Emerald ECU not connecting to PC

[Chris Norman]

Early version of Emerald ECU (M3D) will not stay connected to my laptop.

 

I have the correct Emerald software (later versions detect an earlier ECU and give appropriate error message) and have previously connected the laptop to read/write maps (.fig type) I offered a copy of my map to a fellow BC'er but when trying to connect to download from the ECU I get the following message in the bottom right hand corner of the Emerald software opening window

 

Status - ECU connected

then (in red)

Status - No ECU link

 

above messages alternate in a random pattern and the laptop cannot read the map ☹️

 

I have also inspected and tested the connection lead which appers to be OK and the 7 runs fine.

 

Any ideas anyone?

 

Thanks

Chris

Presumably you are using a USB to serial converter?

 

If so, what make and model?

[Chris Norman]

Hi Jingars,

 

Connection is via serial lead no USB adaptor - older laptop with serial port on COM1

 

Thanks

Chris

Sounds like the lead, can you borrow one from someone to try it out?

[Chris Norman]

Hi alan7,This did cross my mind although I did check the lead for continuity but definitely no harm in trying an alternative.

 

I was concerned the error message was an emerald default advising the ecu is malfunctioning.

 

Anyone in the Woking area with an emerald lead who would not mind me visiting them for 5 minutes to check

 

If it is the lead I can then source a replacement

 

Thanks

Chris
