Firstly, brilliant app and even better support from what I've read in the forums. Bravo!
I went to the track recently and used a trial of RC Pro and I was extremely impressed - safe to say I'll be purchasing this shortly. I performed a manual import of video (Captured on GoPro HERO) then export with overlay - loved it but did find the manual sync a little tricky on such a tiny screen on my phone.
My question is - I have an aftermarket ECU (Link G4) and I want to overlay some of the data captured by my ECU - these might be factory sensors like TPS for example, or an analog or digital input that's been wiring into the Link ECU expansion slots, e.g. an aftermarket oil pressure sensor. Is this possible and how?
My ECU supports serial protocol (and CAN shortly too) and I have some cabling allowing me to patch my phone (Samsung) directly to the ECU to read run-time data with the RealDash application for example. Would it be possible to have RC running and my phone connected to my ECU to read the data the data that way instead of using my OBDII port? I think my OBDII port is invalid now that I run an aftermarket ECU.
Thanks for an awesome app
We use Linkecu Atom with RC via Bluetooth obd dongle, as you can wire an Obd2 port to the can-bus of linkecu.
Not sure however if G4 Is supported, or was it from G4+ onwards.
G4 can be sent away for a free hardware upgrade i.e. adding the CANBus port to the board - I'm looking forward to doing this and getting RC working wirelessly.
The Atom doesn't have the dedicated can-bus port on it either. It has the can-bus on the wiring loom connector, doesn't the G4 have it? We've just wired the other end of a obd2 extension cable to the wiring loom connector.
I have a Link G4+ that i can't get to communicate with Racechrono. I'll give some details below, but if anyone can give me some things to try, that would be greatly appreciated. I have a race event in 10 days, and i'd love to get this working.
I'm using a generic ELM327 bluetooth dongle, which worked with Racechrono and my factory ECU no problems at all. I've recently upgraded to the Link ECU which sends OBD-II over CAN (On Board Diagnostics ISO 15764). I'm able to use my dongle and get data with other apps like Torque Pro and Realdash with no problem...only Racechrono will not show data.
Oh, I've tried two different devices. 1, my Nexus 7 tablet. 2, My Samsung S7 with the latest version of Racechrono.
What can I try or what info do you need to help me fault find the reason that Racechrono won't retrieve data?
However, still no go. I tried all four ISO 15764 protocols and it wouldn't transfer.
Here's what I can tell you from the Link settings
Bit rate = 500kbit/s
OBD = ISO 15764-4
Protocol Profiles 6 or 7 should work. I'll paste an output of the device output log of the two different profiles shortly.
These are the commands that get's sent within my RealDash OBD communication file.
Is it possible that one of these is the reason that it works with my ECU? If so, which commands should I add within RaceChrono?
Device output logs attached.
a = profile set to automatic
6 = profile 6 (500kbaud 11bit id)
7 = profile 7 (500kbaud 29bit id)
Maybe consider one of the proper ones from my recommendations: https://racechrono.com/article/faq/which-obd-ii-adapter-should-i-buy
Ah bugger. Ok at least I know it's not a comms problem with the ECU.
I have already ordered an OBDLink LX, I'm just concerned it won't arrive in time for race day.
Thank you for all your help @aol .
