| Secret world of chip-tuning... |
|
When the existing power-chip can no longer give you more fuel because of the limitation of the fuel-injector (100% open!), why should you spend a fortune installing a new set of high-flow fuel injectors (some engines require up to eight!) and a new power-chip to drive them? That new eprom can cost you as much as another 300 dollars: older chips can no longer work with the new high-power injectors. Every engine is different, even among vehicles that come out of the factory at the same time: how can an eprom chip cater for the enormous variation of tuning configurations -- for cam change, intercooler change, or differing turbo/supercharger characteristics? OK, you'd listen to the experts, of course they know everything about the manufacturer's ECU and the latest batch numbers that match your car, and every little difference between software version 3.12 and 3.16! Press a few buttons on their lap-top ... a few minutes later, hey-presto! ... a new power-chip is yours for a mere 250 dollars!
Do you know how many engineer-hours a car manufacturer spends perfecting a single chip? You guessed, a lot! Making a change as drastic as different injectors, you are throwing away all the thousands of programming lines ... simple things like stable idling-speed, transient throttle-response, injection-rate and ignition-timing variations on air temperature against coolant temperature on trailing throttle ... that they have spent years developing. Unless these factors are set just right, your beloved car will not be very nice to drive. Assuming your car's manufacturer would willingly hand over its source code, do you think any independent chip tuner would spend 18 months of his time (including testing your car in Arctic and desert conditions!) so as to programme a little chip to run perfectly with your new high-flow injectors? And even supposing he were willing and able to do all that, are you prepared to wait that long? But with the MF2 system, your tuning will be under your own control!  |
| MF2 (Map Fueler - new version 2 ) about 320 dollars or less! |
We at ERL believe everybody should know exactly what they are getting before passing over their hard-earned dollars; not merely a little piece of plastic concealing every bit of machine-code tailored to your car's ECU, unleashing all that hidden potential to achieve ultimate power. The MF2 is based on an open-architecture design, which means that the unit is freely re-programmable at any time, open to any one who possesses a small screwdriver: no computer interface is necessary! If this interests you, read on ... working alongside the original ECU, the MF2 controls its own set of injectors, four high-impedance injectors and two low-impedance injectors (not supplied). It is able to use the signal from the existing sensors, or it can operate independently. 3D-mapping is simple if a load- or pressure- signal is fed into the unit. We are not re-inventing the chip, but merely giving back the control to its rightful owner! More technical information will become available on this web page soon.

| ADJUSTABLE PRESSURE SWITCH |
|
This switch determines the point where the system starts to inject. It is normally fitted to the vacuum side of the inlet manifold (2D mode) for applications where load signal (throttle angle sensor) or manifold absolute pressure sensor (MAP sensor) is available, the pressure can be used in conjuction and enhance the 3-D mapping. The switch is of a 'normally-opened' type, adjustable pressure range 3-30psi (preset at 10psi from factory), 1/4T yields 3psi change. |
| HOOD |
|
This Nitride rubber cap is for protecting the electrical contacts on both injector socket and pressure switch from the harsh environment of the engine bay |
| Standard BOSCH type fuel injector socket |
|
The injector plug comes complete with mating pins and splash proof seal, which enables direct conection to a BOSCH type fuel injector. |
| 10A fuse holder |
|
A standard automotive inline fuse assembly, fitted with a 10A blade type fuselink. |
| Fuel injection loom (Red) |
|
A high quality splash-proof plug, with seals, hosts nine UL and CSA approved wires for connection to the intended equipment/sensors. All mating pins of the socket/plug are gold-plated, all capable of carrying 5 amps of electrical current. An additional pair of wires supplies a stablised output voltage of 5 volts for driving a MAP (manifold absolute pressure) sensor. |
| HARDWARE |
|
All mating inserts or connectors are tin-plated. Other fasteners are made with high quality 316(A4) stainless steel. |
| Mounting brackets |
|
These mounting-brackets are made with 16SWG aluminium, power-coated to resist the toughest conditions; incidentally, the diecast case of MF2 is also coated with the same epoxy-based coating. |
| Instruction manual |
|
A 20-page comprehensively-written instruction manual discusses every aspect of the MF2 in great detail, including over 20 schematic diagrams and illustrations.
