Ignition Cut Randomly

Post by Looneybinjim »

Run into an issue where I'll be 1/4 or WOT and it just cuts for no reason. I've looked at my data logs and it seems to be the speed sensor dropping out causing the cut, however I changed the the speedo sensor with another known good one and still have the same issues. I've also tried turning off launch control, vtec, and boost control but it still does it no matter what. I just bought a new jumper harness but haven't installed it yet. Here are my data logs and "tune" so far.

If the speed sensor is cutting out, you need to determine why that is happening. I would recommend you try your ECU in a known working vehicle and see if the problem is present. If it is not, then you need to resolve the issue in your vehicle.
