Well I will start by saying the program is worth every bit of the 13 bux it costs. Now the reason I made a topic for it is it is saying I am getting 193 hp at the wheels. I have a 99.5 2.8 quattro 5 speed is that number correct? I thought it was 190 flywheel hp.

 

That's not right. You'll never get that to the wheels on a stock 2.8. And you're right, it's a 190 hp engine.

So...maybe not.

 

Its funny, a friend of mine bought that for his iPhone and we couldn't get it to work very well. It took forever to "calibrate" and then was telling us that my car had a whopping 14HP and his tC had 48HP. Glad you got it to sort of work though.

 

I still think its worth it cuz it seems pretty accurate for 1/4 mile times. Also it figures hp by the weight of the car i think so I should really weigh the car w/ me in it to be accurate.

 

Some guys on AZ got it to work fine after you put some #'s in for trac loss. For $13's can't be too bad

 

it was pretty accurate for my car it's important to give the correct values for your car otherwise it will be off but when I put in 25% for drivetrain and 3400lbs for my a4 with a full tank of gas I ended up with 179hp which is only 9 more than what the awd dyno I put the car on scored. the dyno was pre fmic so you figure that's fairly accurate readings. as long as your weight and drivetrain figures are correct the gps system is good enough so that it's possible to recieve accurate readings for any car.

 

GPS? it doesn't use GPS. It rely's only on the internal accelerometer.
