Does it have its own programming language of sorts, and hence would need some coding skills to configure properly?

Lastly...meron bang parang ECU simulation software out there? curious lang kasi ako kung ano ba talaga itsura niya B)

heres some quick info:

-stock ECU's are already pre-programmed from the factory, but it can be "hacked" or re-programmed by sending it out to a Authorized ECU re-programmer (ECU flashing.. like Hondata, WORKS, Turbo XS, etc..).

Or you can install a Piggyback ECU or a Air/Fuel controller (Apex-i SAFC I & II, AFC Neo, HKS VPC, MAP ECU, etc...) in which you can tap the them in-line with the stock ECU (tap them, meaning wiring them up in the same wiring harness of the stock ECU).

you can also buy a re-programmed ECU chip and install it on the stock ECU, but its not fully controllable since that its already pre-programmed.

-also there are the ones that is called a Stand-Alone engine control units. these are the ones that you may have seen on the "F&F" movies. the Stand-Alone ECU is a fully programmable and adjustable ECU, which also replaces the stock ECU. meaning, hindi mo na kailangan ang stock ECU.. since the Stand-alone EMS will replace the existing ECU and wiring harness from your car. (so basically, if you use a Stand alone ECU, you'll have to re-wire your engine wiring harness. and you have to use special sensors (the ones that is made or is compatible with a specific Stand alone ECU) but some stand alone's can use the stock engine sensors (TPS, Cam sensor, Knock sensor, IACV sensor.. etc..)

also, the only way to control a Stand Alone ECU is by using a Lap-Top computer and you have to tune it at a Dyno (or even on a empty road. we call it "Street Tune"..) and you need to have a Wideband 02 sensor and a Data Logger to read and measure your engines AFR's (Air / Fuel mixture readings).

then once you have the lap-top connected to the stand-alone ECU then you can now see the graph/values/tables for each engine RPM's, Timing, Knock, Fuel pressure, Injector pulse rate, AFR readings, Manifold temp & pressure.. etc.. then you adjust everything accordingly (through getting the right AFR's, timing, idle speed, knock suppression, boost settings, traction control, etc.).

so basically you tune everything on the engine (and have complete control in engine tuning) by using a Stand Alone ECU.

and heres some examples of a Stand-Alone ECU:

-Motec
-AEM EMS
-Autronic
-Haltech
-ACCELL
-Megasquirt
-HKS F-Con
-Apex-i Power FC
-Greddy E-manage

and some that I could not remember! but yes, those are probably one good examples of a fully programmable Stand Alone ECU.


aite, peace.


note: wag maniwala sa lahat ng sinasabi nila sa F&F!! specially on the first movie!! "Motec exhaust"??? WTF??? theres no such thing as a "Motec exhaust"!!

also, speciall effects lang yung mga "overload".. nitrous level.. etc.. man, that is plain Hollywood crap!
