Makes sense, looks like we need an update alteration to 29. Thanks for your inputs on this!
Alright, getting closer…
RealDash-v263-prerel5-2.apk in same Dropbox link that I sent you over the email.
Works a treat thanks for spending the time to sort that out ![]()
I can remove my standalone temperature gauge now
No, thank you for helping out. These sort of things are next to impossible to solve without help and actual ECU running on the car.
Ah I missed this reply. Just downloaded the new version and tried it. Absolutely amazing . This really moves my project on. Thank you so much !
I’ve moved on with testing and am noting fuel pressure isn’t displayed. Do I just request the same info from ME as before ?
Yes, same thing. We would need to know the ID, and the units that pressure is coming in (kpa, bar, psi …)
Hi, the ID is 38 and I can see the value in psi on meite
prerel7 APK in same location as before.
Unfortunately that has not worked this time . Guess I need to check with ME on the id 38 ?
Did you get any value for fuel pressure, or did it remain at 0?
No value. It was just showing zero pressure ( I do see expected values ok in Meite )
ME looked at my screenshots and have asked that we try 37 instead. Can you arrange please?
RealDash-v263-prerel8.apk in same location. Fuel Pressure is now read from ID37 and assumed to come in as PSI.
Well, It’s now showing a value but not fuel pressure. It’s showing a constant and never changing value of 72.5 - I’ve referred back to ME
Gauges in dashboard may cap the value, to see the actual value that is coming from ECU:
- Go to Settings->Application->Debug
- Tap on ‘Debug Data View’ and browse engine data
I just raised the cap and now i see the real data. What it’s showing is fuel pressure in Kpa.
I did say Psi earlier as that’s what i saw in Meite BUT if I change Meite pressure units to Kpa… The fuel pressure in realdash matches he fuel pressure in Meite.
So… next step … can you make this Kpa value appear as psi in realdash?
Currently RealDash reads ID37 and converts the value from PSI to BAR. RealDash always handles all values internally in Metric units, and does the user unit conversion at the UI stage.
Do you think what ECU is sending is always kPA for fuel pressure? You can calculate the original value by observing it in Debug Data View and multiplying it by 14,5037738.
Now if value changes when units are changed in Meite, this will be difficult to make work right. RealDash receives a pressure value but has no way to know what units are currently active in Meite.
These numbers are a little rough as they are live so they move up and down slightly.
So, I switch on ignition and let the fuel pump prime and can see the following
Fuel pressure value in Back from DED dash = 228.4
Fuel Pressure in Debug = 17.8
I’m probably more confused now
** Edit - In the end - If a value in Kpa or something else is the best we can do it’ll be ok
17.8 * 14.503 (PSI) gives 258.15. Is that correct pressure in kPA?
