ECU tuning

Hi this is a very specific question but I bought an openport 2.0 from tactrix for my lancer ralliart 2006 and was hoping to learn about ECU tuning but when I'm trying to collect the current ECU map with ECUflash the following message appear:

[17:01:05.175] -- unlocking ECU --

[17:01:05.175] starting session...

[17:01:06.199] requesting seed...

[17:01:07.214] ECU memory read failure.

[17:01:07.214] interface close

[17:01:07.216] interface close

my ECU number is 1860A420 and I was trying with the mitsucan mitsubooloader M32176F4
