Re: Need deep tech support (Hardware, Circuit Board)

I'll just jumper the pads and hope for the best. :D

Need deep tech support (Hardware, Circuit Board)

So, I've managed to put my Dash2 into a state that it is non-functional. It seems that a component has given up. I hooked it to 13.1V, and the dash pulled 5amps and shut off. It will not power up now. What is this component? It looks to be a Zenner Diode, but I would rather know for sure before I en...

Re: Dash2 - CAN interface question

Perfect. Thank you.

Seems that it's rounding down, but I am not stressing 1MPH.

You are a superstar. Thanks so much!

Re: Dash2 - CAN interface question

More testing using the Live monitor. Sending 0x64 in the expected location for the CAN stream to the CAN module and viewing the serial stream shows 100 km/h on the live monitor. Connecting the CAN interface to the dash2 with latest firmware shows 223 km/h. Seems something is amiss with the dash deco...

Dash2 - CAN interface question

Hello again, I am revisiting this now that my CAN interface works without hardware problems. Here is the scenario: ECU sends multiple variables for speed: Differential Wheel Speed Vehicle Speed (in MPH) (8 bits, unsigned) Driven Wheel Speed (in MPH) ( 8 bits, unsigned) Non-Driven Wheel Speed (in MPH...

Re: Dash2 Serial Datastream questions

It's fully functional now. I have the complete datastream encoding per the spec. I wish Race Technology implemented the 99 channel though. There are things unavailable that I'd like to see (like Ethanol %) that could be put into that channel and streamed from the ECU through the bridge into the Dash...

Re: Questions regarding the CAN Adapter

The BUS is more than just two nodes. It is within the CAN specification. This is really about getting the proper configuration loaded into the adapter. I have tested all the lines, and I have 12V where 12V is necessary. There are no cross-linked traces. Every decade of my experience tells me that th...

Re: Questions regarding the CAN Adapter

It would be great if someone would give me an address to ship this to and an amount it would cost to either repair it, or diagnose it.

Not having this CAN adapter is killing my project.

Re: Dash2 Serial Datastream questions

Data being 8 bits means that the entirety of byte1 is multiplied by 16777216 (2^24) then added to the entirety of byte2 multiplied by 65536 (2^16) then added to the entirety of byte3 multiplied by 256 (2^8) then that giant number is multiplied by 0.01? This is the correct interpretation the multipl...

Re: Dash2 Serial Datastream questions

Here is my partial encode: double decode::getSpeedInMetersPerSecond(uint8_t id, uint8_t data1, uint8_t data2, uint8_t data3, uint8_t data4, uint8_t data5, uint8_t data6, uint8_t data7, uint8_t data8) { //Float_max is 4294967295 (4U) // 0x102 bits 40 - 47 are wheel speed in MPH. //f(y) = (Speed(m / s...

Re: Dash2 Serial Datastream questions

Just to add,

Here is what I have currently. It is a cobbled-together mess as it stands. It does do some decode from the ProEFI, but I need to clean it up a lot. It's a work in progress and I am open to the idea of collaboration with anyone who is interested.

Re: Dash2 Serial Datastream questions

Cheers for that Colin. I appreciate it. I am using a Teensy 3.6 as a CAN to Dash2 bridge. Running at 180mhz, I can log to SD as well as run the dash. I have some testing done, it was just the lack of consistency that was frustrating me. If I could get the official CAN ECU module working properly, I ...

Re: Dash2 Serial Datastream questions

If your speed output is scaled from 0-255 as a single bit then you Martin To go back to this now that it's spring and the car is in pieces. The statement quoted is logically impossible. A bit cannot represent an integer value of 255. Are those karats meant to be pow() operators? That is, would a pa...

Re: Questions regarding the CAN Adapter

So, this isn't working. I have tested and it has power (+12V), and the serial data looks good. The programming utility just does not communicate. I've tried null modem, straight serial, everything that I can think of. What's the trick here? The entire reason that I bought this dash was that I could ...

Re: Questions regarding the CAN Adapter

Do the Rx and Tx lines need to be crossed? Should I be using a null modem cable rather than a straight through RS232 cable?
