tach flashing means the idle is too low should be at least 1k rpm. there is also a program "flash" for the ECH available at the dealer to correct the speedo acting stupid. this was a service bulletin from BDM.

If you read your owners manual you will learn that your tach lights flashing is your motor warning you that the rpm is too low. Raise the idle a bit.

For the speedo you need to have your EHC flashed if you have the USB plug on it so that it gets a second start-up after the motor starts.

Many threads here on these two subjects already.
