Hondata

Hey I think I have a bad s300 board. Car started and ran fine one day and next car had solid cel and led by usb was red. Key off and on couple times led would go green and car would run fine. Let car run and sometimes would run 10min sometimes 10sec led would go red and car cut off. First thought was ecu socket not good. Re soldered ecu to see if that was problem but didn't help. If you push very lightly on corner of board with ign on right by center ecu cover screw hole led will flash from red to green like it has a loose contact. Put s300 in another p28 that already had hondata and same thing. Put good s300 in my ecu and works fine. Acts like board has bad solder joint or bad trace or something? I've had this s300 for a while just never used it. Prob a year or more. Didn't no if anybody has had any similar problems?

What is the serial number on the s300 board inside the ECU?

S300-2201

I am having the exact same problem. I emailed the sales@hondata.com but will send another to support. It's been driving me nuts not being able to drive the car with now cool weather! Thanks.
