Hi,

I have read about some of you having a launch control system installed.
I would like to have launch control system, especially for use on the tracks.

I am running a B16B Type R Engine in my EG6 on the original OBD2B none chipped ecu.

I own a OBD1 none chipped ecu, a Crane Hi-6 ignition box, and PS92 Coil.
I havent use them yet, but would like to know if these thing are usefull in order to have launch control installed on my civic.

Can someone tell me, what exactly I need, and where to get it from?

dear friend... in my opinion launch control is useless just for show... if am not mistaken u need a new ecu!! i personally have a launch control its a program on my aem black version ecu but i just use it for show just to throw some bangs and fire from the exhaust nothing more
 
I certainly wouldn't say it is JUST for show....just maybe not necessary on a standard b16.

A lad at work has a 425bhp corrado, with race logic traction + launch control and that was putting down consistent quarter mile runs of 13.2 at bruntingthorpe, so not even a proper track. He absolutely destroyed a lad in a MK3 golf, who had a similar power but no launch control....it really is worth it on the right car.
 
cheapest way to get launch control is find a p28/p30 ecu. get it chipped and run a base map for your engine with crome. you can add launch control at the same time.
cost me 35 quid to get my ecu done. i only got launch control added to see what it was like.
as for being useless i couldn't disagree more, a mate of mine ran it on his 411 bhp b18c4 turbo eg and it sounded awesome. got his times down on the 1/4 mile by a fair bit too

Is a OBD1 ecu related to a p28/p30 ecu?
I know a OBD1 ecu can be chipped. I have a OBD1 ecu, my question is, can i use it.

I want launch control, not for extra horse power.
Simple to start from 0 always at 5000RMP without delay.

if your ecu says p28 or p30 on the side then yes you can use it

I have my ecu here in my hand, it has some numbers under the bar code on the side: 37820-P30-010

i see i can use it P30 is there.

Now, what else i need? get it chipped, and????
 
does the omex rev limiter work?

just want to throw out some bangs :D
 
launch control. Pah. do you want abs and traction control too???

man up.

jeez.
 
At the drag strip, when the other driver reaches the line before you and stand in place, he can easely have time to balance his rpm at the desire hight.

It will be easy if you have launch control installed, and you simply hit the gas, and our rmp will lock at the programmed hight without delay at start

you'll need to get it socketed so it can be chipped. there's a site called h-tune, he did mine on my ek9 and launch control can be installed with your base map

Problem with set limiter launch control is the rpm it's set at might not suit the surface at different drag tracks. You could end up bogging or spinning loads depending on tyres, track surface and weather conditions on the day. You can have it tps based where you can set it where you want by applying lite throttle to reach desired rpm then floor it to hold at that rpm but not all obd1 tuning software supports this and it's not always successful.

I set up tps based launch control on a eg6 rally car a few months back and after a few rallies the driver asked me to disable it as he wasn't finding it very usefull and has since reported better launching off the line without it so I think that says it all.

I think launch control best serves it's purpose on a boosted car coupled with anti-lag so you can build boost at the line before launching.

Best form of launch control is too smash the limiter untill the lights go green.

thats pretty much the set-up my mate had on his boosted eg. works even better if you have boost by gear set-up as well

I understood you, so only thing I need instead of a launch control is practice!


But at the drag strip, its not the faster car that takes the first place.
The magic is to do 2 qualify runs. You will have to try the best you can.
And for the rest of the race, you should hold the same time!

I made 1st run 15.71 on 1/4mile second run 15.77sec

So you need to give a dail-in number. I give 15.70 as dail-in.

My third run I ran 16.13sec and got eliminated by the other driver who had a 17.60 dail in, and ran 17.88

he had .28 delay, i had .43

My reaction time in all 3 race was around 0.3x

My mistake in the 3th run was that at start, I reached second at starting lights. As soon the 2 lights came on the other driver lights start counting.
I was nervous! I pushed the gas in, rpm went to around 6300, I release the gas and rpm went to around 3500. Meanwhile the other driver left, and I had to go 1.9 seconds after him.
because of the tention, I could not hold the gas stable to get a 5000 rpm like I did in the 2 qualify runs. So I had a bad launch which made me make 16.1sec

I thought, having a launch control will help any driver, at the start line of a drag strip, you just push the gas all the way down, and the RPM will not exceed the starting limit. In my case I would like to have it for 5000 rmp.

So this made me think about using launch control a 2-step or something similar. But I am not sure what I need.

I think with launching its trial and error as to what works best. On a boosted fwd say you may feather the throttle upon launching in a bid to control wheel spin obviously foot control is key here. unless you know the drag strip the first few launches probably won't be spectacular anyway as you won't know how your tyres are going to hook up with the surface there so yes practise will be key:nice:

I will practice. It was my first experience at the drag strip.
The drag strip is good, it has traction if the name is correct. So the tire stick to the ground.

When I launch at 5000 RMP, you hear spinning for a 0.5 second, I right away get full grip.
I am runing a B16B Type Rx '00 engine with Password JDM Dry Carbon Fiber Power Chamber with a J's Racing Air Filter. Thats my only mod I think.
I am planning for a 3" alu intake pipe, and make it long to reach into my front bumper with a apexi 75mm filter. I had it like that 1 year back, but sold it. I feel better trottle response with the apexi filter comparing to the J's racing filter.

I think I can do a better time, I had 16" wheels from a friend who wanted to borrow my 15" ENKEI racing wheels, so he could race. But he did not reach on time. So I was there and did subscribe my car for racing. Running with a 18mm multiplex in the trunk with a 10" subwoofer heavy like hell, a 2000 Watt Amplifier a 2K Capasitor and 2 6x9 3 way speaker. All this around 30kg. I have to remove them when racing.

The 25th of this month I will be on the drag strip again. I will see if someone will film me on the event while racing and I will load it here
