All Buick PCM,Buick ECM & Buick ECU engine computers from Flagship One, Inc. are precisely programmed and flashed to meet your vehicle's specific requirements. Our Buick PCM, Buick ECM and Buick ECU module units that are labeled plug & play will not require additional programming. Common issues that occur in Buick’s as a result of a failing ECU include stalling, low fuel economy, misfires, and a permanent check engine light. Oftentimes simply reprogramming your original unit does not suffice in resolving this issue and a replacement unit is required. Replacing your unit can be a painstaking and expensive process, however, cutting out the need for a dealership enables us to sell our units at a reduced price for the same quality of service. If you can't find the exact part that you are looking for, simply give us a call because our supply of vehicle controllers is the nation's largest so you'll be sure to get just what you need -- at a price you'll like!
