Buying Guide

As a result, you have chosen to purchase an SCT Flash tuner after carefully analyzing your alternatives, consulting with friends, and contacting a few retailers. So, the next crucial issue is: what in the world should I choose? Let us help you get to your destination with a quick and dirty tutorial, so you don’t lose your mind from confusion just yet. There are numerous things that all SCT tuners share, despite the fact that each one has unique bells and whistles.

One of the most frequent inquiries, “Which tuner do I need?” We ask our customers “What features are they interested in” in order to assist them in selecting the best programmer for their needs.

“Do they wish to use the device to gauge their vehicle’s performance, or do they need to data log their vehicle? Are they planning to program their car and then put the tuner in the trunk, or do they want to keep an eye on the OBD-II data while they’re driving? They possess a smartphone, right? Are they keen on a wireless remedy? What is the spending plan? Choosing an SCT tuner takes into account each of these factors.

Pre-Loaded Tunes & Customizable Settings

This means that there is no need for the additional cost of a custom tune if SCT supplies dyno-tested, configurable strategy tunes for your car. For popular air intake improvements, SCT has even created unique tunes to further boost horsepower. SCT tuners come to provide a pre-loaded tune option, with the exception of the X3, which is only intended for custom tunes.

SCT’s pre-loaded tunes have the advantage of being easily adjustable; among the many custom options available, axle ratio, tire size, speed limiter, WOT fuel, and idling speed are some of the most widely used features.

Special tuning

A custom tune is a way to make the most of the added horsepower from your car’s upgrades. Authorized SCT tuners are able to produce a tune using their prior tuning knowledge for standard modifications or even a remote tuning session for extreme modifications like turbos and superchargers. The tuner will send you a tune file through email after one has been made so you may load it onto your SCT device.

custom tunning

With the exception of the TSX, each of SCT’s tuners has a maximum storage capacity of three custom tunes. Let’s imagine you have a nitrous system installed in your daily driving and you use race gasoline at the track. The nitrous tune may be uploaded from the track in a matter of minutes, and for the drive home, you can reset the car to stock (or another street-friendly tune). The vehicle’s original tune file is safely retained in the SCT device thanks to a “Return to Stock” option.

User Adjustable Options are features included in many custom and pre-loaded tunes that let you change a variety of the engine’s (and vehicle’s) parameters. There are options for the octane of the pump gas in the car, the temperature at which the fans should turn on, and even the rear-end gear ratios. Also, you can limit the speed or RPM, advance or retard timing, and add or subtract fuel while the throttle is wide open.

Diagnose Error Codes

The ability to read and clear Diagnostic Trouble Codes (DTC) from the vehicle’s PCM is another one of the common choices. This is a fantastic tool for examining and erasing any potential issue codes.

Data logging and Sensor Inspection

The ability to monitor and log data is the final similarity. These features are essential for giving tuners access to useful data. Moreover, data logging can be useful for tracking the engine’s performance during a run at the track by keeping track of parameters like the air/fuel ratio, coolant temperature, and air intake temperature.

By connecting the tuners to one of the four analog ports, the tuners can also monitor data from outside sources. If you have a wideband or EGT sensor, for example, all you need to do is connect the sensor’s 0–5-volt output wire to the tuner’s analog port, and it will record all the data you need, which you can then view on the screen or upload to a computer.

It is important to check with the dealership or manufacturer before using an SCT tuner if you are concerned about the warranty implications.
