Post Possible to log CAN data on RCP MKI? 
Quick question, is it possible to setup my RCP MKI to log CAN bus data, specifically from a 2007 Rav4 ECU (swapping a 3.5L 2GR-FE into my MR2). Just wondering if I should run the wires or not, will figure out the details later!

Well, after a bit more searching I found the answer, that the MKI can't do CAN without the CANx add-on board. Is that available somewhere, or did it get dropped when the MKII came out?

Alternately, I see a bluetooth module in the MKI Accessories page, but the description says it only works with the MKII. https://www.autosportlabs.com/product-category/race_capture_data_acquisition_telemetry/mk1-parts-and-accessories/

Is it possible to log via that from an OBD2 bluetooth adapter? Seems like a roundabout way to get there...

Can someone at least answer this question? Does the BT module work with the MKI or not?

Hi, Sorry for the delay! Smile

The Bluetooth module does work with MK1 as well as MK2.

We had an initial run of the CANx module that works with the MK1, but we don't have current plans to produce more of them. The hardware design files for this adapter are available here for the DIY-er: https://github.com/autosportlabs/CANx

Hope this helps!

Cool, thanks. I may pick one of those up here soon. I have figured out direct methods to log all of the things I was hoping to log, so the CAN logging isn't an issue any more, but being able to connect from my tablet would be nice!

Thanks for making this info openly available. DIY-er's still need to have the board printed somewhere, right? I'm comfortable with soldering in some thru-hole components, but have no means to print a PCB Sad

Even if you don't produce a finished CANx module, could we purchase a kit or bag of parts Megasquirt style?

Check out OSHPark for cheap/easy PCB jobs. They handle the Eagle files natively. Just upload, pay, and wait a week or so.

Oshpark is perfect for this. The parts are surface mount, but do-able with the right parts and practice. Smile

Cool, thanks for the tip where to get the board made.

What about a components parts list? Maybe I'm missing something as I'm not seeing that at the GitHub link.

Hi,

We've updated the repository to include a BOM and some brief instructions on building and connecting it to MK1.

This could be a great little project for a student or someone familiar with building surface mount circuits, if you're not comfortable doing it yourself.

Keep us posted on how it goes!

Uh oh, fault message on OSH Park Sad

I downloaded the CANx.brd file (save link as) from GitHub and then tried to upload to OSH Park, this was the message which came back.

Sounds like the download was garbled. Try this:

* Go to: https://github.com/autosportlabs/CANx
* Press the green "Clone or Download" button on right
* Select the "Download zip" option.

You'll find the .brd file in there.

Thanks for the nice list of parts in the CANx.csv!

* "MCP2515ST" is this MCP2515-I/ST or MCP2515-E/ST? If E is the same as I, just greater temp then I'd take "E" Razz

* WE-CBF_1812 seems to come in different types. Which MHz, Ohm, and mA are recommended?

* There are a few different voltage ratings for C0603K 0.1uF and 22pF. Which is recommended?

* CPOL-USSMCD doesn't lead directly to a "polarized capacitor." Searching for a 10uF "polarized capacitor" yields results for bi-polar/non-polar and general purpose. Which is correct?

* R-US_R0603 is the 120Ohm terminating resistor. 100mW / 50V? Same question for the 4.7K.

* CRYSTAL5X3 must be CSX3-AA-18-16.000, right?

* MCP2551 has an option for SOIC-8, this is the right one, correct?

* 95001-2881 is obsolete. Is 95501-2881 a suitable replacement?

Yup, doesn't matter. Just needs to be the TSSOP package.

* WE-CBF_1812 seems to come in different types. Which MHz, Ohm, and mA are recommended?

It's a ferrite bead, not critical. If uncertain, just jumper the pad with a wire.

* There are a few different voltage ratings for C0603K 0.1uF and 22pF. Which is recommended?

at least 16v.

* CPOL-USSMCD doesn't lead directly to a "polarized capacitor." Searching for a 10uF "polarized capacitor" yields results for bi-polar/non-polar and general purpose. Which is correct?

you can use a 10uF 1206 ceramic capacitor, 16v. Polarized capacitor not required.

* R-US_R0603 is the 120Ohm terminating resistor. 100mW / 50V? Same question for the 4.7K.

Those specs are fine.

* CRYSTAL5X3 must be CSX3-AA-18-16.000, right?

That should work.

* MCP2551 has an option for SOIC-8, this is the right one, correct?

SOIC-8 is the package, correct.

* 95001-2881 is obsolete. Is 95501-2881 a suitable replacement?

That should work.

Oops, don't need 1000 of those crystals! Embarassed

These are the important specs, right?
Frequency: 16MHz
Series/Package: CSX3

"CSX3" gives only once choice.
So is the Package / Case then 5mm x 3.2mm?
Any particular load capacitance or frequency stability?

Maybe this one? ECS-160-18-30BQ-DS
