From "stay tuned" to T U N E D !!

How long after you enter the wash does it toss a code? Video of it? Just curious.

It comes on after I leave the wash. The original one lasted a calender year of use, the replacement one lasted for 6 monthes of car wash use.

Well hopefully replaced and then good? My understanding is is they replaced it once?

Yes, back in July of 2023

I found this video on YT, from six months ago. I'm not trying to single out your choice of car, or upset you, but the knock sensor makes number 1 on the list. It seems like Hyundai are fully aware of this issue. They really have to come up with a fix for this. If they have bought back vehicles that have the front parking sensor issue, then they need to do the same for this.

No worries Dave and yes, they know this is an issue and I was unaware of the parking sensor situation

I'll be talking to corporate today, God only knows what they'll say

With the parking sensor issue the guy did say it was possibly dirt related, so that's not really a problem for you.

All vehicle models have their known issues though, I researched the FJs before I bought one, it had been on the market long enough for me to be able to do that. Saggy suspension, not worried because I was going to lift it, transmission failures, fixed before the year model I was buying, rear brakes inadequate, still waiting to fix this, I'm on my second set of pads, and the rear discs are warped, they're solid discs and I'll be replacing them with vented at least. Meanwhile I still haven't had to change the front brake pads and that's coming on 7 years and 90,000 km. Did they have different teams working on the front and rear brake systems or what.

Fingers crossed for you Roger.

So sorry to hear the problem isn't fixed. I guess the silver lining in this is after all the work is done, it focuses the problem on bad sensors.

If the sensor is known to be bad, you'd think by now there would be a revised part in the part system by now. Even if they didn't do a maintenance campaign to swap them all out, the problem would fix itself as warranty repairs take place.

When I owned my Mk6 GTI, they had an issue with water pumps and across that generation there was something like 4~5 versions released until they finally got it right on the 6th one. VW was well aware of the issue and issued a maintenance campaign to fix them, even after the Mk6 had ended production and many of the cars were out of warranty. Hyundai needs to do the same.
 
My car is ready for pick up...they replaced the knock sensor

You guys need to check this out...HOW TO OCTANE LEARN this car

ECU tune w/o octane learning is MUCH easier

Interesting. I thought most ECU's did that on their own in real time based on various sensor inputs. Does the car have a recommended octane level? If not, that may be why this procedure is listed. Otherwise you can get some knock running 87 in a car that should be running 91 or 93 octane.
 
It "can" run on 87 but I ofcoarse run 93

I've found 93 very hard to find west of the Mississippi river. It's everywhere here in the St. Louis area, but the further you go west it becomes hit/miss.

The last 2~3 cars I've owned and none in our current garage can run on anything lower than 91, which means we get 93 here since the choices are 87, 89, or 93.
 
Up here we have, depending on the gas bar brand, 87, 89, 91, and 94.
I have always wondered how long the octane lasts sitting in the tanks when prices are insane? I mean, when I let my car sit all winter I add stabilizer on my last fillup before it sits. I imagine the tanks at stations are just topped up on schedule to take care of that??
 
I think it would depend on the station and how much business they get.

We have a couple of small local chain stations on residential roads that never seem to have more than a car or two at them and I bet the gas in their tanks are pretty old. Less than a half-mile away are several larger stations on main roads whose pumps are rarely idle. I'm pretty sure they're getting topped up at least once a week. I've seen tankers at our local Sam's Club gas station at least a couple times a week.
 
**** U P D A T E ****

The original ECU is heading north of the border to get its "Masters Degree"

I chose:

-Stage 1
-no octane learning
-stock redline
-standard crackle tune
(Mid-Pipe is enough)
-93 octane tune

Also because it's the same price, when my new TPMS come in for the KN rims (also from N75) and they get installed, the Michelin Pilot Sport 4s will be going BACK on!

OEM Michelins are 245/35/19's and the Kona N OEM size is 235/40/19's. I mean they have 6/32nds and aren't bad, well besides they're Pirelli's ...and aren't Michelin Pilot Sport 4s that is️️️️

Not sure when that swap is happening as those who know anything about Midwest early spring weather...it's like a box of chocolates, although it's truely trending the right way I must say

Exciting times coming as another trip to the dyno is going to be happening, I'm leaning towards the shop Savagegeese uses, it's an AWD Mustang dyno. I know it's a tool and whatever the number is is the number. Sure, everyone wants the "big number" but the correction can be factored in afterwards, telling me what my advertised or crank hp/tq trurly is...stay "tuned"

Btw...no touch-free washes since getting the 2nd knock sensor, I've just accepted that the car can't handle it over time, maybe some engineer at Hyundai can figure it and until then I'll join everyone at laughing at a car that can't handle a carwash 🫣

It does seem a little baffeling from a company that builds millions of cars every year. However, your in good company. Most Lotus Elise's can't go through a car wash either because of all the leaks!

Atleast it can be wiped up, LOL

I went to college with that guy, and his car was the example I was thinking of! He's joked about it on their podcast for years on since buying that car. I've heard it form a couple other owners too.
 
Just did a 0-60 mph pull:

Previous pull was 5.79 w/2800 launch control and no NGS. This time I got 5.57 w/2500 launch control and no NGS. The tires were spinning almost entirely through 1st gear. I'd guess about 17 psi of boost here but that's max, always drops 1-2 psi

My previous best was 5.41 w/the Kona tires & wheels and my N75 Stage 1 ECU tune, wheel hoppin' and makin' about 20-22 psi, tires closer to half worn FWIW
