Package includes the following:
-- mechanical fuel injection (MFI) jetting calculator web program (1 year membership; renew for $90/Y)
-- custom training / consulting for a racing professional setup right out of the trailer
-- basic packages also available for $90 and for $250

-- https://mficalc.com/mfi-consult/
-- formerly ProCalc, ProTune Adv
ideal gift for special occasions for the mechanical fuel injection (MFI) tuner
-- ideal for new MFI racers
-- ideal for new MFI combos
-- ideal for major baseline MFI changes
NOT FOR carbs, EFI, Lucas, or OEM fuel inj (rochester, bosch)
MFI tuning for land or water racing
MFI tuning for drag, sprint, top speed, tractor pulling, circle, ...
MFI tuning for 4 or 2 cycle, rotary
consult service data base with thousands of the best MFI setups from different racing
jetting for normally asp or forced induction
forced induction: roots, screw, centrifugal, turbo, compound turbo
determine jetting to adjust for air density altitude
-- calculate jetting to take an optimum dyno, flow bench, or previous racing combo to any air density
-- numerical control to determine jetting changes instead of trial and error
jetting changes for different air density altitude with:
-- engine size changes
-- different fuel pumps, nozzles, bypasses
-- increased fuel pressure maintaining the same GPM / HP ratio to the engine
set up jetting lookup chart on a spread sheet ahead of time:
-- for an entire weekend of air density changes
-- for different racing tracks or altitudes
for forced induction:
-- determine jetting for blower size or OD changes
-- determine OD changes for weather to keep same power (bracket racing trick)
determine jetting to control GPM to engine
determine air to fuel ratio (AFR) from jetting/fuel pump, engine size, air density
determine proper main bypass / high speed bypass combination
determine proper bypass enrichment for ram air with speed
determine bypass BDK or All-valve settings for nitro racing
determine Hilborn valve settings for turbos, centrifugal superchargers
add the ultimate: air to fuel ratio (AFR) to your tuning capability
determine jetting and fuel pump size for different fuels or changes to fuels
-- methanol
-- nitro from 1 to 100%
-- ethanol blends, E85
-- M5
-- racing gas: tuning for changes in different blends
calculator can be calibrated to your data recorder units
calculator works on stationary or portable web devices.
calculator works on more than one device.
