ECU Tuning & Fuel Management - How many of u heard of this?

hey, whats up guys, one of my friends was giving me the grande tour of his 97 civic ex, no swap, just stock d16y8, and well, he showed me something id never seen before, but dreamt of a few times lol, but i forget what its called. (its for launches) Its a little switch that is hooked up to ure ecu. You put the clutch in all the way, and flip it and hold the gas down all the way, but the rpms run evenly at 3500 (for the good launch) and u just take ure foot of the clutch to go. Perfect start everytime. Can u guys tell me what its called? i forget. It is a modified program on the stock ecu. his brother does all of that ecu stuff with the engine maps. thanks guys

launch control.

perfect thanks, now one more question... any downsides to it?

its hard on everything on the car. and its way more useful with a turbo car. it lets the turbo spool up to almost maximum torque, then its all there when you drop the pedal. then its just about the traction.

Yeah I saw somithing like that at advance auto, changes your idle>>

you can get the s200 (hondata piggyback) it has a 3step rev limiter and u can set it with that.
