To be more precise and at the risk of sounding redundant, this is basically what I want; only the settings for "diff_normal.cfg" and "diff_hard.cfg". This is my "diff_easy.cfg" copied and pasted:
-- AI Detection speed
ai_SOMSpeedRelaxed = 1.2
ai_SOMSpeedCombat = 0.3
-- Alive time
ai_RODAliveTime = 5.0
ai_RODMoveInc = 1.3
ai_RODStanceInc = 1.0

ai_RODAmbientFireInc = 2.0
ai_RODKillZoneInc = -2.0
-- AI fire reaction time
ai_RODReactionTime = 0.2
ai_RODReactionDistInc = 0.1
ai_RODReactionLeanInc = 0.2
ai_RODReactionDirInc = 1.0
-- Cover fire time modifier (cover fire time specified in weapon)
ai_RODCoverFireTimeMod = 1.0
-- ROD ranges - percents of attackRange AI property
ai_RODKillRangeMod = 0.2
ai_RODCombatRangeMod = 0.6
-- Ambient fire, enemies not in the quota cannot hit the player.
ai_AmbientFireUpdateInterval = 0.5
ai_AmbientFireQuota = 2
-- Low health effect duration and health threshold
ai_RODLowHealthMercyTime = 2.5
g_playerLowHealthThreshold = 40
-- AI voice readability
ai_UseAlternativeReadability = 1
-- Player Health/Energy/Suit
g_suitCloakEnergyDrainAdjuster = 1
g_suitRecoilEnergyCost = 7
g_suitSpeedEnergyConsumption = 110
g_suitSpeedMult = 1.85
g_suitArmorHealthValue = http://www.mycrysis.com/forums/100.0

Thanks again and best wishes.
