ECU Connection Failure

I'm trying to run a Honda K24 with this EMS and am having connection issues when I'm cranking the car. The EMS connects fine to my laptop, I can upload a calibration, but when I start to crank the car the EMS will loose connectivity. It seems that the EMS is staying on by still outputting 5V and is getting 11.5V while cranking but is dropping communication. What could be the issue?

Sounds like a possible EMI

Sounds like a possible EMI problem, Does your usb cable have ferrite beads at both ends?

Where is the ecu mounted?
