Who doesn't enjoy a nice hole in their powerband?

Maybe it smooths out the acceleration when the engine is on cam, because that would just be tooooooo much power.

It's an engineered time to catch your breath between power surges

The sound with Bluetooth is fantastic. I'd thought the speakers were crap until
I used more Bluetooth audio

Why would an iPhone 6s sound worse with a lightning cable than USB?

It sounds the same both ways in the Miata

 The car has TPMS sensors, but the car only uses a dummy light on the dash.  I can't read individual temperatures.

I've learned something interesting.

The sensors actually read tire pressure and temperature!  I'm going to see what kind of solution I can get so I can see this data in the car.  As of right now, it looks like the best bet would be an openflash tablet and to edit a ROM.  Which might be good to recalibrate the throttle also.  But I'll wait until the car is out of warranty and maybe even after that. 

I'd like something like an OBD2 adapter that could read this data to my phone (or in the future, to a new head unit), but this data is hiding within the ECU/CANBUS (I have no idea what this would be called) that I don't think the OBD2 can get to.


I only went down this rabbit hole since I'll be buying some new wheels and tires for daily use, and new tires for stock wheels for AutoX.  The TPMS sensors are outrageously expensive, I figured to pay for their additional cost I'm going to need to get some information from them if I'm going to pony up to keep TPMS sensors around.

They make some decent double DIN Android headunits... you could get a BT dongle. Still doesn't solve the issue but would be cool to do

PLX makes several adapters that will BT connect to any phone, but some of the more specialized OBDII data needs proprietary software to interpret. You could also use a program like Hyperterminal to access data from thhe bus directly, but you'll have to figure out which node is the TPMS adapter and what the raw data means

[AutobahnSHO]

there are Adroid/iPhone apps for OBDII, I can't remember what I got but it wasn't free. (Can't bring phone into work).

[Rich]

I have the automatic app for my iphone... I know Torque is a good app, but as far as I can tell, it doesn't have a PID for the TPMS

[2o6]

Soup is right, a lot of that stuff is proprietary. You'd probably need a Toyota-specific tech tool. (What's the equivalent of a GM Tech II for Toyota?)

[Soup DeVille]

Torque Pro can do it; look under settings and "manage extra PIDs." I don't know about regular torque, but there seems to be an add-on in Dash Command (another app) that claims to do it.

Hmmm.  As far as I can tell on the FRIZZ/BRIZZ forum, no one has this figured out yet.

[Rich]

Also, new wheels and tires will be happening

The stock wheels are getting RE71's strictly for DS class SOLO

What should the new DD wheels be?  What tire? Stay stock 17" sizes?  Go wider?  Go 18"?

[12,000 RPM]

Stock size + more aggressive offset + stickier tires. No need to overdo it

[Rich]

Thinking about all seasons since it dipped below freezing many times overnight this past winter.  I've heard that driving summer tires in freezing temps is no bueno for the well being of the rubber.

Depends on the tire.  Pirelli says don't drive at temperatures under 40F or else risk cracking the compound.  I think Michelin and Continental say 20 or 25 F for their hi-po street tires (PSS type, not the 200TW autocross gumballs and R Comps).  They all start getting noticably greasy under 50F until you've driven a bit to get some heat in them.

RE-71R for autox and BFG Comp 2 A/S for the street is a good mix. The BFGs have plenty of grip in all temperatures for street driving.

Some of the post 2016 Toyotas seem to have the TPMS connected to the BCM bus and not the ECU bus, which would complicate things.

3 sets of wheels/tires when you are out of the country a ton seems like overkill. Also what is your storage situation... yea I would go with all seasons.

[Xer0]

My winter tires are all seasons and I have a separate set of summer tires for, well, the summer.  Not sure how the BRZ is in the snow, but the Civic has no issues handling Chicago winters in A/S.  FWIW, they are the Pilot Sport A/S.

[Rich]

I made an offer on some used 16x7 +46 SSR wheels on eBay for AutoX.  Lesseee what happens.

[12,000 RPM]

Will they cover your brakes? Offset is not Sporty approved.

[MX793]

Offset has to stay within 6mm of stock to stay in the "stock" class with SCCA.

[Rich]

Yeah they will. I don't have big calipers. Stock offset is +48

[Rich]

The plan is to put RE71 Tires on these wheels and when the stock tires wear out from DDing, put some Michelin pilot sport a/s on those.

I'd love to get some 17x9 concave wheels but cost, weight, tramlining, noise, and gas mileage factored into bailing on that

[12,000 RPM]

Get 245 width Prius tires.

[MX793]

I think the stock wheels are 7".  I don't think a 245 will readily fit.  I think 235 is about as wide as the wheel will accommodate.

[MrH]

If only there was someone on the forum who had a BRZ and ran 17x9 with 245s...

Dropped the hammer on 16x7 +46 TE37s in white.  11.5lbs vs 21lbs for the stock wheels.  They will be getting RE71s for AutoX.  About the time the RE71s wear out, the stock tires should be toast from DDing.  The TE37s will then go for DD duty (wheel weights make a lick of difference on track, but should be much more noticeable on street).  I don't think I'll like the white so I might get  them powdercoated then too.
