I just "finished" my m30 swap. Its an m30b35. I used the m20 harness. It has the ecu from the donor car which was an automatic. My e30 is a manual so idk if the ecu would be causing the problem because of the manual transmission. But watch the video please and tell me what you might think is wrong. The car runs fine at idle but when i rev it, it does what happens in the viodeo. Thanks
