Hilarious forum thread - 1.9sec 0-60.... in reverse
Someone made the mistake of asking an unpopular question.
If you have some time to burn go here and read through this thread. It's frickin hysterical.

DME Almost Fried During Flex Fuel Wire Install
I had a major scare the other day. In the pursuit of speed I decided to upgrade the BMS JB4 unit I have for my N55 engine to have the capability of detecting E85 and adjusting the DME accordingly. It should be good for somewhere around another 40 to 50 hp / tq.
I had to expose the wiring harness of the JB4 unit and first snip two wires. I then had to wire one side together and wire the other side together with an additional sensor that connects to the fuel rail. This sensor has a pin that then goes into a DB25 connector that plugs in to the JB4 unit. Scary stuff. I did everything as outlined in the instructions. I read the thing about 10 times to make sure.
Once all done I tried starting the car. It took a long time to start...then engine light...then dead. After this happened a high pitched ringing sound came from the car speakers until the battery was unhooked. Immediately I had a ball in my throat and felt ill. After quickly disconnecting the battery I rechecked all of my connections. The worst part was that I knew for a fact I had done everything right. The moment you realize everything was done properly is the moment you no longer know what to check next. I emailed the vendor and they quickly got back to me with some things to try. The first round of communications was the usual, making sure I wasn't retarded. During this back and forth I decided to just reverse everything and carefully inspect every part.
It's hard to see in the picture but it shows the problem. The flex fuel add-on module they gave me had one pin that was not completely seated. When connected to the fuel rail it just pushed itself out the back. I pushed on the corresponding wire from the back of the plug and it clicked into place neatly. At this point I was breathing an apprehensive sigh of relief. I still didn't know whether I had fried anything. I was so eager to try this fix that I scratched the shit out of my hand reaching back to the fuel rail connector. I look like a burn victim. I hooked everything back up and the car started up as though nothing had happened. No issues so far but I still haven't driven out of the garage due to weather. I remain confident though at this point. A very scary moment but it's all worth it in the end. It's just part of the ups and downs of what we do. I also learned that every component, no matter how much you trust the vendor, must be inspected very carefully.

State College to Beaver Springs Drag Strip to Centralia Cruise (5/4/13)
*UPDATE*
We have recently found out that the original date that was planned happens to fall on Blue & White weekend which would rule out any chance of meeting near Beaver Stadium. Beaver Springs is not holding Test & Tune day the following week so we are moving the date forward 2 weeks to 5/4.
Warm weather is almost here, finally. I just installed some flex fuel wires and spent my first born on new rims and tires. Still need to fit the intercooler, wheels, and cut a diode for isolated boost control firmware but she's getting close to being ready for the Spring.
We're planning a cruise to the old coal mining town of Centralia that's been on fire since 1963. It's my friends idea and it sounds like it's going to be a blast.
We are going to meet up near the Penn State football stadium for some pictures and BS then we're taking some winding back roads to Beaver Springs Drag Way for a test-and-tune session. It's $40 a car to run and I think it's free to spectate. We'll have to check to be sure.
Here's the meeting spot, marked in yellow, across from Beaver Stadium.
This shows 1 of 2 possible meeting spots in State College and then the ensuing route to Beaver Springs.

2014 C7 Corvette Stingray - First Thoughts and Specs
At first glance you'll notice the same overall dimensions of the outgoing C6. The body looks as though it has been reworked around the same structure almost as though Chevrolet put the new design into the hands of an aftermarket tuner. But keep watching. If you pay close attention to the video as the car rotates behind Mr. Jeuchter it slowly becomes apparent, at least to me, that this not merely a refresh of an old design but a whole new take on the Corvette. The way the hood recesses next to the headlights then bulges around the engine. The way the roof is subtly chiseled, and the way the ZL1ish rear spoiler picks up the lines from the roof and accentuates the angry taillights with menacing black gills. The overall look is growing on me quickly. It's as if they've started with a Ferrari California and stuffed a new Camaro and a last year C6 Corvette inside. If they have finally fixed the Jeremy Clarkson rear bumper flexing issues then I'm sold. Surely out of my budget, but still...I'm sold.

BMW 135i N54 vs. BMW 135i N55: Round 2
I feel as though this debate will rage on with 1 and 3 series owners for years to come. N54 vs. N55. In a previous post 2009 BMW 135i N54 vs. 2011 BMW 135i N55: Round 1 I gave some background and showed a dyno comparison plus a first blood street race result. The information I'm about to spew forth muddies the waters just a tad.
