Hey guys, can you tell me some good techniques on launching with an automatic? I dont have a stall converter and my stall rpm only goes up to about 2100-2200 when power braking. I've read some other posts on the net and lots of people say that when launchign with an automatic its better to just leave it in drive from the start instead of starting from low gear and shifting upwards. Can anyone verify for me which technique is better? And when power braking, am i only suppose to step lightly on the gas then floor when my car is already in motion, or am I suppose to floor it straight from beginning then release brakes?

i was reading a post in the auto section about the same thing...from what i read and tested i wouldn't worry about power brakin at all....I put it in 2nd and push 50 % throtle on the start then mash it.....they say that if u leave it in 2nd the car is faster.......feels like it is too me.....redline first (dont shift it will do it its self) then redline 2nd and shift too drive.....oh yeah......all ways keep overdrive off.....

the second gear launch was read in the manual of the eclipse .. in the manual it says its shifts faster ... somehow i doubt that ... ive had my auto now for 3 years and the best possible launch i have had so far is
depress break
lightly hit gas as soon as u hear an engine reaction .. release the break ... depress throttle 3/4 ..at around 4500 press foot all the way down & enjoy!! u know its done right when u feel a good pull after the break is released ... no chirp .press foot all the way down
power breaks work also ... just remember not to hit the stall speed .. than the tranny goes into safe mode ..

I would put it in first, and power break to about 2000 rpms, then just floor it when the light turns green. How come some of you don't floor it off the line? I ran 17.15 with this method. You can even leave it in first, because the computer will automatically shift to second and third. Just keep your foot all the way down and don't bother manually shifting the lever.

My first time at the track, thats all I did was power break and mash the gas at the light. when I do this my engine seems to "bog" down and it takes it to about 3-4K PRMS to straighten itself out and fir normally again. next time I'm going to try the 50-75% throttle method then gun it. I read a post about it and it makes perfect sense. when you gun it it off the bat it kills the timing and shit and the car kind of flouders searching for the best air/fuel/timing scheme resulting in lost HP and lost time. This seems to work better in practice on the street for me so I'll see what it does to my times. OH the best time I could run with the power break method was a 17.9 Thats with the Short RAM intake, GS-T exhaust, and UDP.

power breaking makes a huge amount of heat .. the tcu thinks something is wrong with the trans and puts it into safe mode .. basically locking up way earlier than 3rd gear
