Thanks!

you need to uninstall it.

Hooked up my cobb, went inside while it flashed to stage 2+, came back, car was upside down on its roof. Is that normal? Do i have the right map?

Depends on your ECU. i had no issues with I8AOS, but it was a problem with older ROMs.

ha, i knew it.

Nice hear you are launching at lower RPMs now

I am confused at what you are saying... Isn't brake boosting starting from a complete stop not a roll? such as M2 hold brake, rev to 2.5k - 3.5k.

rader1 · 01-21-2012, 07:59 PM

Brake boosting is when you are rolling and press the brakes and press the gas harder in order to maintain a set speed in order to load up the turbo. Not necessary on these cars IMO

Jeef · 01-21-2012, 08:06 PM

I don't think its necessary for our cars either on rolls

Lulz_M3 · 01-22-2012, 08:55 AM

Brake boosting on any turbo platform isn't *necessary* but it does give an advantage. Would you rather be at 8+ psi of boost when you start your race or 0? Sure it may only take 1 second to achieve target boost but that could be the difference between someone jumping a hood out in front of you.

Assuming you're over 3KRPM it will build boost nearly instantly. Besides, can we brake boost these cars? I know a lot of ETC cars ovvveride throttle input when it sees you press the brakes. IDK if the MSD80 does this or not.

Jeef · 01-22-2012, 11:09 AM

^ yes 3k rpm is where you should be at starting from a 40 - 60 mph roll.. well if your in the right gear, so brake boosting doesn't really give an advantage, IMO. Also is launching the car by holding the brake in M1 or M2 and revving to 3.5k bad for the car at a complete stop?

Yes, launching the car from a stop is bad for it. However, there are people that do it dozens(or hundreds) of times and have seen no ill effects. I heard of a few xi drivetrain breakages, but the normal RWD layout seems VERY sturdy. I wouldn't risk it because if you're very unluck and something does break it will be very expensive to fix.
Of coarse, if you have crappy tires the car will just roast 'em lol

I'm 6mt so I'm not sure about the auto's reaction but give it a shot. Trust me, it makes a difference.

vadim83 · 01-22-2012, 02:30 PM

is there any dyno comparos with proceed v5? I'm assuming stage2+ aggressive map..

Tune+meth setup should be similar to a stage 2+ FBO car. There is a video of clap/laloosh/asshat(or whatever screen name he has now) running stage 2+ against jeff@topgearsolutions and his V5+meth car. Its pretty close but the cobb car pulls just a little each time. Keep in mind it's 135 vs 335.

Jeef · 01-22-2012, 03:25 PM

Any updates from cobb on when race fuel maps or meth maps will be out?

Can you post that vid?

themyst · 01-23-2012, 09:49 AM

There's also a video floating around out there with me and clap at the strip running each other with the same race map.
