Best Settings with xHP for 1/4?

[Booly]

Hi,

my supra (semi slicks, 275/35) has mhd stage 2 (102 Ron) and xHP stage 3 software on it, and my problem is, that my launch control is brutal ass, my car legit does a burnout till 3rd gear or it comes with a boost lag, where the boost randomly kicks in at 100kmh where i almost do a 360... any ideas what settings i could use on xHP with to make a valid 0 - 100 time without destroying my 100 - 200 time?.

(The Drag mode is so weird, everytime it upshifts it feels like im getting backshots...)

Thx!

there's more to it than a tcu tune..

don't use launch control (it's horrific), seek a custom tune (you mention boost 'randomly kicks in'), and:

although i advise DO NOT turn off VSC until you are confident with your launches. the goal is to get the car back home, yeah?

What are "semi slicks"

XHP settings for Drag Racing
- Disable 1nd Gear/Always start in second, there's a force option, do that
- Disable kickdown.
- Max RPM, set to your appropriate RPM for engine build/turbo
- Stage 3.

Follow above screenshotted advice.

@zrk Semi-slicks are what they call tires that are road legal but grip well (like our super200tw tires) in Europe.

Tires like the Toyo R888r, so track tires are referred to as “semi-slick” here in Europe. We don’t have drag radials so it’s about the best it gets here.
