CAUTION:
The programmer was developed on a stock vehicle with no aftermarket
bolt-on parts; as such, the performance changes implemented by the programmer
may not be compatible with certain aftermarket power add-ons. See below for a brief
explanation of how the tuning may be affected by certain aftermarket devices.
COLD AIR INTAKE (CAI) KITS
Most modern-day vehicles use a Mass Air Flow (MAF) sensor. The MAF sensor is
generally located in the intake tube close to the factory air box. MAF sensors play
a key role in determining the amount of fuel an engine needs at any given throttle
position. MAF sensors are precisely calibrated for the factory intake systems; changes
in intake tube diameter, sensor placement, or filter flow Characteristics can adversely
affect the reading from the MAF sensor. Most of the CAI kits on the market change
intake tube diameter, sensor placement, or filter restriction. These changes may cause
the sensor to command leaner fuel conditions. Most of the CAI kits on the market are
developed on stock vehicles, where a leaner fuel curve may be acceptable. Due to the
fact that the programmer already alters the vehicle’s fueling strategies, CAI kits that
create a leaner condition used in conjunction with a programmer may cause the vehicle
to run excessively lean. Excessively lean conditions can cause pre-ignition which can
lead to detonation, a condition that could potentially damage an engine.
There are currently a large number of CAI kits on the market. These kits are designed
to improve air flow and temperature. Some of these kits may be compatible with
the programmer as is; however, others may cause a lean condition when used in
conjunction with the tuning. If you use the programmer in conjunction with a CAI
kit and you think you are experiencing a lean condition you may need to download a
revised tuning map from Superchips, if available. Please contact Superchips Customer
Service if you believe a CAI map is required for your vehicle configuration.
MECHANICAL MODIFICATIONS
Mechanical modifications such as headers, upgraded camshafts, displacement
changes, cylinder head improvements, etc. will change the airflow characteristics of an
internal combustion engine. The programmer is not tailored to take advantage of these
modifications; for the best results we recommend vehicle-specific custom tuning.
FORCED INDUCTION (TURBOCHARGERS OR SUPERCHARGERS)
Turbochargers and Superchargers drastically change the dynamics/performance of
the engine, and its fueling/timing needs. Additional hard parts and custom tuning are
required to run a forced induction system on an engine that was originally designed as
a Naturally Aspirated (NA) engine. The programmer does not support the addition of
an aftermarket forced induction kit.
