Doesn’t work for 0-60 on Aston Martin

Doesn’t work, don’t waste time

Setting Ignition Timing

Great help setting the ignition timing fir my 60 year old Austin Healey.

It’s ok

Used to be good but stopped being accurate, also you can’t purchase qmt

Doesn’t even have my car?

I have a Tesla Model Y Performance and they don’t have an option for that. It’s funny that it makes you even choose a car? like why?

It’s funny because they have the option for a Model 3, Model S and X and even a cybertruck?? like seriously? the worst tesla is on there? But not the most sold one?

Low accuracy

It did not say I hit 60 mph until I was at >75 mph. Don’t trust the accuracy

Don’t trust this app

Went to test my Porsche after doing a ECU stage 1 and TCU stage 1. The numbers are exactly the same before the Flash. I can sense way more speed and way more toeque. But this app does nothing that presenting the std info that you can find in a magazine.

Horrible app

I have tuned 06 mustang, Press gas and a get 60 and app only after 3 seconds show me 60mph when a I already had 100mph, so inaccurate

No gps start.

You have to manually hit start and wait for the count down to hit zero. Other apps have gps start which is a more useful feature.

Love the app except….

Loving the app and am thinking of purchasing to get all features. The main thing holding me back is some parts of the app are not fully working. Like registering my account to login. Also it’s not saving some setting. That may be fixed when logged in but it won’t let me. For that reason I am giving only 3 stars.

Instructions

I just tried to test my times, but couldn’t figure it out. It says it is “hands free”, but mine has a start button. It’s kind of annoying to have to manually start the timer and get the car running at the same time. Then it said that I have to record my times, but I don’t see a way to do that. Ideas? Instructions would be helpful.

Innacurate

Getting 5.05 0-60 on Audi S4 (after remap) when dyno says 3.6 and plug in diagnostics 0-60 says 3.8

Terrible, doesn’t function

Don’t even bother downloading lol. Tried to see if I could use it for my built bmw 535i, but it only brings you to the loading screen that says “select vehicle” then tells you there’s a network issue no matter what you try. Honestly don’t wast your time, I tried with Wi-Fi and without. Neither worked it just keeps you on the same screen telling you there is an issue with network connection. It’s a completely useless app. 👎🏼(I read and other people had this exact same issue I’m having, so it must be common)

Bahahah

This app no where even close its very unaccurate

It doesn’t load

When you try to log in thru Facebook it just buffers.
When you try and use the app not logged in it doesn’t work either.

Problem

I installed aplication and I can’t select vehicle „Couldn’t connect to network; Please verify your network connection, tap ok to try again”. I tried uninstall and install again but this not working

Few bugs?

Leaderboard doesn’t work

Facebook connection

Will not let me connect my Facebook to the app even after uninstalling and reinstalling

Speedometer matched

I was shocked to see how accurate the speed readings were compared to my speedometer, off by a bit when accelerating fast but that’s a given with gps. Fun app, well designed.

Trash

Deleted it minutes after installing due to the app not connecting to my network. CRAP!

Garbage app!

Don’t waste your time and gas trying to get a 0-60 time on this app. It doesn’t work!
