limiter removal

[elftron_2004]

i was wondering how do u remove the limiter in a u13 sss without stuffing the dash, ppl talk about ways to do it, then someone esle does it and screws up all their dash instruments... has anyone successfully done it without stuffing anything up..... cheers

Limiter?

What limiter?

[elftron_2004]

oh sorry, the speed limiter, its set to like 180kph, wouldnt touch the rev limiter, never gets there anyways

[wombat]

judging by the modifications that you've already done, my advice is - Don't. It is obviously not a racing setup - you've got a stereo and no rollcage. If you're going anything over the speed limit, it's against the law. 180 on public roads is stupid and dangerous enough.

i do the eastern creek wednesday night fun sessions with a couple of mates... not all the time, been 3 times in the last 6 months but want to get back there, rollcages arent essential, but gotta have 5 point harness + neck support and racing suit, its not essential for me to do it but its embarrasing toping out at 180 on the straight

i would never..... ever.... ever.... attempt 180+ on a highway, ive lost too many mates to that shit...

[noss]

its a setting on the ecu, it has nothing to do with the dash.

also i didnt think the aussie u12's had a speed limiter anyway, only the japanese ones? or is yours an import?


either way, a daughterboard and some chips or a nistune board and someone that knows how to tune will be able to remove the limiter.

I didn't know aussie U13's had a 180kmph limiter, but good to hear your taking it to the track mate.

[elftron_2004]

well i feel at home in my bluey, its my cup of tea, i had a factory manual vk v6 which was good...ish... excellent condition with the brockey kit which i used to take there a bit, in the end it was too unrealiable to do it, its not about the times to me, more to sedate my driving around the streets, unleash on the track, cruze on the streets!!!

[elftron_2004]

and yer for some reason its limited to 180kph... its definately aussie spec... not imported but there were receipts for ecu repairs a few years back...

i can tell you that the Aussie U13 doesn't have any kind of speed limiter built into it.
You might might to check out what ecu repairs were done.
And Do a ECU reset, could help.


Also while theres talk about limits what exactly is the RPM redline ? And the cut off ?

i can tell you that the Aussie U13 doesn't have any kind of speed limiter built into it.

Correct!
Certianly not on the 93/94 models anyway.....

if it's anything like the skyline speed limiters just cut one wire and ding

[Leopard-Man]

nah there is no way the aus delivered u13 has a speed limiter.  nope no way doesnt exist.  full stop.

[wombat]

Does it shut off or just not rev any more?

I don't know about U13's, but AU Falcon limiter goes like this. 178,179,180 - Fuel injectors cut back to idle, transmission disengages, and everything spins back up at 175.

If you're just not pulling any more, that suggests that you're probably going as hard as it can.

[elftron_2004]

problem solved..... some dodgy bastard mocked up a ecu from a 300zx and chucked it in there..... it was done actually smartly as it was all soldered good, molex plug adaptors, terminals were sheaved, etc... i ended up going to pick and palyess and picked up the ecu i should have and it cost me 10 bucks plus swapping the other one.... it goes better now!!!!

[Budgie]

What!!?

Your U13 was running a 300ZX ECU??

[cruizer]

How could you tell it was a 300ZX ecu? Something smells fishy and it ain't the antrx.com post whore, Bill...

[Jason]

What the hell is going on?? Dude, put up some pics of what happened and try and write up an explination to whats going on here.

[snailman]

What!!?

Your U13 was running a 300ZX ECU??

possible!? wtf...

[BILL*69]

Something smells fishy and it ain't the antrx.com post whore, Bill...

Too right, im a chicken man!

[Vithy]

WOW
now thats wat i call a bomb shell :S
u13 running 300zx ecu :O

[elftron_2004]

well yer.... i would of taken photos if it was any interest.... the wrecker seemed to be admiant that i had been sold a dud car, a "cut job" but it doesnt have weld marks and doesnt crab walk or anything, the chip was missing some "Mosphets" (the spot had been soldered up) or something around and a few new wires had been run to MAF and other stuff?? im guessing air flow..... im a noob to this so got a second opinion and they said it was too dodgy to keep, would have been good if it was done right.... but the car is way better with the new chip.... its lost a mean as lag at ~2600 rpm, replaced with a slighter one at ~2200 rpm

if its any consellation, the case it was in wasnt square, wierdly shaped....

[elftron_2004]

so thinking about it.... could it have done damage to my car.... its sounds like someones dodgy dealings to use cheaper parts or something.... what should i be checking to make sure its all in good shape.... im freakin now... i cant afford a new engine!!!! on the outside it looked like it was sposed to be there, like holes for plugs, stickers, mounted flush.....

[slim]

Did you check all the VIN and engine numbers and im not sure of what your state offerers

If you can post some quality photos or have a look at other U13s and try and look for a difference in appearance of body panels, their fit, the seals and gaps.
If you have the pdf that has the U13 info it, theres a link on antrx for it somewhere ( PM me and ill send you the chapter). Then in the " Body And Trim" section theres an alignment diagram. that will help to see if the cars been 1/2 and re-welded.

cheers mate, i know it has had been resprayed, colours match well, jst has more "orange peel" in places, the bumpers are a bit out but i have had most of the interior out and nothing caught my eye..... and also had  a revs check done at the time ( my mate at the time bought a stolen car, wasnt going to risk it, even tho its from a dealer)..... but if u had those specs that would be good, then i can find out why..
