I have a link g4plus in my 1997 toyota chaser 1jzgte vvti. The car was tuned with it and was really fun to drive for a month. One say i went for a drive and i shut the car off and it wouldnt start again. The ecu was damaged. The car was then towed to the shop where i had it tuned at and they sent the ecu out to get repaired. Ive attached what they found with the ecu. After getting the ecu back it was then installed in the car and it ran like crap 20 plus afrs. The shop was replacing fuel pressure regulators and stuff of that nature and couldn’t fix it. I then had the car towed home cause they had no idea where to go with it. I then found out that pulling the efi relay made the car run way better but doing that made the fuel pump run at 10 volts but around 14 to 15 afrs at idle. The efi relay has power on both sides 14 on one side and 10 on the otherside. Seems like something is backfeeding on that circuit. Also when the car was at home I installed the maf and factory ecu and the heatsink was getting super hot while the car was running and now it doesnt start with factory ecu now. I currently have the link ecu installed in the car without efi relay. Im looking to see what to do next any help is appreciated. Ive also replaced the ignition switch cause the car doesnt turn off when relay is connected up but made no difference
