Any chance it was the "magnetic" black paint colour??? Possible EMI issue here.... :stirthepot:

I seriously doubt fields from a power line are strong enough to do anything. They fall off as the square of the distance. In addition, there's more EMF from the ignition system of the car than anything else. The ECU is shielded from this. (H3ll, the car is basically a Faraday cage anyway - the insides are surrounded by the metal body.

In any case - a very close call. I'm glad you were not injured. The fact that this particular ECU was a bit flaky leads me to believe that the "re-set" did not completely solve the problem - maybe a hardware failure? I hope things get sorted quickly for you.

Ah HA! :mad:









J/K, hope everything works out to your satisfaction :D

subscribed! in for updates!

UPDATED! Link to damages. Rather than spam with 10 pictures.

Still waiting on reports from dealer, etc. I'll keep updated.

ouch glad to see ur ok

=( breaks my heart to see these pictures. but glad ur okay.

Sorry you had to experience this. Hopefully Nissan will stand up and do the right thing and not say it was "due to operator error". Good Luck!!

LOL - in that case every electronicly controlled car should be in the ditch right now since your engine bay is full of high voltage lines (eg your ignition!!)

Your ECU is desgined to be shielded from that sort of interferance. The stuck throttle issue is the gear lash on the throttle mechanisim. Simple fix.

Doh - should have read the full thread - beat me to it!

Nissan's fault? Hope the OP has insurance.

he doesnt know how to drive?

Hey, I posted in here and it was erased. Other people posted jokes. WTF? :shakes head:

you're luck you didn't have a blowout driving it back to the dealer. that one wheel is dangerous looking

I wouldn't be so quick to say that these issues are or aren't EMI related. Electric and magnetic fields are very complex. It usually isn't as easy as just saying that some particular unit is shielded by the body or some other means.

The car's body should do a good job shielding from electric fields but magnetic fields are a different issue. Thin sheet metal won't completely shield magnetic fields. Even though the ECU may be shielded the shielding doesn't prevent fields from being coupled onto wires entering or exiting the ECU.

Additionally, fields don't always fall off at at rate of 1/R^2. I work on some extremely high power equipment that was expected to produce fields that rolled off at a rate of 1/R^2 when in reality the measured results showed that the roll off was actually 1/R. The actual roll of of a field may be anywhere between 1/R to 1/R^4 depending on the source, location and the make up of the field.

With all that said I would tend to agree that it isn't likely that the problem is related to power lines but I would be looking closely at inter-compatibility issues with other electronics in the car. Either way it should be interesting to see how all of this plays out.

Sorry for being such an engineer.....

WOW 9%, NO, but Hell NO!! :shakes head: Not even in an used car!

370z can be grabbed for around 30k USD, thats not alot of money for a sports car compared to the germans

I'm 21 with 7%.... And OP I'm suprised that tire didn't blow on you

worth noting though that nissan has the electronic throttle cutoff feature where the throttle shuts if the brake is pressed, even if the throttle pedal is pressed. did this feature also malfunction? that could hint at the source of the problem.

But is this feature on manual transmission cars? (Heel and toe comes to mind)

yes it is also on manual cars, i tried it myself. and yes, you can still heel and toe just fine, i tried it myself. i don't know how it happens but i'm guessing maybe pushing the clutch pedal overrides the throttle cut off.

Can heel and toe for sure, but I'm not sure what happens when the clutch isn't pressed.

But uhh, here's a picture of the start of the corner. I went back and checked out where it all happened. I did NOT nip the corner as I first thought. It was my only logical explanation as to why my TCS would have lit up. So, now I'm completely clueless to be honest.

Coincidentally a grounded power line right there. But, I have a hard time believing it's the cause myself. We'll find out soon :D

The wheel spin sensors aren't that shielded from EMI - maybe they're feeding bad data...same with the gyros in the car which tell it which way the driver is intending to go vs where the car is heading.

i donno, some times people think they are on the brakes while they are hitting the gas while they smash into stores and poles and crowds of people.

Just out of curiosity, what's your source of that info? Since the Toyota debacle, I've been wondering whether or not the 370Z has a brake override.

Just Google it.

Per After Toyota Troubles, U.S. Weighs ?Smart Pedals? in All Cars - NYTimes.com

Per Japan carmakers studying brake override system | Reuters

Gotcha, but I'm wondering if there's anything documented that the 370Z has the override. I would think that it would be mentioned in the Users Manual if the Z had it, but it's not (as far as I know).

Yeah I don't recall seeing it mentioned in the manual, but FWIW, over in this thread http://www.the370z.com/nissan-370z-g...l-a7-370z.html I've seen it mentioned that you can't launch the 7AT by standing on the brakes with your left foot while depressing the throttle with your right due to the override.

I don't know if thats really a brake override. You can't rev the manual in neutral over a couple thousand rpm either, brakes on or off.

Sorry to read about this. I have the exact same setup as you, but my car is an early build. I've never had an issue thankfully.

I could redline in neutral. That I'm sure of. You can't?

The car only revs to 5k in neutral.

Really? I have never tried, not that I want to. But, really. Car has a factory 2 step. :tup:

When making a video with my Berk exhaust we hit the limiter, that was the first I had ever seen of it.

Mine revs to 4k in neutral, if I remember correctly. When I made my exhaust vids (the stationary ones) I had to put it into 1st and keep my foot on the clutch to rev up towards redline.

This story just doesnt make sense... which if its true really doesnt anyway... but nothing from these pictures proves that what he said happened really did... I didnt really read this, i dont know how old the OP is but he could of just hit it around a turn and spun in a circle and caused the damage shown... And out of the momment decided to use this as an excuse to make himself feel better.. my apologies if thats not the case but it's just how I feel about this.

Im hard pressed to believe what was said to happened, happened.. but im in for updates

I see. So only in neutral with foot off the clutch will it limit. Darn.

Since the car wasn't moved after the crash I assume Nissan will be able to tap into the EDR and see exactly what happened.

In for updates,
To the OP glad to hear your ok.

It will be interesting to see what the black box has to say..... :facepalm:
