difficult to drive when cold, particularly with gear changes, try increasing the coolant
correction factor for the throttle pump.
An engine that will idle when warm, but fails to idle cold unless a tiny amount of throttle is
applied may require idle speed control, with a fast-idle function for when the engine is cold.
The E6X can control an Idle Air Control motor that will perform this function.
A.9 Fuel Consumption
Poor fuel consumption is a result of a too rich mixture. If the fuel consumption in traffic is
poor but the highway consumption is good, then it could be the areas of the map used for
accelerating that need to be leaned out. The throttle pump may also waste fuel if its values are
too high. Also try using the fuel cutoff on deceleration feature.
If the city consumption is fair but highway cruising uses too much fuel then lean out the light
load bars on the 2000 rpm to 3000 rpm maps (This is where most cruising takes place).
If the cold start map is supplying too much fuel on warm-up this will also affect the fuel
consumption of the vehicle.
