Works as a charm, only issue I'm having is with the time update unable to get the weather.
I think something is wrong, it shows my 216cv on 1.9cdti
I'll adjust my rating when this app is updated to support 5th gear inputs. The Gen2 F150 has the 10-speed automatic transmission and dyno pulls are done in 5th gear. Please add this ASAP.
Totally inaccurate. Waste of money pleade return my 10$ . I did everything it asked me to do and so so inacurate . You just took my money. Plesse refund me fully
Tried this app because of the developers efforts. Wanted to see gearing and rpm calculation applied to an HP app. So far so good. The option for entering weather manually is good for stopping extra weather updates.
Dont work many ads
It's simple. Calibration may take couple tries if you do it wrong. I guess calibration pictures in the app could benefit from written words what's up and down, front and back. One of the pictures can be a bit of a guess. After that? You put the data, ACCURATELY. Stop the car, have the phone secure at acceptable position. Which is easiest thing in the world to do. You get green light, you drive. And results shown are very accurate, I've tested it on plenty of cars. Great app.
Had high hope for this app. It is very detailed and the configuration for you car is very technical and specific which I like alot. After I went through the calibration and car set up I could not dyno my car even on a smooth road because my sport springs are to stiff and the app gives an error message because of this. I will not change my race suspension for this to work properly. I will request a refund. It is a good app for a Lincoln Town Car.
App doesnt even have my car version. Cant even use the app at all😤 PSA for those looking at this app, it took customer support 8 months to reply to the original comment before the emoji. I POSTED THIS SEPTEMBER OF 2019 My rating will not change thanks. This is a true testament to the quality of the product free or not. Reply 2.0: just so your aware your rating on Play Store should be your concern not someone that deleted your garage app 8 months ago. I use Force OBD2 now.
Calibration is impossible, wasting my time after 15 unsucessfuly calibration
