Hondata

I have been trying to start my swapped car. I have k pro v3 in a prb ecu. I registered it with hondata and went on to try to start the vehicle. Long story short the ecu has a flashing red led while connected to the kmanager with no green led. At the bottom of k manager it says ignition off even when key is on. Cannot successfully upload a base map to the ecu. Thanks in advance for the help.

You should try the ECU in a known working vehicle such as an RSX. As it sounds like there could be a wiring fault in the vehicle or the ECU may have been damaged by a wiring fault.

These is a wiring issue I have since found out that there was no 12v power going to the ecu. From the main relay.

Hello.
I bought used pnf kpro 3 and only red led is flashing when connected to laptop.
It also says that ign is off when key is turned on.
I have 2 other prb kpro 4 and car is working fine with those ecus.

Can i swap kpro 3 board from pnf ecu to prb ecu (with kpro 4 at the moment) to test
is problem with kpro board or ecu itself? If v3 board is fried can it damage prb ecu?

Thanks

Yes you can try that.
