Yes yes... How can I disable the speed limiter in my A31 Ceffy, hits 170 and then bam.

Cheers...

The only way that Ive heard of is by getting the computer looked at or even chipped by a proper car tuning place. Over here in NZ a good place is NZEFI, if you look them up you might recognise a similar place in Oz? But there might be other ways too

Not sure with the A31's.. I know with the A32's its just a matter of snipping a particular wire on the ECU wiring loom. Might be as easy as that if you look around. You'll probably find it'll be the same as a skyline R32?

The snip of the wire is the same with the Z31 Turbo ECU's which I have... I dont know anything about Cefiro's really, I only owned it for about 2 weeks now lol..

to be honest i would look up the wiring diagram and try find the wire what cuts the fuel of.

its the pink and blue one on the A32.

if u cut the wrong wire you can just join it up again. i had a mate who cut and re joined every wire will he found it lmao

it must be a japanese A31 Not made in aussie, with this fairly the aussie A32's mmust not have them any one willing to try it out?

Yeah its a jap car... everything is written in Japanese. Dont know if you can find manuals for the car, I dont even know where the ECU is located. lol...

Yea Timmy is probably right, Ive seen a wiring diagram somewhere on the net. ECU is on the passensger side, in the foot well, but on the very left hand side of the car.



Yes im very bored lol

Knew it was somewhere, thanks D1nz.co.nz

(There should be 4 big blocks going into the ECU, the numbers above correspond to each wire going into the back of the ECU)

So Going by that you'd have to cut number 53? Hope it makes sense lol

Ah sweet... cheers Sam.

ECU is located the same spot as my Z31 was...

Now I just gotta get off my lazy ass.

this is going in the stickies...

No worries, Yay I made a sticky lol, I feel so important

lol.. the first and only sticky

so cut 53 and my a31 has no speed limiter?

yeah cut 53 and you have no speed limiter. worked in my a31 and mr r33.
