Description – Part of Delphi’s family of
diesel fuel system electronics, the ETC
2.1 controller delivers a wide range of
vehicle- and engine-interface functions in
one compact package. ETC 2.1 is designed
to work with the majority of fuel injection
systems (EUI and EUP) including single- and
2-valve Advanced Fuel System (AFS) tech-
nologies. It also operates without fuel cool-
ing, providing considerable advantages of
reduced hydraulic pipework, reduced leakage
risks, and easier, more reliable mounting.
And, depending upon the customer’s specif-
ic needs, empty- to full-box solutions—from
hardware with I/O interface software only to
complete vehicle and engine application soft-
ware—can be provided.
Building upon two decades of experience in
powertrain electronics, Delphi’s innovative
diesel product line incorporates cutting-edge
technology to help our customers meet
increasingly stringent emission, performance,
and fuel economy demands. We understand
the extended-life requirements for on-highway
vehicles and back our product with a 2-year
warranty. Delphi’s goal is to provide fast,
cost-effective, high-reliability solutions.
