ElanScan is a piece of software which interfaces with the Elan's ECU and can retrieve various real-time stats.
ElanScan is available for download from [ESM's website], information on obtaining suitable interfaces is available at [GeoffSmith's website].

Preparation
If you think you have a problem, CHECK THE BASE TIMING. Provided this is correct, then proceed.
Communication errors
The error log reports any bad communications between the pc/ES and then car/ECU :
Comm port inactive
The wrong communications port has been selected for ElanScan. Check in the pc hardware configuration / device manager to see which ports are present. {From bitter experience, this may also indicate a broken serial port!} In Windows XP go into Device Manager: Right mouse on | My Computer | and select | Properties |, select the | Hardware | tab and press | Device Manager |. Expand the | Universal Serial Bus controllers | by clicking on the [+] and there should be a reference to a | USB serial converter |. Expand the | Ports (Com & LPT) | and there should be a reference to | USB Serial Port (COMX) |. This port number must be used so in ElanScan click "Setup" then "Set comm port" and select the correct number (COMX) from the list.
Bad echo (sent: F4 56 01 B5: received: )
The ECU is not responding, usually because the ignition is not turned on or the interfaces is not properly connected [Note F4 56 01 B5 relates to the Elan turbo engine only]
Bad echo (sent: F4 56 01 B5: received: XX XX XX XX)
Indicates noisy communication with the ECU, likely caused by a poor electrical connection [Note XX is the hex representation of a byte of data and there may be between one and four bytes returned depending on the problem]
No reply No frame start byte received
Probably caused by having the latency timer setting too high: In device manager (see "Comm port inactive" above), select | USB serial port | Port settings | Advanced | BM option:Latency timer (ms) | and make sure it is set to 1. See also USB driver instructions.
