Hey guys.
Been looking at the new gtech as a tool for gauging effects of mods and tune changes. Never really thought much of the older ones, too fidgety and seemed overall to be a bodgy sort of thing. But these new ones have my interest as they combine the g meter with a 10hrtz gps system which is a pretty snappy update speed, can be mounted in any position and record to memory card.
Reading a few writeups and apparently these are very accurate and consistent to within .1 seconds and +/- 2 rwhp if the exact car weight is used and eliminate dyno variations, which is key for measuring performance changes. Dont know if its bullshit but some people reckon with the simulated dyno software they where able to see dips and bumps in the power curves that matched the real dyno printout which apparently was plugs breaking down. I guess if the update resolution was fast enough this could be possible.
What do you's think of these any one using one. Its about three hunge for the rr model which is the schmicko model.

i used to use my flash gtech lots when tuning

i have a gtech r/r but its a apin in the ass to calibrate for every car. if your only doing 1 car its a great tuning tool , obviously anything that gauges an increase or decrease is a good tool , thats all a dyno is after all

i have like 4 cars preloaded ready for tuning them and i also have an app to change the inputted weight on the files once on pc if you have a weight difference
