Usually when people say "2 step" they mean launch control.
You can use a launch control in various softwares such as Hondata, Neptune, eCtune & crome.

Hondata pricing varies on which system you buy. For more information on hondata products check out hondata.com

 

is crome n neptune like chips that u add to ur uce obd1 or 2? or is it the whole ecu?

 

Crome has a free Version that is run by burning chips. Never used crome pro so not sure about that. For Neptune it comes as a RTP board. It is installed to where the chip would be located.

so i just get obd1 and chip it will be cheaper then getting a whole hondata unit?

 

The Hondata is a chipped OBD1 ECU with their unit plugged into it. Just like the Neptune Demon and eCtune Demon are also chipped OBD1 ECUs with their units plugged in. They are all real time programmable (RTP).

If your not going to be tuning your car yourself and you are going to have it tuned. You would be better off contacting your tuner and asking them what software they use before you go spending your money on hardware & software. Also probably be a good idea to ask them if they chip ECUs, and if so, how much they charge. Then you can shop around. You may be able to get one online cheaper and bring it with you.

 

What is this? Just a lower RPM rev-limiter that kicks in when the car is moving below a certain speed (MPH) and throttle % is high?

 

Pretty much!

It's for keeping your rpms up to a certain level so when you launch off the line the rpms will drop into your target rpm/power range for an optimum launch traction. Not exactly a street application, The cops tend to pull people over if they use it on the streets.
