On track having the Yaw sensor bypassed makes all the difference in the world on tight slow speed corners.

Rotation with TC on will result in a nasty power cut. The car feels like it falls on its face.

With TC off using the OEM on/off switch(Yaw sensor still fuctioning) you can initiate rotation but if you go too far the car will still try to correct itself using a single rear brake to maintain equal wheel speed. Feels very very odd and almost causes the car to snap back. Super uncomfortable sensation. If rotation happens quick enough though it will still spin easily. You just can't get to a controlled slide or rotation.

With Yaw sensor bypassed, which also completely shuts off TC(you don't need to do anything with the OEM switch), the car will do as you please. You can initiate rotation, think T2 hairpin at Laguna Seca, get on the throttle, maintain speed while staying in the proper rev range/power band, and power out of the corner. Plus all the slip and slide fun you could ever ask for.

 

This has been my experience when pushing the car too.

 

With an open diff the experience seems to be different. It seems like the Yaw helps out the Open diff tremendously.
Like Roch said 6MT get all the goodies.

 

That is a super interesting data point. I'mma gonna need to seriously grok all the details - while I like and can accept that the car handles better with TC off with my driving style/experiences, I always want to know the *why* too.

I think either an AWD dyno or trap times would give usable but misleading results - I think on decent pavement a straight line acceleration test would show a slight edge to the TC system being on. However- real roads (and tracks) aren't perfect or even or level, and add in the turning component to tighten up the traction circle... yeah, I think that experienced drivers are better at throttle modulation than the computer in the G.

Wonder how the GTR does with the yaw sensor unplugged - it's usually recognized as having better TC than many other street cars.

@BULL again man, you're hitting on all cylinders here. Great work.

 

In my mind I see it only affecting open diffs. GTR would leave all the work to the LSDs but at the same time the GTR is a far superior machine. With how much I've been learning it wouldnt surprise me if the Yaw communicates with the AWD and torque distribution.

 

I remember Clarkson on Top Gear's comment that the GTR has more computers than the space shuttle... or was that the R34 GTR-V?

I wonder if modern car manufacturers will lean more on software to control traction vs mechanical like LSDs...
///Who am I kidding, easy enough to throttle electric motors to do what you want.

I watched a Tesla Model3 spin out out control last year at Auto-X. Did a full 360°... It was pretty shocking.

Inertia is a b1tch.

 

Bet that wasn't the standard driving mode. Just like you can computerize the hell out of traction... you can turn that off LOL. Or set it to goofball mode.

Given the reaction time of the motor controller circuits, you can program those things for almost instant power modulation on tire slip. And you don't need brake reaction time to worry about with an electric motor. But... that's boring. And possibly a little slower than some carefully controlled slip angle.

For most modern cars, the tech is about 5-10 years old at introduction because they need to fool-proof it before it can go in a car. Tesla doesn't seem to care as much about that so puts in what they can get now. Processor speeds in 5 years increase astronomically - I'm sure Moore's Law applies to embedded applications like cars too.

*I* can make an electric car motor controller that give me controllable torque. Making one that has sub-microsecond traction control response is beyond me LOL.

// Can't wait till used car $$s come down... I really want to make a FB3S electric.

 

I'm kinda jealous, my switch is apparently somewhere in the USPS system... Day 7 and counting

 

In Mike's defense he only ordered connectors so it went in a small envelope unlike the kits that went in a bubble insulated envelope which is a bit bigger and much heavier than connectors.

 

In the GTR's defense ECUTEK is the go to application almost all use and being able to dial your traction settings on ECUTEK is a hell of a pro.
With ECUTEK you can disable brake override to be able to burn out and other cool quirks. You still have to disable YAW for RWD for full throttle exits without interference however in a GTR drifting/throttling out is not a concern much are worried about.

 

I don't think he's talking about my shipment arriving - I PMd you it was here but didn't say anything on the forum at large.

 

My G was tuned with ECUTEK.

 

Fixed that for you


THIS IS THE WAY
