GT-R + internet = massive hype

Philip
True, but the massive repair costs aren't hype. I spoke to a performance car insurer yesterday and he said claims for minor front end prangs on GT-Rs were causing quite a few insurers to review their stance on them.

I was as sceptical as anyone else when the first "£11k" story came out and prices were apparently adjusted, but they are still stupidly high.
It's a serious problem Nissan need to sort out IMO.

In the meantime, we need the geniuses at GTC to come up with an aftermarket bypass system urgently! :)

OK so lets get practical about this. Putting aside for the moment the on the road issue and any legal or political correctness associated with disabling the sensors, it is obviously complete lunacy to leave them connected for any off road event.

So I have had a quick look, and as described there are three sensors mounted just inside the grill.



One in the middle just behind the badge.



And two more on each side towards the edge of the grill.




Each has a plug on it and the loom leads as described to a single plug over by the hinge side of the bonet stay.

So I tried unplugging the plug to all three.



Fired the car up and everything seemed to run fine. Except as expected a warning light, with a nice picture of an exploded bonnet flashes at you.



I plugged back up and the light continued to flash on restarting.

Checked for error codes with the AP and there were none, however doing an ECU reset with the trusty AP put the light out.

So This may be the way forward but I have a few concerns.

First without knowing what is in the sensors or the input circuitry on whatever they feed one cannot be certain about leaving the inputs floating. However I find it very unlikely that the system will trigger without the sensors connected.

Of bigger concern is what happens if you were to hit a "cone" when on track and then connect back up again afterwards? It is possible that the sensors are a one hit wonder and stay in the triggered condition?

So if thats the case then you would need to remove the sensors, which makes this a much more difficult job if you want to disconnect and reconnect for the road, or for a service?

What do others think, and has anyone got any more data on the sensors?


All that said I realy feel that Nissan should provide an "approved" method of disabling for the track?

Pops the bonnet away from the engine block so they 'the pedestrian' dont deform the bonnet into the hard surface of the block.

You have to have a minimum distance between block and bonnet, without it you have to have a pop up system.

Oh my god just imagine coming home from a great track day, park the car and decide to plug the sensors back in...

BAM:chairshot

You might just die getting killed by a system that's supposed to save others...

Though you have to say it's not Nissan's fault, they just follow the rules. The Jag XK has the same system and I guess those are not tracked as often (but they might hit pedestrians more often:D)

I don't believe it. It must have been a faulty one.

Anyhow, you're not supposed to hit the cones! :)

And I wouldn't want to be the one who has to explain to the cops why my pedestrian launcher was disconnected. :)

Excellent work Rich! I defiantly concur with your thought on the possibility of the bonnet launch control system firing after a re-connect having twa**ed the front end with a feather duster! The sensor look sealed for life and are more than likely solid state devices, it would be interesting to see if your "G" meter still worked on the MFD after these were disconnected??

It would be REALLY good to know if these need to be connected for legal reasons once the vehicle has left the showroom or are they a "nice to have" feature, if they are not a legal requirement I would opt for total disconnection and remove the actuators as well ... as a double bonus it is bound to save some weight too! :)

They are for sure a "must have" in the GTr to make it legal....but tbh,do you really think a police officer will put your car of the road as you dont have them installed??

Policeguy: Hello sir,could i see your driver licence and car papers please?
GTR driver: Yes,for sure,everything is stock,only the usual mods like loud exhaust,cobb AP with 700hp mapping,open filters,loud blowoffs and totally worn tyres...
Policeguy: Cool,everything is fine then.......:thumbsup:
GTR driver: Yeah,give my papers back then...
Policeguy: No,your pedestrian launchers are not installed....i will clamp your car now untill you got them installed again....you bastard


:D

My plan until somthing better comes up is to pull this plug when on track. If I hit anything I will then not reconnect.

However what I would like to do is work out what is in the sensor, and establish if it's a 1 shot or if it just triggers & resets?

If anyone has completley removed the sensors and has no intention of reconnecting them then I will happily take a look.

I expect this to be a completely stand alone system rather than integrated into any of the MFD functions. A dedicated ECU has been mentioned, that also has to be replaced when triggered, can anyone confirm this?

It looks like this is a different system than that fitted to the Citreon & Jag, as that has a light tube in the bumber with a sensor at each end.

If anyone knows more about the Nissan system them please post it up?

LOL!

I was not concerned with a random inspection but more a real situation where an accident had taken place and the system had not deployed, chances are no one would really know ... unless it was a serious accident with real causalities and the investigation team was called in to inspect the vehicles which is not uncommon in the UK.

Its stand alone,as everything else works normal with the bulb on....:thumbsup:
