poor throttle response
 

hi could someone help me step by step.. dose someone experience same what I do ?

I just installed CAI and I drive it for half an hour then I disconnect the nagtive battry tinrmal for 20min and then put it on agine I allowed the ECU to reset so the rexults now a Poor acceleration\slow throttle response.. please could someone help me out:iono:

throttle will always be a bit sluggish after ECU reset or flash. Give it a gas tank and it should settle. ECU needs to get adjusted to the stepper motor in the throttle plate.

Could try Jeff Perrin's suggestion of turning car on without starting the engine, fully press and release gas pedal 20 times, turn car off, turn on without starting again, press and release 20 times again, then start engine. No more ECU reset dead pedal.

which CAI did you install. from what i understand all CAI will decrease throttle response because they increase top end power only.

Like others said, it has nothing to do with the CAI, it's the ECU reset which is causing the throttle lag.

does this work? I'm going to try this after work today =) was just rummaging around.

A CAI may affect the low end power/torque and feel a little more sluggish when the car is trying to move, but as others have said the throttle response is due to resetting the ECU. The computer needs to re-learn.

Yes, but you only need to do it 5 times. I've posted about this before and I do it every time I re-flash.

It works. Jeff Perrin told me about that a few months ago and I do it every time I flash now.

Thanks, I tried it after work yesterday.
- Car set to ON - step on the peddle 20 times or so (full on and full off)
- Turned the car off - stepped on the peddle 20 times or so (full on and full off)
- Turned the car back to on - repeated step 1
- Started the car completely

There was some improvements. Just wondering is there a guide for this?

You don't actually need to do the pedal thing (step 2 above). Just turn off the car and turn it back on again before repeating step 1.

I've never seen this published anywhere else but from Pete and a few others who have variations on the theme.

Ahh, thanks for clearing that up -- i'll do that again this afternoon

Reset ECU, turn car to accessory. Slowly depress the accelerator 5 times fully to the floor. Turn on car. Its just so the ECU can register 100% pedal movement. That is also why you get dead pedal for a while if you don't. Doing it with the car off is pointless as the ECU isn't powered up.

This works, 20 times is a waste of your energy!

Yizusss!!!! Thanks to this post and Kodename47.
I was going crazy with this lag!... Thanks! :bow:
Im happy and relax now.
I thought my car was damaged!
