I'm pretty much done building my LS3. Heads are assembled and on. The only things remaining are to check pushrod length, install rockers/pushrods, and install oil pump and pan.
My current pan is an Fbody pan modified for oil drains and with an Improved Racing baffle. I may sell that with the turbo kit, but not quite sure yet.
The new turbo kit will be very similar and have similar drains, so it'd probably save myself time and money to keep it, but may make selling the turbo kit more difficult.
The DCT guys in Poland sent me a tiny PCB to hopefully improve noise on the DCT speed signals. Turns out it's just a tiny voltage regulator (which came soldered on backwards...) and some pull-up resistors.
From what I was told, the DCT sensors are 2-wire Active sensors and depending on peoples individual setups, sometimes the signal voltage is lower than OEM and the GCU interprets the signal as noisy.
After installing (and modifying) their PCB, NO MORE EMI! The guys at HTG spent several hours remote logged into my laptop and helping troubleshoot and setup Closed Loop tuning.
The closed-loop shifting was pretty impressive. There are some adaptation steps needed at the beginning of setup, but the car learns to shift better and better as you drive the car.
Within 10 minutes, the 1-2 shift was better than I'd ever been able to tune it. I had HTG set up the shift tables to be pretty slow, since I have a heavy rotating assembly and 25# flywheel.
After a couple hundred street miles, I think it can definitely be quickened up. Overall shift feel and speed is much more "OEM" than my DIY tune. My tune had a lot more kick to it, which made it feel more like a sequential than an auto.
Still no road salt here in CT, so I'm continuing to drive the car whenever the weather is nice (less and less often
) I haven't decided when I'll pull the 5.3 and EFRs, but probably mid-Dec. unless the weather takes a turn before then. Even with traction control, road temps below 60F are pretty sketchy.
