Hey guys can this DISA valve be totally deleted out of a m54?

I'm sure it could be but why would you want to? you lose out on all the low end torque benefits. -
It would work. You could remove the DISA assembly and replace with a blockoff plate.
The result would be that you are permanently using the runners that correspond with higher-rpm operations and would lose the resonance at low rpms that boost torque.
Your MS43 may also throw a code if it does't sense the actuator.Attached FilesComment

Ok then , what would you delete for the ecu??
Look'n at a m54b30 swap. My e30 has a m50 into ATM and look'n at the m54 with it's extra torque .E30/ 318i m10, e30 m50 & E34/ 520i m50Comment

a lot of that torque comes from Disa
there would just be a couple error codes from the missing actuator. you really don't even need to delete them, they shouldn't cause a limp mode or anything.Comment

Ok, the problem we have in Australia is m54s are not cheap, and not too many people have done the swap. And I think US M54 and Australian m54's may have differences.
So for the ecu would I delete the EWS, and what else??E30/ 318i m10, e30 m50 & E34/ 520i m50Comment

secondary O2 sensors, SAP if they come with that down there. You'd have error codes related to CAN/DSC that you'd want to delete.Comment

We're shipping a few Ecus to Melbourne iirc for a m54 swap...
Oh and you want to keep disa,
I'll post up a dyno graph in a little before/after
