LAMBDA USA Stage 2.2 represents a groundbreaking advancement in Type S Engine Control Unit (ECU) software. Our mission was clear: to address every known issue and deliver a solution that works seamlessly. Stage 2.2 takes performance to the next level. We have significantly enhanced low-end and mid-range response, delivering a substantial boost in both torque and total power output. Stage 2.2 also provides an exhilarating top-end performance that continues to pull with unwavering consistency, creating a driving experience that is as thrilling as it is reliable. The successor to stage 2.1 also brings forth several improvements and adjustments to our lineup of ECU software. As LAMBDA USA's knowledge of the ECU architecture improves over time, we are able to continue to provide increasingly accurate, high performance, reliable, and feature rich calibrations for the platform. All LAMBDA USA calibrations are built upon the latest post–PGM-FI recall ECU software, ensuring maximum reliability. LAMBDA USA Stage 2.2 retains our one-of-one boost-by-gear integration. This system enables precise control of boost target in specific gears. LAMBDA USA prioritizes drivetrain health by limiting torque output in the launch gears compared to higher gears, helping to reduce stress on the transmission and transfer assembly, this also promotes quicker shifting.
LAMBDA USA Stage 2.2 is on a different level, with thousands upon thousands of hours of stock ECU research, and extensive custom modification, all of our calibrations are built upon our unique custom code architecture that is the basis for our upcoming FlexROM flex-fuel implementation. Stage 2.2 also includes optional quality-of-life features such as Auto Idle Stop (AIS) disable and Variable Cylinder Management (VCM) disable, exclusive enhancements not offered anywhere else. LAMBDA USA Stage 2.2 introduces the true "Knock Retard" logging parameter. In stock configuration, the manufacturer opted to withhold the actual subtractive term to the Ignition Timing equation from diagnostic equipment. In stock configuration, the "Knock Retard" logging parameter is actually an additive term that advances the ignition timing, think, "Dynamic Ignition Advance". Using our advanced ECU logging techniques, we have identified the true "Knock Retard". With Stage 2.2, we give our users the ability to monitor the true "Knock Retard", the actual subtractive term to the ignition timing equation, that is the immediate result of the knock sensor noise index, via scan-tool and even the OEM diagnostic software. Additionally, we have made correction more reactive for any excessive noise, and increased the time it takes for the ECU to re-advance the ignition timing upon interpreted noise. Expect an in depth look into this systems inner workings in the future. This system will prove to be an integral part of our custom tuning ventures down the road, when our mobile tuning system launches. Expect more updates on this in the near future as well.
With this update, we also introduce maximum cooling mode. By revising the 10+ stage radiator fan control curve, we are able to increase the systems sensitivity to heat, we have calibrated a more aggressive fan curve to help keep system temperatures under control as much as possible, and also ramping the curve if intake temperature becomes excessive. With this update, we also made adjustments to the torque based boost command strategy, and the electronic wastegate's open loop lift targets as an improvement to boost targeting accuracy. Once again, we push more towards the most OEM+ experience possible, smoothness is a top priority, and now with numerous adjustments the system will be more inclined to downshift into power rather than attempting to hit its torque command at excessively low rpm. With this update, users will likely notice an improvement in repeatability and top end performance, as well as shifting consistency. This update is free for all existing tune customers!
