Hondata

The ECU's have the same pinout. If it is ever wired incorrectly it will burn out the main relay output and will not operate the fuel pump properly.

You can be tuned on E85 without a Flex fuel sensor.

How to you have the flex fuel sensor wired?

You never mentioned you were using an ethanol content sensor.

If the wiring is correct and the ECU will not turn on the fuel pump then the ECU cannot be repaired. It would have to be replaced.

It sounds like the ECU is damaged and would have to be replaced if you want it to work as it should.

Have you contacted K-Tuned about the issues you are having?

You need to try this ECU on a known working vehicle first to make sure it has not been damaged and is working correctly. If it is then you will need to correct the wiring faults in your vehicle that are causing the issue.

Yes that's for a stock car.

You should not plug in the USB until you have the issue resolved or you could damage the K-Pro and the ECU.

It sounds like there has been a change to the head unit. We have a 19 Civic SI that we will look into this in the next week or so.

The one labeled Hondata reflash would probably bee a good one to start from.

We do not know yet if the 2019 will even work as this has not yet been tested. Since this has an updated head unit it may be something that Honda has changed.

Have you paired the FlashPro via the Android Bluetooth settings before trying to connect in the App?

You need to try the ECU in a known working car. If the fuel pump still does not prime and turn on properly then the EUC is damaged and will have to be replaced. If the throttle body has been modified and it has over rotated the TPS sensor it may have damaged it internally.

Please post a datalog of it connected even if you don't see anything.

correct.
