Can someone school me in ECU's and Hondata?
I dont wanna put my flame suit on and all but i kinda need a lesson on how ECU's can make your car run faster and what exactly is Hondata. Im a newb to this whole techincal part of cars. I get everything else except for these parts. I would be grateful for any kind of help, i would search it up, but i thought it would be better if i had first hand information from experienced ppl.

ecu's are basically the brain of your honda. without the ecu, the car will not run. you probably know this. when it comes to ecu reprogramming or 'chipping', certain aspects come into play with how a motor is setup, such as: being naturally aspirated, turbo charged, NOS'd, or supercharged. All of which can benefit from an ecu 'chipping', depending on the type of program that is used.
A rule of thumb is, if your engine is basically stock (no internal engine work), there's no need to reprogram your ecu. The factory programming is near perfect to the respective motor & ecu. But when you get into internal engine work/upgrading, camshafts mainly, this is when you really want to get an 'ecu upgrade' or 'chipping'.
Another rule of thumb is, when upgrading your camshafts (depending on what cams you get) an ecu upgrade should follow, because cams & ecu reprogramming go hand-in-hand. Follwing this would be getting a set of cam sprockets and fuel/VTEC controller, then visiting the dyno to fine tune your engine/ecu/and VTEC controller, all at once to extract the most power and to see where your powerband dies off at. Some big spec cams such as Toda Spec b/or Skunk2 stage 2 cams (or higher) need the compression ratio raised in order to make their optimal power too, but thats getting off subject.
Upgrading your camshafts increases power output and torque to a certain extent. They also raise your powerband (making power beyond your stock engines redline). So, to take advantage of this, an ecu upgrade is needed to raise the redline (revlimiter) point since new power is being made beyond the stock redline point. Also, if we were talking about VTEC cams, we'd want to adjust the VTEC crossover point accordingly too (raising it).
An aftermarket program that your ecu runs off can be modified from mild to wild, as in modifying the curves of timing, how much fuel is being dumped into the engine, disabling certain sensors and speedlimiters, and customizing VTEC + redline points to make your engine happy.
Each department of engine upgrading, whether it be turbo, NOS, NA, or SC, needs their own type programming so the ecu can satisify the engines hunger for air & fuel mixture & timing. They all differ too, so you need to know what type of engine scenerio you would like to ultimitely go with.
Hondata is just one of the many ecu tuner's out there, just like I am (see signature). They're well known because of the advances in ecu tuning they've made over the years. They also have a line up of interesting products; stand alone ecu systems, I/M gaskets, etc.
There's a gang-load of more info on ecu tuning out there, this is just an insight of what ecu tuning is about. hth.
