Whether you have a stock engine, crate or custom-built engine, HP Multi-Port systems can help you maximize performance! By utilizing a laptop or the optional 5. HP Multi-Port systems include: intake manifold, billet throttle body, ECU, wiring harness, fuel rails, and related small parts.
Fuel pump and injectors are available separately to fit your requirements. About Holley EFI. From there, some programmers allow further alteration of the fuel and ignition curves. What they lack in ultimate sophistication, handheld programmers make up for in user-friendliness, as they don't require learning how to interpret and navigate dozens of different programming screens. Additionally, they can adjust rev limiters, shift points, speed limiters, and cooling-fan activation points, plus display live data from sensors and scan and erase trouble codes.
Most also allow you to compensate for a change in tire diameter or rear gear ratio. Although they may not suffice for heavily modified combos, they'll work just fine for most stock or mildly modified street machines. Just as with a full-on standalone system, the software displays live fuel, spark, rpm, coolant temperature, manifold vacuum, O2 sensor, and throttle-position readings. In addition to data-logging capabilities, the software allows control over cooling fans, transmission shift points, and speedometer calibration and has provisions for additional ancillary inputs such as wideband O2 sensors.
Truly astonishing for a setup that reflashes the stock computer, files are uploaded in mere seconds and optional two- and three-bar MAP sensors for forced-induction applications means big boost can be had without aftermarket EFI.
Visit www. PMS The 5. Adjustments are made on the unit itself, so no laptop computer is needed. In addition to increasing the computer's memory capacity, the PMS allows full alteration of fuel and spark maps, bumping the rev limiter up to 9, rpm, separate nitrous and boost adjustment tables, real-time engine monitoring, two-step rev limiters, three-bar MAP sensors, and cooling-fan control.
An optional low-impedance driver lets you run big injectors, and the PMS can also interface with a laptop computer for data logging. AFM helps you get started by providing a baseline program already loaded into your PMS based on the engine specs you give them.
Painless Performance has you covered with its new Perfect engine management system. And it really is painless. The fully plug-and-play system comes with a weather-resistant computer preprogrammed for near-stock applications that Painless says boosts horsepower and gas mileage, and a wiring harness that mates to OE sensors.
The company will soon offer software allowing further fine tuning. Ford 5. Other features include a data logger, speedometer recalibration, and cooling-fan, rev-limiter, and shift-point control. The software also works as scanner by displaying trouble codes and allowing users to erase them. Log on to www. TWeecEROne of the biggest pains of tuning stock computers is waiting minutes for your reprogrammed files to upload.
The TwEECer lets you program up to four different calibrations and switch between them while the engine is running. For example, you can change from a fuel economy to a performance or nitrous tune on the fly. A fifth mode allows switching back to a stock program. The CalEdit software features an easy-to-interpret graphical display, and an optional data logger can record up to 10 samples per second of information.
Time to hire a proIf you've never tuned EFI before, it's easy to get lost, especially with a standalone system. There are a bunch of tables and options and it can be intimidating. Even if you get the car running, you're probably leaving power on the table. Here's where to go to find a pro to either bail you out and get the car running, or to tune it for maximum power.
How it WorksThe alphabet soup of sensors common in all EFI systems may be intimidating, but it's the input from these same sensors that facilitates the added precision of fuel injection over a carburetor. Most aftermarket and factory PCMs are speed-density systems that calculate engine load based on rpm and manifold-pressure readings from a manifold absolute pressure MAP sensor.
The PCM uses that engine load reading, usually measured in kilopascals kPa , and matches it up with the corresponding fuel and ignition maps for the rpm the engine is spinning at that instant to provide the proper amount of fuel and timing advance. So an engine can idle when the throttle blades are closed, an idle air control IAC valve mounted on the throttle-body provides a controlled vacuum leak to maintain desired idle speed.
Contains system-specific data. It is comprised of one or more boot entries for each operating system or bootable program installed on the computer. A boot entry is a set of options that defines a load configuration for an operating system or bootable program. Specifies the boot parameters for the entry. Boot parameters are commands to enable, disable, and configure features of the operating system. The EFI Boot Manager passes these parameters to the bootable device or system to be interpreted and implemented.
For a list of the boot parameters that are related to driver debugging and testing, see Boot Options in a Boot. Specifies the location of the EFI boot loader for the operating system. On EFI-based systems, each operating system or bootable device has its own copy of the boot loader on the EFI partition.
This identifier is assigned when the boot entry is created, and it does not change. It represents the boot entry in several lists, including the BootOrder array, and it is the name of the directory on disk in which the system stores data related to the boot entry, including backup copies of the boot entry. An EFI boot entry ID has the format, Boot xxxx , where xxxx is a hexadecimal number that reflects the order in which the boot entries are created.
