2015 brz blue series engine chirp
 

So I'm still in the break in period for my blue series and I've read about the chirp that emits from the engine. I'm under 700 miles right now and the chirp is insanely loud at idle. Should I bring this thing in for them to fix it or is it something I should just take with a grain of salt? Thanks for the help!

It's not fixable. The chip comes from using gas with ethanol in it. Use ethanol free gas (search internet to find them) and the issue goes away. The dealer will replace your fuel pump but the chirp immediately comes back so there's no point in letting a dealer touch your car and more than likely screw something else up in the process like some people that have taken their cars to the dealers.

It can't be based on ethanol fuel only because I got the chirp after a refuel and we don't have ethanol fuel in South Africa. However it seems to have gone away after 3/4 of the tank is used up

There is only one place in my area( San Jose, California) that sells ethanol free gas and it's 100 octane which runs almost twice as much as normal 91 gas prices. Guess I'll deal with the "cricket" noise if that's the case. Kind of lame considering the car is new and sounds like an old civic with 300k on the motor....

Read this entire thread.

tl:dr; add some ashless two-stroke lubricating oil before you fill up at the gas station and it should get quieter. disclaimer: read the thread, and make your own decision.

I asked this in a other thread, is this just an annoyance or has there been reported failures or issues arising from it?

Try running e85, and tell me how it sounds.. :bonk:

There is currently no fix for this. Other people tried the ashless whatever and Upper Cylinder lube. Some state it worked for them, some state it didn't.

I have my original fuel pump in my 2013 FRS. I occasionally get chirps but they never last. I live in California, so I get the same fuel as you do. What I've concluded from my own observation is that Ethanol doesn't cause it, or else people with E85 would be chirping all day everyday.

For my car, when I get lower than half tank, the chirps come. However, I fill up at Costco and never at other gas stations.

No failures.

I dealt with the same thing whether I was running 91 or E85. Adding 2-stroke oil (specifically TCW3) helped a lot. Crickets are now either much quieter, don't last as long, or aren't there as often.

It's very cheap, and I'm satisfied with how it is now. As background, I work at a Toyota dealership and the old high pressure fuel pump number was superseded sometime late last year (Nov-Dec 2013). People have gotten it replaced with the updated unit, only for it to come back within 1,000 miles. You'll find some people even had it replaced 2-3 times, it always comes back.

There are a few reports of cars with higher mileage (~20k+) where the crickets just disappeared. I doubt Toyota/Subaru is working on any new fixes.

wellcome to the 86 ;)

Has anyone tried swapping it or with a sti fuel pump?

I don't think STi makes HPFP. AFAIK, there is no aftermarket HPFP.

The ethanol free gas is a myth, it may work for some, but I've used nothing but ethanol free gas from day 1 and I have chirping.

I think it has something to do with the additives package that they add to gas. Here in North Carolina, virtually all of the gas that is sold regardless of brand comes from the Colonial Pipeline. Yet many folks have said that certain gas stations/brands give them the crickets while others don't. Since it is the exact same gas, the only difference would be in the additives that each brand uses. I guess it is also possible that the age of the gas you buy could have an effect since it is known that ethanol will readily absorb water.

Lies spread like a plague man.....

It has nothing to do with Ethanol content. It has only to do with the pump internal design. Nothing is breaking down, nothing wrong.

To try and stop the stupid myth, I've run ethanol free gas to E85 and the chirp is the same on all fuel types.

My advice is turn up the radio. After 2+ years of chirps I've pretty much tuned it out.

I love your signature!!

Seriously, all these people posting solutions about how to fix the chirp, and how NOT to fix the chirp... You're going to be getting a bunch of mixed responses. To my knowledge there is no fix. It's luck of the draw, or the problem to this isn't what we think it is.

Someone mentioned earlier that using ethanol-free fuel will eliminate the chirps, but how does that explain my chirp-less engine (knock on wood) that uses fuel which may contain up to 10% ethanol?

Sad that there isn't a concrete method on how to fix this issue. Even more sad that the 2015 Series.Blue still carries this issue.

I love you :wub::drool:

why does everyone and their mother get their panties in a wad about chirping.

