Occasionally we get a bit of grief about how we choose to power up the modules, injectors and sensors with our standalone harness and fuse block.
Our standalone harness requires turning off the DTC P2510 for the ECM Powertrain Relay in every ECM tune. This is because we do not rely on the ECM to shut down the injectors and sensors. When 12 IGN is cut to our pink/black wire everything shuts down instantly.
At the end of the video the key was turned off and that's what stopped this runaway fueling situation from becoming something very bad.
