I have been working recently on the 255kpa limit on the E67 ECMs. This limit is regardless of what linear and offset is entered in. The Reason this limit exists is due to the way that the source gathers the voltage from the sensor and converts it to the kpa value. The Raw Sensor data…

This is a Custom OS change to allow fine tuned control of a supercharger bypass valve. This will work with both the factory LT4 Bypass as well as Smooth boost. It will be configured to be Desired KPA vs Current KPA. This was decided to maximize how well the table worked with the existing OS.…

Big update here. I recently have been seeing a bunch of different performance shops offering Custom OS changes to enable different functionalities in the OS. I took this as a challenge to revive the initiative to get the smoothboost controller to work seamlessly with the GM E92 ECM. In my previous attempt I discovered that…

How do I price products? I am not in the business of gatekeeping calibration information. I want to encourage the community to help each other so we can all get more hp. I do not think these tables should be kept isolated to high end shops with deep pockets. My products are priced according to…

Filling in the blanks, This is a list of each parameter I provide and what benefit it may give to you. Ramp out Torque Rate @ 40Mhz SCIAP Linear and Offset Manifold Volume + BTM disabled by TCS are both available via VCM suite, but I can locate them if requested. Rich Decel Enable Switch…

Figured it was time for a new post. I have been working on upgrading my 2016 SS camaro to have the ZL1 Boost gauge in the main gauge cluster. The only clue i was able to find was that the K56 Module played an important role in making this work. At this point, I did…

Before we get underway, A few Disclaimers. I offer this post as educational informational overview of how to find and define tables. I do not condone disabling any Emissions Equipment or bypassing any features in HPT. Tune at your own risk, I do not take responsibility for any misuse of this information. I do not…

For allowing customers to modify tables that are not natively in VCM Suite, I provide XDF files. XDF files are a collection of parameters that define switches, scalars, and/or tables. VCM can then load these definitions from the XDF file and provide the capability to adjust them. These files are written using ‘TunerPro’ This tool…

This took a long time!! The E92 ECM on the ZL1 and any LT4 engine acts as its own boost controller. It provides a PWM signal to control the boost cutting mechanism. In its native state, the ECM commands 95% (or similar) PWM to allow the supercharger bypass valve to actuate using vaccum. When the…

In HP Tuners there is a boolean for setting the Forced induction type to ‘Supercharger Fitted’. In order to do this, you must have wired in the Second IAT sensor. The ECM uses this to determine the density of the air as it goes through the intake system and uses this to calculate the correct…
