After waiting months for Livernois Motorsports to develop a tune for the 3.0 Continental, I finally gave up on them. Since I was the ONLY person in the world who asked them for a tune, I can't really blame them for not going to the time, trouble and expense of developing one.
So, I have been working with another tuner. His approach required me to attach an SCT tuning device to the ODB port and do a couple of WOT runs, download the info and send it to him. He then analyzed that info, let me know what could be done safely and sent me a tune. We have repeated this datalog, analyze and tweak process 4 times now with each revision getting better. It sounds like a couple more revisions should make it all it can be....safely.
So far, his changes include making sure the drive-by-wire throttle is a actually opening far enough at wide-open-throttle. He has also tweaked the air/fuel ratio to a more ideal setting for my altitude and driving conditions. Ignition timing has been advanced a couple of degrees and the maximum boost has been increased 2 PSI. The transmission tuning has also been tweaked with higher hydraulic pressure at heavy throttle applications.
The result of all this has really transformed the car. The shifts are smooth as silk in normal driving but quick and firm under heavy throttle. Speaking of heavy throttle, it is amazing what the engine tweaks have done. The car is really a rocket, now! I will be going back to the track next week to see exactly how it runs but seat-of-the-pants tells me that it is much quicker than before. My Aeroforce gauge is showing 0-60 in 4.2 seconds which is about .7 quicker than stock.
Based on the current engine parameters, the tuner says he can add 2 more PSI of boost without fear of spark knock as long as I run 93 octane fuel - which is all I have ever used, anyway. I am not sure if the Conti will be as quick as a tuned SHO or my MKS ecoboost but the tuning so far has made the car 100% more enjoyable for me!
