The T4 can run 4-cylinder engines fully-sequentially or 6 and 8 cylinder engines semi-sequentially. Highlight features on the T4
are traction control, single variable cam control and a CNC machined, billet aluminum enclosure.
T-Series engine control units are powered by an all-new, automotive specific, multi-core processor. They feature Bosch lambda
controllers for maximum accuracy, multiple safety redundancies, high resolution map tables, fully configurable I/O and up to
32MB of logging at up to 500 Hz with compression algorithms for fast log downloads. The PC software has a user-friendly, responsive
design for better readability on high resolution monitors using high scaling (DPI). It features a full oscilloscope for
crankshaft/camshaft signal analysis and allows firmware to be upgraded without special cables or separate software.
