Sloppy throttle pedal
 

There is a half inch dead space in my Accelerator pedal.. is this normal?
https://youtu.be/sEdpUSX0--A

I've stalled pulling it out of a parking lot many times. Do frs's just have that or my car is an unlucky one. Also, when it's going like 5-8kms an hour and I put my foot on the gas, it takes a second or 2 before the car starts accelerating.

Any help would be greatly appreciated

It is a drive by wire not a mechanical linked system. Yes there is a bit of a dead zone but you get used to it.


You truly are dead set on finding something wrong aren't you!!!!

You could disconnect your battery and let the car relearn the throttle. Is the car stock?

the million dollar question..place your bets fellas

Lol! Sorry about my paranoia! The throttle does seem sloppy though.

If you don't have a tune odds are it's acting a bit wacky from the intake and reverting back to the OE intake will feel better.

I've read that a lot of people had sub par performance from just strapping an intake on there and not tuning it, so i'm betting this.

Agreed with above. Go back to stock intake. That doesn't look normal. If I was blipping my throttle like that you would hear my N1 exhaust rumbling. This car has a very sharp throttle response.

Agreed, even though the car is drive by wire, throttle response is pretty spot on 99% of the time.

Pretty sure he is just talking about that little bit of travel when you first push it not that he is pushing it and things are not right.

Watched the video again, pretty sure mine totally stock acts the same way from day 1 to now. Throttle just takes a bit more action to get a response vs. a real mechanical throttle.

Yep. It was the very first thing I noticed when I test drove the car. Wouldn't be surprised to find it was designed in since so little pressure is required. Makes sure you don't accidently rev the crap out of the car just by touching it.

That's more than likely your problem. The intake when swapped can cause some bogginess without a tune and have some dead space. Try disconnecting the battery to reset the ECU, it should work, but if not then you might want to go back to the stock intake.

..it is a simple machine, why be paranoid...http://www.truedelta.com/Scion-FR-S/reliability-1096

...like most Subies and Toyotas there aren't any major problems..

Like @Tcoat mentioned, my car had a dead spot right off of idle, particularly when the car was moving slowly and then throttle was reapplied. This was most noticeable when coasting through low-speed corners, the revs would drop to under 2,000 rpms, you add throttle on corner exit, and then the engine seemed to fall into a hole before it would respond with an abrupt hit. Initially I thought it was the torque dip, but it wasn't that the car was down on power at the time, it was that the throttle was depressed and the car was absolutely dead...until it wasn't. Throttle response was sharp at all other rpms and the car ran perfectly at speed. My car did this stock and with a Cosworth drop-in filter.

The throttle realy should not have dead spot or be laggy.

unless theirs somthing wrong or

you just reset or reflashed ecu
the maf scaling is off due aftermarket intake or you have air leak
you have exhaust leak upsetting 02sensor readings
you running rearly crap fuel and its getting a lot of knock

you should be able to go heavy of full throttle at any rpm and its should not bog, it may not pull very well at low rpm but should not die

What happened that made it work fine ?

My experience with FR-S that had intake / exhaust done was that the low revs felt more vague and sloppy, at least at clutch engagement. Couldn't tell by feel or sound where the lower revs were (this was a muffler delete, so all I could hear was mostly drone).

Your symptom sounds like the ecu is still learning, have you pulled the battery recently? Also to add what others are saying, your car won't work right with that intake without a tune.

Of course they'll find something. I've even read lately that all the '12-'16 models were designed in a rush ... What else we'll hear ...

I assume it was the EcuTek Pro ECU and Delicious Tuning ECU reflash, although an ACE 4-2-1 Type-A 350 equal length header, Motiv catted front pipe, and Blitz Nür Spec stainless steel exhaust were installed at the same time.

Here is an update to this thread and sorry for bringing it back up.

Today I got in the car, warmed it up and now the dead space has pretty much all vanished. There is the tinyest (and I mean like 0.3 inch) play still in the throttle but the response now is pretty damn good. I did drive 300kms the day before so maybe it did need to relearn everything as I did install a subwoofer. First gear does still feel someone sloppy though from 1 k to 3 k rpm but it has gotten a lot better and I think a tune would probably take care of that considering I have injen intake. I wonder if open flash tab from vishnu would cure that or would I have to get it ecutek tuned

Yes sir, I have that on my vehicle as well. DBW has it's ups and downs. I take that as a safety precaution. I'd worry if it were my brake though. Mine has 1/10th of that play but not my accelerator.

Intake is more than likely the cause, too much air for the ECU. I have OFT, and the only thing you have to do for a new intake is scale the MAF, which can be done by either datalogging and perfecting it yourself, or by using a pre made chart available on the forums.
