Default Launching devices?

Hi guys, Im new to honda-tech and all...I wanted to know what everyones using for a launching device (rev limter) at the starting line...I want to have a set up where I have the clutch pedal depressed..it only goes to about 4 grand to launch. Cutting only spark, not fuel. Then when the clutch is released I want it to rev to red line or where ever the limiter takes it to...Does this make sense to anyone?? I heard Z10 motorsports is the only place that makes one with a clutch switch...Any help would be awesome!! Is this what causes the cracking and banggin at the line?

Get a Haltec. Has a built in rev limiter.

What a great answer... Jesus

All you're looking for is a 2-step. As 91civicDXdude said, you can use something as simple as an MSD box. There are a few ways within, some boxes are nicer and have more features than others, but what they all boil down to, is when you apply a 12V+ (some use a negative trigger) to the 2-step line, it is active. That allows you to tap into your clutch switch, or whatever you'd like, using a relay if the circuit must be reversed.

Some of the higher end engine management systems (Motec, etc., and even the new Hondata) do have built in 2-step control, but it sounds like that's way more than you're looking for right now... You get a lot more of the "bangin' and popping" with anti-lag on the turbo cars!

Thanks kataku2k3...I considered the MSD 2 stage for now...But don't you have to already have the MSD box like the 6 or 7 series? I want to try to say away from doing that because the stock honda ignition is a good system or so I hear??..Or can I just install a 2 stage without an additional MSD box?? Thanks again

What kind of slicks are you running? It's pointless if your not on slicks. Also reving to just 4k and then to redline when the clutch is out will only make your car bog on slicks or burnout on street tires/drag radials. It kinda sounds like you just want to look cool off the line with the "cracking and banging"...

stock honda ignitions are awesome, but if you need a 2 step msd is the way to go.
i have a msd digital 6 i got at the end of last season, wanted to try the 2 step. seems like im better off without it, only used it for 2 races now selling, let me know!

msd makes a 2-step box that is a standalone and does not need an msd ignition box.

i thought the 2 step box was just the dual rpm pill selector that is still used with msd boxes

Most aftermarket EMS have built in two steps. You can then wire that up to wherever you want. Clutch, ebrake, switch. I am located in macungie. Right next to you. Shoot me a pm if you need help.

It wasn't a useless post. This guy obviously doesn't know what he is doing. I would suggest practicing your launches rather than spending money on a 2-step, which might not even be needed from the sound of it. As I said before it's really pointless unless you at the track on slicks.

hondata or the neptune rtp vaporware should do the trick with stock driveability. Probably not too much more than the msd setup and far more capable

We've used just about all of the MSD boxes in the past and I don't really know what the difference in the way the 2-step is firing the ignition, but the MSD HVC box pops like crazy (on a turbo motor), and builds a bit more boost (more retard?) than the MSD Digi 6/7. This really won't apply to you, so don't worry. Just tossing a little more info out. The Digi boxes are awesome as you don't have to deal with pills, but you're limited to 9,900rpm unless you've got an EMS that's capable of killing the spark (or fuel, not that we ever do so). Again, most people don't worry about this, but we've had to rev a couple motors higher than this in the past, in order to not run out of gear...

Off topic: Stock Honda ignitions aren't great, but they'll go a decent ways... Individual coil + hall sensor + a good EMS is the way to go!

i do it speed based with aem ems.. under 10mph the 2step is active, once you go over 10mph it switches to the normal revlimit

How much boost can typically be built off the line from the MSD Digital boxes with that second rev limit set up for lauching?

TRUE! you honestly dont need it unless you've got traction issues getting off the line..Dont listen to people telling you its the greatest thing in the world yada yada yada and you should run out and buy one asap..hey dont get me wrong it is great and i did use it..i dont believe in buying things unless its absolutely necessary cause it just complicates your set up further and adds another hole for something to fail ex. Ignition coil, Cap, rotor etc.. Practice your launches..trust me they will get better with more practice..and if you still feel the need for a launch control do to tractions issues..by all means go for it!

Wait..are you N/A or Turbo?

You can get up to full boost off the launch if im not corrected.

Ok...The main reason I want to try a 2 step is becuase every time I want to race my car...I can't get a consistant launch NEVER!!!...My reaction times are different every time!! Never the same! I thought that maybe a 2 step device would aid me and getting a consistant time..But I don't know why everyones got to say something rude or very unusefull...but some of you guys are a big help..and I thank yous all...And my hatch is a bulit ls/vtec runnin a B16 Trans w/LSD

If you want a 2-step/launch control device, just get one... You don't have to listen to everyone else.

And as for how much boost you can build with just an MSD 2-step, NO where close to full boost (if you're talking a standard high hp SFWD car that runs 30lbs). We typically see a couple pounds, but as soon as the motor is loaded, the boost shoots right up. If you're looking for more than that, as I said before, get a good EMS with a lot more 2-step control (antilag/boost overrun).
