:eyebulge: Are those numbers right?!! Holy hell-monkeys...

I guess my biggest question is, how reliable are the $2.50 ones? I mean, will I be constantly getting false-positives lighting up on my dash? (Not so much concerned with them not working quite as well the other way, because I actually check my tire pressure regularly.)

The 1st link is the actual sensors

the 2nd one is just a valve kit.

Someone needs to cash in by producing a "pipe bomb" for the sensors so I can throw my money at them instead of going to home depot and making my own :)

Ah. I feel like an idiot now! LOL... In my defense, don't have a whole lot of experience with these things; every car I've changed wheels on before hasn't had them on there.

Assuming it doesn't affect the ability to disable tc/vsc I won't run tpms in my other set(s) of wheels :) I can ignore the light.

remove top of dash, remove cluster, remove TPMS bulb, re-install cluster, re-install top of dash. Hmm, seems cheaper then 92 bucks a corner and would probably take less time then having the sensors installed.

That won't work because the Subaru TPMS works off of movement. They don't start up until they are in motion, and since they won't really be moving in your truck, it won't work.

True, but I really doubt it. Can we use the sensor from stock wheels?

Black tape is even quicker :P

However, both of those solutions only work IF the car doesn't prevent you from disabling TC/VSC. Older cars didn't give a crap, but some newer ones force TC/VSC on if the TPMS system is malfunctioning or if a tire is low.

I believe so.

I agree

:happy0180:

On all of those links i get taken to www.tirerackwholesale.com asking me for user name and password. :(

sorry it was just information if you need them you will most likely have to call them and order.

Pricing will be different as well.

Sure you can just swap them over to the new wheels but I am guessing this is for people who want to add a set to their aftermarket wheels so them dont have to be swapping them over. Im for just getting another set but make sure you know what is going on with these as far as registartion numbers are concerned.

I didn't know this... and am bummed. I did the pipe bomb with my Tundra and figured I'd always do it from then on. :(

If Subaru and Toyota didn't take into account that enthusiasts would want to change to aftermarket wheels and put a system in place that will not allow you to disable TC and ESC, I will roll my BRZ off a cliff. I know how to check my tire pressure, and I don't need a sensor telling me!

Well you do know TPMS's have become standard in many countries today by law. If they had their choice I doubt they would have put a TPMS sensor system on it at all for tis reason.

I have a 2008 S2000 and I ran into the same problem when buying new wheels for it.
My solution for the TPMS was to buy a TPMS scan tool to reprogram my aftermarket sensors that I bought for my aftermarket wheels.

I have an ATEQ VT55 that can reprogram almost any sensor on the market and is the same tool that many dealers use. I have the OBDII version which is needed to reprogram Asian vehicles like Toyota, Subaru and Honda.

The aftermarket TPMS sensors that I bought are the new VDO REDI-Sensor which is designed to be a universal sensor that covers many OEM TPMS sensors and costs way less on Amazon.com. I am sure it will be compatible with the new FR-S/BRZ.

At first I thought the TPMS was stupid too, but one day I got a TPMS light and I discovered that I had a nail in my right rear. A few weeks later the light came back on and I had another nail in my left rear. I was glad to have the TPMS because I would have been stuck with a flat eventually if not for it.

If any of you guys are near the Northern California East Bay area, hit me up and I can help you with your TPMS sensors reprogramming

Hopefully we can use those universal sensors. TireRack now has the sensor listed for the FR-S, at $396 for all four :eyebulge:

I installed aftermarket wheels today and left the TPMS's in my stock wheels. No light yet... after 20+ miles. I guess that I'll pull the bulb if it ever comes on.

You should be able to remove the TPMS off the stockers and place them on your new wheels. I had this problem on my evo so I just brought my volks with the new tires to a perfomance tire shop and they swapped the TPMS sensors from the stockers to the volks. The tire shop just charged me for the mounting which was in total $80 :party0030:. Saves me the $400 on new sensors and a $100 charge to get them calibrated to the car. TPMS isnt cheap break one and you'll have to pay for the sensor $100, valve stem $4, and recalibration $100 :thumbdown:.

I installed wheels last night with TPMS sensors in them but have not had them initialized by the dealer. Same story, NO TPMS light yet after about 20 miles so far.

If they're charging you $100 for "recalibration" you're getting ripped off. With the right tools this should take all of about 5 minutes.

Yeah that's how much Mitsubishi will charge. I just swapped the tpms sensors rather than buying new ones and getting them recalibrated.

I have a special order wheel/tire/tpms package in my tire rack cart right now. Looks like the tpms sensors they're saying are compatible with my BRZ are only $66 each. Little easier to stomach, eh?

Much better than $400

Hmm. I've been looking at the electrical wiring diagram for the various systems on our cars and it looks like it may be possible to override the TPMS sensors where they plug into the VSC/VDC control module. I may throw the stock wheels back on the car and get out the voltmeter to see if we can simply 'copy' a valid reading from the 4 sensors and then replay this using a simple circuit. I may be way off in thinking that it would be this simple but it'd be nice to be able to cheat the signal rather than getting into CAN BUS hacking.

The schematics looked like the same module does the radio for the TPMS and remote door locks. It also looked like it plugged directly into the CAN bus.

I was hoping there would be a separate module that talked to the instrument cluster directly.

The TPMS are made by Pacific and are the same as the 2012 Camry. I'm sitting in a meeting talking about them right now. I work for a TPMS manufacturer :)

Well tell them I will pay good money for a module that let's me switch wheels without having to hit up the dealer. Whether that's sensors that clone the IDs of my existing sensors, or a box I use via obd port to program, don't care.

Cloneable sensors already exist, Orange TPMS makes them but you need a special tool to program the sensors. Also the ATEQ quickset is a good affordable option for programming via OBDII. It gets a lot of complaints but I've had mine for a couple years and think it works great.

We just need someone to make a TPMS emulator.

It's very possible to do, but I wouldn't expect to see any commercial products out there since it would be against the law in many states to use.

Let's just say I'm working on/with both of those companies on some awesome projects right now. :)

I think a lot of dealers charge minimum 1 hour labor for most non oil change type jobs. It was annoying trying to get a quote from dealer for caliper replacement on another vehicle. They refuse to give a quote without inspecting and they charge 1 hour for inspecting which is "free if you get service from us"...

Trying to work on a $100 tool that can do the relearn for you. It will pay for itself compared to one relearn at the dealer.

The ATEQ quickset at $150 already exists. Given how much sensors themselves cost I don't think anyone's going to come out with a tool for less then that.

Another possible option for the BRZ/FRS is the Toyota Techstream software. It's officially something like $1500 but you can get it with the cable (probably not an official copy) off eBay for about $40. I acutally ordered one because I wanted to check out some of the other functions. When it gets here I'll be reporting back to let people know if allows reprogramming of the TPMS sensors.

Someone selling Techstream software on eBay?!
All I see is $40 OBDII cables that support the protocol Techstream uses. Are they throwing in software unofficially or smth?

Techstream w OBDII interface that supports "J2534 passthrough" can access/program TPMS IDs.

Yep tones of them just search "Techstream" and you'll see lots of them with cable and software. Mine should get here sometime next week, I'll let you know once I' get it and have a chance to check it out.
