What does this do?

my goal at the moment is to find out what this little thing does, any help ?

I cant make out the working (small stuff). Wierd it will be an aftermarket computer of some sort but for what I have no idea. Where is it located ?

razor , its is a aftermarket comp , i have the original one in a box , its located in the pasenger foot well .

as for the wording " its great ".


The tachometer climbs rapidly up the scale and suddenly you feel it , and you hear it.The sound is almost imperceptible- the high pitched whine of a turbocharger. The feeling is more apparent- you're pushed back in the seat . The world begins going by very quickly.
You feather the throttle and down-shift, snapping the lever of a 5 speed overdrive transmission through its short throws. Ahead , the road bends out of sight. With a light touch on the steering wheel you command the car and it obeys- power rack and pinnion steering precisley following your directions. The 4-wheel independent suspension yeilds just enough as the tyres grip and you're through the apex setting up for the next corner.


CENTRAL 20 racing team.

It is merely an aftermarket ECU. Since the R33 ECU'S can't be chipped the wonderful tuners of Japan have decided to make their own. It sounds as though they have played with the shifting control of the autobox. That too is common.

As far as tunability it is anyone's guess unless you take your car to someone who can get it hooked up to a laptop and even then it may be all in japanese.

autobox ???

Correct me if I am wrong but the R33 GTS25t had a 5 speed automatic and a 5 speed manual. From your statement it appeared you had an auto "autobox". If not then that part of my statement is inncorrect. If what you are saying is true however your car must be pushing, as it would see, 500+hp as 5th gear in a manual car just doesn't pull what so ever. The acceleration rate is groggy until you reach quite a bit of power. I know because when I was at @ 400hp in the GTR 5th just didn't pull for shyt, while it does now :)

Central 20 ECU, supposedly they run real rich mixtures and theres basically no one who tunes em outside japan.

thank you phatdex

so no one knows for sure?

Auto controller in 25t's is in the drivers side kick well..... exactly opposite to the main ECU. Don't think the R33's had a 5 speed auto either.....

you can see it says in big letters "BRAIN" on it , hmm maybe its the cars brain = computer/ecu

no shit sherlock
