Timing is Timing all it is used for is to get the spark to happen at the right time so you can build the highest combustion pressure possible when the Piston is near TDC. So if you had the same setup on two different engines and the only difference was compression ratio. The Higher Compression Engine would need less timing for a given fuel because pressure and heat would build to fast and the entire mixture would instantaneously all combust before the piston hit top dead center(detonate) an cause to great of an opposition to crank shaft rotation to be safe for the engine. So on both engines you can only build so much pressure just before TDC to prevent detonation. At and after TDC the Highest Pressure Possible is the goal. So wouldn't the higher compression make higher pressure. Fuel Efficiency would also increase to wouldn't it?
