Sorry folk but i have practically spend all day this Sunday mooching about tinternet for an NSR and it has begged more questions than it answered.

Can somebody explain the mysterious HRC 010, 020 and 030 cards and why they are so difficult to de restrict ... Surely an engine is an engine so we are talking about the ECU specifically.

So why cant a loom and ecu off say an mc21 not work wonders or an i simplyfying this too much ....
