My best 0-60 time !!!
Here's my best 0-60 time using the G Tech Pro @57 degrees F. No mods 'cept a K&N airfilter. Not too shabby for a V6. My '97 BMW 540ia with the G Tech Pro did 0-60 in 6.35 seconds.

Nice 0-60 time 
.
Why didn't you get a 6 speed 540i? Weren't they the fastest sedan of there time? Most of BMW automatics aren't the best in the world. There manufactured by GM. So there really smooth shifting; but lack the performance apsect

I bought the BMW used. Nothing touches a BMW for the complete sporty feel. I have a '98 Mercedes Benz E430 (V8) and it feels more luxurious than sporty. The Benz is definitely a higher quality car than the Bimmer. Just my $.02.

Hey Tundraman, I drove my uncle's 97 E420 AMG before the lease expired June, '00.......very, very nice.

I ran an acceleration test in the E430 under the same conditions and the 0-60 was 6.7 seconds. My Acura is actually faster!!! Damn! I'm gonna have to get an E55 now (I wish!).

How acurate are the GTECH's really? Tundraman, I have a 540iA as well, but it has sports package which gives me the 3.15 diff vs. your 2.87 on your 540i. I ran GTECH on my 540iA but then I had Dinan Stage1 and Tranny software, but to my freakin surprise I hit 60 in 5.3 sec so I totally discredited the GTECH cuz I know that there is no way in hell any 540iA's will hit that...just my experience.

My 540ia was stock. A few years ago a car mag tested the GTech Pro and said it was very acurate. I sorta believe the results.

I think sometimes G-Tech is a bit off, especially if the car has rear dive, front lift up going on....
With G-Tech, I have clocked my W140 doing 0-60 in 7-Flat, which is 1.5 sec faster than factory... and I know it too well, it's not possible.... 7.5 - 7.7 maybe, but definitely not 7-flat...

--G-tech real-life accuracy is +/- 0.1 second
--Actual weight of vehicle inputted into G-tech. Unless you weigh your vehicle (with driver inside) on one of those trucker scales, you'll never really know exactly how much the entire vehicle weighs.
And for someone (I believe it was NSXNEXT) who stated a while back that you don't need to input weight for calculating 0-60 times on the G-tech--I believe that is incorrect. Remember, acceleration=force/mass. So obviously, you would need to know what the mass is (in addition to force) in order to obtain acceleration. No other way around it, unless you know how to cheat the laws of physics, or the G-tech itself.

a period of time.
But the GTech uses an accelerometer that measures G-Force or Gs to keep track of acceleration (1 G = 32' per sec per sec). By extrapolating how fast you accelerated over set amount of time you can derive speed. By constantly updating the speed you can determine you long it takes to get to a set point, i.e. 60 mph.

BTW--the definition of acceleration I cited is known as Newton's Second Law of Motion.
In any case, as you noted--the G-tech doesn't care how big or small the object is when it comes to 0-60, since in the end all it's gonna do is spit out a time. I raised the issue because I thought that I read somewhere in the G-tech manual that you still needed to input the weight even when attempting to measure forward acceleration.
Oh well--I better read up on it again...

P.S.: my apologies to NSXNEXT...you're correct, too.

The GTECH tilting during acceleration -- due to the amount of "squat" the car experiences -- causes the unit to give optimistic readings.
Even if you initialize the unit perfectly, when you take off, the "current" unit will overvalue the acceleration due to the effect of gravity and tilt.
It the front-to-rear tilt of the car is only 1 degree, it will be off as follows:
gravity * sin(degrees_of_tilt) + real_fwd_accel * cos(degrees_of_tilt)
Assume .5 G of acceleration:
(1G * Sin(1 degree) + Fwd Accel * Cos(1 degree).
(1G * 0.017452) + (0.5G * 0.99985) = .517377G
Since the GTECH is using acceleration to derive all of its velocity and distance data, the "actual" .5G acceleration (for example) would be read by the GTECH as 0.5174G which is about 3 % too high!!!

With new goodies installed (Comptech Headers, AEM CAI & Comptech Exhaust) @48 degrees F, my TL-S did 0-60 in 5.91 seconds and the 1/4 in 14.4 @101.7 mph. This thing screams!!!

funny if i remeber back when the CL-S was first about to be released the preview from acura stated from independant studies the cl-s does 0-60 in 6.47.......i guess they used a gtec

Yep. Stock wheels and tires. My technique is to leave it in 1st gear, give it a little gas while holding the brakes, then flooring it after releasing the brake. A few hundred rpm's before redline moving the shifter to 2nd. Unfortunately in SS mode the trans shifts a tad too early giving me a slightly slower time. Putting it in 1st allows me to shift it manually, giving me the most out of my powerband.
