Guys I have a 560 sel engine, gearbox, loom and ecu's from a car I scraped long ago. My original intension was to swap this into a w124, but I seem to be sticking with improving the inline 6 so it needs to go. My question is, how do I tell if I have the standard 5.6 with 250ish bhp, or the 'ece' version with 299bhp? Some of the wiring harness has 'ece' on it, as dose at least one ecu. Dose this mean I have 299bhp?
