If it only is flashing the MIL with the key on but not running and there are no error codes when datalogging it sounds like there is no actual problem, and a sensor may not be powered up when just having the key on without it running.

How exactly do you have this wired?

Is J12 cut on the ECU?

Have you replaced the capacitors on the ECU?

yes

try www.car-part.com

it is version 4.

you have not posted a datalog showing the issue.

Are you trying to run closed loop from the wideband?

I believe the soldering of the pins are the most likely cause of the problems. We recommend all capacitors be replaced. You can purchase them at: https://hondata.com/accessories/capacit ... uage=en-gb

The ECUs are all different and do things differently.

It looks like there are a number of bad solder joints for the 14 pin rows for the s300, as the pins are not visible and the through hole vias may be damaged. You may need to use a different ECU.

What do you mean by a board?

The ECU cannot make the ignition go negative.
