Apexi el boost gauge install

The control unit can activate the memory replay, warning, and peak hold functions with just one touch. The synchronized memory playback function was designed exclusively so that drivers did not need to individually start each meter before a race.

A high speed CPU processor ensures accurate monitoring every time. The main control unit can accommodate up to 6 meters. This gives the user unprecedented flexibility to decide what type of meter to add and how many. All meters come with a multi-angle stand to allow easy reading from any vantage point. Since the main processor is not inside of the meter itself, A'PEXi engineers were able to slim down the meter casing so that it can be mounted virtually anywhere inside the cabin.

I had already decided to mount the control module in the ashtray well, so I had a minor modification to make to that. After removing the ashtray, I cut a notch in the right wall of the inner housing to provide a spot to run the control module cable: Although the ashtray lamp housing is still attached in this photo, I later removed it, as it was totally unnecessary.

I then installed the control module and ashtray housing back into the console At the rear bulkhead, the control cable connector will fit into its mate, shown here the black pin connector : Once the control module was ready, I turned to the other three components: the pressure sensor, the solenoid valve, and the ECU connections.

I decided to mount the pressure sensor in the unused space below the cruise control unit, in the right rear of the engine compartment.

This is both close to the boost line I wanted to use and relatively cool and protected: First remove the two screws, then remove the cover. Remove the cruise control cable and the three 10mm bolts that attach the unit to the body:.

Disconnect the electrical connector to the cruise control Disconnect the electrical connector for the right rear ABS sensor and to the security alarm horn, and you can pull the harness out of the way to make room for installing the pressure sensor:. This leave plenty of working room, as seen here:.

I cut into the boost line that feeds the stock boost gauge sensor and installed a T-fitting to attach the stock sensor. I then installed a section of vacuum hose from the original T-fitting to the inlet of the APEXi pressure sensor. Here's a photo: The white cylindrical object is a filter on the line leading to the stock boost gauge sensor. The vacuum line at the bottom of the photo leads to the APEXi pressure sensor, and it has its own inline filter.

The pressure sensor was mounted to the wheel housing with two sheet metal screws. It must be mounted with the hose nipple pointing down. The wire harness provided with the APEXi unit was routed to this location, and a ribbed polyethylene sleeve was used for protection from abrasion and heat.
