CANFlex Issues

[Notorious9i6]

"I am also running issues where my DE5 exhaust valve is acting weird. Sometimes it works, sometimes it unresponsive where it just stays doesn’t open or close and is “stuck”. All of this starting happening after installing Hondata canflex."

It was a loose milltek extension connector. Just happened a day after the new mod.

Also contacted support about the cel when flashpro is unplugged! Thank you Hondata

Hi again.
I am still having this issue and have reached out via email numerous times. Called today and for some reason my emails are entered being received on your end. Let me know how to proceed.

No emails have been received and our technician said he emailed you and you got it but did not receive a reply from you. Use a different email address to email us as the one you are using is being blocked on your end for some reason.

I sent PM. I tried 2 different emails and neither were received on your end.

[DE5_Now]

I guess you have PMs disabled...can this be remedied with a phone call?

[Spunkster]

You can call from 9am to 4pm Mon-Fri.

Same issues here too. FL5. Plug in FlashPro and check engine light comes on. Unplug FlashPro and check engine light goes away instantly. I’ve Disconnected battery, reconnect battery, plug in FlashPro, check engine light on with code P0560. Unplug FlashPro and check engine light is gone. Hondata wants me to strip out the entire thing and send in for inspection. Tuner said CAN module or OBD2 harness potential issue. Hondata states it can’t be those as it only shows when FlashPro plugged in. Not that it matters but using OG FlashPro and not USB-C FlashPro.

This happened to my FL5, only when flash pro is connected. Upon further inspection I noticed that the OBD2 connector/extension has pins that aren't fully secured, there is a bit of play leading to an unstable connection, which causes the check engine light.

What's the fix for this issue?
