It's been fun developing Lupa for STR since returning from Nationals but for the last event of the season, it was time to bring out Bumblestook for one last time this year. We still had over half a tank of ethanol in the tank and practice tires that needed to get all used up before winter hibernation so this would be an all-fun, no-stress kind of event.

The course was fun and fast but with the temps hovering around the high-40s and windy, getting and retaining any heat in the tires would prove to be a challenge. The conditions definitely favored narrower street tires but we wouldn't let that stop us from having maximum fun.

We broke away from the usual 3 heat format to go to a 4-heat A/B/A/B format which we haven't run in this club since the Englishtown days. This was nice because it allowed everyone to get some afternoon runs. We did 3 runs in the morning heats and 5 runs in the afternoon. In the morning, with only 3 runs we barely got the tires to feel even remotely warm but it was good to settle back into Bumblestook's pace. It felt great to be back in the seat of, what for me, sets the bar on how S2000s should drive like.
Andrew and Tamra's Factory Five 818 ("The Bug") unfortunately broke down at the beginning of the afternoon heats. Since we found we had enough fuel left to burn and it was the end of the season, I figured we could share the fun and have them hop in Bumblestook to continue the tradition of the year-end "Beehive". They did well in the car with Tamra, the 2015 CSPL National Champion, kicking my butt in only her 2nd run.

I think this fired Hez up to turn his speed up to 110% and set Fastest Time of Day (FTD) in only his 2nd run in the afternoon and backing it up by going even faster with each subsequent run. I can't wait to see how Hez will do next year after being able to drive Bumblestook for a full season.

We ended the event with just one bar left of fuel left on the gauge (and oddly didn't fuel starve). The tires had well over 150 runs on them and had been stored sub-zero with no protection over last winter which makes Hez's effort to put her into the top spot even more amazing. STR action is definitely fun and we'll see more of Lupa next year but Bumblestook today put an exclamation mark on why her status as the primary "A Team" race car in the stable isn't going to change anytime soon. No worries there, I know where the priority should be.
I can't even begin to describe how much fun it is to drive Bumblestook. The statement "maximum smiles per second" is probably the best way to put it. She puts up a good fight. Sometimes she's on top, sometimes she isn't but one thing's for sure, you don't get out of the driver seat without a big smile on your face and that's what makes it all worth it. I couldn't think of a more perfect way to close out the 2015 racing season.

This post isn't really about Bumblestook but rather her support vehicle, The Egg (Touareg). When I first got the Touareg for towing, I opted to go with the Tekonsha Prodigy RF. It's a wireless brake controller where the brake controller electronics sit in a weather proof box on the trailer itself and you have a wireless controller to set the power. I chose it because it's super convenient and you don't have to mess with the VW electrics but it has a few limitations:
Since the brake controller is on the trailer, I can't actually tow a different trailer if I ever had to since the Touareg effectively doesn't have one installed on it
If you use the hazards, it actually disconnects power to the brake controller as it flashes
It takes up space on the trailer tongue that could instead be used to bring another spare tire! (This is the main reason motivating me to make the switch.)
To address this, I decided to switch to the Tekonsha Prodigy P3 which hardwires into the brake controller wiring already present in the Touareg if you have the factory tow package installed. Why didn't I do this the first time? Well for starters, the Touareg was new and I didn't want to drill anything. I also was weary of the difficulty as many DIY threads on this on clubtouareg.com indicated that the plug would be all the way up in the console and difficult to get to. However, now that the Touareg is a bit older and I have fewer reservations about popping open panels, I figured I'd give it a try.
Important VW wiring to make a wiring harness
To make things easier, rather than splicing the P3 into the factory wiring, it's recommended to instead use some readily available wiring parts from VW to fabricate your own wiring harness. I ordered these from ECS Tuning. You need one 4-pin connector housing (manufacturer part number: 1J0972782, ECS part number: ES311294) and two wires with flat connectors and retaining lugs (manufacturer part number 000979228E, ECS Part number: ES1009146). You cut these two wires in half and you end up with 4 identical length "half-wires" with flat connectors on one end. These four wires go into the four slots in the 4-pin connector housing. I then soldered the other end of these wires to the wiring harness included with the P3 using the following pin diagram and sealed everything with heat shrink tubing. PIN1 - White - Ground PIN2 - Black - 12V PIN3 - Red - Brake lamp signal PIN4 - Blue - Trailer brake output This pin mapping is found in Tekonsha's bulletin on on wiring up their controller for a VW Touaregs and Porsche Cayennes which is available as a PDF online. In that manual it says Pin3 should be connected to a relay but it's been determined by the guys on clubtouareg that for T3 Touaregs (post 2012?), you do not need the relay.

The next part I thought would be the hardest...trying to locate and fish out the OEM brake controller connector under the dash. I was expecting the worst and for it to be all the way up in the A-pillar but instead I got a nice surprise, it was dangling right behind the panel where the ODB2 connector sits. As soon as I pulled the panel (held by two Torx20 screws), I looked up and there was the connector hidden in the foam wrap that I then cut to expose to OEM plug.

The next part was super simple. I just plugged in the male connector from the Touareg to P3 wiring harness I made and mount the bracket for the brake controller under the dash just past my left knee angled up so I can the display and operate it easily. I put the panel back and routed the wiring as much as I could behind the dash and then plugged the wiring harness into the back of the P3. I'll probably clean this up with a wire loom later but for now it works quite well.

Big thanks to Steve at SJF Performance for letting me use his shop to work from and letting me borrow some tools to make the install a bit easier.
