This thing is horrible on the sx4, too slow and computer decides just how far it really opens.

I know the motor is alot better if it could breath.

Anyone know of a method or aftermarket add on to gain control of the throttle body and make is follow what my foot dictates?

Give her a chance to break in - also tweek it by trying different brands of gasoline (NO, NEVER premium) and synth oil after 10K miles. My car was never ready to romp until I got 15K on her (04 aerio SX 2.3L 155HP) Then she got noisy and now shes gone ... (sob)

OTHERWISE, you bought the worng car! Man, Didint U really notice this during a test drive? I know, I hate those short test drives ... plus you tend to be a bit n~e~r~v~o~u~s:whistling:

Hey guys

I'm a writer, doing a story on the SX4. I spend two weeks with the AWD JLX, and a week with a base model. Both were manual. I noticed that the revs seem to lag, not dropping fast enough when upshifting, and attributed it to drive by wire. Another reviewer thought it had to do with the clutch.
I found this on another forum,(see below quotes) where owners are discussing a dealer flash to quicken throttle response. Have any of you owners tried this yet, and if so, was it effective?
Thanks for any responses you can give me. Nice car, the SX4, enjoy them :)

(from another discussion board)

" Has anyone taken their's in yet for having the Engine Control Unit re-programmed, as per the bulletin that was sent out last month? I would like to know if it makes any changes to the sensitivity of the drive-by-wire throttle system? I am hoping that it will alleviate the tendency for the engine to rev up during upshifts. That trait is about the only complaint I have with the SX4, and may end up complaining to the manufacturer about it.

Makes no difference as far as I can tell. I agree the drive-by-wire response "stinks" but I did know that prior to buying it.

I bought mine knowing it took more concentration to shift smoothly than most cars, but I thought I could get used to it after awhile. The problem is that it's not consistent, so it's hard to get smooth shifts everytime. It's a bit embarrassing if you have riders, because it makes look like a "student driver!" Has anyone with a stick shift SX4 had this ECU re-programming done yet? My dealer hasn't done one yet, so they can't tell me what difference (if any) that it will make in the shifting."

The service bulletin involves reprogramming to correct a logic error that can result in "false" illumination of the check engine light. As far as I know, that is all that it "fixes." My dealer hasn't performed any of these yet, and wasn't able to tell me over the phone if it would help the throttle lag. Please call Suzuki Customer Service and register with them if you are having this problem. Their number is 1-800-934-0934 (USA). I know of only one person who has taken their's in, and unfortunately it was an automatic. He did say there was no difference that he could tell in the operation of the throttle.

hi, i just bought the 1.5 litre version of sx4 (M15A engine) and I experienced the same problem.. if i kick the clutch & release the gas pedal.. the RPM won't drop momentarily..

& it sucks for me because when I try to drive it on a climbing road.. (hilly road) the RPM drop as if the throttle could not open full throttle..:( it closed the throttle as the car climbs..!!:mad:
