Most of the dash is straightforward at first glance, but there are some interactive features and logic that aren’t obvious unless you know they’re there, for example:
• Pressing MAP switches to show tyre pressures and vice versa
• Pressing the Toyota logo toggles the media view
• Pressing the TRD logo switches the dash to a red “sport” theme
• Pressing RPM activates launch mode (rev bar flashes, “Launch activated” indicator shows, RPM display changes to launch RPM in red)
• When 2nd gear is selected, launch mode automatically cancels and everything returns to normal
• There is also a custom shift light and some warning logic
I’m mentioning this just so you know the file isn’t only static gauges and some behaviour is hidden behind touch areas and conditions.
The one issue I’m trying to solve is the calculated gear display.
The gear is always correct once a gear is fully engaged. However, during downshifts (especially heel-toe), while the clutch is in and the drivetrain is unloaded, the calculated gear sometimes briefly flashes completely wrong gears (for example 4th or even 5th when going from 3rd to 2nd) before settling on the correct gear.
It does not show N unless stopped. It’s just mis-identifying the gear during the shift because RPM and speed are temporarily in an ambiguous state.
I’ve tried Value Smoothing (even at 100%), but it doesn’t really solve it because the underlying calculated value genuinely jumps to those gears for a short time.
Is there any supported way in RealDash to:
• Only update the displayed gear when the calculated gear has been stable for some time?
• Or hold the last valid gear until the new gear is clearly engaged?
• Or any other recommended approach for manual cars using calculated gear?
I’m completely fine with a small delay in the display if that’s what it takes. I just want to avoid showing obviously wrong gears during shifts.
There is already a 0.25 seconds delay before Calculated Gear input is updated. Actually, I use calculated gear in my DEATHFISH 2, and have found that 0.25s works pretty well for me. Unfortunately delay is hard coded and cannot be changed.
As for Neutral, if neutral safety switch input is not received, N is displayed when speed goes to 0. While its not correct, but without the actual data from the vehicle, its the next best thing. In my car, I have both, neutral safety switch, and reverse switch transferred over CAN and with those, calculated gear works relatively well for me.
Are you connected over OBD2 or CAN connection type? From OBD2 you probably cannot read neutral/reverse status. CAN connection would be faster and we may even find those switches from the data.
Thank you . I’m really pleased how it turned out. It took ages to figure out and build, especially because I’m honestly not great with computers or software, so I had help from ChatGPT with everything .
I’ve wanted a proper race/telemetry style screen in my car for years, but I could never afford a real motorsport dash or anything like that, so RealDash is basically the only reason this was possible for me at all. I genuinely really appreciate you making it.
To answer your question: I’m connected over OBD2 using an OBDLink MX+ dongle. I’d asked you before about some connectivity issues, but I managed to get that sorted in the end — it turned out to be a setting change either in RealDash or in the MX+ app (can’t remember exactly which), and it’s been working perfectly since.
And just to say, the gear behaviour really doesn’t bother me in the grand scheme of things — I totally understand there are always going to be limitations depending on the car and the data available, and I’m still absolutely chuffed with how everything works overall.
I would be more than happy to share the dash with the community if anyone wants to use it I’m just not really sure how to
You can share your dashboard in my.realdash.net. Go to My Dashboards and use the share button to share with everyone or with certain My RealDash users.
I do have Toyota GT86 2012-2021 CAN description file. Using CAN connection would give you faster data rate and access to some data that is not available from OBD2. Let me know if you would be interested of testing the CAN connection with your car.
Okay cool thanks I will look into sharing it on there.
I’m currently using RealDash via OBDlink /MX+ Bluetooth. I noticed the GT86 option in the connections menu but it didn’t seem to change anything with OBD. I’m planning to move to a GJP IO box and use raw CAN in the near future — is that when the GT86 profile becomes relevant?
This is just some images, one of the menu I was describing in my last reply. Also one of the updated dash with the gear shift light and the launch control mode. I have also shared it with public in my realdash. Don’t know if that is the right way to do it so other people can use it or not but hopefully it is.
Sorry I meant to say I’m definitely very interested in testing the GT86 CAN profile for sure. I’m still on OBD at the moment obviously but hoping to get the GJP IO box soon.
