I have about 100 miles on the new build so far, tuning has gone well and the new install bugs all seem to be worked out. Very happy with it so far. It is much smoother now thanks to the great balance and it winds up a bit faster than before.

Same cam... Bit more compression, bit more dwell because of rod length change and revs faster because of better balance.
The learn table initially asked for some stuff that was pretty strange. We chased it for a while and figured out we were going the wrong way. We found a couple of little things that were contributing to the "strangeness", fixed those and now we are back on the right track getting it real close once again. It's been pretty close all along, we are just fine tuning it trying to make it as good as it can be.
The process basically is to drive the car letting it learn and compensate live, then we look at the learn table once back in the garage and decide how to make permanent changes to the base fuel table etc.

I had my car out on the road yesterday. Weather finally broke and we had mid 70s yesterday morning. I have to say, the new engine LOVED the cooler weather.
After the drive I sent my tuner Andrew the GCF and in true Andrew fashion, he liked what he saw but wanted to "try" a few things differently. He monkeyed around with the air temp enrichment, the AE vs TPS table and some stuff via teamviewer live on the idle. It was fun to mess with it again, been too long since weather was good enough to enjoy tinkering on it.
Today the plan is to pull the oil filter and run it over to the builder so he can cut open and analyze. Hopefully it's all good and I can put a new filter on, top off the Valvoline VR1 20W50 racing oil and go racing next weekend. I'm registered to run local SCCA event on Sept 20.

Lance,
NASA is running at Inde in late Oct. I went to a Proautosports event there last weekend and the weather was pretty good - should be great in Oct. Also went to the new track at Maricopa - Apex. Nice and close, and I will be looking for events there. I'll keep you posted.
Finally got back out on course Sunday after a 7 month long break. Had a blast running our "modified" event, was a bummer to not get too see those that ran the afternoon session but hopefully by next event the restrictions will be lifted.
I was 17th raw time, 18th pax and finished 0.16 seconds out of first place in a packed CAM T class. Pretty happy with that, had a blast racing with James all day for the class win, congrats to him on that.
I've watched all the videos back, multiple times and spent some time talking with others about the course and times and watching other videos. I think I could have got a bit more out of the car with better line choice (keeping the course shorter) and maybe been more aggressive on the start. That said, I still think it did pretty dang well.
The new engine and more importantly the tune fixes REALLY helped increase the mid range power as well as making it pretty manageable to put down. Other than aerating the power steering fluid on my first run, the powertrain performed flawlessly all day.
The only suspension adjustment I made to the car during the run group was to add one round of rear brake bias and then back a half round back out after 1 run. It is amazing to me how just one turn on the knob can change it enough to lock the back brakes up first before the fronts.
Here is my fastest run of the day with the Solostorm data overlayed.
The new version of Solostorm took some getting used to but in the end is MUCH easier to deal with than the older version I was running. I just need to get more of our Region's drivers to start using it so we can compare to each other's runs and all get better. It's an invaluable tool...
