Does the throttle response improve?
 

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?

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. ;)

Yes. After I made the above post I considered that. In the beginning I thought the light spring tension on the gas pedal made it more difficult than usual to co-ordinate my launches but your suggetion holds a lot of merit.

The combo of DBW, Denso DBW voltage settings, soft/high clutch engagement, and non mechanical clutch all lead to that "vague" feeling you describe.. Throttle controllers may help a bit but id say a custom tune + clutch pedal adjustment would minimize most of the wierdness.

By nature, despite the response, there is a very small amount of movement before the controller actually moves the throttle plate at idle.
I've observed this during logging with the EcuTek software.

Wait, we don't have an actual clutch in this car? What do you mean?

I think he meant hydraulic instead of cable.

Probably non-mechanical throttle linkage (ie. Throttle by wire).

Thanks for clarifying that.. Hope the clutch adjustment helps..

Am I the only one who finds the throttle way too sensitive for normal driving? From a standstill I sometimes spin the wheels inadvertently, especially when taking a turn.

So todays new cars are stepping backwards? Awesome.

Adding the Perrin Crank Pulley helped that out quite a bit for me (though I may have also gotten used to it a bit too). I noticed an immediate difference after I put it on, the engine feeling like it can rev up quicker. I am sure any of the crank pulley's out there would likely give the same thing.

I don't think it's a matter of the throttle being too sensitive but I do contribute a lot of the problem to several things. One, the throttle spring is so light that it's hard to tell if you're pressing on the gas pedal or not . Two, the car is so quiet, which I prefer. Three, my hearing is bad enough that it adds to the problem of not knowing whether I've pressed on the gas pedal or not.

If you're any thing like me you've driven a lot of manual transmissions in your life. What I've had to intentionally do these last several weeks is get out of my comfortable old habits and go back to basics in driving and work at it instead of doing it "marginally o.k. I've noticed a marked improvement. In fact I just got back from my evening drive and since I've made a concentrated effort I'm much happier with my performance. I'm thinking I just allowed myself to get a little too relaxed and sloppy.

I noticed these things you pointed out as well. And sometimes, I do get a little relaxed and sloppy. However, when focused/paying more attention, and in lighter shoes (back and forth to work I drive in military boots..x.x), after the pulley was installed, I did notice an improved response from the pedal after adding a pulley. Not just a feel thing, but watching the tach as well. I've taken it off and put it back on a couple times now with the same results, removing some of the sluggishness in the response. Maybe it is just me or maybe the pulley actually does some good. I tend to lean toward the later because a few of my friends riding around with me have also mentioned that they noticed a difference.

That clutch take-up point is extremely irritating at times especially in a quick response situation where your muscle memory remembers a particular clutch takeup point and nothing happens in this till the last few mm.

I am giving myself time to adjust but someday I might just go ahead and change the take-up point.
@akyp: Do you think the reason you find the throttle too sensitive because you end up giving too much revs due to the odd clutch take-up point.

You know about the don't go over 4000 RPM till you get past 1000 miles right? Just in case you missed it in the manual.

The clutch take up point surely didn't help. Now that I think about it, the throttle seems okay when the clutch is fully up. I need to find some time to adjust the clutch pedal.

Yes, thanks. Been lurking the forums long enough to know haha. May have hit 4200, 4300, a few times. But ive been being good

I'm one of the few people that think the engine actually makes good power and torque for a stock 2ltr engine but i am still surprised you find it too sensitive. What were you driving before the 86?

I think it has more to do with the calibration of the DBW than actual power and torque. My previous cars are Audi S3 and RenaultSport Clio 172, both had a very linear throttle pedal response.

Actually now i think about it i have thought to myself at times the throttle seems to come on quick then the sensitivity reduces after about half throttle. I put this down to the relatively large throttle for size of engine.

On an off topic note, how did the clio compare to the 86? :offtopic:

This would be an interesting comparison. You'd think they are worlds apart but they are not. Both are very light cars at their own times. Both have a 2.0L NA engine, basic but functional interior, and relatively skinny tires (the Clio has 195s). So both are very nimble and fun around corners. Of course the Clio won't drift like the 86, but it being a Renault means it's one of the best handling FF cars out there. In a straight line, I think the Clio wins but the 86 is still during run-in. Steering: 86 wins with its precision, feedback and quick ratio, but the Clio is just slightly behind. Gearbox: 86 wins hands down.

@Turdinator: Very good point. I find the flat torque curve sometimes annoying when you are really giving it the beans and the torque doesn't come on proportional to the revs.

+1 what I've been saying..

So agreed. Day 3 on this car and i feel like im a driving noob. And my last 3 cars have been manuals over the last 6 years daily driver, so it aint me. This clutch is worse than my stage 4 6puck in my old booste tC. Cant feel the engagement
