Radio Interference from S300

Post by kraquepype » Mon Mar 25, 2019 1:08 pm

Hello,

Ever since I installed my ECU w/S300v3, I get radio interfererence while the ECU is on. Is this normal, and has anyone else experienced it?

It is worse with the USB cable plugged in, but still noticeable with it unplugged.

1989 Civic Si, D16A6 with Hondata S300v3

Check all grounds in the engine bay and the ground under the seat.

Thanks, I checked the engine grounds. I was missing the chassis to trans ground and valve cover, I ran those and the car is running better but still get static.

Under which seat?
