Making Hypermiling easier with Buttons

[gascort]

True; I'm not removing all power from the ecu; just removing the main power to it. Since I wired it from the ignition switch, it's exactly the same as shutting off with the key. Just like your stereo always has a power source to save your radio stations, the ecu has additional wires to save its memory.

Nice. I'm considering at least adding an engine-kill and starter button to the xB, so I can EOC more. I found wiring diagrams, now I just need the nerve to go ahead and do it. Granted, I won't go to the extreme you went, killing power to everything, but just being able to start and stop the engine easily would be nice.

Of course, I can't find actual information from anyone who has done the same to their box, and every time it comes up on a Scion forum, the idea is greeted with derision and accusations of rice, with no actual information provided.

Hello,

The switch I want would let me turn off the A/C when the windshield defrost is on. On my Scion xA, you can't have the fan blowing air on the windshield (only) w/o the A/C being turned on...grrrrrrrr.

Ever drive in an ice storm?! (You don't need no stinkin' A/C, that's for sure!)

Sorry, nothing useful to add to this thread :-(

I've suspected that the xB has this "feature" too. I use the defroster setting as sparingly as possible, as a result, even though I've never heard of it specifically. This is common to a lot of cars. Some let you disable it by simply turning off the AC, whereas others don't let you know that it's even on.

In the Subaru I had previously, I disabled the AC-with-defrost by taking apart the HVAC controls and physically breaking the tiny switch for the AC. It worked well like that. If it wasn't 200 degrees outside, I'd explore this in the xB.

I think ill move my switch to the ecu wire, good concept i skipped over, I went for injectors only on this car.

BTW i LOVE dics on xBz, there are lots of clubs out here in socal and one by one the ones who stayed with steelies are going to space dics just like your avatar there

Thanks. I get a lot of people asking me about them-- they don't seem to make a difference with FE, but they look great, which is fine with me.

I can kill the engine by turning the key back about halfway to fully off which leaves all the electronics alone, but I do slip every now and then and kill everything which is more annoying than anything. Buttons would be handy, but not necessary.

My car has that "feature" with the A/C on the windshield. Supposedly it dries the air which helps eliminate the minor condensation which is the fog, but it worked fine in my Focus that had A/C optional...

Yeah, exactly. If I really need the AC on to dry the air, I am entirely capable of turning it on manually. I never missed it after I disabled it in the Subaru, and the GMC I had before that didn't even have AC in the first place. At best, it's not that necessary.
