Toyota Techstream

Can somebody just name a few examples of what you can change with Techstream? Anything useful besides TPMS stuff?

Click on the Techstream Demo link after you click here, to see some of the stuff.

Dumb question. Can you reset the ECU using Techstream? I couldn't find an obvious way. I had no codes, so the ECU screen in the software is mostly a blank screen. I'd just like to be able to do it without pulling a fuse/battery cable.

Yeah, bottom left of the screen. Looks like the CEL on the dash. I couldn't figure out what it was so I clicked on it. It ask if I wanted to clear all of the DTCs.

I tried this yesterday and have one question. You can change the Auto Lights settings for the BRZ, Dark1 Dark2 Light1 Light2.

I know in the BRZ Manual it says this can be adjusted to -40% -20% +20% +40%

So I was wondering, which one of these numbers corresponded to the Dark/Light 1/2.

(My guess is they work accordingly to the order I wrote but its always good to have confirmation).

It is going to depend on what version of the car you have but for example on my BRZ limited:
Driver side Seat Belt Chime
Passenger side seat Belt chime
Head light sensitivity: dark 2 dark 1 normal light 1 light 2
(I am assuming that it comes on the earliest with light 2 but I am not sure)
A whole bunch of AC controls that I left alone
How long/when the interior light comes on
Several option for the door locks (depends on model)
(The list goes on)

If you are at all technically minded I think getting this cable and software from ebay for $30 is an absolute no brainer. Caveats are that it is possible, if you are not moderately careful, to mess up your car & that the software's user license is "dubious"

Yes it is. If you're using your own computer/laptop, it is definitely TIS Lite. Look here for more info:

Ok, from a Tundra document it looks like it goes from

dark <--------------> light

dark 2 -- dark 1 -- normal -- light 1 -- light 2

One last thing, the dark 2 setting means it will be darker before the lights come one, while the light 2 means there will still be sun and the auto lights will come on?

That is how I read it. Just from a curiosity perspective are you trying to adjust your headlights so it comes on when it is lighter or darker out. I want them to come on when it is lighter out.

I need to adjust them to come on when it is darker, so I'm guessing trying dark 1. I have a tinted windshield with 80% film and want to compensate for that.

Oh, that make sense. With 80%, if it were me, I would try dark 2.

But remember 80% in tint terms means 20% protection 80% light passes through, so in reality its a slight change I need. I think 80% protection and only 20% light pass through is a recipe for an accident! I guess I'll try it out on the weekend and post here results.

I need to try it I guess. I don't have any DTC's to clear, so I didn't investigate further. I wanted the ECU to un-learn my slow ass break-in driving.

I swear the traction control also has some learning abilities. I thought I'd screwed it up after resetting the ECU. It seemed to require much more aggressive driving to make it intervene.
