I have just bought a second hand microtech LT-8 ecu for my blacktop 20valve. I understand the fact that because it is second hand that may mean that the ecu has been set to the first motor it was set to and will only run to that motor unless you send it back to microtech bla bla my question is my ecu was previously set to another blacktop 20valve , does that mean it will work on my blacktop 20valve seeing as they r the exact same motors both out of a ae111????
