How do I launch My Auto GSX??

[2gEclipse4G]

I have a 97 Auto GSX, when I hold the brake and hit the gas it wont go past 2000 RPM is there another way to launch it?

Since your auto you want to do is called power braking.

Put it in 1st, left foot holds the brake.

Now with your right foot give it enough gas so the car pulls forward a little.

Then when it is time to launch release your left foot and hammer the gas with your right foot.

Just don't do it all the time. Your brakes and drivetrain will not like it. But at the track it is your best bet if you don't have an upgraded AUTO trans. You might want to start looking into that now though if your 2000rpm is hindering you. Try to keep it at about 2000rpm when you release it to the floor.

i have a 92 gsx auto. with 14b. i can stall the converter at 3500 rpm. stock converter. a 2g stall is aound the same rpm. i'm luanching at 75% throttle and 15psi. i had the same problem(not going above 2000) till i remachined the wastgate pocket in my turbo. now the wastegate seals agian and my motor spools quicker and stalls much higher.

I'm bringing an old thread back to life... But how the hell did you do that? I mean how did you get it to stall at 3500?

I have a homade auto shift box, and can get all four wheels to spin from a stop in 1st gear. This mod is wonderful and cheaper than buying the shift box from roadsurge..

I know if you break boost for too long the ecu retards timing.

i've had both a 1g and 2g auto awd, and both would pull 3-3200rpm on stock converter

My 95 auto would only hold up to ~3k rpm, not 3500.

Don't do the power braking for more than a few seconds. Forget about reaction times at the strip. Yes the announcer will laugh at you for sitting there but in the end your tranny will thank you for it.

I also put it in neutral first and rev it real quick while i push as hard as I can on the brakes to try and build as much brake vacuum as possible. Always seemed to work for me!

Really I can get about 2500 rpm 2800 rpm, but I reallly havn't treid much lately..I do have to get ready for the track though, so I better practice..Maybe after my 1st time at the track, I will swap in 5spd ecu so I can brake boost as long as I want..It would be nice to get above 3k without a keydriver chip for launch..

I am actually in the middle of 5spd swap, so I was definitely doing some farewell launches to my auto tranny
I do have 5spd ecu file coded to my ecu
I sit on it at 2k for a second, then, I bring the rpms up slowly to 3k building some boost, then i put the pedal all the way down and watch the boost until it hits 20psi and let it rip!
I did have to hold the brakes pretty hard
It would launch like a rocket
I had an upgraded tranny cooler as well.

I was able to get 3k bone stock, but the launches weren't all that great at 8-10psi
Same thing with the 96gsx i used to have- 3k bone stock

See you had the 5spd ecu though..I'm not in need of a tranny cooler, Ill tell you why..I have a tranny mod that allows me to shift manually. I have It setup right now for real quick shifts. Which means lower tranny temps..I'm also on E3 turbo, so it spools a little slower..My brakes are ceramic, so they will be sufficiant enough to hold me..You got 20 psi at 3k, awsome..

When i first got the car, it was bone stock and still had the auto coding. I would get 3k but it wouldn't launch nearly as hard at 10psi.
I was using a manumatic mod as well which worked great for me, too!
I upgraded the tranny cooler for piece of mind, maybe could have gotten by without it

You really should get an aftermarket cooler if you power brake to launch your car, that builds alot of heat. Your tranny mod for manually shift doesn't really help keep temps. down it just helps with wear in the transmission and better 1/4 times.

Your close my friend..EagleTalonTim will back up my next statement..The way I have the mod set up is for quick hard shifts. As opposed to longer soft shifting. When the auto tranny shifts smothley, there is more heat build up because it has to work harder by keeping the oil pressurized.. When the auto tranny uses harder qucker shifts, the tranny temps are lower because it doesnt have to keep X constant pressure.. That's the easiest I can explain that, I hope this helps your understanding with auto trannys..

I SHOULD get an external tranny cooler. Maybe that will be an upgrade for 2010, I'll put it on the list.
