...a bugger this one

..Got a level 8 ECU with a std board in a P8 case and i have plugged Stu's chip in which appears to be a small board with a chip plugged in so i plugged it into the board and its too high..so the top wont go on...am i meant to take out the small board and plug direct to ECU floor?

Would phone Stu but i am only just doin it and he will be shut.
