How does it receive data from a 12v power outlet?

You must mean the "ecu port" next to it..behind the ash tray?

And how the heck does it measure power? Accord's have a built in dyno or somethin?

 

yea i dont understand this Gtech thing. i kno there are some other similar products but i dont understand how they can measure powers and etc...

 

GTech - It uses the g-force exerted by your vehicle accelerating and a sensor in it to measure what your quarter mile time is and everything. It then calculates everything with your inputted weight, etc of your vehicle and data that you give it to give you your estimated 1/4 mile track time, horsepower, or however many g's you were pulling on your skidpad.

It's usually within 0.2 seconds of your 1/4 mile time and 10 hp from what I've observed from cars that dyno or track after they test it out.

 

Oh yeah, and your GVWR weight should be posted on your driver's doorjamb sticker. subtract an estimated 150 lbs for each seatbelt you have, i believe, from the total F+R. (that heavy number)

 

.2 seconds faster or slower in the 1320?

 

from what i've seen, it's usually 0.1 or 0.2 seconds faster in the 1320, giving you the impression that your car is better than it is. (probably some marketing scheme)

 

open your driver side door and look in the sill your answer is right there h:

 

theres a DX accord i've never seen one
i know theres an LX, EX and SE

 

there are a lot of them

 

g-tech's work on the idea that in order to move an object weighing a known amount (lb) and a known rate of increase (g's) it would take "X" amount of energy (HP) to do it. It can calculate speed by using a formula like speed = oldspeed + (g's/time or time/g's) and repeating it hundreds of times a second. if a car was going 0mph and then had a g force of .2 for 1 sec it will be moving and 4mph (numbers not real all concept for idea that has been proven by some physicist I'm sure)

The acurateness depends on how close you get the weight input, scales at the drag strip would be nice, and how close the level the unit is set up (I think body roll screws with results a little also but I don't remember reading about it). And it will vary from a dyno. the variation should be dyno hp minus the hp loss to wind drag and other things not afecting a dyno test including bearings on wheels not turning on dyno (normally rear for us and is almost no drag but some drag does exist)

It is still a good tool for a before and after impact of a mod on a car. Oddly though mine shows that I have more HP with struts set loose than I do with them set firm, hense my body roll thery mentioned above. Because I have no wheel spin and struts don't affect HP. Drives should keep eyes on road and let a friend read the g-tech.
