What does a super airflow converter do?

The SAFC Modifies the airflow signal from your Mass airflow sensor. This tricks the stock ECU into thinking more or less air is entering the engine. A useful upgrade if you want to use slightly larger than stock injectors, You can indirectly adjust fuel supply by way of the airflow signal.

What is a safc2?

The A’PEXi SAFC 2 is an electronic fuel-tuning device used to optimize the air-to-fuel ratio in modified engines. Considered a piggyback tuner, the SAFC 2 connects into the engine control unit, or ECU, and modifies the oxygen sensor signal according to your custom settings.

What does a APEXi SAFC do?

APEXi SAFC II Modifies air-flow meter signal (pressure signal in some vehicles) to optimize fuel-air ratio; Vacuum Fluorescent Display (VFD). The second-generation SAFC is a fuel computer that adjusts fuel/air ratio by modifying the air-flow meter/MAP sensor signal.

What is piggyback ECU?

Piggyback tuning Computers/Controllers – Piggyback style controllers intercept signals to/from the factory computer and modify them to achieve the desired tuning result. Used when reflashing is not possible and use of a standalone ECU is not possible to retain required OEM functions.

Does ECU tuning really work?

Sucessfull tunes usually have no downsides and some times even improve fuel economy as they provide more torque lower but you have to be more dilligent with maintainance. In turbo engines if you go for extreme gains you risk the longevity of the engine if not they are ok too.

How much boost can a stock ECU handle?

You can run exactly 0.0 pounds. You can run ~ 11 psi on the stock map sensor once your ecu is chipped.

Are tuners bad for your engine?

ECU tuning does not harm your car’s engine if tuned properly. A good tuning can improve your car’s fuel economy but more often maintenance is needed. However, extreme tuning may affect the longevity of the engine. The engine was not consistently powered and boost delivery felt a little off-timing.

What happens if you don’t tune a turbo?

Unfortunately yes. Car will run fine under normal condition with no tune , but pressing more than half throttle will be lean and not safe. Also, adding the turbocharger is a nice addition to the performance, but lets say that tuning the car with that turbo is what will give you most of your performance gain!

Does tuning shorten engine life?

More horsepower means greater stress for all the units of the aggregate and more wear of the moving parts. However, this does not necessarily mean that tuning will shorten engine life. If done properly tuning will not leave any consequence on the engine other than improving its performance.

Can a tuner mess up your truck?

Can a Tuner Damage My Transmission? Tuners do not damage transmissions, drivers do. Drivers should practice caution and often times reprogram their truck to a lower HP tune depending on the conditions they will be driving in. For example, stock trucks should not be towing on a 120 HP tune.

What’s the operating method for the Super airflow converter?

For the operating method and precautions for the Super Airflow Converter, refer to the Instruction Manual.

Which is Super AI Your Flow converter model?

Page 1 SUPER AI R FLOW CONVERTER SUPER AIR FLOW CONVERTERⅡ WIRING DIAGRAM BY MODEL SUPER AIRFLOW CONVERTER This document describes car models to which the Super Airflow Converter (Product code: 401-A911/401-A913) is applicable, and ECU terminal arrangement drawings.

How do you set RPM on a SAFC 2?

Program the initial settings of the SAFC 2. Use the button controls on the device to navigate to the “NePoint” menu from the main screen. This allows you to set the rpm intervals for fuel tuning, such as one interval at every 1,000 rpm. Navigate back to the main screen, then select the “Th-Point” menu.

How do you adjust fuel on APEXi SAFC 2?

On the SAFC 2 device, navigate to the “Hi-thrtl” menu. Use the adjustment knob to raise and lower fuel-adjustment values at each rpm increment. At increments where you find the air-to-fuel ratio to be greater than optimum value, increase the SAFC 2 fuel-correction value.
