0x1 3.1.0-injector-pressure 5C2ACYB 2005 E-350 5.4L E85 Code-Traced v3.1.0 Final code-traced E85 calibration definition for strategy 5C2ACYB. Primary E85 fuel control is the paired big-endian IEEE-754 stoichiometric AFR constants at 0xF4970 and 0xF4974; edit both to the same value. Startup fuel surfaces are exposed because their lookup paths are code-referenced, but their exact mode identities remain unresolved. Base spark and active correction paths are exposed; stock-zero alternate paths remain explicitly marked DO NOT POPULATE. No speculative injector, transient, torque, rev-limit, or power-enrichment definitions are included. Added the contiguous injector characterization block at 0xE31A8-0xE32C4: injector voltage offset and four differential-pressure compensation functions. Because the code export does not preserve Ford scalar names, pressure functions are labeled A-D rather than falsely assigning low-slope, high-slope, breakpoint, or offset identity. There is no fabricated single fuel-pressure scalar; this strategy stores pressure breakpoints and multipliers as functions. Microsoft Copilot with Eric Floth Confirmed direct fuel stoichiometry constant, big-endian 32-bit float. Stock value is 14.640 AFR. For a fixed-fuel E85 calibration, enter the measured/selected stoichiometric AFR and keep A and B identical. Do not use this field as a commanded wide-open-throttle AFR target. Verify fuel pressure, injector duty cycle, lambda, trims, and cold-start behavior after changing fuel. AFR 3 0 0 $$ Confirmed direct fuel stoichiometry constant, big-endian 32-bit float.
