PID Conversion from ScanGauge to RaceChrono

Hi all,

I've got a ScanGauge 3 that I can monitor Engine Oil Temperature with (car is a 2017 Fiat 124 Spider Abarth), and am looking to see if there's anyway I can translate the info I have from ScanGauge into something RaceChrono can read and display. Here's what I have from ScanGauge for Oil Temperature:

DESCRIPTION: Variable Valve Actuator Oil Temperature (°F)​
TXD: 07E022704B​
RXF: C4620570364B​
RXD: 3010​
MTH: 00090050FFD8​
NAME: VVA

Using an app called ScanGauge 2 OBDdash PID, it translated the above to this:

Long Name: VVA Oil Temp
Short name: VVA
ECU Address: 7E0
Service Mode: 22
Parameter ID: 704B
Expression:
(A*256+B)*9/80-40

I tried a couple different things in RaceChrono, but nothing seems to work, so if anyone out there has any ideas, I'd really appreciate any and all help. Thanks!

  • So update on things I've tried:

    - With the OBD2 header, I set it to 0x7E0, set PID to 0x704B, and equation (A*256+B)*9/80-40, couldn't even save the custom PID.
    - I changed the PID to 0x22704B and I was able to actually save the PID, but still no data.
    - I next tried changing the equation to BytesToUInt(raw,0,1)+ -40, but still no data.
    - Tried changing the OBD2 header to 0x7DF, still no data.

    I thought the first one would work based on how the FRS scangauge settings translated to Racechrono, but it doesn't seem to like it. I'll still keep trying different things, but if anyone else has some ideas, I'm all ears. For what it's worth, the PIDs for the ND2 (tire pressure, brake position, accelerator position) all worked great, just oil temperature isn't cooperating lol.

    0x22704B sounds about right for a PID. There will be a result independent from the equation, a configuration with header and PID will give a result when correct. Unfortunately I'm not able to help further.
  • Hmm... if that's the case, I won't mess with the equation too much then and focus on trying to get a PID/Header combo that actually works. Back to the drawing board lol...
