Does the throttle response improve? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

pr086 · 11-21-2012, 07:26 AM

Just picked my car up last night and it seems like when i press the gas pedal it doesn't increase the revs right away. Like theres a little bit of travel in the pedal, then i start getting revs. This combined with the high clutch engagement is making starts kind of difficult snd ive been driving manual for years. It doesn't seem like i have percise enough control of the revs when starting from a stop. Does it stay like this or get better? I know there is a period where the ecu is learning, im at about 70 miles now.

Yes. It wakes up a ton after the first few thousand miles.

Is what im describing normal? Once im going there doesnt seem to be that delay in responce. Just starting from a stop theres a couple milimeters or so of pedal movemet that does nothing

its normal, almost every new car on the market today is exactly like that till the negine breaks in, overhwlemingly fluffy.

Ok nice!

Yeah, in the beginning it caused me a lot of grief when starting off in first gear co-ordinating my two feet. I'm now over 3,000 miles and things are great.

Yeah it annoyed me too that there was a deadspot in the first 3% of throttle pedal travel. One thing that helped was moving the seat bottom one notch forward. I can't exactly explain it, but it seems when you sit closer to the pedals, you don't notice it because you naturally push the pedal deeper.

As long as it goes away thats cool, just glad mine isn't the only one like that

Quick fix for the clutch engagement.

It sounds like throttle by wire to me.

Do you think it might be that you got used to the clutch after driving it so often?

MI FR-S · 11-21-2012, 11:22 AM

At 1300 miles and mine is still slow to respond.
It makes pulling away slower than it should while I wait for the the revs to arrive where I want them.
It also makes rev matching a bit trickier and I have taken to blipping the gas pedal twice. A light one to get the slop out and then the real one to bring the revs up.

Hope it gets better soon!

It's the drive by wire. There were a few things at SEMA that I saw to remedy this.

The throttle response is a bit slow with drive by wire. I guess we'll get used to it. I would say that every new car now has a kind of throttle lag. That's why I still enjoy to drive my quick-responsive and happy to rev high old Honda.
