Basic Tuning with the Pro Tuner System 137
Generally, the most compensation is required at the lowest speeds & loads. In the tables
this would mean the low percentages of throttle opening. The amount of load
compensation required decreases with an increase in throttle opening. The tables work
together to maintain engine speed when a sudden load is applied. The spark offset table
provides the fastest reaction to a load change, and the IAC offset table will provide the
extra air required for extended load cycling. Start with the values that are in the tables
and make small changes as required to minimize RPM drop.
It is better to have some
speed drop than to be too aggressive in tuning these tables.
WARNING: Do NOT make these table values too large or an RPM increase could
result during a load cycling; which could cause undesired acceleration!
