SERVICE CENTER AND COMPATIBILITY CAUTIONS
CAUTION: RETURN YOUR VEHICLE TO STOCK BEFORE TAKING IT
TO A SERVICE CENTER. All Edge modules and programmers are built to
operate with OEM calibrations. If you take your vehicle to a service center they
may, by your request or otherwise, update your vehicle’s calibrations. If this
happens and your vehicle has not been returned to stock your device will no
longer be capable of programming your vehicle. Therefore it is important that
you return your vehicle to stock before taking it in for service. Edge updates
its active products (i.e. those currently being manufactured) to work effectively
with updated OEM calibrations. However, this process can take some time as
Edge is not always made aware of calibration changes made by the OEM. In
the case of discontinued products, Edge cannot ensure that your unit will work
effectively if you take your vehicle to a dealership and you are given, by your
request or otherwise, a new calibration.
CAUTION: If you have used another tuner/programmer on your vehicle, you
will need to program the vehicle back to stock and remove the device before
using the Edge Product. Failure to return to stock may result in PCM failure
or engine damage. Programming your vehicle may expose existing defects in
the vehicle’s PCM that could disable your vehicle. It is advised that you do not
program your vehicle in remote locations in case of vehicle failure.
CAUTION: The Evolution programmer was developed on a stock vehicle with
no aftermarket bolt-on parts; as such, the performance changes implemented
by the Evolution may not be compatible with certain aftermarket power add-
ons. See below for a brief explanation of how the Evolution 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 fi lter fl ow
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
fi lter 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 evolu-
tion already alters the vehicle’s fueling strategies, CAI kits that create a leaner
condition used in conjunction with the Evolution 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.
