great!!!! keep us updated!
Have gotten the revsion 3 BlueCAN PCBs I ordered.
One major over sight tho, I forgot to put mounting holes in the board but thats the reason you make prototypes but will still work perfectly for testing my trace routing to make sure theres no noise interference, Then work on a revision 4.
Update: A08
Switched code over to my Core DAT engine to match my SCANTool plugin.
Settings Page for BlueCANs internal settings for registered versions.
Added min version of YourDyno Check.
The point in this plugin is to work with CAN devices (nodes).
Use the link for distrubuters and find your closest dealer. Just picking one at random in USA it comes to $275.
Then youd get 8 of those ali-express sensors. Maybe MjPower can get cheaper price on it.
The next cheapest option looks to be around the $600 mark for EGT controllers, Using one on a 0-5v scale your going to lose a lot of accuracy or range depending on the converter. Or you could build your own EGT controller with an Arduino.
mm ok! how much cost it? i know ecumaster isnt cheap! maybe trying with K-type to Voltage converter?
Those are the type of sensors it will work with. But you need the CAN Bus Node,(It controls the sensors and turns it into data sent onto a CAN Bus like how you have a controller for your wideband O2 sensor).
Im not sure where MjPower bought it from, He is the one that sent me it.
But here is there website.
https://www.ecumaster.com/products/egt-to-can/
So you could follow there distributors list.
Ok! where do you get EGT sensors?
1X 1K resistor
1X 2K resistor
To drop the TX from the nano to safe level for HC-05 as seen in my wiring diagram.
A breadboard and set of male and female duepoint wires will make hooking everything up together easier.
Then powering it you have a few choices.
Either power from USB using something like 12V ciggy adapter.
Hook directly into ECU 5V and connect to 5V pin
Or use the 7-16V input pin (Just note not all Nano's are made equally in regard to this input pin, The offical spec says 6-20V min/max. But with all the chinese clones and such out there some only do 6-12V which wont work on a car since it will go up to 15V with a alternator running)
When you have all the parts together send me a PM and ill get you a copy of the latest firmware to upload onto it.
Havnt posted a version of firmware on here yet since its changing a lot day to day.
Then ofcourse you need some CAN Nodes to connect to it or a Supported ECU that outputs CAN messages.
Nice! im looking for buy parts and test here, what do i exactly need? only this?
Arduino Nano R 3.0, MCP2515 Canbus adapter, HC-05 Bluetooth adapter.
If your running CANBus at 1000kbps you can use up to 30 nodes.
So can add as many sensors as you want with in that limit.
For example
"ECUMaster EGT CAN adapter" uses 2 nodes for 8 EGT sensors.
Then you could use 4X "14point7 Spartan 3s or Link CAN Lambda".
And still have room for 24 other CAN Bus sensors.
Im adding sensors as people request.
Its easist to add support for them if I get sent one to write support with. But it can be done just using debug log and lots of your time testing builds and changes as MjPower found out with adding support for EMUBlack.
amazing! how do you connect 4 EGT sensors? any possibility for connect 4 widebands too?
Had full day of testing the noise filtering and rate control for the bluetooth part with an engine on the bench dyno.
Worked perfectly even placed right next to the ignition coil.
Couldnt really show too much in the video since it was during working hours.

PCB revision 3.

Quite like the look of this design so sent off for 5 board to get made to use for testing to see how well the analoug inputs fare with them passing next to the 5V trace for the MCP2515.
