In an earlier post you said that the hardware requirements are open port 2.0 + senselock key.

Sorry I'm still very much a noobie. I'll get this stuff quickly, just need a bit more help.

Is open port 2.0 the interface device (ECU to PC hardware)?
And
Senselock key is some sort of key for the PC to make the MMCflash software functional?

You read that right. The only problem may be to find the ECU pinout

The ecu is easily dumped. I managed to be ale to read the ecu and write to the ecu successfully. I've found most of tables and was able to remove boost limit and adjust rev limit. In fact, I also found the table that defines the learner mode limits. I'm looking for a dump of a popular commercial dump to compare my changes. Anyone out there willing to share?
