I went to the track with my friend in his Lexus SC400 and tested out the accuracy of his g-tech with the real track. The g-tech showed .02 (two-hundreths) slower of a 1/4 time. So I felt it was pretty accurate and we tested it out on my 2K2 GLE (auto).

Results:
0-60
6.54 (3 people in my car)
6.19 (alone)
6.22

1/4
14.79@99 (3 people in car)
14.58@100 (alone)

My only mod is a pop charger intake

Peace,
Daniel

great times!!!

Even with 3 people!!

Can it be true...14.6(auto) and 14.3(6sp)
I don't think its right...and 6.2 0-60 is also too fast...you should get around 6.5 because the Infiniti I35 does 6.7 so you should be around that.

6 spd ... yes. I was there when dmb ran his 6 spd.

Check his times in the Island Dragway times thread in the NE forum.

damn, something is fishy, those trap speed are very high. got any scans of those times or the conditions they were run under.

They were G-Tech pro times. The G-Tech pro does not average the MPH over the last 60 feet like the track does. BTW I agree those times are a tad quicker then they should be.



2001SE, were did you read the I35 did 6.7 0-60? I have seen 6.9 and 7.0.{C&D and MT}

damn, something is fishy, those trap speed are very high. got any scans of those times or the conditions they were run under.

In real world testing, the Gtech units have been shown to be VERY accurate. However, they do not take into account if there was a slope to the street, headwind/tailwind, etc.

However, I noticed the high speeds for the 1/4 mile also. Keep in mind that he DOES have a pop charger intake, which could make a difference if the stock intake is restrictive. It could really help the top end power/acceleration.

The 14.3 time that everyone is quoting for the 6 speed is NOT an optimal reading. He was shifting before redline each time and he was new to a manual tranny. Impressive to say the least! That 14.3 that he ran can only get better with time and practice.

I do not know if the times are accurate due to slope, tailwind, etc. But I know that the Gtech units have been shown to be accurate, and the power-to-weight ratio of the Maxima is quite high - high enough to support these times.

Also, the GLE is the lightest Max - and comes with lighter 16" wheels and tires that will also create a slightly higher final drive ratio.

I think you confusing the GLE with the GXE, the GLE comes standard with 17's and is the heaviest.

Doh! You're right. I did mean the GXE. With that "X" in there, it just sounds like it should be the top of the line! Plus, to further muck it up, Toyota uses XLS for the top line and LE for the lesser lines. Momentary brain fart, indeed.

The SE is the only one that matters, anyway.

Ok, wrapped in foil, flame away!

Thanks guys for the comments.

I am definitely going to the track friday with the g-tech and check the accuracy. Plus the track should be more level than most roads. I thought the times seemed a little quick, but I'll just have to wait until friday. The trap speeds are probably 2-4 mph hish because it measures the mph at 1320 ft. instead of averaging the last 100 ft.

Daniel

doh, i thought these were actual track times. i got confused. ya at a real track you will be a couple tenths slowers and the MPH will be about 5 lower. good luck.

So when are the TL-S ppl going to show up and refute our claims and that "they've got NAV" ??

Jsut as soon as they figure out how to fold down their rear seat and heat their steering wheel!

Ugh.

The TL's rear seats don't fold down? haha! My Accord's do!

(I actually knew that - I'm just being facetious :-)

i need to make a smiley that says G-TECH sucks..

Do TL-S's even have handbrakes? I like handbrakes...

Sorry, the GTech can be accurate, buy too many people don't know how to use one properly, so I just dont listen.

Go to the track, than I'll listen.

blah. - mattsy

i don't think they have handbrakes.. i know the CL-S doesn't.. that was a question from the CL-S owners when the 6spd came out.. if they would have handbrakes or not.. i am not sure about the TL-S.. but the CL-S has no handbrake..

They have a foot-brake (GM style) e-brake.

They're good for lateral G-forces...a horrible representation of 1/4 mile times though.

So where are they going to put the clutch pedal when the fabled 6 Speed version comes out? See, so now we have them figured out there is no 6 speed manual coming out in that car.

Stereodude

On the streets, yes. My G-Tech told me my Accord V6 with intake and plugs got a 15.46, but I know that's a load

But if you run one at the track while you're also getting your time slip they're usually pretty accurate except for the speed being a few mph faster, but that's already explained.

according to the CL-S board.. its out and people have driven it

I was actually joking. Besides just because a prototype exists doesn't mean there is really going to be a production version.

Stereodude

facetious, i love that word.

G-techs can be very accurate at times and very inaccurate at others. Too many factors come into play. I've heard that wheelspin somehow "tricks" the G-tech to thinking that your car went that actual distance or something.

If you use a G-Tech at an actual 1/4 mile track it'll probably be pretty accurate. But the accuracy goes way down on regular streets. Things like bumps in the road, rear suspension dip on hard acceleration, and other little things can throw it off. Bumpy roads are definitely bad.

If you ever use a G-Tech on normal streets and not a track it's best to do whatever test your doing in *both* directions on the same street. That way if there is a very subtle uphill or downhill, or even a headwind or tailwind, running in both directions a couple of times and then averaging the results will cancel out the above. That's the best way to get accurate results on normal streets.

G-TECH SUCKS!!!!!!!!!!!


thats how the CL-S owners run high 13's on headers and other mods.. G-TECH

G-TECH will never be able to replicate a track.. the 60ft.. the nervousness sitting at the light with everyone looking at you.. racing another car.. all those factors... G-TECH can never replicate..

You're right Sprint. A G-Tech is no substitute for a slip time, and anybody that declares a time by using a G-Tech w/o mentioning that it was a G-Tech is a moron. But it is a good tool that you can use to see how your cars performance changes with different mods and conditions. But the absolute times it gives won't always be the most accurate. But the differences that it gives are still useful. But you have to understand how it works and what its limitations are to use it effectively.

Do the 1/4 run on a downward slope to run 13's.

The mags ran the TL-S/CL-S uphill when they did the performance tests. That's why they only run low-15's stock. They're really capable of 13's. I can beat a new M3 in my TL-S.

My NAV puts me into the 12's, which will waste an M3. My TL-S is fast.

na-ah. I wasted one more than you did. And now that I have headers I'm in the 11's.

Headerz own jOO

Can't wait for the Comptech SC. I'll be running 8's in no time. SC ownz jOO!

Only word in the english language that has all the vowels in order in it.

ya pretty much the only thing a G-TECH is good for is for comparing your car before and after mods on THE SAME STRIP OF ROAD. other than that the times are meaningless compared to other times. you prolly will get similiar times using a g-tech on a track IF you hook up good, other than that they are only usefull for comparing your car.

you mean getting 8's 0-60

naw, 1/4 mile. We're talking about Keving's very lightly modded TL-S here, and we all know how fast THOSE are

I did a downhill 1/4 with the G-tech and broke 10's with my new TL-S! ......

But you've got NAV. So does Keving. That puts your car in a different class so it doesn't count
