Thread: Nano Issue after map upload

Has anyone had this issue? I bought a nanocom and a nnn ecu.As the one I had was a msb. Anyhow I uploaded the new map all works great, scrolled through all the menus and had a fiddle. Not sure what I have done but now when I turn the key on I get 6 beeps. The car still starts and runs great. Hopefully someone has also had this issue.
cheers
