1/4 mile with just jb4

WDBi · 03-26-2011, 02:47 PM

Fastest time was a 12.940 @ 108.97 mph I launched at 2000 rpms with dtc and ds shifting into 2nd and I shifted after that

Any suggestions how I can improve my time?

i think he means that he has a auto and after first gear he shifts his car. I shift just after 6k gave me better times in the 1/8th

XDEEDUBBX · 03-27-2011, 12:34 AM

what map were u running?

slow4.7 · 03-27-2011, 12:39 AM

was this in a 335i sedan from your sig?

WDBi · 03-27-2011, 04:55 PM

It was map 2 jb4 I have a coupe

lightning20 · 03-27-2011, 06:58 PM

so you had traction control on? If so you will post better times with it off

XDEEDUBBX · 03-27-2011, 07:10 PM

have you tried map 5?

WDBi · 03-27-2011, 07:31 PM

map 5 is slower than map 2 because map 2 will be 14.5 set map 5 will just be 12-15 depending on mods but im stock so it would be around 12 especially in hot humid florida

also yeah ive been alittle confused by traction control i just pressed the dtc once not holding it

I know what he meant; launching in 2nd gear on street tires with the auto is the best way to idiot proof the run.

From what I understand, Map 5 will autotune to like 10-11 psi for almost all people. Stick with map 2 for drag strip runs on a JB4.

Agree. Going to run on the april 15th (1/8th mile) and will try different maps to see the diff between each but i know map 2 will yield the best results

WDBi · 03-28-2011, 06:35 AM

I put it into ds let the car shift into 2nd then with the paddles I shifted into 3rd 4th etc
my 60 time was 1.987

Kayani_1 · 05-03-2011, 09:47 PM

Have you tried map1 and how did it compare to your map2. I am stock and running map1 on 93 oct. I was just wondering is it safe to run map 2 or just stick to map 1.

TXe92 · 05-03-2011, 09:51 PM

is that typical with just a tune? What altitude are you at.. stock tires?

I ran 12.7 with jb4 and dci(2nd gear launch) fastest time i have read was 12.6 but i did not see the slip

SaviorXi · 05-05-2011, 12:11 AM

I have an 2008xi coupe and with just cobb accessport and 93 octane map I ran 12.6. I hold the DTC button until the dash warning light comes on then put the auto into sport mode. Hold the brake and floor it to 2500rpms the let it fly.

aandrew335 · 05-05-2011, 12:38 AM

^Does that say 0-60 in 3.9 sec? If so, that amazing and i want your mods haha.

my cobb doesn't log like that its always blank for 0-60 times, here is what I do so tell me if i'm doing something wrong
set the cobb to log 0- 60 times (press ok and get to the screen that says accelerate)
put the car in DS mode, foot on break upto 2000 rpm and launch
but even after hitting 70 mph there is no reading?
