You would have to build an entire new map. Someone that knew what they were doing could take your WOT #'s, your idle numbers ( lbs. of fuel) and build a basic map, or if they already had one built for other customers cars very similar, use theirs and slightly modify it to fit your engine. Either way some tuning will be mandatory to get you going. But there is no plug and play between the two. The Alfa uses 0-100 % throttle to make its changes, the SD uses your MAP ( Manifold Air Pressure) to do the same thing.
I agree, if what you have runs good on Alfa, leave it alone. |
