A-Trac

With all of this rain, ID LOVE TO GET RID OF THE A-TRAC!!! I have been reading up and I guess i have to cut the wire. Is there another way to do this without messing up the wiring harness?

I infer you do not think locking the central diff disables VSC? I thought so..

there are benefits to being able to cancel the VSC and remain in HH (w/the 6spd) or 2wd (w/the AT)

Explain...

On the manual transmission we have:
1) regular 4x4 HI
2) central (torsen) diff locked 4x4 HI
3) central (torsen) diff locked 4x4 LO

now, to my knowledge 2) and 3) disable VSC, don't they?

H=regular street driving
HL=central (torsen) diff locked 4x4 HI; VSC is disabled but TRAC is still active
LL=central (torsen) diff locked 4x4 LO; VSC, TRAC is disabled and ABS is disabled when A-TRAC is active

sorry for the typo I ment to simply type H not HH

running around with out VSC would be fun with 30/70 F/R split and letting the computer figure out where to sent the power

I guess maybe it's a difference in driving style or something. But I really can't understand what the big deal is and why so many people want to get rid of VSC. I've never had this issue of losing power when I "get on it". I have, especially when I first got my FJ, actually TRIED to lose control and when the VSC kicked in, all it didi was yack me back the way I was going. I didn't lose control, nor did I lose power or momentum. I've never had it do anything I didn't want it to do and it's never caused any problems. Then again, maybe it's because I drive my 4x4 vehicle LIKE it's a 4x4 vehicle and not like it's a Corvette. I think if you want to drive like a nut and have fun on rainy streets and stay in control, buy a Subaru WRX.

I dont know if this is the same but my 09 has a button to turn off the traction control. Squigilly lines with vehicle above them is whats on the button. So maybe you could install this button and hack into the wires.

If you go on a trail that has bumps and slippery surfaces, but does not require low gears, having VSC active is a *real pain*. The FJ will beep at every such bump, then it probably tries to do something by cutting power or using the ABS system, and you hear all those relay noises and feedback on the pedals. When going to low gears VSC is cut so the problem is not present there.

I see a real need to cut VSC, for those trails that do not require low gears.

On a manual, I think I solve the issue with the setting to lock the central diff.

It seems Toyota acknowledge the situation by introducing the VSC kill button on 2009 models.
