Chassis limited function code. A friend of mine put on Sway bars and after the install he drove home he got the Code car drives fine would it be a problem on track day??
Second question though for anyone, got a track day on Sunday and if I don't get this sorted by then would it be safe to track the car? Again car feels completely fine. Feels really good actually lol

If it is the sensor yeah it's safe. I didn't get any limp modes on a few rowdy autocross runs before I figured out what it was.

I wonder if I should get spare sensors just in case they break or snap.
If you've got nothing else to spend ~$75 on and hate dash lights then go for it. It's the arm that is more likely to break. Looks like it's only $10. https://toyotaparts.bochtoyotasouth...xJmw9MiZuPVJlY29tbWVuZGVkIFByb2R1Y3RzJms9MQ==

I just snagged a set of CRS V1 in a 275-40 for $1k. They only need to last four events. Talk about "score" ????
Waiting on an invoice from PhD for some V1 CRS, Titan 7 TS-5s, spacers, and stud kit. ????

My biggest fear was that the “nannies” would come on slowing me down or she’d go into limp mode. None of that ever happened. In fact it was just the opposite. You couldn’t turn them on. Which was great! Traxion is right. That thing is just floppy, looks and feels loose. But it’s just the way it is. My mechanic told me mine was completely normal. So now I pay a guy that’ll come to my house and can code out anything. Turns out a windshield installer has all the tech/computer tools to do so as well as a salvage yard guy.

(I no longer needed that particular code fixed after I got Ohlins and my ride height is now closer to normal - but I did code it out prior to that)

I did the same ? after I told myself I was going to buy v2. Then I saw the close out price, thank to the heads up from Rock!! Even Maxxis went up in price. So these were a no brainer

Someone makes a replacement bracket and arm for the sensor that's made out of AL and supposed to be stronger.

Anyone tried that and does it make a difference?

I have it on my car, but only because I felt like it and not because there were problems.

Here is a pic of the rear ride hight sensor. Is on left rear. Have to pull tire to get to it or have it up on a hoist. I expect when they changed the rear bar they could have broken this or pulled it off when they dropped sub frame.

Yup, it's SUPER easy to break that grey plastic bit attached to the lower arm when doing suspension.

Went to a new to me track this weekend. Thompson Raceway in North Eastern Connecticut.

Fun track but I finally experienced fuel starvation about six times. A good amount of sweeping right turns at this track. Ironically the section where other supras have experienced it, I only got some "light" starvation where the car would just kinda stop accelerating like I let off the throttle, and then in this right turn that is nowhere close to g-forces I was experiencing in the other section, I got MASSIVE fuel starvation on WOT coming out of the turn. Huge backfire and it felt like I hit the rev limiter. This was only with two bars gone on the gauge too, so about 3/4 tank or more.



In the logs, the HPFP crashes hard at this moment.

I might have to limit my trips to Thompson, or get a fuel starvation solution, which I really do not want to do.

Just means that you’re going fast. No way to avoid it except to lift… even then you’ll still fuel starve a few laps later.

Holy shit! I didn't realize it was that bad for you. Turn 8 to Turn 9 has some crazy surface and camber changes. It scares the hell out of me if I hit it wrong.

Your car looked great out there if that's any consolation. It was the first time I got to see a Supra at Thompson. There's some great viewing spots where you can spectate (lots of locals come to watch), and seeing your car on track was absolute ?

You need an exhaust lol. The Supra is like a whisper compared to the other cars out there. ?
