Looking for CANbus data captures for aftermarket ECUs.
Posted by Existing-Summer-4878@reddit | projectcar | View on Reddit | 12 comments
I’m working on an aftermarket digital dash project (powergaugepro.com) and I’m trying to add support for more standalone ECUs.
We have access to CAN/DBC documentation, but to properly test our dash we need real be CAN bus captures from actual vehicles. The goal is to replay the data and make sure our dash interprets RPM, temps, pressures, sensor values, warnings, etc. correctly.
If anyone has a Holley, Haltech, ECU Master, MaxxECU, Link, AEM, MoTeC, FuelTech, MegaSquirt, Emtron, Syvecs, or similar ECU and can share a CAN log, it would be a huge help.
The main things I’d need with the file are the ECU brand/model, firmware/software version, and a quick note about what was happening during the capture, such as key-on, idle, revving, or driving.
Thanks, I’d really appreciate any help.
Thanks,
-Chris

Does anyone know about converting my haltech to all analog gauges? I want to make an 80s themed space ship in my Celica.

Real can logs are harder to find than people expect. most ecu makers have sim modes but they don't match real sensor noise. might be easier reaching out to shops that tune on these platforms daily, Dynosty runs a Haltech PnP setup on VQs and probaly has live logs.

I can help. I just started driving/ tuning my 2JZ swapped Datsun Z on an ECUmaster EMU Black. @blokgarage on youtube and Instagram. Send me a message.

"Develop my product for me for free"
Common man, really?

I mean, they're just asking for log files so they can test their product. I don't think this is an insane ask from a small company. You don't have to share a log file of you don't want to.

Offering nothing in return is seen as bad form. I work in product development and most of us look down on this

How much is this expected to cost?

Targeting $1500. But we havnt finalized that yet.

I mean, have you started with the official documentation for these units?
Here are the default messages for Megasquirt.

We already have the dbc files, and we can randomly generate frames. But I want to replay an actual data stream to validate against as a real world example. Belt and suspenders.. write the software and config, and validate it works against real data. Alternative way is to literally buy every ECU out there and set them up on an engine stim. I’m hoping to make this a little less painful :)

Aren’t most can bus IDs and values published for the respective vendors?

Yeah we have the dbc files (which describes the format of the frames), but we want to run some real data through the software for each ECU to validate it works. I’m not asking for data about the ECU which I can get from the vendors download site or datasheets. I’m asking for a real example data stream I can play back to validate our canbus config properly works for a given ECU.
