Hello, I am new to the Volvo community and I have just bought a 84 240. My plan is to get a hold of a b230fk. I have just purschased a LH 2.4 wire harness and i also got a few ignition ecus with the buy, now for my question. I have looked at different discussions around this topic but i still feel like i didnt get an answer. Two of the four ignition ECUs i have, does have this "daughter" board that i have heard people talk about that you need when chipping. The 1st ecu name : Bosch 0 227 400 146. Second one: Bosch 0 227 400 149. These two does have the daughterboard in them, can i buy any "turbo" chip and stick them in there and call it a day or does not these ECUs work with the LH 2.4 or b230fk? Thanks. I will post up some pictures.
