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.

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.

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.

      Before I commit to it as I already have the wastegate off the car, would you change it to the 9psi spring instead of the 12, or whack it back on now and try your suggestion?   Edit: Actually I might just swap the spring and see what the logs say after another few pulls, as we know it's still spiking without the Mac valve in the picture so I need more data without the Mac valve trying to combat the issue.

      Sounds good Hmm suppose the main thing is, how much do you care about this car? The filler doesn't make for a very good water barrier lol. If there was a tiny little bit of rust forming now, that in 3 to 5 years time becomes obvious under the paint (starts to bubble up), would it bother you?

      Mistakes were made, my R34 Story

      I already have the ability to datalog the voltage... what I can't do is correlate it to what the gauge is showing when I'm looking at the data at a later date. Or something like this. Except getting the oil to 125C+ involves me going 200+kmh at the track so you can imagine this is a little tricky unless I do something like note what the voltage is when I am at the top of 5th gear so I have a point to reference on. Drove car today. O2 still reading richer because hopefully not a leak instead of massive restriction I've introduced. Car really doesn't sound like a LS. It's quite strange. Pulled a bit of fuel out up top. This does potentially explain why my spark plugs looked like the car was running pretty over-rich. If I was tuning it to a ~12.7 which in reality was far richer than that in the past. It will be handy to have the dyno WB to compare my WB to to compare notes that's for sure. At this point I'm happy to just sit in the passenger seat and tune the thing given I've got about 7 million hours on the platform lol.

      Infiniti Q60 Navigation Update

      Yeah I understand you have to pay for an updated map or subscription service or something. But I can't even find a current map for Australia. My map is dated 2017, but didn't this car version still sell in Australia until 2021?   Also, just as an aside, the navigation system warns you of traffic incidences ahead.....why would they include that on a map they knew is not receiving live information. I am forever going to be warned of an incident that probably existed for 30 minutes 8 years ago.
