Basic Fuel Injection Concepts & ModesAir to Fuel Ratios

a Gasoline (100% Gas) A/F 14.70 to 1

b Gasoline (10% ethanol) A/F 14.08 to 1

(most older vehicles programmed at 14.7 to 1 a change is needed)c Gasoline (E85) A/F 9.80 to 1

d Diesel A/F 14.50 to 1

e Injector Cycle / Valve Intake

(gasoline- Injects on back of intake valve for cooling effect)f Close Loop = Cruising / Fuel Economy Mode

(2 bbl carb mode light throttle positions) g Open Loop = Power Mode / Hill Climb

(4 bbl carb mode over half throttle positions)h What is Ideal Air Fuel Ratio?

Corrections with Calibration / Tune1. Close Loop / Open Loop Mode Enabled

a. More HP/TQ when needed over half throttle with only 87 octane fuel

b. Open Loop aids spark knock and cooling intake valves

2. Transmission

a. Quicker converter lock ups for power & economy

b. Optimized shifting to enhance large gear spans

3. Exhaust

a. Headers / Ypipe / Muffler

Basic Ford 2v V10 6.8L ConceptsNegatives1. Close Loop 100% of throttle = no power starves for fuel

2. Timing Retard via no open loop

3. Converter Lock up delays = no power to wheel / heat

4. Large gear span between gear commanded 1,2,3,4

5. 99-00 years NON PI heads (Performance Improved)

a. 97-99 275 HP

b. 00-04 310 HP

6. Exhaust Ypipe restrictions 99-04

a. 2 one inch diameters / 415 cu.

Basic Ford 3v V10 6.8L ConceptsNegatives

1. Open Loop delay 60 seconds at WOT

2. Drive By Wire Torque System =Torque Management

3. Converter Lock up delays = no power to wheel / heat

4. 5 forward gears not completely used, normal / tow haul modes

Corrections with Calibration / Tune1. Close Loop / Open Loop Mode Enhanced

a. Max 2 seconds delays

b. More hp/tq on just 87 octane fuel / 75 tq ft.lb-30 hp

c. Open Loop aids spark knock and cooling intake valves

2. Drive By Wire System

a. HP/TQ command more get more / it has it already

b. More torque at wheel equals power and economy

c. Better throttle response

3. Transmission

a. Quicker converter lock ups for power and economy

b. Optimized shifting for 5 forward gears

4. Exhaust

a. Headers/ Muffler for improved HP/TQ

FUEL ECONOMY TIPS & TRICKS

• Lighter Weight Tires, check before you buy!

•Drive by Rpms under 2000

•Drive by EGTs (diesel) low temps good mileage

•Best Economy speed in a RV 60-62 MPH

Basic GM V8 8.1L ConceptsNegatives

1. Open Loop delays

2. Torque Management Restrictions

3. Converter lock up delays

4. 5th gear at 57 mph

Corrections with Calibration / Tune1. Open Loop delay max 2 seconds

2. Torque map enhanced / Ask for more torque / get more torque

3. Quicker converter lock ups

4. 5th gear engaged by 55 mph
