I'm wondering if the power fc has a CAN protocol or RS232 Serial Protocol output stream that I could connect to a 3rd party data-logger such as AiM MXL's data-logging device.

- I know that the AEM Plug&Play EMS 30-1800 supports that ability (with an RS232 Serial Protocol) but I havnt been able to find any information on the Power FC regarding this

I would like to know also.

Need the stream for AIM

There is a stream that goes to the handheld controller

Someone posted about how it works a long time ago.
GO SEARCH this forum.

Sorry can't find it.

I searched too and couldnt find it... thats why I started the thread.....

I emailed AIM and they phone Apexi..... and the deal is that Apexi doesnt have a data output stream that can allow for this.

i emailed that aussi company that does the power datalogit and they said it would be a good thing to be able to support AIM or other external race data loggers and guages. that said, are they going to do it? probably not.

so anyone that knows how to do this would be very handy....

....the other option is that anyone with a race data logger goes out and buys the AEM ecu....that computer supports all data loggers but that would totally defeat the benifit of the power fc

I just did a successful search on this PFC forum.
I used one of the words in the first 10 of you initial post.

The reason I don't give direct answers to many questions on these forums:
some questions have answers too easy to find, and or some people need to learn how to analyze and diagnose problems.

So that is why you put up 3 post about searching ?
Now this is becoming a "off topic" topic.

I will try to get in contact with AIM and find out what they need to know about the data stream

Glutton,

With Datalogit we can use the RS232 output.

Here is more information about it.

thanks for the link! .... its a really good thread, unforutnatly for us its not terribly helpful for what we need (unless i missed something). Most (i say because i may have missed) of the thread is dedicated to the digital output from the datalogit device so you can read it on a digital platform. in the datalogit device itself it takes the signal from the powerfc in an analog format and converts it to a digital signal under this rs232 protocol... what we need is more like.... an analog output with the proper connection pins or another digital/analog converter, again with the right connection pins. In this thread there was around 3 posts which asked if there was something like this but they wernt replied to.

fortunatly there was talk of a palmsolution device which could be benificial for us and it can be found at http://www.emicros.com/i2c232.htm
... the question is though, can the AiM or Pi dataloggers read the informaiton comming from this conversion because $89 is somethign you just want to throw away on a useless electrical part.


** added in edit** the rs232 protocol is just a standard transmission of data, in this case in a serial format. the data loggers need this type of protocol in order to process the information comming from the ecu - but they can also work on CAN protocols as well. Now, since the ecu uses these protocols (they all do, so there wasnt much of a quesiton of if the ecu uses this protocol or not) theres no need for a conversion from another protocol into the ones read by the dataloggers - its the acutal connection and reading of the informaiton transmitted that is the problem..... wierd things happen sometimes if you have too many converters in your electical system.
** end of edit**



crewrx7r1, I woudlnt have posted the thread if I hadnt looked before..... i just did the same search with the "first 10 words in my original post" and found nothing useful.... if you read further than my first 10 words you would have found (if you understood.....) that the AiM and Pi dataloggers are all analog readers with no digital interface between the ecu and the datalogger - look at the back of the AEM ecu and you'll see a bunch of pins, look at the power fc and you wont...... so, thanks for your imput but no one likes a smartass....

The signal from the power FC to the datalogit is a digital signal. (not RS232)

I can not find any information about this protocol.

The RS232 output from datalogit you can use with AIM XML displays.
They have a digital input for RS232
This ECUs are allready in there list

AEM EMS - All
AiM - RS232
Autronic - SM2_V190/191

Now we just need to find a way to read the datalogit with the AIM
I think the best way is with the datalogit box so you can still use the commander.

ahh, i was under the impression that the signlan to datalogit was analog.. thx for correcting me.


looking though the datalogit website I cant find what kind of protocol they use... but if its I2C then we could possibly use the converter i mentioned in my previous post.
I just emailed FC Datalogit to make sure what output protocols the datalogit box uses, hopefully i get a responce back. Then we can find a proper converter and test it out.

That is the one.

jeroentje.nl

The Data output from the datalogit is RS232
This is the protocol

We need to know the bit sequence.
So a start bit.... some bits who tell what sensor we are looking at.. then some bits with what the sensor is reading. and then a stop bit.
Then we also need to know what the min. and max. bit is for each sensor.

That is what is in the topic.

Now i wish there was a easy to use list with what bit sequence is for what sensor output

Some gues overhere know.
like fasthatch and ky7
The FCWatch program uses the RS232 port to read all data and plot some gauges on your screen.

glutton

i dont have any electircal engineering background but do you or anyoene else know how we could make the connectino to the AiM datalogger? hopefully there is a piece of hardware to do it but we could always just run the information from the datalogit to a laptop then to the AiM digital display & logger ... i think theres cables that can go to usb - serial bus - the AiM link up.

jeroentje.nl

The connection itself is no problem

Use the Power FC with the datalogit box.
Then you still can use the commander.

AIM XML is connected to the RS232 connector of the datalogit box.
That is very easy to do.

But now need the AIM to understand the data that the datalogit box is giving him.

I'm contacting datalogit about it.
