(03-18-2009, 09:13 AM)GREASY_BEAST For simplicity, I could see the benefit of adding electronic rack control to an engine that was in a vehicle with a manual transmission for purposes of removing the vacuum system. This would allow for some fancy computer tricks like a loop that keeps the EGTs from getting too high ("limp mode?"), optimization for performance or economy with the flip of a switch, basically a variable ALDA on steroids. But would it really be that much better than the ALDA?
Why not an automatic? Electronic rack control (like on the OM606) makes all kinds of sense... especially on a SuperTurbo. Right now the Finns have to limit low end torque so that the higher RPM torque doesn't break the crank. That is due to the limits of a mechanical IP governor. With an electronic rack you could load up the torque to the 400 lbft limit at a lower RPM, and continue to limit it throughout the RPM range. That'll give you a whole lot more power, and a dyno plot similar to the modern diesels.
Electronic VNT/VGT control is really the way to go... there are a whole lot of useful tricks you can't pull off with a mechanical controller.

'05 E320 CDI - 118k - Faaaaaast!!
'87 300TD - 317k - Cracked head... but an OM606 is on the way!
'79 300SD - 295k - Bad engine = project car!
