LaBella's Auto Repair Map/MAF Sensor Enhancer DEMSE

This device is experimental and worked on OBDII and OBDI systems. Use of this device may void your warranty. It an easily be removed if need be, however. This device is considered experimental and no warranty is implied as to its performance or intended use or misuse. It is not intended to be used as a stand alone device but used in conjunction with supplemental hydrogen (Brown’s) gas generator or an H2O water injection system. When the term computer is used herein, it refers to the vehicle’s ECU (Environmental Control Unit) or ECM. Some vehicles may have more than one computer but the one that controls the fuel system is the one we are speaking about. OBD (On Board Diagnostics) OBD I is pre-1996 and all newer cars have OBD II.
Hydrogen generator installation without the DEMSE (Dual Edge Map Sensor Enhancer) will result in no fuel mileage increase because your car will sense the increased oxygen level produced by the HHO hydrogen into the engine and the computer will calculate that the engine is running too lean—not enough fuel— and it will increase the fuel injected into the engine, sending it into a rich mixture. This could result in even less fuel mileage than previous.
The MAP (Manifold Absolute Pressure) sensor and/or the MAF (Mass Air Flow) sensor are tied into the intake manifold so that they can calculate pressure. In the case of the MAF sensor, it calculates intake air volume passing into the throat of the throttle body, which is also connected to the intake manifold. These sensors simply vary voltage that the computer sees so it knows how much or how little fuel to put into the engine. It uses voltage between 1-12 volts depending on the vehicle. The enhancer DEMSE can be used on either the MAP sensor or MAF sensor. If you have both on your vehicle, use the DEMSE on the MAP sensor only. If you have no MAP sensor but have a MAF sensor, use the DEMSE on the MAF sensor. See illustrations for use below. The arrangement of resistors in the DEMSE enhancer simply takes the already normally low voltage signal and weakens it more to lean out the engine. It can be leaned out enough to kill the engine, starve it for fuel. You can control the factory mixture of fuel/air ratio of 14.7 to 1 (which equates to 14.7 parts of air to one part gasoline) down to 20 to 1 or even down to 50 to 1 or even 100 to 1.
