Product overview


The T4+ is the ideal choice for running a 4-cylinder engine fully sequentially with single variable cam control, single fly-by-wire throttle and single knock control. It can also run 6 or 8 cylinder engines semi-sequentially.


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 up to 1Khz logging 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.
