Sensors

Tangled in the web

While I’m a fan of the hair band song with the same title as this post, removing all the wiring that supports the various sensors and displays on the homebrew gauge panel was an unpleasant tangled web to work through on the Silver S4.

This time with the displays I had a plan to simplify the wiring and de-clutter but it still came out looking like this.

The Dataq logger has been a tremendous addition to the equipment collection enabling the recording of 8 channels of data simultaneously.  It took over the footwell on the passenger side.

Meanwhile getting all the sensor wiring out of the engine compartment was made easier by removing the entire ECU box.

I’m going to hold off on attempting a reinstallation of all these systems into the Avant until I have a good reason to tackle the project.

Avant

It is… alive!

This afternoon I finished putting the major components back onto the Avant and drove it out of the garage under power from it’s new 47k mile engine.

The instrument cluster is out with Speedometer Solutions having the LCD replaced with a new OEM unit so I’ll hold off on driving it until I get the gauges back.

With space freed up in the garage I pushed the Silver S4 in.

Now I’ll be turning my attention to putting the accessories onto this engine and installing it into the Silver S4.

Avant, Upgrade Work

Differential Installed

A couple of days ago the Avant’s rear differential came back from the shop where it was having an MFactory Helical Limited Slip Differential installed.  I set about installing the differential as well as a slightly newer Apikol rear differential mount.

I may finally be at the point where I can begin to put the remaining parts back on the Avant, most notably the exhaust, and start it up with the newer engine.

This round of upgrade work at the rear of the car has seen a set of Stasis Öhlins Motosport Coilovers arrive, 034Motorsport adjustable swaybar endlinks, 034Motorsport rear differential carrier, MFactory Limited Slip Differential, and Apikol rear differential mount, to go along with the already present Neuspeed rear swaybar.
