I picked one up and went through all the calibration steps etc. Anyway I was wondering what's up with the hp and tq readings? I understand why it will give a lower reading but I'm curious as to what others with na 05+ gt's have gotten with it. I got something like 228/247 on one run (i guess it takes the reading from second gear..). Don't really know what to make of that. lol.

I was also wondering about setting up the pitch thing. It says you need to do runs at a track but that doesn't really help me. It says the stiffer your suspension the lower the number. I have the stuff in my sig so my suspension is way stiffer than stock. The standard it says is 2.0. I put mine to 1.5 as a guess but really dunno where that should be.

 

I have one, actually the RR version I believe. I fiddled with it for a while when it was new. Now it has been in a box for a year or so. I fiddle with it every great once in a while.

First off, the HP and torque numbers are worthless. You really need the exact weight of the car as loaded. Then be on perfect ground, with no headwind, and no wheelslip, etc etc etc. Even then, the wind resistance of the car plays a factor. My big block mopar, which is putting out 475 or so to the crank, would routinely show around 290-300hp readings at the tires using the g-tech which is way off.

I do believe the 0-60 and 1/4 mile times are correct. Problem is, around here especially, finding a place to use it with enough room to do a 1/4 mile run without getting arrested and getting good traction are a problem. I find the nice quiet roads usually have private houses on them and would frown on a bright blue car flying by at 100mph+ trap speed.

Even when I did manage to find a quiet, long, flat, road that I could come to a complete stop on, getting the car to hook up was always the key to getting the times right.

Also, one of my friends got pulled over with his suction cupped to the windshield during a run. The cop knew what it was from the tach on it, etc and gave him a pretty nice lecture and a ticket.

They are fun, but I found it lost it's appeal after a month or two. You really have to read the book it comes with cover to cover. At which point I realized that anything beyond G readings and timing were useless numbers in my mind.

 

Yea I agree with you on a lot of points there. The horsepower/tq thing does seem to be pretty useless. I guess it would only be helpful if others that have the same system and fairly same mods used it as well so you had something to compare too.

Ahh well it's fun to play with. When I go to the track this spring I'll bring it along and compare the results of the two.

 

+1 on the HP and TQ numbers being about as accurate as a blind man throwing darts.

For giggles once, I ran mine while at Atco raceway. ET's where pretty close... usually + or - about 1 tenth, tho bad launches tended to give as much a 3 tenths... MPH was slightly higher also, but I think thats because it reads actual MPH while the track uses an average over the last few feet.

 

+1 to all that. You already have one, so you'll enjoy it, but best thing to do, find a buddy that has one, and borrow it for a few weeks and take it to the track a few times. Then just borrow it when you make a major mod to see the changes. I haven't used mine in quit a while. Can't get enough traction to get a good reading anyway without some DRs or slicks.

I took mine to the track a few times. Reading was always within .1 of the track and mph a little higher since the track averages the last 60 feet.

 

Noice! Well I will be the friend for guys to borrow it from hahaha. It would be cool to see what it says in a few different platforms.
