Does any one know if these do anything at all for the Scion.

any help would be great

hnefrdo has the Pivot brand voltage stabilizer and he swears by it. He said he noticed a difference, and so did his sister's boyfriend (when he drove the xA)...

I'll probably get the Pivot Raizin kit, as well...but later down the line. A voltage stabilizer with ground wires is a good combo. :D

I've got the Sun Voltage MR system on my xB w/ a ground kit by Ground Fusion. Probably not getting any hp (perhaps one horse) out of this setup, but I noticed better throttle response and smoother idle. Where it may be helpful is if you are taxing your battery and then start to demand power at higher rpm. Its sort of like a battery reserve (like a cap for an amp).

Guys, does it actually improve fuel economy? I currently have ground wire system. I am curious of how much improvement it makes in addition to the ground wire system... :?

Scion experts please help!

don't know how much of a difference there is but they sell the same type of thing on ebay for like 70 shipped.

Thanks guys.. I will also check out the Pivot.. wasnt expecting HP to much just wondering about the throttle response and fuel economy stuff

Thanks Alot

Resolve, you try a ground wire kit yet? You can build your own for cheap! https://www.scionlife.com/forums/viewtopic.php?t=29261

All I have is my "Mikochu Über Ground Wire System (v2)" right now. I took my v1 ground wires off and noticed erratic idle and the throttle was not as responsive as with the ground wires. My v2 ground wires was optimized to 4x8 gauge wires (v1 was 6x10 gauge wires) and it does the job. Idle is smoothened out and the throttle is much more responsive. I probably won't buy a voltage stabilizer until I have money to burn...but I'd make/install ground wires first.

I don't have plans on selling my kit, but I encourage others to make their own. I had some wire left, so I made a kit for TakumiJr and Kara. I won't be able to get Kara's kit to her until later this weekend, but TakumiJr got his and he says they really made a difference on his auto xA...

With the fuel economy, I don't think you will notice a difference... *shrug*

I might just build a hypervoltage kit myself. It's just a bunch of capacitor working at different frequency rate. Everything you can buy at Radioshack for less than $30..

Thanks mikochu i will do that.. was definitely going to do the ground wire just havent gotten to it yet..

Finally, I finished making the hypervoltage systme myself!, on Thursday :D It costs me about $30-40. Parts are from Digikey and radioshack.

I connected it to battery. And the results......

My car is quiter, has less vibration and respond faster. It shifts more rapidly. I am fully satisfy!. Lights are also a little brighter.

ECU also need to learn about this mod to adjust some parameters for a day, I guess.

However, I feel "little" change in power at steady speed. I will post some pictures soon.

If you guys are interested, I will write it up in more detail.

please do, along with instructions / schematics / pics.

Thanks!

Wait until I take a photo of it. It's freezing over here. I'm too lazy to go outside to take a picture

Resolve

yes pictures and instructions will be nice..
