New fine-grained VSC OFF Mod for V6 1GR

[Javelin]

They all stay on in 4wd and 2wd. They will come on within 5 min (not pushing vsc)

Onlyway to turn off the lights is to disconnect the unit.

 

[Javelin]

If I push the VSC button right after starting the engine and leave it on, only the VSC off light comes on. Other lights do NOT turn on. Drove for 20 minutes VSC only.

Same as mine

Not good at all. I had 5 items in that batch and all of these are shipped. None of items I have right now working the way you describe. If it makes lights on even if it was not switched on before - definitely something wrong.

Please ship it back. I will ship you new item, which I was running all the day today trying reproduce the same behavior.

Guys, there might be an issue with the installation rather than with the unit. When I do installation I usually do not disconnect VSC ECU connector. Just realized that it might make it lost zero point. It might explain why mods work fine with me but do not in your case. Here is the thread with more details re zero point calibration:

Hope to get the package returns soon to prove or disprove that.

2 Javelin:
There are good news and bad news. Good one is that I received the unit today morning. Bad news - I was running it for 40 min (4WD) while driving to work and had no issues at all.

I found an issue with 2WD, actually. It does not work if you just switch it on in 2WD (It lights VSC OFF LED and that is it). To make it work one should go to 4WD -> switch VSC OFF -> go to 2WD back. Probably, it might make ECU mad if you just switch vsc off in 2WD. Anyway, I failed to reproduce the same usecase as you got.

If that is not an issue of "zero point" lose or some similar stuff -I have no ideas for now. I will continue running the unit you shipped back.

Thats Strange

I thought the whole point of the unit was to be able to turn traction off in 2wd without switching back and forth.

 

[Kliv]

Originally the main purpose was to make vsc off work without misleading center diff lock light. If you bought the unit mainly for 2wd usage I can take it back and refund the costs.

So the only way this mod works is when Im in 4Hi or 4Lo?

 

[Kliv]

Not quite right. It works in 2wd in case 4wd-vsc off- 2wd like original mode.

 

[Javelin]

Is there a way to Permanently disable VSC without the light coming on.

Or permanently disabling VSC then disconnecting the light?

I really don't need it. Its more of a hindrance than anything else.

Is there a wire I can cut or a fuse I can pull? I dont care if it goes away forever. In fact I would prefer it.

My device works fine in any mode... 2HI, 4HI, and 4LO, but I did notice that the 4Runner doesn't like to switch between modes with the device activated. I just switch it off to change modes, if I need to.

Well Then, that leads me to believe that my device was malfunctioning, but Kliv says its working fine on his 4R

Mabye my 4Runner is broken

Shame on you Toyota for not putting a traction control switch on the 03-07 4R.

let me know when you're back and producing again, I'd love to get this! My understanding is its $60 + shipping + Western Union fees?

I've been wanting to do the VSC off mod for a while but wanted a cleaner way without switching all around and this is it!

Thanks!

 

[Kliv]

2 jpless:
I will be able to ship one item on Monday-Tuesday.

As for price, you are quite right. It is 85$ CIF for PayPal or 70$+15$(WU fee at your end) in case of Western Union transfer.

 

[Kliv]

Guys! I got the issue reproduced on my truck! It happened during long ride with 2wd. Selling is temporarily stopped till the issue resolved. Will keep you posted.

 

[lexmedic157]

Sort of glad it happened to you. I'm not the only crazy one... Whew!

 

[Kliv]

The answer is in the unit temperature - when it is getting warmer it starts working in a wrong way. We had winter here - that is why I way unable to reproduce it earlier.
Looking for bad guy and solution for it. There are several thoughts. It might be easy to fix without shipping it back. Will keep you posted.

 

[Kliv]

Looks like we found the problem. ALL new units are affected. Long story short: we tried to make it better but as it usually happens made it worse. Thank you for pointing that out and for your patience in describing wrong behaviour. We fixed two units and I've been testing these in different modes (and temperatures )

I will let you know when I'll be confident in quality enough.

To 7 lucky guys who have new units :
If you know how to remove one redundant component from the board (or know smbd who know that) - it will take you 2 min to fix the unit. I will provide description when it is tested.
If not, please send the unit back( just unit). I ll take costs and will ship you new unit. Unfortunately, it will take 1 month+ to have new unit in US.

I am really sorry, but it is as it is.
