It's a well known fact that accelerometer based products aren't even CLOSE to being as accurate as a real dyno... I jumped on that bandwagon with my G-Tec... I guess if you could get a really accurate weight of the vehicle it could come close.. That is what the G-tec unit is based on... You input the cars weight w/driver then it runs the numbers through an algorithm to determine the numbers.. There are a few stereo HU's that do this as well... Accurate they are not... you'll get what you pay for...
Quote, originally posted by AKLGT »we have a g-tech rr. it's somewhat accurate, weighed ourselves in the car. $7 at the trucking co. Question though, did you happen to get any idea of the weight accuracy from them ? They usually weigh 50,000lb trucks, not 3000lb cars... That is the problem with them, they absolutely rely on the weight accuracy to be accurate on the reading... so there is quite a bit of flub factor...
