Help! Underpowered more than stock? 0-100 = 10+sec - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

pakunodafie · 04-14-2019, 04:52 AM

Hey guys I feel my 86 is a little bit underpowered compare to the other 86s stock.

I test drove others 86 stocks and I felt there is something wrong on my car.

Car is Automatic / fully stock except Invidia N1 exhaust.
• Car is sputtering / hesitating at 2500 rpm
• 0 - 100 is around 10+ seconds
• High gas mileage 14.6L / 100KM
• Idle drop - 1000 rpm then drops at 700. Never get stalled.
• Car model is 2014
• Warranty until 2019 August

Video attached for acceleration!
Please help!

What wheel/tire are you on? The XXRS could be a huge contributor here. That is pretty slow feeling. What grade of gas do you fill the car with? Do you get the gas from the same place?

I'd also recommend disconnecting the battery for an hour, plugging it back in, and going for a drive. I'm theorizing that your car has learned around some knock and pulled timing because of it.

If you know anyone with an open flash tablet, try flashing your car with a map that's close to stock to see if it helps.

Hello, I am using 215/45/R17 Stock tires. Im using RON 98. since day 1. I get the gas on different places.

Will try to remap it or ask for a tune. Maybe it helps.
Thanks

Are you still using those XXR wheels though? I replied initially after having just woken up, you definitely can't just get a re-tune from someone else's openflash tablet. So I'd look into getting one if performance is something you're after. It's only 400 bucks used, and will make a huge difference in your day to day driving.

Car sounds like it has a misfire

It's out of my budget as of this moment. I just want the normal acceleration. BTW XXR wheels are in another car.

I am now using stock wheels/tires.

Not sure if it has but I do not have CEL on.

StraightOuttaCanadaEh · 04-14-2019, 01:04 PM

Misfire doesn't always come with a CEL from my experience.

If I have misfire what is the culprit?

If the cars still under warranty and having issues, adding an aftermarket tune is a bad idea. Easy for a dealer to go oh you messed with quirk ecu... have a nice day

That sputter/misfire starting at 2400 RPM is real. Don't mess with it. Take it in and make sure the issue is acknowledged on paper.

For me it was a coil pack. Different car though. Could be a spark plug as well

I second what @Ultramaroon suggests, take it into the dealer.
