1 Issued by: Page: David Björklund 1(1) Date: NIRA i7 s NIRA i7 is an engine management system designed by Nira Control AB. This document describes the input, output and communication channels of NIRA i7. For the purpose of clarity, the descriptions are based on a typical application. Even though each has an Example Use listed, NIRA i7 can of course be configured to handle other sensors/actuators than those listed. NIRA i7 is available in three flavors: NIRA i7x for DI/PFI Otto engines, NIRA i7rs for common rail/unit injection diesel engines and NIRA i7rp for common rail diesel engines with piezo injectors. Follow the crosses in the P, S and X columns for availability on NIRA i7rp, NIRA i7rs and NIRA i7x respectively. The specification of NIRA i7 is subject to change as new hardware revisions are introduced. Contact Nira Control AB for updated versions. Nira Control AB, vat no.
