This system is built and designed for simplicity and ease of use with maximum control over a very complicated engine system. To cure the issue, we decided to use an electric fuel pump and plumbing from and , along with a tank and pickup from. Coil-per-cylinder ignition systems are engineered to have one less link in the system. . West Bend Dyno can't even get it to fuel correctly with the correct parameters. I took almost 7 months to go to print.
Simply hook it up, answer the basic setup Wizard questions on the included hand-held display and watch the system tune itself as you drive. No problems and engine runs good. In the followup dyno test, the engine made more slightly more power and torque through the 6,000 to 7,000 rpm peak power range. We mounted our Holley Dominator fuel pump inline and just below the chassis on the frame rail. Some options The returnless option is viable due to the built-in fuel-pulse damper for precise fuel control. You can optimize one setting for everyday driving, others for racing conditions and still another for improved fuel economy.
This helps resolve or eliminate the possibility of any misfire or rough idle issues. As you can see by the O2 sensor in the photo, this system uses stock style sensors and injectors. With a single 1050 cfm carb modified only with jetting and air bleeds, the car runs in the low 9. My tuning experience before this install involved using a vacuum gauge and a timing light so this was my first fuel injected HotRod. I set my timing to not advance till 1,200 so it's stable at idle speeds of 850. Everything is handled with the onboard system.
Wiring harnesses are modern mesh wrapped with clearly labeled connectors. Because the system is continuously tuning, any engine upgrades that are made in the future are simplified as well. The automakers did get away from return lines to cut expenses, but either way is okay. This combination is said to offer gains of over 26-horsepower. You can plug it in and drive without knowing anything about it. There are no special trips to the garage for tuning changes.
The preference for this project was under the dash, close to the passenger-side kick panel. Note the position of the fuel-pressure sensor, which is mounted on the return line. We covered that engine build in a two-part series of articles, and. After initial setup, the hand-held can be used as a digital dash with the included suction cup window mount. Their support sucks, Sold it on ebay and went to a carb for a couple of years until my blood pressure went back down. Among those are: self-tuning strategies that eliminate the need for a laptop and advanced computer skills; fast startup procedures and continuous self-learning capability; minimal hardware and electrical connections; and a self-contained throttle body with all the necessary injectors and sensors to facilitate an easy installation.
A laptop or tuning experience is still not required as the system simply tunes itself as you drive. They also have a forum online that has been very helpful in answering my questions. Both fuel lines were routed under the floorpan to the engine bay. Once it's warm it seems to have an inconsistent idle surge. No charts or questions to qualify for returnless like other competitors. Overview On Self Tuning The self-tuning nature of this system is the biggest selling point.
More important to racers, the new system will work with engines capable of 1,200 horsepower. After initial setup, the handheld can be used as a digital dash with the included suction cup window mount. I've gotten zero support except for try this or that. Positive and negative power lines must be connected directly to the battery. We need to make some major changes in the fuel system, or we face a fuel supply problem that would be on the scale of trying to suck a basketball through a straw. The fuel inlet line runs from the regulator to the forward port on the throttle body.
Surging would be typical of to much proportional and not enough integral and derivative. This Throttle Body delivers a total package approach for any 4150 Holley square bore type intake manifold. Run one calibration on the way to the track, and then with the push of a button, have a more aggressive setup ready for the race. When the conditions change, such as an ambient temperature increase during the day, then the carburetor needs to be adjusted accordingly. Simply select the tune-up you need with the flip of an in-car switch. Other features include integrated nitrous bungs, and perfect bolt-on fitment that allows the use of factory accessories without modification or clearance concerns. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber.
Idle with it is somewhere between 750-800 when steady and even in gear with my 2700 converter. The test engine is based on a 400 block with a 4. In addition, they upgraded the user interface for power adders, including advanced forced induction, progressive controllability and other advanced racing specific strategies and features. Electronic fuel pressure measurement is standard on all kits, and each one works with a wet nitrous system. It advertises that it can handle timing but I am skeptical. The kit supplies an installation bung that must be welded to the exhaust systems — either on a header collector or standard exhaust system downpipe. The return line on this project took advantage of a dedicated fitting on the fuel cell see below.
If a returnless system is preferred, the forward port would be plugged and the fuel inlet would be mounted in the rear port. The baseline tuneup will generally be on the safe side to avoid hurting the engine. The sensors used in the feedback loop have gotten so dependable and have improved to the point where this automatic performance is possible, even with frequent engine upgrades. The hand-held display can be set up as a dashboard for engine performance with several different display options, allowing the user to pick what features, or all of the engine parameters, to monitor on the display. We should round up enough pissed of users and file a class action suit against them.
