Why no CAN ?

[VEMS]

Hello Mangoo,

I have a Dash 2 that I would like to get up and working with my Vems.
Race Technology serial interface for vems is of no use  ( just gives random numbers)

What part is not working of your Race Technology interface, i have used these before (personally) without problems, are you sure you have enabled aim mode on the v3 ?

Best regards, Dave

Hi,

When I enable aim I get static data on  the channels selected and they do not correspond to the real values.


When aim is un-checked I get no data at all.

In this moment the engine is running with 65 C water temp and 1000 rpm




Edit:
Might be best to cut my part out of this thread

Some news about this?

as I remember race technology needs to be reflashed to display values correctly

[magoo]

which part of  RT  gadgets needs re-flashing?

The RS232 adapter or the dash2 itself?

dash2 but I may be wrong :)

Hello all,

That's my first post here, as I had troubles registering ever since I got into the VEMS world. I have been continously posting on the WiKi (josephbmw).

The absence of CAN is in fact a real back off for VEMS, especially in cars like BMWs & VWs & the list goes on.

The only solution I came up with was integrating an Arduino with a CAN bus shield, I was busy lately so I am starting the project. I do want to read the stream directly from the VEMS (possibility in AiM) then let the Arduino broadcast it to the CAN bus.
Problems am looking to solve:
* RPM, coolant, consumption gauges that need a CAN signal & doesn't work since I VEMSed the car
* Get the AC to work since the compressor activation on BMWs is sent from the cluster to the ECU, especially with the new firmware supporting it (am waiting for the 1.2.33 to be available ever since I saw the config)

Speaking about that, the only documents I have about AiM suggests it is a CAN protocol of some sort, am trying to collect the missing pieces

That's in brief, excuse me for any language/typing mistakes, am on the go

An auxiliary device will be available soon that will have CAN output from VEMS.
How deep it will be I don´t know, but it will be an excellent solution

Soon, soon, soon  >:(

any progress with the arduino/can bus  coding?

It looks like we're getting closer to an official CAN BUS solution!

Just seen that there is a FW update for a test vehicle (BMW M5) where they are controlling the IAC and ETC throttle via CAN BUS (not H-bridge driver addon).

Pretty exciting!

Its the 4.0L M3 V8 engine, but yes a CAN solution is big news.

[1.2.34] - experimental, only for testing
BMW S65 CAN-bus controlled IAC and ETC (DBW electronic throttle)
needs SPI-bus CAN addon module
(unlike the dummy throttle) bridgeoutput driver not needed (controlled via CAN-twisted-pair, terminated bus) love it.

Where can you stay updated with this topic in the wiki? Would be fun to follow the updates on this!

TIL there is a FB VEM user group  ???
