• Introduction

    Hey, I’m William. I put together this store to provide a much needed service to the automotive tuning community. I specialize in Gen V GM Engines that are controlled by the E92 ECU. I have been working to close the gap in what HP Tuners provides and what the community needs to be able to…

  • Factory Zl1 Blower Boost Gauge

    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…

  • How to Develop Custom Parameters

    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…

  • XDF Files and VCM Suite

    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…

  • Enabling Factory Boost Controller

    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…

  • Setting ‘Supercharger Fitted’

    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…

  • SCIAP Sensor configuration

    The work I have done to enable the SCIAP sensor allows much smoother operation of the throttle, and prevents the engine from surging unexpectedly. HP Tuners has added the base configuration of the Linear and Offset to their database, and it can be requested on any specific vehicle. This is not the end of the…
