Well I recently stumbled onto something I didn't even realize was out there. Launch Control???? Well I am pretty much a noob when it comes to this stuff, but don't hate just appreciate. I searched, but must not be searching in the right place and maybe this was touched already. Anyways what do I need to do this? Where can I get it or where do they sell something like this? Anyways your input would be greatly appreciated. Thanks.

 

a launch control can be set onto a burned chip for your stock P28 or something.

Basically its a rev limiter that the computer enables when the comp. reads 0 mph from the vss.

phearable or somethin like that makes decent chips.

But if you got hondata or something better than a stock ecu then you should know that the feature you want already comes with it.

 

you can also utilize an msd system to do this. u need an msd ignition box (6al), a 2 step , you can wire it to a button or switch. you also have to wire your ignition to use an external coil. very easy to do but will cost you some $.

 

Is the Msd cheaper than the chipped ecu? I am going turbo and was planning on getting the Msd 6al or btm anyways. Thanks very much.

 

if you plan on going turbo you are going to want a good ignition system as well as a good management system.

 

yeah i def. wouldnt make a decision between a chipped ecu OR msd. if you were thinking of getting msd i would go with a digital6/7 (already has alot of good features built in) and then get a good management. dont cut corners or you might wanna cut your wrists when your car blows up.

Not everyone is running as much power as you Tommy! lol

the stock honda ignition system is fine up to about 450hp.

i got the power thing down now if i could just learn to drive it

The stock ignition system is good for way more than that if in good condition.

 

one thing i have noticed with software launch control vs. the msd is that the stutter between firing is faster with an msd setup than it is using software alone. the MSD setup seems to be able to control the frequency of the cut much finer than the software can.

another variable that affects how fast the ignition cuts is the rpm setting of launch control. for my car, the setting is at 4k, so i may be seeing it as a slow cut, but its really because my rpms are not that high to start with.

I run TurboEdit software launch control in my daily driver, and the frequency of cut seems to be at about 4hz, where the msd boxes seem to cut at atleast 8hz or so. every once in a while i will get a delayed launch because the light turns green and launch control is busy cutting instead of letting me go. Its not a big deal because it is my daily, but if i got serious i definitely would like it to cut at a higher frequency, which means i would go with the msd box, despite probably not needing it to handle the ignition of my 140hp daily.

sorry for the long drawn out post, but i think if i had to do it again, i would go with the msd to start with, even though i dont need it, if the main purpose is for launch control. Software definitely is the cheap and easy way to do it, but from my observation, (turboedit anyway) is less ideal than an msd setup if you are serious about effective launch control.

that said, it is still fun to surprise people in my daily.

 

With launch control from the MSD box, do you have the option to turn it on and off?

I have launch control on my Uberdata ECU and it stutters slow between fire also, but Im launching at 4000, so thats probably most of the cause of it. I already got a BlasterII coil, but no ignition box, I would like to install one IF you are able to turn the launch control on and off.

 

you can wire the 2 step to a button,the e brake the clutch switch,there are many ways to turn it on and off.

anti lag is cooler

Thats why I have to wear ear muffs at the starting line when we launch our crx!! lol

 

here's my setup and what i do:

1st i've never ran crome's (or anyone elses software rev limit) because cutting fuel is most def. causing a lean condition while thats happening.

I DID, run a msd softouch rev control (forsale btw) with a 2step selector switch and the rpm pills needed.

when the button i ran to my steering wheel is pushed, i have a 6500 rev limit(for launching) once the button is let go, it defaults back my other RPM pill (9800)

NOW- i decided to run a MSD digital6+, which is a ignition, 2 step and rev limit all in 1 box, i needed the room so i removed all the individual boxes in favor of this one.


check my post out on how the boxes wire up, there was no info to be found on this, so i created a post about it.

FWIW, the fuel cut used in any ecu for a rev limit, be it honda's ecu, AEM, Motec, etc will NOT cause engine damage. It does not cut the injector off in the middle of an engine cycle, it cuts the injectors in a pre determined sequence for an entire engine cycle. No fuel for an engine cycle means no fire, no lean condition.

You really think Honda would make a rev limiter that would damage the engine?

even a good driver cant do crap with oil on the front tire.

 

Anybody know where I can get all this stuff? Ebay? So far I have a huge section in my room full of parts and pretty much I am planning on buying everything and then all at once. Thanks.

 

ebay son i put digital 6's on everything i drive
