Engine Changes -
A break down of engine control changes are listed below. Note that each thing is altered or enhanced from 1.04, and our 1.05 tune includes everything from our previous tune(s) (1.03,1.04) enhanced, modified or rewritten for better control.
Throttle airflow scaling and throttle angle scaling has further been fined tuned for better control, response and idle stability. We have further fine tuned the 3D Throttle to torque control tables that modulate how the throttle is opened when you press the accelerator.
What does this mean?
This means you will have better response than 1.04 while also having more stable control at very low engine speeds, which is matched our our new shift changes.
Airflow Control -
We have taken additional time to fine tune airflow and air-load control tables in the ECU, these tables ultimately limit "torque" (throttle angles) in the ECU which can limit power. By changing these tables we have further "unlocked" the ECUs throttle target requests to allow better throttle angles at high load. Note** Torque modulation and control is still present in 1.05 for safety reasons and the ECU will still use the throttle to manage torque as required.
Ignition Control - We have COMPLETELY patched the stock ignition control system with our own "EROM" package that we have implemented in the ECU that allows for finer ignition calibration and a wide range of load ranges which ultimately improve response, mpg and correction for knock events. See below.
Valve Timing Control - We have COMPLETELY patched the stock Valve timing tables with our EROM extended load tables which allow for much finer Valve angle tuning
