. its updated http://accessecu.com/accessport/subaru/lgt/LGT-Map-Grid.html I was just reading up on how to do it. It's tempting, but I think I may refrain. I don't want to beat the transmission, drivetrain and other components too much. Link to comment Share on other sites More sharing options...
Max Capacity Posted May 24, 2011 Share Posted May 24, 2011 Before you use launch control you better do some reading and understand what it does. You'll want a good clutch, and set the rpm around 6400rpm or more. Every car is different. I'm sure you can find some videos on you tube. During full throttle shifthing the timing is cut so the engine doesn't rev to high and the turbo stays in boost. As I understand it, during launch control, while you have the clutch in, throttle wiide open, the timing is retarded so the unburned fuel is lite-off in the turbo, causing it to spool and build boost, you can also set launch boost if you have a gear depended set up. When its done right the car leaves without much tire spin. Watch some of the import drag racing videos. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs.

nyrm98 Posted May 24, 2011 Share Posted May 24, 2011 How would you add launch control if you have a tuned map from Infamous? Any ideas? Link to comment Share on other sites More sharing options...

blackturboblack Posted May 25, 2011 Author Share Posted May 25, 2011 Thank you all. I guess I'll wait until I get a better clutch before I mess with this. And my target boost of 20 falls off at or before redline. Link to comment Share on other sites More sharing options...
