Thread: Nanocom Evolution SD Card not reading

Hiya All

As Paul has correctly stated, cheers Paul, the new methodology we have implimented in pre copying the map file to internal memory and validating it before even appempting to write this to an ECU does indeed seem to have been a very positive move.

As expected, it has moved any SD card iffyness to a stage that any file reading error can be pre detected and so effectively eliminate any associated risk to the ECU during the flashing stage.

However one beta tester of this new methodology has still somehow managed to end up with a non functional ECU.

It may be a problem in our software, his files, his unit or his ECU, and we are working closely with him to try and decode the mystery and learn more, but clearly we need to figure out the problem in this case before we can ratify this new methodology for general release.

This all takes a lot of time and effort, and i can but only hope that you all appreciate and understand this.

Any update on this Colin? I have a new map file ready to go, but waiting on a solution to this problem. Don't want to risk bricking an ECU. Thanks, Tim

The updated firmware was released some time ago if you update your Nanocom you will minimize the possibility of damage to your ECU.
You need to do a search on this forum and follow the advice relating to writing maps.

Main ones in my book are remove the red plug from the ECU while writing
Have a CTEK battery charger or equivalent running in supply mode while the writing is taking place. Your battery needs to be fully charged as well
Also format the sd card in your Nanocom with your computer while it is in your Nanocom and only use fat16
There is also advice from BBS to disable the AS10 Security Alarm while writing.

Yea we pretty much discovered that the problem was not Nanocom Software related just before Christmas and so released this as an upgrade.

Sorry that i did not post this info up about this on this site, but i do have my reasons.
