You start with 2 buckets. A full bucket of luck and a empty bucket of experience. When the bucket of luck is empty. You hope the buck of experience is full. If not. You're in deep dodo.

Seb is my tuner. He said he has setup failsafes on my tune.

Not sure if you read my last post, but for remote tuning purposes I have to have VDC off, or it skews the logs.

Seb recommends the Greddy Profec, can't he help you set it up?

Interesting.
I'm supercharged with 450whp and 364ft/lbs which comes on a lot earlier with the Si impeller upgrade I recently had done. I have the Cusco 1.5RS LSD which uses a clutch plate system rather than helical gears like the Quaife LSD has.
When the same situation has happened to me with VDC off and I've applied to much power in a straight line and I break traction, typically the back end of the car kicks out to the left and occasionally to the right. As soon as this happens I back right off the throttle and the rear of the car instantly kicks back to being straight again. The rear has never gone from left to right or visa versa and approaching a complete spin out.
I wonder if the Cusco clutch type as opposed to a helical gear type LSD assists with this? :driving:
Maybe I lifted off quicker...

Oh well since your tuner who isn't there and doesn't know you from a bar of soap asked you to do a WOT pull with VDC off, you should probably listen to him without thinking if it's a good idea....

the very fact you're asking "hey my car suddenly went sideways and I almost crashed, what gives?" on a forum means you are in over your head.

Your SC setup doesn’t have the same torque curve as a turbo. It’s not even close. When the turbo spools up you literally get 250/300 extra ft-lbs in an instant.

Jwick is rite. I am around the 840nm (620 ft•lb) engine torque according to my Ecutek logs, which is probably more closer to 620nm (450ft•lb) wheel torque @3500RPM

Well my tuner is one of the best for this platform if not the best. And after I told him what happend he updated with another tune for me to try, possibly one with better traction control? Not sure, havent tried it yet.

:iagree:

Seb is the man!

My original tune before I swapped exhausts was 500whp and 480wtq. Trust me the difference in just 40wtq is very noticeable when you get it all at once.

Everyone always boasts about HP but it’s torque, and when and how it comes on, that matters.

Yeap, Seb can tune that part of it. I sure he made some adjustments for that.

Right, i actually crashed, and then had this same thing happened to me 3 more times, but those times i was aware of whats going on. Now to fix this you NEED to do is pull the VDC fuse in order to completely turn it off because it does this.

The other thing that helps is the experience so next time you’re ready with lightning reflexes.

Guys, should i get the FUSE removed to completly disable VDC? Will this work out better or more safe for my WOT pulls with VDC off?

Do I need to tel Seb that I am going to remove it or will it not matter?

Definitely run it by Seb before you do it, he'll tell you if you should completely disable it for your tune.

You don't need to do the fuse removal or need to disable your ya sensor. The Ecutek works very well. Seb will make need adjustment as your throttle response may be to sensitive in that is it comes on hard and fast. He can adjust that so that response is slower.
