1) ECU must be asleep
before removing TMAP connector. Open hood, lock and close doors, and
wait 15 minutes. If you have comfort access place your keys far
enough away to avoid waking
the ECU up. Alternatively you may disconnect your negative
battery terminal in the trunk.
3) Locate the TMAP sensor on
the charge pipe leading to the throttle body. This is on the driver
side of the engine, below the diverter valves. It can be
difficult to see so use a flashlight to spot
it. Below is a photo with the intake box removed.
4) Once located, use the
flat side of a USB cable to unclip the connector leading to the TMAP
sensor. Push the USB cable up until it stays in place on its
own, and tug the wire
bundle/connector out. Alternatively you may use a penny or
screwdriver to lift the clip. If the
clip is lifted too far it make break. In the event of the clip
breaking plug the JB+ in to the TMAP
sensor without the clip. Friction will hold it in place.
5) Insert the male JB+
connector in to the TMAP sensor so it snaps in place. The dot on the
connector will be facing out to slide under the clip
6) Plug the original male
connector in to the JB+ female connector so it snaps in place. Using a
flashlight to examine the connector ahead of time is a good
7) Installation is complete!
Your car will adapt to the JB+ over the next day or two. So drive and
JB+ Boost Adjustment
The JB+ is adjustable from ~1.75psi over stock, to ~4.75psi over
stock, using the blue
adjustment dial. These figures are averages and actual boost
changes will depend on weather,
altitude, and modifications. But towards the "max" setting
indicates more boost, "min" setting
indicates less boost, and the exact middle is the default
setting. It is suggested users without
access to a BT scanning cable (available at www.burgertuning.com)
use no more than the default
setting to avoid tuner detection codes. If you have access to a
BT/GT1/OPS scanner, or have an
ECU software older than March, 2008, you may run higher
settings. For 91 octane or high
altitude users no more than the 3/4 setting is suggested.
If combining the JB+ with another tune, please consult with that
tuner/manufacturer first for
advice and the suggested settings.
