I have a 1jz GTE vvti on an emu classic with the adapter harness from ecu master
The car jumps from 9v to 12v constantly I can’t find the source of the problem. The car runs perfectly and I daily it on a stock ecu. It only has an issue when I plug the classic up. [Video](file:///var/mobile/Library/SMS/Attachments/10/00/FE7E4E80-749A-4953-9A5A-576029B916CD/IMG_9900.MOV)
