Right here goes
As my other post dont seem to be having much luck
Got a dash2 and dl1 last week new , plugged it all in serial cable wise to my Autronic smc ecu ,connected only the 4 menu buttons and 12v 0v but only seems to be working on gps readings only, no ecu communication.
As my other thread the dash shift lights are flashing all the time as well, wether thats anything to do with , I dont know
As anyone any advice?
Or am i daft
Cheers Adam

Hi Adam,
Can you please email me directly, mhill at race-technology.com and explain to me exactly how you have connected the DASH2 and DL1 to your ECU. There is no mention of an ECU interface in the connections. You will need an ECU interface in there which must be powered. You can check that it is getting power by sending commands from the DASH2 to the DL1 (start / stop logging for example). The DL1 will need to be configured to retransmit the received serial data on the serial port. You can test the ECU interface by itself by connecting the output of the ECU interface to a PC and monitoring the data using the lite monitor application.
Regards,
Martin

Might not be relevant, but when I have issues with data communication in test equipment, I try to isolate the problem one step at a time.
Is the DL1 working properly?
Is it outputting serial data properly to the monitor program?
Is the Dash2 working as a standalone device (displaying it's own analog data properly)?
Is your ECU sending out serial data properly to a computer (hyper terminal)?
There is also a "Pulses per rev" setting in the Dash2 setup program. Perhaps that is not correct?

Not sure on some of the answers mate but this is what I know
The speed seems to work on the dash2 from the dl1
The revs work also but from hard wire from my ecu
The gear selector works but not right settings , but close
When I connect my laptop to the ecu I can alter the settings
Not sure about anything else , still getting to grips with it

I read a post a while ago where a support guy asked for a bit of serial data to decode.
Since you can read hardwire RPM, but not serial data, it's either your ECU isn't sending good data or your DL1 isn't decoding it properly.
Can you hook up a laptop to your ECU and read the data stream through hyper-terminal?
