What really matters is where is the AFR under large throttle openings and when the revs rise.

As the revs rise I would expect it to move into the mid 12's & then on to high 11's. So best thing is to set the logger going and then go full throttle in 3rd or 4th to the red line and have a look at the log.

Thanks for that Rich, my understanding was that my figures seemed right form what folks at NAGTROC and COBB forums have said.

That said, I did try to log but the AP wouldnt do it. I can get live info but no logging.

Did Joe@cobb give you an updated link for software to resolve EDM logging issues?

[Rich-GT]

No update I have seen. Logging does seem to work, although I have a list of issues. Have had no detail from Joe as to what aspects he is working on.

Was the 18.8 on the overrun or on acceleration? What about the 14.4?
I believe turbo cars want to be run richer than that for safety.

I am pretty sure that with that I saw a note from Benji that logging does not work yet but will soon.

Been following the various GPS mounting threads for a while...bought a Tomtom 740 a few weeks before my GT-R arrived, and it's a great bit of kit - if you do a lot of miles the live updates are really good. But to my knowledge there's no standard vent mount available for the 740, which is why we've been seeing all these different ways of mounting it.

I think the vent to the left of the steering wheel is a good place to mount it, so I bought a mount for a tomtom xl - six quid from ebay....got my dremel out and ground off a couple of little lugs at the very front of the mount to leave a flat piece of plastic. I then took the dremel to the standard mount and cut everything off from the swivel ball backwards. Then with quick drying araldite glued the two together



The problem with all the vent mounts is that they rely on spring pressure to keep the thing stable. Not good in a car with a built in G-Meter. So I took off the spring mechanism and fixed the mount with a couple of cable ties




Happy with the result - very stable and no hard wiring required - the power socket is just below the vent

Very neat solution guyblue - nice work How fiddly were those cable ties to apply through the vent?

[David.Yu]

Nice work Guy! I presume as you had to use cable ties the mount is semi-permanently installed, i.e. you can't take it off when you park?

Just wondering if it poses a security risk if some lowlife decides to go looking for the unit in the car.

I've just ordered a 940 Live from Amazon (because it must be "200" better than the 740, right? ) and will be looking at different ways of mounting it.

I hear the screen isn't too good in direct sunlight, so that may be needed to be taken into account.

Good work Guy, that's my kind of modding! Take something, cut it, stick it, bend it, and get it to work!

Marvellous!

[guyblue10]

Thanks Guys....hmmm, there's a lot of Guys on here...unusual

Yes Guy - I had to make multiple bends in the cable ties to make them curve back on themselves so I could get a hold of them. Bit tricky but not hard

Yes David - I'd need a knife or a pair of snips to remove it, so there is the security angle to consider. I just get the feeling (rightly or wrongly) that it's the type of car that will either be targetted for vandalism (as we've already seen with the guy who had somebody carve his initials in it), or for complete theft rather than the opportunist sat nav thief....I plan to do high miles in mine and leave at at travel lodges (generic term) overnight, so I guess we'll soon find out.

I've heard on the 940 that the volume actually goes up to 11, so yes, I think you're right, a far better unit....

Cheers

Now I find out the 940 goes to 11.

Looks like my 740 is going on ebay......

I think the only difference between them is the 940 comes with US and Canadian maps and I drive in the US a couple of times a year on average.

Does the 740 have an FM transmitter for giving voice guidance and MP3 playback?

Cheers for the idea but my problem is a bit different. My vent bracket grips the vent slats no problem, but the weight of the 740 actually twists the entire vent when cornering, so it ends up sitting at 10 to or 10 past twelve.

Drive through a series of S bends and the bloody thing is al over the place.

Anybody know how to possibly tighten the vent unit so it cannot rotate?

No FM transmitter on the 740, MP3 not sure...

[David.Yu]

The rotating vent issue means that is right out for me, that would really annoy!

Out of the options so far, I think Charlie's is the neatest, assuming of course the windscreen mount it comes with is not up to it...

I try not to fiddle with the sat nav too much whilst on the move and leaning forward slightly to do so is no biggie to me.

The 940 has an FM transmitter, but seeing as I probably won't bother to load it up with my music, that is not likely to be very useful to me...
