Finally got around to remapping the ECU on the IS-F.
Something which has been a huge challenge for many tuners over the years, the ECU has finally been cracked by RR-Racing and last week we loaded a new map which features:
* Modified Direct Injection / Port Injection fuel mapping
* Modified Ignition control (ISF has base ignition maps, cam timing dependent ignition maps, knock correction maps)…
* Modified Intake and Exhaust variable cam maps
* Modified Torque to throttle mapping (allows us to enhance throttle response)
* Modified Rev limit increase to 7200rpm
* Modified CEL parameters (e.g., disabling of O2 sensor warning light)
The verdict? The car is an absolute monster to drive now. It has so much more power all through the rev range and is a definite recommendation to any IS-F owner who wants to extract more potential from the 5L V8 (~480hp).
