No Limit And Wierd Noise.

[oncheap]

ok, so my car officially has no rev limiter, it goes all the way just past 8 grand (before i back off cos im scared she'll blow!). im 99% certain the taco is accurate as i hooked up a SnapOn diagnostic comp and it read the same. also went for a drive sunday and there doesn't appear to be a speed limiter. just wonderin if anyone has experianced this and they know why.

second thing, little while back went for a massive 1 and a half hour drive about an 1hr of hard driving and now im gettin a metal on metal sound like a scrap, periodically. sounds like its coming from the front left hand wheel. Possible break issue? i haven't experianced any lack of performance in any area since the noise started. so i got clues. any help would be great guys.

My Old R33 had a HKS F con V Pro piggy back type ECU. At one stage I removed the F Con and just ran off what I thought was a factory ECU. Anyway it turned out that that ECU had no rev limiter or speed cut either and had obviously been modifed. I'm guessing yours had been modified the same for what ever reasons.

The metal on metal noise could be brakes, could be faulty shock absorber, could be your rim scrubbing on your coil over etc ... could be anything reall.y best thing to do would pull your wheel off and check for scrape marks as metal tends to leave an obvious mark.

I know my car has no Speed cut but dam, That would be scary unless you have a RB24 then it might be up near the 9's

ps dont do burnouts or drift

You wonder what the last owner has been doing with your car when you get it with no rev limiter or speed cut. If you can get your hands on a standard computer hook that up and test it out.

metal on metal.. does it sound like its coming from the turbo? it could be on its way out

otherwise i have no idea

[ross80]

the metal on metal sound is you running into the guard rails because you cant handle the extra rpm and speed.

Get a clue!

hhahah

gee thanks for that i'll keep it in mind..... yeah i was thinkin maybe the turbo as well, cos when i hooked up the manual boost controller to the actuater line there was a bit of oil run. now as far as i know with my limited knowledge, having oil in the turbo might not be best sign of a healthy turbo. But then again as i said before, haven't lost any boost what so eva, gonna get the brakes done early next week and see what happens. also yeah checked the ECU its factory doesn't look like its been modified at all, is there anythin to look for?

otherwise cheers at least i know im not alone.

The actuator line is a vacuum line, if you have a heap oil in your vaccum lines its usually a sign of blow-by. They don't always mark the ECU's when they modify them.

could be a dust cover around the disk break. you might have even warped a rotor..

i had a similer sound coming from my 32 a while ago, turned out to be a very thing peice of metal on my brake pads that gently rubs on the discs basiclly lets u kno ur pads are getting low. they call em squiller pads or sumthing.

an concerning ur ecu they may have just cut the wires, i kno The wire is yellow/green with a silver trace is the speed limiter. check this website out an read a few things on there u may be able to locate the problem.

Sounds like your brakes are prolly just getting low after the thrash. If you look thru the wheel you should be able to see the outer pad. The bit between the backing and the disc is the brake material. Normally if a turbo is going you will hear a shrill noise when you come onto boost (terrible noise). They do tens of thousands of RPM so its too fast to sound like a scraping noise.

Hope i helped.
