I dont get how uberdata works...can someone just explain how you make this thing work. i mean everyone says go with it, but i dont know what it is. i am sure that this has been brought up a thousand times, but can someone just answer this for me?

stock ECU was not made to read boost so when you go pass 0 vacuume, it will only dump that much fuel no matter how much more you boost it. for example the ecu will dump 100 unit of fuel at full thottle (0 vacume), now your motor us seeing 5psi postive pressure(boost) which requirded a lot more fuel to ran it safe, however you ecu will still dump that 100 unit only.
so you chip your ECU to work with a Programmable chip.
you burn the correct program into the chip, now the ECU is capable to read boost and adjust the amount of fuel/timing according to level of vacuume and boost.

also, oem ecu will only allow stock sized injectors.
now let me make something up to help u understand:
say stock injector will dump 50 unit fuel at 1000 rpm by opening the injectors at 0.1 second at TDC, now with you 450cc (or whatever it is) your ecu is dumping WAY too much fuel because it is being open at the same speed (0.1 second) as when it has smaller injectors.which cause it to run too rich = won`t work
the 450s could have doen the same thing by being open 0.05 seconds
(i made all these ---- up don`t flame me :P)


now you got what you want and i wrote what i know. i am looking for a equal length manifold as my birthday present.

its basically the cheap but effective(so I heard)way of having a stand alone.some one chips you ecu down loads a base map for it then you get it plug it up to a lap top and you can control your timing ,air fuel ratio,etc.the only thing you need 450cc..this would do what the afc or fmu btm would do all together.

what donald said

but will someone else, like at a tuner shop, do it for me? or do i do it myself. i already know what the program does, i just want to know how you install it. do i or tuner shop?

DeleriouS

So does anyone know this? Becuase I am not undestanding how this uberdata works....because if it is the cheapest and most effective, i would love to use it

i know someone that ran 10lbs of boost on a t25 and only ways of tuning were a pr4,fuel pressure regulator,and retarded timing. the setup went a 13.2 and lasted a year but i still highly recommend some type of ecu program.

DeleriouS

i have no idea what you are talking about...lol
