Advanced Tuning Although most aftermarket controllers are excellent in terms of engine management, most do not have transmission control for late-model electronic transmissions. It needs to be tilted downward at least ten degrees from horizontal to prevent condensation from damaging the sensitive electronics. There are multiple control strategies that allow control of the wastegate dome pressure or control of the actual manifold boost pressure. The customer can decide how much programming, if any, they want to do! Some products include two passes to tune two separate vehicles. The biggest advantage of the handheld tuners is their ease of use.
The reluctor wheel is mounted to the crankshaft inside the block to the rear. There is also an optional 2-Step Rev Limiter that can be installed and used on the starting line if you plan to drag race your machine. The crank position sensor is mounted to the rear of the block, behind the starter. Completing the suspension is a Ridetech air-ride system with tubular control arms and electronic controls. You even get the option to install a Check Engine Light! Using the Chevrolet Performance controller gives you the benefit of the vast testing labs available to General Motors, ensuring that this controller performs flawlessly with aftermarket components. Short of the external power unit and handheld control unit, everything sits on top of the engine. The harnesses have been designed to the correct length to reach each particular sensor in its factory home.
That's right--multiple spark discharge coils! Aftermarket controllers are an important consideration when using a crate engine. As the crankshaft rotates, the teeth on the reluctor wheel interrupt the magnetic field created by the sensor. Some work with many engines, and some only work with one. With a static tune, the engine runs differently at various elevations. The sensor records these interruptions and sends a signal to the computer. Even though the stock Vortec components work quite well with this era of Chevy truck, most of them were swapped out for high-performance components.

The cooling fans and fuel pump can be controlled through the controller as well with the included out-puts. The only thing limiting the Dominator® Vehicle Management System is your imagination! Reaping the Benefits With our system installed and the setup questions answered, it was time for the moment of truth. Any air leak will cause the sensor to retrieve improper readings and can lead to poor engine performance and ultimately, engine damage if the leak is large enough. In this situation, you need a transmission controller. As Flynn discussed earlier, this system can be the only electronic device in the car, and that holds true even for late-model vehicle owners who are looking to use electronically-controlled transmissions and the like.
This allows huge blade throttle bodies to be very tractable, or allow for small throttle bodies to provide sharp off idle response. In addition, if you change the style of transmission, automatic to manual or vice versa, the tune should be changed in the computer. The boost controller setup is of a similar design. No tuning, no removing codes or parameters—just fire it up. Earlier this year Pro-M Racing released the progressive methanol control and the progressive nitrous control upgrades. You tell it what you want and where you want it, then go out and make a pass, and it corrects itself to work from there.
Both of these components are necessary if you are going to use the stock computer. In addition to the transmission control, drive by wire, and dual wideband oxygen sensor options, Dominator® systems have nearly unlimited capabilities to control any power adder, input, or output you can throw at them. Do yourself a favor and do it correctly, the first time. Up to four stages of nitrous can be run, dry or wet, as well as progressive. Simple tuning changes and adjustments are made fairly easily and quickly show improvements in performance. The user can smooth and modify it, and zoom into smaller sections. Timing can be adjusted for each stage as needed for safe engine operation and traction management.
Most of the aftermarket tuning modules and software are locked, meaning they lock themselves to a particular computer on the first use. V4 introduced advanced tables that allow you to do anything and everything you could imagine Not only is the software amazing, the hardware is very robust Doesn't feel like a cheap piece of junk like a lot of other ecus on the market Every one of the people I have been around that has this efi system has adapted so quickly and made fantastic progress very quickly Can't say enough good things I've had the same dominator ecu since 2014 and never had a problem Buy with confidence and check your local racetracks and you'll see Holley named it the Dominator for a reason, world wide efi domination.

Upper-end handheld tuners are typically comparable in price to the entry-level, home-based software programmers. Looking at the underside of the fuel rails, the system is compact and virtually self-contained within the fuel rail packaging. Photo Courtesy General Motors Other considerations also need to be addressed on some pull-out engines. Reluctor Types It is important to know which reluctor type you have, 24x or 58x.
You can tell by looking at the reluctor wheel sensor: a black sensor is a 24x wheel, a gray sensor is for a 58x engine. How about control a 4L60E transmission as well as the fuel and spark on your street rod? When the 327 under the hood developed a knock, it was swapped rather than rebuilt. This means less time working on a laptop trying to get your engine running at its best and more time enjoying the drive. Short of the external power unit and handheld control unit, everything sits on top of the engine. The controller has several pre-programmed timing curves, along with software to create custom curves and adjust the rev limiters and step retard functions. It takes a lot more effort on our end to make things pleasing.
Transmission Controller If you use an electronically controlled transmission without the stock computer, the engine management may not support the transmission. About Us Holley® has been the undisputed leader in fuel systems for over 100 years. Bottom left - The Drive By Wire screen is where the user can program in a pedal vs. Do yourself a favor and do it correctly, the first time. This home-based software costs a good deal more than a handheld tuner or shipping your computer off, but it has much more flexibility and is likely worth the extra cost in the end.
There is a boost builder function, as well as boost scramble options. Boost can be control vs time, speed, gear, or manual inputs. The other big thing about the Dominator is that we have everything integrated into the one box. It was created to provide excellent driveability under all conditions for a wide variety of combinations. The system is set up to scale for each particular sensor you input, which is identified by part number.
