Hi All,
Been trying to tune my Rx7. And using RKM's tune as a basis and going from there.

But something i've been unable to tune out is the massive amounts of braking oversteer i get.

So running on Tsukuba, the first 2 corners.

Brake hard, initiate turn, while trail braking.
And only when i lift off the brake my car goes into snap oversteer.
( i have not put any throttle yet)

My ABS is set to 1.

From a technical point of view i'm not sure whats happening? when i lift off the brake the front end grips more? sending me into a spin? or isit the weight transfer to the back when i lift off the braking causing this spin?

I've heard of lift off oversteer from throttle perspective, but never heard of it from a braking perspective.
 
Somebody will probably disagree w/me but I'd turn up the brk on LSD then maybe initial also.Haven't looked at their tune but this is just off the top of my head.
 
Drop the rear brake bias down a few clicks; it doesn't actually cause oversteer when you're at full braking but as you breathe off the brakes the front will have less braking force than the rear, causing oversteer.

Or, as that behaviour can be useful at times, you can just apply a small bit of throttle while braking and it'll calm down considerably.
 
did some testing yesterday, hrm while it did help, i had to turn it down a fair few clicks, from 9 down to 4.

although i did notice that maybe i'm not trail braking correctly, as i normally just fully lift off, i found if i lift off a lot more gradually, i dont get this effect as bad.

thanks for the advice peeps.
