The Team's Progress on the Tack Project
The team has made significant progress on their tack project, a complex modification that aims to integrate the factory STI speed sensor with the Hahn data cluster. The project began late at night, with the team working tirelessly to get everything up and running. As Dave mentioned, it was meant to be a challenge, but they were determined to succeed.
One of the first steps in the process was to set up the shift notification system, which had been causing issues. They managed to resolve this problem and even added some cool features, such as the ability to show the RPM gauge on the Hahn data screen. The team also worked on the two-step function, which had been malfunctioning earlier. After some trial and error, they were able to get it working correctly, with the car holding a steady two-step for several seconds at a time.
Another crucial component of the project was the boost controller, which allowed them to gradually increase the boost pressure as needed. They also worked on the speedo, which was another key aspect of the modification. The team's efforts paid off when they discovered that they could simply run the wire from the factory STI speed sensor directly into the Hahn data cluster. This allowed the system to read the speed accurately, and the RPM gauge began to work seamlessly.
The Progress with the Boost Controller
One of the key features of the tack project was the boost controller, which enabled the team to adjust the boost pressure gradually as needed. They set the duty cycle to 40% on this component, but ultimately decided to aim for higher levels of boost, possibly up to 22 psi. The goal was to find a sweet spot that would provide optimal performance without over-boosting the engine.
The team's experiments with the boost controller led them to discover an interesting phenomenon. When they took the car down to Nebraska, it was able to peak at 23 psi, which was impressive. However, this also meant that the system needed to be fine-tuned further to avoid over-boosting. The team realized that they had the power and control to adjust the boost pressure precisely, but they still needed to get it just right.
The Challenges with the Two-Step Function
One of the challenges the team faced was getting the two-step function working correctly. They were able to make some progress on this front, but ultimately discovered that it would sometimes malfunction and push through the two-step prematurely. This required them to tweak the system and find a solution.
To address this issue, the team decided to implement a portbou solenoid, which would allow them to gradually increase the boost pressure as needed. This would enable them to make small adjustments to the system without over-boosting the engine. The portbou solenoid was added to the system, and the team was able to fine-tune it to achieve the desired level of performance.
Looking Ahead to the Track Day
Despite the progress they made on the tack project, the team still had some work to do before they were ready for the track day. They were trying to find suitable tires for the car, but ultimately decided to run with the existing set. This was a compromise, but one that they felt would be necessary given the limited options available.
As the team reflected on their progress, they were all impressed by how quickly things had come together. The tack project was a complex and challenging endeavor, but it was clear that everyone involved was dedicated to seeing it through to completion. With everything working as intended, including the RPM gauge and shift notification system, the team felt confident about their chances for success at the track day.
The Brain Behind the Operation
It's worth noting that Emilio had been instrumental in driving the project forward, bringing his creative ideas and expertise to the table. His contributions were invaluable, and it was clear that he was a key player in the team's success. The team's ability to work together and bounce ideas off each other had been crucial to their progress, and Emilio's input had helped to keep the project on track.
As the team packed up their gear for the night, they were all excited about what lay ahead. They knew that there would be more challenges to overcome, but they also felt confident that they had a solid plan in place. With the tack project largely complete, they were now ready to put it all to the test on the track day.
