Got a trip booked in July.

Anything I need to do to the car before I go on track? I'm no driving good so expect to hear about various rubbish cars scalping a GTR. However, I'm more worried about bonnet poppers going off.

So cancel them? What about the ecu, can I bypass it with a wire or something or just disconnect it?

Anything I need to do.

Going for a full service, new bell housing and goodrich brake lines.

Bonnet poppers going off means you are expecting to prang it, which you won't right so don't worry about that!

I'd say good brakes/tyre's and take your time. I was there last year and though I didn't drive my car myself, I did go out in an M experience car which was great.

I heard the poppers can go off just by going over the kerb or on the grass, even rumble strips!

A few have so try not to go over kerbs, grass, gravel traps or bikers. You can dissconect at front of car which will stop the bonnet popping.

If you have time to stop in Holland message a guy called Richard Landsaat on B35 and see if he can do the ecu bypass for you, it doesnt take long so cant cost much.

Where at the front? What will be the effects, will it throw a code and put a light on the dash? Will it go into limp mode and will the code/light reset if I reconnect?

Is there a wire trick or something I can do on the crash ECU?

Ah, just read the second bit. Yes, wire bypass. Doubt I'll have time to visit anyone, is it difficult to do.

The only thing with disconnecting them is are the sensors one time only ??? - ie: if you triggered the system with it unplugged the bonnet wont pop, but when you plug it back in it may go off ???

Bonnet Cancellers

I'm off to the Nurburgring in a few weeks, I too was concerned about the bonnet 'popping' so weighing up fitting bonnet cancellers, here's Iain's response from Litchfield's, thought i'd ask them as they're probably one of the busiest GTR specialists dealing lots of tracked cars:

"In all the time we have been working on the GT-R I have only seen these bonnet rams go off on a couple of occasions and only when a car had fit a large object.

We would not supply or fit these as it could turn into a nightmare if you hit a pedestrian and they didn't go off."

A sensible though very corporate response. Though I would not expect to find pedestrians on the ring, bit there are large kerbs, grassed areas and road cones.

So there are bonnet cancellers, is there a bumper sensor canceller?

Fitted for ring duties only of course.

Yes, R35Audio sell them for circa £100 incl VAT and postge, as do JM imports.....

R35 GTR Bonnet Cancellers

I'm tempted to fit a set just for peace of mind.

as a newbie you shouldn't be going anywhere near Kerbs at the ring.
I didn't intend to hit the Armco at blyton either...

Besides, I've read reports of them going off when driving through a fast dip, or rough anything. Just don't want that to be me.

Same thing, the cancellers purpose is that should the bumper sensors send the signal to the ECU to fire the bonnet actuators, the bonnet actuators don't fire.
If the ecu goes off it will still throw a dash light right? And the pedestrian ECU requires replacement after?

Ive been round quite a few times, and its been fine, but get the cancellers if you want added piece of mind :D

From all the responses, you can reset the ecu if they do go off.
