Hi all, new to the forum. I have a R33 GTST Skyline with an RB25DET engine. The vehicle is fitted with a V500 Wolf ECU with a WOLF R32/R33 GTST adaptor harnes and a adaptor module?. I downloaded the latest of the v500 software from the Wolf site lastnight. My laptop uses Windows 7 32 bit software. The Wolf software wouldnt load onto my laptop until i installed NET.FRAMEWORK 1.1xxxx. I have the software installed, i am using an ATEN Serial to USB adaptor on my laptop as it doesnt have a serial port. I have set the usb port on my laptop to comm 1. When i connect the ECU to my laptop with the Aten adaptor and turn the ignition on i get an error. The error repeats itself over and over, referring to the loss of power during connection. I have narrowed the issue down to the USB adaptor as a friend connected to this ecu today with his Windows 7 laptop, but using a serial port. He also tried with an Aten adaptor and got the same error as me. Does anybody know of a Serial to USB adaptor that will work for me or a driver download or something i can use to rectify my problem. Thanks in advance.
