A'PEX introduces the first digital fuel computer that combines fuel computer functions with a VTEC engagement controller. The V-AFC features a user-definable, eight-point, adjustable fuel curve that can be set in 500 RPM increments. The range of fuel adjustment is +/- 50% at each of the user-defined setting points. The Fuel Adjustment function considers wide/narrow throttle and low/high camshaft settings, from which four different fuel maps are created (wide-low, wide-high, narrow-low, narrow-high). The integrated VTEC Controller adjusts the point at which the engine switches from the Lo to Hi cam during acceleration, as well as when the engine switches from the Hi to Lo cam during deceleration. Some of the new features include: Completely new case design Compact design Incorporates both AFC and VAFC functions in one unit 16 point fuel correction Color FED display User defined button and background colors Inverted "anti-glare" screen Key functions include: MONITOR MODE- -RPM -Throttle -Battery voltage -Correction % -Air flow % -Pressure -Karmann -VTEC SETTING MODE- -IR map -Air map graph -Throttle point -Deceleration air -VTEC control -VTEC unmatch ETC MODE- Model select Mode select Car select Sensor select Analog scale Warning set Display set Sensor check [gallery] And to make this wonderfulness product available to all of our customers, Treadstone Performance Engineering is now placing the Apexi AFC NEO on sale for the ridiculously low price of 419.99.

As Simple as Pushing a Button, Sort-of! One of the most heart wrenching thing to do to a vehicle when installing larger injectors is wiring. It’s always hard to cut and slice into a pristine wiring harness, the fear of not splicing the electrical connections correctly or the dreaded rewiring when its time to return to stock, but now Treadstone Performance Engineering as the cure to what use to be the most difficult but accentual things to do on a modified vehicle. PNP injector harnesses. Plug n Play adapter, no more splicing and soldering wires, plugs right into factory harness for that OEM look, and you can go back to stock at any time!

In Treadstone Performance's never ending quest to expand our inventory to include almost every possible product desirable to aid in the turbocharging of your vehicle, Treadstone Performance is proud to introduce our investment cast SR20 heat flange. Our casting methods are using the latest in turbocharger-manifold technology with state of the art investment cast process and CAD based techniques. Designed using Solid Works and optimized for ideal fitment and finish, they benefit from an exclusive investment casting method utilizing extremely durable 304 stainless steel. Nissan SR20 Investment Cast Stainless Steel Head Flange. We designed this flange to streamline exhaust gases from a oval port to circular port and match the exact size of our 1.5" nominal weld els. Also we created cut outs on the back side of the flange, not only does this reduce the weight of the flange, but it aids in sealing the flange to the head with approx 35% more sealing pressure. Pressure = Force/area, so if we reduce the area, given the same clamping bolt force, the sealing pressure increased! Never will you have an pesky exhaust leak again. The top of the flange also features a rib that runs through the middle of the flange, this high point in the flange resists warping when welding and maintains a high level if structural rigidity. Our casting methods use the latest in turbocharger-manifold technology with state of the art investment cast process and CAD based techniques.

The Basics: Air Fuel Ratios and Their It’s Importance Introduction: Here at Treadstone one of our main goals is to educate our customers to provide them with the knowledge to safely boost any vehicle they desire. This is why we have decided to introduce “the basics,” which will be a series of blogs that will present information in a simple to understand format with liberal use of lamens terms. Today we will cover the topic of Air Fuel Ratios (A/F) as always we will cover some definitions first. Air Fuel ratios are the amount of air entering the engine in respect to fuel in other words mass ratio of air to fuel present in an internal combustion engine. AFR is an important measure for anti-pollution and performance-tuning reasons. i.e. If your aftermarket A/F gauge reads 12.6, this means that for every 1 part fuel entering your internal combustion engine there are 12.6 parts of air also entering your engine. How They Work? The mechanism in most sensors involves a chemical reaction that generates a voltage. The engine's computer looks at the voltage to determine if the mixture is rich or lean, and adjusts the amount of fuel entering the engine accordingly. Their Importance! As illustrated below AFR play an important part in both economy and performance not only to the after market but to the OEM builders and engineers as well. If you note the picture above shows that maximum power is achieved with a AFR of 12.6:1, this AFR on a turbocharged engine this may lead to per-ignition (knocking/detonation) and server engine damage. Depending on your setup and tune a AFR of 11.5:1 to 12.0: 1 is the maximum recommended AFR a turbocharged engine should see, and should only be achieved with proper tuning methods. Conclusion Whether tuning for economy or for performance keeping a keen eye on AFRs should always be on the top of the priority list. To make sure there is a keen eye on AFRs Treadstone Performance Engineering recommends the use of an experienced and qualified tuner and the use of an after-market AFR gauge.
