I am new to this list. I got here searching for a way to get the best of both worlds ( for me, anyway). How can I have both the Suncoast 5-6 speed conversion, AND still keep the programmability of the ECU and TCU?
95% of the time, I want lower rpm at cruise, and maximum fuel economy, with earlier upshift and TC lockup. Of course, I still am looking for the option of added performance when I want it.
The problem I am hoping someone has an answer for is how to work around the locked TCU that comes with the 5-6 speed valve body. Obviously, the TCU is a critical part of the conversion.
Regards.