Order of most horrible things, according to 86 owners(about 90% anyway):
1. Crickets/Chirping
2. car slow
3. Genocide

It is not an issue. It's already been explained. It's just a sound. DI engines typically sound weird. This is not the exception.

So I shouldn't worry about it then? Hearing that some have been driving with it for over 2 years seems like I should be okay. Just wasn't sure since everyone on the forums were complaining about it. Thanks for the insight

Well, just based on experience. Everyone has been running with this "cricket" sound for 2 years plus. I know some owners on the 70k miles range. No issues. It is really really rare for a mechanical pump to fail and thus far it hasn't failed. I've never worried about it failing and no one honestly should be concerned about it. If it were an issue where they will fail it would be already a known issue and pattern of failures.

How is it not an issue? Just because it is a sound it isn't considered an issue?

Then why do some cars have it, and some cars don't? Just because it doesn't have a performance, or actual impact on the car, it can affect the driver's experience - which is a fundamental component of the 86. I consider it an issue as do many others.

Call it what you want but an "issue" is something that is going bad/breaking/needs fix before it fails. The HPFP is none of that.

This is a summary of the findings.

So the crickets have finally arrived and all I can say is really!!! Car has 1,100mi on the clock now and you can only hear this at a stop with the windows down and the radio off. So basically I will hardly ever hear it and can't believe so much hype over basically nothing. We are so spoiled/demanding as a society in whole it's kinda amazing...

replace the fuel pump with an aftermarket one, problem solved.

There is no "aftermarket pump" for it.

I'm convinced there are production tolerances that explain why some do it and some don't. Mine had it. You could hear it with the windows up. Pump was replaced a few thousand miles ago and now, once in a while, you can just hear something with the windows down. It explains why replacements took care of it for some but not all.

If this car cost more... and had an extra 200 lbs of insulation, you probably wouldn't notice it. But it is what it is, so you'll hear it. There's nothing wrong if it chirps.

That seems very likely.

My theory is fuel additives. It seems like I get them after running 1/4 tank of gas from some stations (then have to deal with it until the next fillup) then after using 1/4 tank of a fillup from another station it goes away. I hope to test this theory on a 3,500 mile road trip in September.

It's not detrimental according to Toyobaru if I'm not mistaken. It hasn't done anything with my car for 2 years besides it being inconvenient once in a while. If that was such a big issue, I'm sure you would have easily found the big thread about it with a simple search, and, as such, would have turned you, or other folks interested in the car, off about the cars and looked the other way if it would be such pain in the ass. You took a gamble and received crickets with your car. Congrats.

The only time I've ever heard it in my 2013 was when my Shell station was out of 91 ethanol free, and I had to buy E10 at another station. It quit again when I was able to fill up with ethanol free again and has never chirped since.

oh really?

Because I have one.

Actually there are many many many. pumps

Some require a little modification to the housing, but that takes all of 2 minutes.

with as many complaints about the chip issue i hope these people never buy a BMW M car. the valve chatter would drive them to murder

crickets smickets

I wonder if the resale value of my car is higher because of no chirping?

Of course, on these forums a bunch of noobs would chime in with
"I can find a chirp-less FRS at my dealer for less"
or
"My buddy is selling a cricket-less frs for way less"
or
"this site(insert link to someone selling exact same thing as me) is selling a chirp-less frs for less than you"


although, in all honesty, we should have a "Chirp/Cricket section" under "technical issues"

Like this?

Shell Gas - 93 Octane here in the DC region - gives me the worst crickets, even after my fuel pump replacement in February. Know a few FR-S drivers around here who avoid Shell for that very reason. Exxon is intermittent. Sunonoco and Sheetz gas never gives me crickets. Sadly closest ethanol-free station is about 70 miles away.

Well, you should do a little more research to understand that the In Tank fuel pump ( which is the one you replaced and I've already replaced twice DW265c and Walbro 485) is not the one that chirps.

The on that chirps is the High Pressure Fuel Pump which sits in the engine bay just north to the drivers side port injectors. There are no aftermarket high pressure fuel pumps.
