You ( Hodata ) recommended to relocate ECU ground to valve cover. Why dont just add a wire from battery GND to ECU GND ? This would be way more better then just relocating itself. Im planning to add more ground wires to alternator, ECU , chassis . Will see if it helps with WEN on cold car .

Do not go adding additional gronds from the battery to the ECU as this will just create ground loops and more problems. Follow the insturctions we have given.

Tried to relocate ecu gnd , tried to add additional grounds .. Nothing changed at all. Same old story . 3-5 mins of idle or drive on cold car and flash successful. Anyway , i love flashpro ! My car was a vegetable and now its a blast !
