Launch Control

[CRXer]

ok...let me ask...if comparing 18 degree and 30 degree, will it gonna change 0.5 sec of your time???

ask jdmyard who are playing with hundreds even thousands of a second atm.

also add track temp,tyre temp,rubber down,humidity....list goes on,ive never seen a datalogger in our end of the market thats gonna determine anything like thies for u.

launch ctrl that offers ground speed detection will help to give an est of "more or less wheel spin" while u launch the car...so track temp will not have too much to concern if the file created is perfect...

speed detection coupled with rpm is only gonna give u a look at what went wrong for how long,not tell u exactly where the track is at for any given run

and exactly which ECU are you running may i ask since i can assume that you have quite abit of knowledge about LC...

s300

[todaek9]

ohh...heard many good stuff bout the S300...
how many sensors did you run on the car with LC setup??...

all sensors are datalogged at all times,the only thing involved with the LC is simply a clutch switch.

This thread makes my head hurt now.

toda - just listen to what CRXer is saying...

If you are serious you will adjust the setup at the track to suit the conditions.

The answer is no
From What We experienced , temperature difference will not change your ET by 0.5 sec. But again this is depending on how consistence you are .

[grumpy rooster]

Just to clarify, that difference in temperature won't affect your times that much if your talking about the difference in power. But if you are talking about how the track will affect the times from these temperatures then yes, it does make a difference but more like 2-3/10ths of a sec.

When you get really cold conditions the track cools down a LOT and then becomes very slippery. Your 60ft times will increase which in turn increases your ET. This is what happened at Compak Attak, so much so that they cancelled the remaining part of the event because the track cooled down so much that it was like an ice rink for the more powerful cars.

Essentially what the guys are saying is that there is no "one setup fits all conditions". You may have a good base setup that is fairly good for most situations but to optimise your ET's on a given day there will always be some adjustments to be made. Ask Yonas how many different tyre pressure and rpm settings on the launch control he may try at any one street meet. The only way to find out what works is to try things. Launch control settings and different methods of launch control is just one part of it.

Drag racing is not as easy as a lot of people make it out to be, especially in a FWD.

get a bee R rev limiter LC system, as it can be adjusted anytime,

Having used and tried to setup LC/two-step myself (Haltech ECU).

I found manual launches gave quicker ETs.
Got a quicker reaction time with LC and pretty flames but that's about it.

It might be a personal thing or maybe more suited to cars with high HP or AWD. Where clutch and throttle aren't too important.
Dial in the RPMs, side step clutch, bury pedal into floor and hold on.

Shooting 1m flames is hella worth it, just for launch control
