Nedenstående er uddrag fra denne artikel:
http://origin-videos.trailerboats.co...§ionid=315 at det skulle være MEFI IV ECMs Volvo bruger, men det er en ældre artikel og jeg fandt et andet sted hvor nogle klagede over at Volvo ikke brugte MEFI ECM, så måske bruger Volvo nogle andre ECM i deres nyere modeller ?
PLAYER INTRODUCTIONS
Each manufacturer’s sterndrive package has certain advantages over the other. MerCruiser’s 4.3 MPI with the Alpha drive has a weight advantage, tipping the scale 42 pounds below Volvo Penta’s 4.3 GXi with the SX drive. On the other hand, Volvo Penta says the SX’s added underwater gearcase length increases stability, improves handling and positions the propeller farther aft for a stronger bite, resulting in quicker acceleration.
GM Powertrain indicates that the Vortec 4300 marine engine it supplies is rated at 223 hp, which is 13 to 23 hp more than the automotive versions. Volvo Penta then calibrates its 4.3 GXi to be 225 hp at the prop, while MerCruiser rates its 4.3 MPI at only 220 hp at the prop. We did not check either engine on a dynamometer.
One of the biggest differences between the two offerings is the choice of electronic control module (ECM) technology to operate engine functions. Volvo Penta uses GM’s MEFI IV, a fourth-generation ECM that uses hybrid technology to optimize fuel and spark. MerCruiser, on the other hand, uses the 555 ECM from Motorola, which makes it compatible with Merc’s SmartCraft system.
