AndyC Posted September 11, 2006 Posted September 11, 2006 Last week I finally got round to ordering the much talked about Pete Spill Grounding Kit. To be honest I was a bit skeptical that it would have that much difference to the car, even though there's been some great feedback on here from different people. When I opened the pack that had arrived (very promptly) from Pete I was even less convinced, I mean its just a bunch of wires how can it make that much of a difference? Anyway, I cracked on and got it done in just under an hour but this was also while being on the phone for most of it so its well doable in under an hour. I must confess that this was down to the easiest and most understandable instructions I've ever seen All fitted nice & neatly and nothing difficult about the job at all. I've had her for just under 18months now and I couldn't believe the difference as soon as I fired her up - straight away I could hear the difference, she was idling much much smoother. But it didn't stop there, went out for a short blat and the kit has really ironed out everything right through the rev range. Also I used to have a bit of a lurch (almost like a slight bog down) when I'd changed from 1st to 2nd (and no it wasn't my driving, it happened to everyone who drove the car) which has now gone completely. All in all absolutely fantastic, I can't believe what a difference its made to the car, anyone that hasn't got one get one now!!! Quote
Harewood Posted September 11, 2006 Posted September 11, 2006 I can fully agree with all you say. Fitted my kit a week back and again every thing felt smoother. Quote
Kennydies Posted September 11, 2006 Posted September 11, 2006 what is this kit and what does it do? Quote
AndyC Posted September 11, 2006 Author Posted September 11, 2006 what is this kit and what does it do? To put it simply its a wiring kit - theres 6 wires which you connect to different parts of the engine & battery. Like I said above, really simple & makes a massive difference plus only 60quid!!!! EDIT - sorry forgot to add that it makes the earthing of the car MUCH MUCH better, the theory is that cos of this the ECU can see a cleaner signal and perform better. Quote
M13KYF Posted September 11, 2006 Posted September 11, 2006 its basically a set of earthing cables which helps to earth the engine better and make it perform smoother. more info here http://www.350z-uk.com/forum/viewtopic ... highlight= Quote
Guest prescience Posted September 11, 2006 Posted September 11, 2006 Not everyone believes that it makes any difference at all. Most say it makes the engine feel/run better. Some even say it gives you more power/better MPG - though I can see no justification for this whatsoever Quote
Kennydies Posted September 11, 2006 Posted September 11, 2006 is it proven to make it better? May look into it when i come back from holiday. Quote
Guest prescience Posted September 11, 2006 Posted September 11, 2006 In another place some scientific tests were mooted (with Pete's backing) - though I am uncertain if these have yet been conducted Quote

Some even say it gives you more power/better MPG - though I can see no justification for this whatsoever I think the more power/better MPG may be a perceived benefit as its smoother. I've certainly got no better MPG. Quote
Guest prescience Posted September 11, 2006 Posted September 11, 2006 The tests proposed were IIRC 1. Simply fitting a better earth strap 2. Measuring the voltage drop across the existing earth strap. Quote
Spill Posted September 11, 2006 Posted September 11, 2006 Car still not running so haven't had a chance to put the meters on, when it's sorted I will post up. and just to confirm Some cars do react differently when earthing kits are fitted IMO it's down to the way the ECU is earthed...... .......the main reason why we need a grounding kit is pure and simple cost saving by Nissan and this has been proved. also THE KITS DO NOT INCREASE BHP, I HAVE DYNOS TO PROVE IT Personnally I never noticed an improvement in idle and yes I scepytical when I first fitted one, what I did notice more than anything else was trying to pull away from islands in second gear, it just wouldn't happen the kit sorted that and have never looked back. MPG who knows, I never get over 18 anyway cheers Andy Quote

Mine was obviously badly earthed cos the difference is massive, nice one to you Pete Quote
Sarnie Posted September 11, 2006 Posted September 11, 2006 Had one on both of my zeds and wouldn't have one without it now Quote
Stew Posted September 11, 2006 Posted September 11, 2006 My idle smoothed out too. I suppose it depends on a lot of things before the kit is fitted. Great piece of kit and well worth £60 - keep up the good work Pete! Quote
Rob_Quads Posted September 11, 2006 Posted September 11, 2006 I did notice when I put in my stereo how small the factory earthing strap was. I put a second one on to make sure I did not have any issues with the stereo. Going to do the earthing kit soon when I can steal some 4 AWG from a friend Quote
burgershot Posted September 11, 2006 Posted September 11, 2006 OK - so first i'm intrigued - then as i read more i am sold on the concept -and now i want a set of these - Do we PM you personally Pete !? Quote
AndyC Posted September 11, 2006 Author Posted September 11, 2006 Yep, just send a PM to Spill and he'll sort it Quote
stevie_350z Posted September 11, 2006 Posted September 11, 2006 In another place some scientific tests were mooted (with Pete's backing) - though I am uncertain if these have yet been conducted Conducted? Is that a joke? Quote
stevie_350z Posted September 11, 2006 Posted September 11, 2006 How techie do you have to be with this kit... what tools, etc? Quote
Sarnie Posted September 11, 2006 Posted September 11, 2006 How techie do you have to be with this kit... what tools, etc? I have done it and a don't own any tools. You need a 10mm spanner thingy and thats about it. Quote
max Posted September 11, 2006 Posted September 11, 2006 looked at these a few times, how do nissan look at them being fitted do they invalidate your warranty are nissan happy we are messing with the wiring of the z. max. Quote
lomoto Posted September 11, 2006 Posted September 11, 2006 looked at these a few times, how do nissan look at them being fitted do they invalidate your warranty are nissan happy we are messing with the wiring of the z.max. Nissan actually list a similar item as an extra Quote
max Posted September 11, 2006 Posted September 11, 2006 didn't know that i will have to check it out, cheers tim. max. Quote
AndyC Posted September 11, 2006 Author Posted September 11, 2006 looked at these a few times, how do nissan look at them being fitted do they invalidate your warranty are nissan happy we are messing with the wiring of the z.max. You're not actually messing with the wiring, all you're doing is adding some wires none of which actually mate up to the loom. In addition, you're using existing mounting points which are not currently being used. The only actual interference with existing wiring is to connect 1 wire to the factory earth point and another to the batter neg. I've got no concerns about it invalidating my warranty Quote
