I was just wondering how accurate the g-tech meters are. Anyone got one that can tell me??

A mate got one, we have done some tests and the bloody close, If they tell ya you've done X time then you have, as long as there setup is correct....

Cool so it is a cheap alternative to a Dyno??

I dont know about that, its a good tool to know if you've got your 1/4 mile sorted though.........

As long as you enter your vehicles exact weight with you in it they give a very close rear wheel power figure. You'll need to chuck your car on a weighbridge just before you do any power runs.

They can be accurate, but mine is "consistantly" inaccurate, which isn't bad either.

I have an older style g-tech pro (small radar detector style). There is a new model available.

It consistantly showed my 1/4 mile times about 0.3-0.4 seconds more than actual. I took it to the strip a few weeks back on six runs. It showed my MPH trap speeds about 2mph higher than actual. They claim to be good within 0.1 sec????

Yep: note the fuel level in your tank and go to a weigh bridge (your local tip), with you in the car. Transfer the kilo's into pounds and enter into the g-tech for RWHP readings. They're not too bad.

So, they're not always totally exact, but consistant, which allows you to use them for testing and tuning and note any improvements.

Don't spend $300+ on them either. You can get them for $50-100 on ebay.

All I want to do is when I do mods to see if there is a difference and roughly how much.

It will be fine for that purpose.

I just got one the other day and as others have said, if they are set up correctly they are accurate. For power readings you need the correct vehicle weight, and for power and 0-100kph/1/4 mile runs you need a dead flat stretch of road. Any road that isnt dead flat will make the reading inaccurate, but even then if you test on the same stretch of road each time it will be consistant. Great tuning tool IMO.

my house mate has one of the latest models and he has set it up for his GTR dead spot on. He was able to replicate his 1/4mile runs and power levels in the gtech.

with this thing he had to enter not only weight, but also the cooficient, 4wd, etc

we started setting it up for my car and get it pretty close, within .1 sec. dunno about kW figures as every dyno in town reads something different for my car

but yes i belive it a rather good tuning tool
