Hi I have a the Link g1 LEM3 ecu that i want to map, but the problem is that i can not get the ecu to connect with the computer. I dont really know if i have the right firmware. I downloaded the LEM V4, LEM V5, LinkPlus V10, LinkPlus V14. When im in the PC link program and tries to connect the ecu does it pop up this: Unable to connect the Link ECU.
