A clutch bypass should have no effect on it; I've done it both holding and not holding the clutch down, as well as in gear and in neutral...

I know a tech who said there was a way to turn it all off but he wouldn't say how. I don't think they're supposed to divulge this info.

Well, I did the pedal dance right. Mike's procedure worked for me, though it took a while because I kept trying before the car warmed up. It might be easier to use my techstream cable. I worry about pulling things from the OBD port when the engine is running, and I won't want the laptop in the car all the time.

This should almost be a sticky thread.

Ah, now I get it! This is the third thread mentioning "the pedal dance" but not the real effect.

So, now someone with Arduino smarts should create a little board that performs the 'dance' with the push of a button. I dread having to do this before every track session interval.

Thanks for the info, OP!

This reminds me greatly of a scenario I experienced in my last Autocross (). Thanks for testing this out for us. I'll have to check it out myself the next time I go out.

Ok the secret is out I guess...
Just be very careful as the FRS is a rapid responding car and if the driver isn't quick and accurate and very versed with dynamic car control, things can get hazardous pretty fast at high momentum inputs. We learned on analog cars like this in the past with older cars, but threashold was a lot more forgiving back then with moderate tires and compliant frames, chassis and suspension.

This car is like driving a Lancia Stratos or a Lotus Elise when it's fully analog, and if you ask anyone of age who know them, you'll understand what I am getting at here.

Go for it! But stay safe!!

This was posted in September by @086A who found it in the repair manual. This ft86 system is called auto lsd it's like a supplement to the diff where the electronics apply abs pulse to the loaded wheel when the lsd is struggling.

It's already done. Search for 'VSC cut'. Autofactory was one of the earliest. http://www.autofactory.jp/product/to...?mode=s&seq=14

Just wanted to add, Yes the normally available TRC/VSC full off will function almost the same.
The VSC intervention in the all off mode from 3 sec press of TRC switch, normally available will allow almost all but the largest of slip angles, and allows you to be sideways pretty much in most all situations...

What you get with this additional step is the ABS function to turn off, leaving you with fully analog car. But in most cases the ABS is a completely beneficial thing and unless you're training to be a better all-around driver, the ABS should be left on so you're not flat spotting tires or losing precious seconds off the lap by having it being off.

It's not a performance enhancing mode really, it is more a diagnostic mode for benching the car's performance without electronic intervention.

ABS is still active in this mode. What it does is disable VSC, TC, Auto LSD. I agree with you though people should be careful!!
