A new software release is available for 3196 engines that are rated at "A" and "B" even though these engines are already in compliance with the IMO emission requirements. Changes include the E-trim for the injectors in addition to the changes that were made to the software for engine ratings of "C", "D", and "E". E-trim allows the ECM to read each injector's four digit code. The ECM will fine tune the injection duration time of each injector with this information, so that all injection times are equal.
The new software for the 3196 Marine Engine can be downloaded from the Caterpillar Web version of the Service Information System. Consult your authorized Caterpillar Marine Engine dealer for assistance.
