HKS F-CON iS

HKS F-CON iS ECU The iS series is HKS's correction / trim only ECU.

It features:
• 4 24x16 INJECTION trim maps (8x in total, for AFM or MAP), for different fuel octane ratings.
• 4 24x16 IGNITION trim maps (8x in total, for AFM or MAP), for different fuel octane ratings.
• 24x16 INJECTION and IGNITION trim maps, for scramble mode.
• 12x8 INJECTION and IGNITION correction map based on throttle change and RPM.
• 24x16 INJECTION correction map, applied by AFR-target map.
• 24x16 AFR target map for wideband-controller feedback correction, applied to the 24x16 fuel trim map.

It also features 2 optional voltage outputs suitable for:
• Airflow.

Injection (fuel) and ignition (spark) trim and correction can be individually enabled and disabled by:
• VPC
• Throttle change correction map
• Scramble map
• GCC (graphical control computer)
• IAT correction map
• ECT correction map
• Fuel trim map A
• Fuel trim map B

The iS series also features a cool feature that does not require having the optional Navigator unit. Basically there is S-Video output to display specs and numbers to a mini-TV, a popular item in Japan and slowly becoming popular in Australia and elsewhere around the world.

Universal - Type-IG: What is this?

This is a special variant of the iS ECU where it supports inputting of already amplified ignition signal from OEM ECU, which contains integrated ignitor. Even though OEM ECU has integrated ignitor, HKS iS ECU requires additional, separate, and external ignitor in order to control ignition in this setup. Also, in majority of cases, the universal harness must be used and patched onto existing OEM harness.

NOTE: Connecting non-IG type iS onto engine with integrated ignitor, or vice versa, will DAMAGE electronic equipment.

Example of applications:
• BMW mini Cooper S
• Suzuki Swift
• Mazda Atenza
