OK, I can't get this thing to talk with my laptop. Of course being that my laptop is from this decade it has no serial port inputs, just UBS. So I picked up the adapter and have had absolutely NO luck. So, I just tried it on my sons laptop as he does have a serial port, and still can't get this Gtech to communicate with it. Yes, I installed the software. Aaarrrggg.

Any input from those of you who have been successful would be appreciated.

 

I think when i first set mine up I had some questions and their help line was very good. Try giving them a call I think they will help you get it up and running. It is a great little tool once you have it set up.

 

Does it really accurate? Compare to your dyno, does this give you close to the real dyno? I'm really interested.

 

make sure you get the port settings right. I got a Belkin PDA Serial-to-USB connector and that worked. connect it. Make sure you go to "upload to computer" on the gtech and then connect from the program.

hope that helps.

Yes it seems to be very close. I've done 2 runs at the dyno both before and after changes to my mini. First time i took it to the dyno the G-tech read 157whp. While the Dyno read 154whp. on the second trip after installing a 19% pulley. Gtech was at 181whp and the dyno was at 178whp. The G-tech test were done at an old Airport where the road if flat.. if you run it on the Hwy or any road where there are hills, dips, climbs, etc.. the reading can vary alot. +- 10 hp. et's +-1 sec. The idea is to make sure you use the same stretch of road (perferably non-public) to test the car each time and compare the results.

Unforturnatly i cant help you there.. I've hooked mine to a desktop and it worked first time. I did notice from G-Tech's web site there have been many FAQ's on that subject. Along with the RPM pick-up problem

 

Mugami,

Thanks for the information. I think the result should be good enough for me to test my car for each mods I'm planing to add. So that way I can see how much improvement. I think +-3hp is not that bad.

I have seen people dyno the cars on the real machine with the same mods and....even get +-10hp different in return.

 

And note that it was +3 relative to the dyno both times. I would think consistency is more desirable than the absolute number if you're trying to evaluate the effect of various mods. As someone else pointed out, always try to use the same course under the same conditions. And same driver, as well!

 

Has ur Gtech's RPM been off? mine jumps when i am at a stop.

 

Geeesshhh man, I tried hooking this up to three laptops, and once with the assistance of my brother who knows computers, and NOTHING!

I'll call Gtech, but I have the feeling that they can't help much as I already called them once before.



What rpm # did you all end up using when you calibrated it. I found that #18 was best for me.

 

From what i understand the Lighter in the Mini is a regulated power supply and is why were having the pickup problem. By turning on all the lights it seemed to pick up better. Also i do believe it was #18 after i installed the new firmware. The model i have is a First generation G-tech pro. (black casing). I'll see if i cant attach a plot ive done with both Firmwares.
