So do all LS1 cars have this slow throttle response? [Archive] - NJFBOA - Home of New Jersey's Camaros and Firebirds

This drive by wire throttle lag sucks. Now I think I know why people say the LT1 feels stronger down low, because it responds quicker! But my 2000 SS will break the tires loose a lot easier than my 96 SS did. So is there a cure for this lag other than mashing the pedal to the floor faster? :scratch:

It's all in the tuning....

a kid i met at school tuned his to eliminate it! but i dont know the program he used!

I didn't realize Camaros got TBW.

LS1 fbodies arent drive by wire.

No? I thought they were in 99+....

well they have throttle lag for some reason and there is a way to get rid of it why wouldnt they be drive by wire Little G,s car is

His is a 3.8 though Phil, there were lots of differences between the cars.

nope, only the vettes from 97-02 were drive by wire. the GTOs may be by wire too, im not sure. LS2s are. but i do know camaros and bird LS1s were all cable driven. Vehicles with traction control are a little odd, The ASR option connects the gas pedal to a "motor" which then goes to the throttle blade. when asr is activated, the "motor" turns back and closes the throttle, in turn actually pushing the gas pedal back up.

99+ 3.8s were drive by wire

i guess so, but you would think that they would use the same technology!
i dunno i may be wrong

...but not all 99s were. That was a changeover year.

if you say so.. lol i dont bother with the v6 info hehe

either way tuning could only help the problem!

I thought they all were too, until one of our members (can't remember who off the top of my head) bought a throttle body after confirming that it was a 99 like his car, and one was cable, and one wire.

yes, tuning should take care of it easily. I havent driven my SS in almost a year and a half so i cant remember what the throttle response was like. I'll be using HP tuners so if i notice any lag on mine, ill look into dealing with it.

may be some torque management and other fun stuff put in the a4 cars.......talk to foff

as far as I know, none of the LS1 F bodies were TBW. all were cable operated.

Squirrel

maybe its somehow connected to piston slap??

PSBW? Yeah, it's a cable(which is actually wire) and the car has traction control. It's a sloppy cable for sure.

Tighten up the cable, get a tune and/or modify the T/B to put in a n idle adjusting screw. If you just bump the blade open a little bit it makes a big difference. Mine was always pretty instantaneous, do you have an A4? Could be torque managment or TCS

Mike

12-20-2006, 07:58 PM

if the previous owner installed a throttlebody he may have bought the 98-99 version which has a different cam and would make the cable loose, i put the 2000+ tb on my 99 and the blade stayed open...

if the tb is the culprit i have a 2000-2002 piece that you can have if you have a 98-99 one

12-20-2006, 08:02 PM

FWIW, to identify a tb(if not modded, just swapped) the throttle spring color on a 2000-2002 TB is blue, 98-99 is...i dunno...yellow i think

i noticed a huge improvement in throttle response when i had my TB ported... its cheap and the improvements are amazing

big difference in response on my Z and now on my vette

most of what hes feeling is probably torque managment and asr.... have bill take off the torque management huge difference

3:73's and a tune by Bill will make it feel like a completely different car something he does to the shifting so the car downshifts when it is supposed to instead of lagging which is probably what your refering too. He explained to to me that normally the computer won't downshift to give you that power until you mash the petal down to 75% throtle or something but he chnages it so anything over 50% shoves it down into the powerband and you take off. Not to mention if ya get rid of torque mangement your going to be chirping 2nd pretty easy so give him a call !!!

thats a good point... what kind of gears does that bad boy have?

my throttle response is excellent, but i have a little done. on my car it was never really that bad though.

JL8Jeff

Oh boy, I just went through inspection today so I'm good for 2 years. Then we ended up getting a bonus at work which I had no idea about! :mrgreen: So now I have money to pay off the credit cards and enough left for some mods! And if I sell the 4Runner shortly I'll have even more! This could be a dangerous situation...

I would say mild tight converter & LS6 intake & maybe some suspension parts for starters.
