Q&A


3/19

Standard for Better Emission


4/19

OBD = On Board Diagnostic Reporting System

OBD-I = Level 1 Std => Not really a standard,each manufacturer had different method of

reporting system and different DiagnosticConnectors.

OBD-II = Level 2 Std => Std Diagnostic Port,Full Control for Engine Ops, Chassis, andaccessories.

The Quest for POWER


9/19

Optimizing A/F ratio and ignition timing for part andfull throttle acceleration.

Optimizing A/F ratio for Cruising. Remove Flat Spots (Smoothing Drivability).

Slightly Increase RPM Limiter. Remove Speed Limiter. Optimize Torque Limiter. Adjust Ignition Timing. Adjust Fuel Compensator. Adjust Boost (for Turbo / SC applications). AFM Calibration Throttle Position vs Fuel Enrichment Many many more.

Pre-OBD => Re-chipping.

OBD-I => Re-chipping or Re-flashing thruProprietary Diagnostic Connector (Serial

Programming). OBD-II => Re-chipping or Re-flashing thru

OBD-II port (Serial Programming), orprogramming using BDM Tool (Specific toMotorola MPC5XX based Processors).

OBD-II Standards (and Future Standards).

OBD / II to ECU Protocol Interfacing andProgramming.

ECU Technology => More Stringent Controlover Emission, thus tighter engine operationtolerance.

ECU Maps scrambling. Checksum algorithm.


15/19

More efficient engine operation, thus more fuelefficient => For normal driving behavior, fuelconsumption is LESS.

More power => Engine is tuned to within itsmechanical potential => More power isavailable when needed.

In plain term: YOUR CAR IS MORE FUN TODRIVE!!! .. And MORE DRIVABLE.


16/19

7% - 15% Horsepower Increase for normally aspirated(N/A) engine (Depending on how optimized the stockengine is).

10% - 15% Torque Increase for N/A engine.

10% - 50% Horsepower Increase for Forced Induction(FI) engines, depending on boost level, gasoline orDiesel engines.

30% - 75% Torque increase for FI engines, gasoline orDiesel engines.

Much better part throttle operations, remove flat spots. More torque below peak torque => better drivability. Much better passing power from peak torque to

redline.


17/19

Most Cars whose ECUs have separate DataChips.

Usually Bosch and Siemens based and

licensees. Additionally: Delphi, Sagem, Marelli, VDO,

etc.


18/19

Why did manufacturers NOT optimize theECU in the first Place?

Will my car consume more fuel?

Will it void my car warranty? Will it shorten the life of my engine?

Will it have long term negative effect on my

car?
