DCS WTIU Engine out of control

Yes, I've had a couple of runaway engines on the iPhone app with the WTIU wired in Passive Mode. (I now use Fixed Channel 2 because Fixed Channel 1's DCS signal is not as reliable for me. I found this on two WTIU's.)  On the DCS app page with a gear symbol, I set maximum speed to 50.  Nevertheless, I've noticed if I accidentally touch the screen in the upper-left area, just outside the odometer, it takes off to 50!  So now I make extra sure the engine is totally dead before I put the iPhone in a pocket.

The other day running two MTH PS3 diesel engines using android version 14 with MTH app V4.0.1 build 78 when one engines started going super-fast climbing to 100 mph then crashed, the app was unresponsive. Has anyone else experienced this issue? If so what’s the solution?  

WTIU is wired in passive mode. It was wired with power going to WTIU input then terminal block which caused a buzzing sound. (which didn’t sound good) Using MTH Z1000 brick

The app has been locking up needing to be refreshed on the run engine screen while running trains.  

The app is super easy to accidently touch a part of the screen that makes the speedometer go to the max.  I have done it a couple times.  It's not responsive enough in time to stop it.   I always set a max speed limit on every engine when setting it up and then you won't have that issue again.  Honestly, I have no idea why MTH even lets the speedometer go that high to begin with.  No train could run that fast.

Thanks all for the tip. That is a very odd and should never been programed that way. Again Thanks

mine does same, should never been on market with this problem and the lionel transformer problem

Sean’s Trains composed a video that takes a deep dive into the MTH app. Look it up on UTube, it’s an excellent tutorial

Set max  engine speed  to 31 since i running speed is 20 to 26 no more run aways so far and smooth throttle now

Gee, I'm so sorry I didn't buy the WTIU but stuck with my old moldy TIU's...  Actually, I'm not that sorry.

Wish  i had just got my old ones fixed

I use an older iPhone (as an remote!) and had that problem a few times.

Initially the phones display setting was on Zoom larger text.

I noticed when I hit the bell button the engine would race off because my finger would touch the speed dial area.

restoring the display to default cured that problem.

I also set speed limits for all engines just in case.

When the screen is zoomed, the area by the knife point would almost touch causing a speed issue when you only wanted to sound the bell.

I’ve started doing speed limiting to 100 or 110 to increase the space between max speed and the + button. Thats where Ive accidentally hit max speed when I’m trying to adjust 1 smph. Im using an older iPad.
