17. Why Would Want to Adjust the Spark Timing If your performance tests indicated undesirable symptoms such as excessive engine knocking sluggish acceleration or the miles per gallon mpg indicated excessive fuel consumption you should adjust the spark timing with the Screamin Eagle EFI Tuner Basic Tuning Mode Main Spark Table If the bike exhibited no undesirable symptoms but you want to see if you can improve the acceleration performance you can adjust spark timing with the Screamin Eagle EFI Tuner Basic Tuning Mode Main Spark Table How Would I Adjust Spark Timing You should already have read the closed course track testing instructions and performed both the steady throttle and full throttle tests and determined what if any symptoms you felt you wanted to correct And you should have determined what area of the engine rpm and MAP these symptoms were present in Example 1 Steady Throttle opening of 696 at 2000 4000 rpm under light load indicates no undesirable symptoms but fuel consumption is high This situation is probably telling us that we need to increase spark timing so that the engine is more efficient We know that at steady throttle openings of about 6 that the MAP is between 10 50 kPa because we consulted the Throttle Position vs MAP Table 1 The suggested tuning for this retarded spark timing condition is to use the Basic Tuning Mode Main Spark Table to increase the spark timing in the 2000 to 4000 rpm range from

Advanced Tuning Mode is a multiplier which in part tells the ECM how much additional fuel to add during a throttle roll on at a specific engine temperature This is one of several tables and variables that make up the total Acceleration Enrichment fuel that is delivered to the engine Other variables that affect the amount of fuel added include engine speed map load how fast the throttle is moved and how much the throttle is moved Prior to an acceleration event the engine is running in a steady state condition and is delivering a steady flow of fuel When the throttle is opened further the engine eventually reaches a new steady state condition with a different rate of fuel flow The engine needs more fuel delivered during this transient condition as the amount of fuel in the intake system is less than the engine needs for the new condition On a carbureted bike this is the accelerator pump On an EFI bike this is called Acceleration Enrichment Any changes made to the Accel Enrichment table increase or decrease the amount of fuel delivered while the Acceleration Enrichment mode is in effect Use this Tuning Table to increase or decrease the fuel added during an acceleration event so that it runs properly If engine hesitates coughs or dies on throttle roll on increment the Accel Enrichment cells to increase the amount of fuel enrichment gt If engine sputters or blows excessive black smoke on throttle roll on decrement the

FR Air Fuel Ratio and Spark Advance tables One of Look up table the ECM always uses is for which is a percentage rating of how much air is flowing through the engine while running as compared to its theoretical Capacity For example an engine with a displacement of 88 cubic inches running at 5600 rom at full throttle has a theoretical airflow capacity of 100 when it flows about 143 cubic feet of air per minute cfm If the same engine flows 107 at 5600 rpm it would have a VE of about 75 And if the engine flows about 157cfm at 5600 rpm it would have VE of about 110 That s right the VE can exceed 100 especially in high performance engines that have improved airflow through the engine VE reacts to engine speed and to anything that increases or decreases airflow through the engine The VE Look up tables in the 5 Eagle calibrations are calculated from data they gather while testing live engines on engine and chassis dynamometers and with data acquisition equipment in conjunction with track testing Overview of How the Harley Davidson ESPFI Functions The front and rear cylinder VE Look up tables which are programmed into the ECM tell the ECM how much air volume is flowing into the engine at different engine rpm and throttle positions The ECM also monitors the intake air temperature and manifold absolute pressure which provide it with an indication of air density or the amount of o
