On the way back from the SCCA Finger Lakes National Tour, and have some thoughts on recent changes I thought I'd jot down here.
First off, we tried to up the plug gap and boost, thinking we had fixed our coil issues in DC. We were apparently wrong, which we found out during the Test and Tune day (Friday), so I went back to the drawing board and started looking at my AEM calibration settings. It turns out I had screwed with Pickup Delay Comp to try and reduce timing drift, and it may have been screwing everything up. I also had my Max Teeth for coil dwell set to 15, whereas the writeup on KA-T.org had it at 4.5. I reset everything (Pickup Delay Comp to 0, Max Teeth dwell to 4.5, Min Teeth dwell to 0.05) and now we're getting zero breakup with ignition. Preliminary tests had us boosting at 19psi, which rocked our socks off in a good way. It made a huge difference, as Sunday's course had us banging off the 7200rpm rev limiter (I've heard bad things about 7300, so I try not to cross it).
Secondly, I'm sure most of you have seen that I've recently attempted to correct my roll centers. I can definitely say that they make a world of difference, noticed by both regular drivers (myself and Dave White), as well as our guest driver for the weekend (Todd Keane driving the car in SSM, also from the NER region). The car can now turn in and load up instantly, and throttling on corner exit no longer results in massive inner wheel spin with the helical diff (we'll see how it fares in Toledo on the sticky concrete). Combining this with the newly re-acquired power, the car felt unstoppable.
Which brings me to the results: I'd like to say we did well, but we actually drove pretty poorly. Day 1 started out OK, with Todd spinning on his initial run, but eventually working his way into 2nd place, only 3 tenths off the SSM leader. Dave and I, however, brought a raincloud in with Dave pegging cones on all 3 runs despite blistering fast times, and myself having cones on runs 1 and 2, going for an overly-safe run 1.2 behind the SM leader. Day 2 wasn't much better, with Todd copying my Day 1 performance by coning runs 1 and 2, and settling for a safe run to keep his 2nd place position by a mere hundredth of a second. Dave again had the raw fastest times of the class, but again had cones on all 3 runs. I myself put in a safe run to start with to secure the 2nd spot, but couldn't manage to get a good run in and pulled mediocre times for runs 2 and 3. In the end, Todd finished 2nd in SSM, and myself and Dave finished 2 and 3 respectively in SM.
For the most part, I'm pretty happy with the results, as we've won a couple more Hoosiers in contingency, and we're more confident in the car than ever. This is really good news with the Toledo ProSolo coming next weekend, where our competition will be more than just a BSP prepped car.
Pics and videos to come soon.
