Here is an Virtual Dyno analysis of a 2nd gear run up for my STS-V. The Virtual Dyno considers the change in speed and estimates the hp & torque, much as a regular dyno. The difference here is that the V is in 2nd gear and pushing against the wind. Read More: http://caddyinfo.com/wordpress/virtual-dyno-vs-delivered-torque-for-engine-output/
Cadillac STS-V Exact Shift Point Testing Posted on May 10, 2013by bwnunnally This morning I made 2 runs to determine current shift points during acceleration from a standing start. I ran the STS-V in “competition mode”; this mode apparently uses “Cruise mode” shifting, which was a surprise to me but means a different table for the transmission logic.

Cadillac Tuning for Results – Shift RPM Posted on May 5, 2013by bwnunnally Engineers spent many hours & iterations to optimize the tune in your Cadillac. But once you make some changes to the configuration and performance of the Cadillac, where is the best tune now? I continue to enjoy Cartest2000 as an analysis tool. This what-if analysis shows a comparison between a modified STS-V with 500 hp using a 6400 rpm redline (shiftpoints, which since the program assumes the automatic shifts at redline become the effective redline) and one shifting at 6800 rpm. The LC3 engine in the STS-V has an actual redline at 6800 rpm, so we are well within the design operating range of the engine. Waiting to shift at 6800 rpm gives a 0.11 advantage in 0-60 time, and a 0.15 advantage in the quartermile. Read More: http://caddyinfo.com/wordpress/tuning-for-results-shift-rpm/
