Three modes, Economy, Sport, and DSP. I prefer Sport for 01Ms bolted to the ALH, and Economy for those bolted to the gas engines. I find DSP becomes tiresome and confusing and often the TCM struggles to find out when it needs to change between the two.
But in any case, easy to change with VCDS. There are helper boxes that pop up in the TCM coding to tell you what to change. If you drive a lot of highway driving, it will not matter a whole lot, as it will be in 4th+ lockup the whole time anyway, regardless of soft coding.
^Pretty much.
Also, swapping to a manual gets you huge gains in MPGs. Almost seems as if the people I do the swap for get better fuel economy than the cars that can manual from the factory. Maybe the 11 mm pump and smaller nozzles are more efficient when bolted to a manual than the 10 mm and bigger nozzles. *shrug*
I will say that on some later transmissions, I especially noticed this on the 01V bolted to the BHWs, leaving DSP enabled in coding makes for a much better driving experience, especially if you deal with any steep hills. Without DSP, it will upshift much more frequently when you lift your foot off the throttle some, which is often times exactly what you don't want it to do, you want it to hold the lower gear while on that incline because when you make your turn and want to accelerate again it would have to downshift after it already went up a gear.
I experienced that in several instances with one of my BHWs living in a hilly area. When I reverted the coding back to enable DSP, it seems as if it was taking into account the inclination that the ABS/ESP was reporting on CAN and holding the gear appropriately, making for smarter operation from the transmission without my having to intervene in tiptronic mode.
If you live in flatlandia, you won't notice the difference. But living here, I certainly did notice the difference with DSP on.
The 01Ms are a different story, though. There's nothing all that great about their operation. Torque converter? More like torque absorber, amirite??
Well, I guess converter is still accurate... it's converting your torque to heat and noise. lol
