Control Unit

[Superm^n]

Does anyone where i could get the Control Unit of my galant. its the V6 manual 2.0L engine. I think the engine is 6A12. Theres a couple here in the Http://vstore.nopi.com ('http://Http://vstore.nopi.com') otherwise known as the TGC Nopi Store. My mechanic sais the part number is MD 189548 but i cant see it anywhere here. only 926+2837, 926+2838, and 926+2839. Is this otherwise known as the EEC? They said to get it fixed rather than getting a new one. If I knew how much a new one would cost, Then ill decide if ill get a new one or to have it fixed. what do you reckon guys?

Thanks for our help
