Hyundai I30N Fastback - Disconnected Bi-Modal Valve Experiment

[@astonforster4435]

How would one do this? Is it a plug in the engine bay? If so, whereabouts?!

[@CrackingGate]

On the right handside exhaust tip you will see a plug connecting to a little electric motor (that controls the flap), it is that plug.

@@CrackingGate What about water damage to the connector, now that it's no longer plugged tight?

[@CrackingGate]

@@Cernunn0s90 you could protect it with a plastic wrap and tape it up.

Have you fitted a Res delete yet? I’m looking at getting the RPM Anti Drone Res delete for my i30N and just wondered what the sound difference would be?

[@CrackingGate]

No res-delete yet Ric. Still tossing up whether to go a mid-pipe or not, the obvious difference is cost between the two but I would like it to be reversible with no modification of the standard system, so I am leaning towards a mid-pipe at this stage. Sounds great either way you go though.

Another way to do this would be to just remove the fuse for the bi-modals. Was a quick backyard mod for the VF SS when they started coming out with bi-modals. If it’s anything like that you had to first put the car into sport/track mod or open exhaust in the System settings on the head unit, then pull the fuse. Either way. Results should be the same. 🤙🏼

[@CrackingGate]

Will have a look into that method. Would be a lot easier to do. 👍

[@nikic7654]

wich fuse is it?

[@vitorharalambus6537]

So, when you unplug does the flap already have to be open? Does it throw any error codes?

[@CrackingGate]

This was more so an experiment rather than a long term solution. When the plug is not connected the valve motor isn't energised so it will stay open. I didn't experienced any codes either as I believe it doesn't affect emission control as it is at the end of the system. Another viewer claimed it saw a significant rise in fuel consumption, however, I have not verified this. Again with making changes to a vehicle it is at your own individual risk.

[@alexandrospapadakis7511]

the consumption will climb to god..i doing that when i have already 17 liters and after unplugged i was 28.. also be careful with the gear changes because the movement of the car will become sluggish and delay behave after you release the clutch after gear change..
