#18868 Low power at start

Don't know if this is a wrong setting but at the start of the race after the 5 lights go out the cars barely respond to the throttle input then roughly 2 seconds later the throttle acts normally.

As you can imagine this results in a lot of crashes, especially with kids, as they go full throttle in those first seconds when the cars are not very responsive.

You're actually the second person reporting this. I'm not sure whats the cause yet. Could you please send me a support request from within the app (main menu > help & support > request support) so I can see some data of your SmartRace instance? Thanks!

Haven't had the same issue in Free practice or Qualify mode

No change however I think the issue could be because of the option I have highlighted because moving this slider increased the reduced power duration

Hm, thats so strange. Whatever I do, I can't reproduce this. Would you have the chance to record a video showing how you connect to the track until the issue happens step by step? That would be very helpful.

I too am seeing this only in race mode. After much investigating I found that if you change the fuel setting to 100% when car runs out of fuel you will get full power at start of race. However anything below that you have no power, and when throttle profile of most conservative is on anthing less that than 100 your car will not move. If you leave it set at 100 though when car runs out of fuel there is no low fuel affect and does not revert to car calibration for low speed. It seems to me that the car is not registering correclty until it crosses the start line and then registers fuel as full and you then recieve your full power after about 1-2 seconds. I also tried the VCS as i thought the same thing but resulted in no change. Only change that made it work is the fuel power when out of fuel. I tried to upload a video of it however it will not upload for some reason.

Just tried that and it has stopped the issue for me

Interesting findings @madkat_hobbies - I'll check this

I added code to make sure every car starts with 100% fuel tank at the beginning of a new event. This "SHOULD" fix the issue. Please test this once version 2.0.1 is available (should be today or tomorrow) and feel free to re-open if this still happens. Thanks!

That seems to have fixed it๐Ÿ‘

We noticed during club racing night that if you hit repeat race it reverts back to the issue but if you hit new race there were no issues.

Thanks, I'll look into it

Thanks to input from different users, I was finally able to track this issue down. In the end, it came down to a single character in the source code:

Before the fix: app.fuel.current_fuel_get(controller_id) == 0
After the fix: app.fuel.current_fuel_get(controller_id) === 0

Thanks JavaScript ๐Ÿ˜บ

This is issue will be fixed in 2.0.2 which will be available later today or early tomorrow.

Thanks for your patience!

Cheers,
Marc
