Default S300 Launch Control settings for Drag Racing

I have a fully built GSR turbo setup, with a Top mount full race manifold with a t4/s366.

I'm trying to mess with the Launch Control Settings on the Hondata S300 and build at least 10 psi of boost off the line, I would like to see what numbers you guys are using in the Fuel & Ignition Settings.

Activation RPM???
Fuel Enrichment????
Ignition Retard???

I know every car is different but if I know where to start at that would help a bunch.

I think more information is needed. Engine displacement, compression and etc.

Oh ok , here you go

84mm b18c1 golden eagle sleeves, 9:1 compression, gsr head with skunk Pro 1 cams, twin disc, JG intake manifold, bosch 1000cc injectors on e85

It made 600hp/400tq on a t3/T66 turbonetics turbo, about to go to the dyno to see what the new manifold and turbo will make.

try like -20 timing and 20 fuel

they like to be richened up and timing pulled out(as far as mine goes) i can build tons of boost sitting there if i wanted to. activate it about 300-400 rpms before the limit that you set.

wow it seemed to work out... set the activation at 7200rpm and the launch control at 7500 and with the 90 fuel enrichment and -20 on the timing.. it went to around 10-12 psi..
that will work!
thanks

Mine is setup for a 7000rpm rev limiter untill 10mph. with no added timing. There is no reason for me to build any type of extra boost. I have a serious traction problem as it is. At least at the import face off I spun untill 3rd (smoke pouring off the tires) then when I would finally hook I pressed the button and hit high boost.

What size slicks are you running???

Your setup is almost like my setup, same turbo, gas, and power. Nice numbers by the way. I'm trying to hit 10's with this turbo. What size a/r is your exhaust housing on your s366??

On my 372 setup, it was about 400-500 fuel enrichment also.

And about 25 pounds outta the hole

It was at import face off in columbus. they are Beat M&H 24.5X8.5X13. Its a T4-366XL I think its the .83 housing!

Thanks goodluck your going to have traction problems

Do you mean 9's??? 10's with that power isent going to be a problem.
One pass I spun 1-2 then I hooked in 3rd untill the 1/8 let off it still went 10.8@114.
