M52b25tub engine swap

[Leehe30]

Ongoing project, a few years ago I acquired a cheap m52b25 tub engine and gearbox and had a touring shell sat around so I put 2 and 2 together, it’s all in the car with the sump swap. Some time has passed with a house renovation.
Wasn’t thinking ahead about wiring and and ecu.
can I purchase a ms42 ecu with ews delete and purchase and an m52tub to e30 adapter loom. Will this solve this problem or is it much more complicated than that
I’m sure this has been asked before and sorry for that.

If you already have the M52tu harness on the engine and the engine is installed, then all you will be needing is the harness adapter and the EWS deleted ecu.
If you already have an MS42 ecu, we can also eliminate the EWS.
