A departure from traditional Holley EFI transmission control, the Terminator X Max ECU allows the ability to use 2007+ GM 6L80E and 6L90E transmissions by communicating via CAN with the internal TCM (Transmission Control Module).  The supplied Holley EFI OBDII Transmission Tuning Handheld is used to adjust Shift Points, Tire Size and Gear Ratio. The Terminator X V3 Software provides the ability to dial in Torque Management to optimize the desired shifting characteristics when using a 6L80\/90E Transmission.  Terminator X V3 software also allows a user to control the Secondary Shift Mode within the Transmission TCM and allows use of Tap Up\/Down Shifting.\n\nWithin Terminator X V3 PC Software\no\tVirtual Torque Management Tables\no\tVirtual TPS Tables to dial in shift characteristics regardless of engine\no\tDBW and Timing torque reduction tables to create smooth shifts\n\nWithin the Holley EFI OBDII Transmission Tuning Handheld\no\tAbility to read and clear TCM fault codes \no\tAbility to raise and lower shift points by MPH or RPM \n\nSupport for Tap Up\/Tap Down Transmission's Secondary Shift Mode\n\nIf you currently have a Terminator X ECU upgrading to a Terminator X Max ECU can be easily done by plugging your main harness into the Max ECU and re uploading your existing calibration\u003cbr\u003e\u003cbr\u003eTerminator X V3 Software is not compatible with Terminator X V1 or V2 ECU Firmware. To use V3 software with an older ECU version, the ECU and handheld MUST be updated to V3 Firmware. Opening a Terminator X V1 or V2 calibration with Terminator X V3 software, will update the calibration from V1 or V2 to V3. A V3 calibration cannot be loaded into a V1 or V2 ECU.  A Terminator X V1 or V2 calibration cannot be used in a Terminator X ECU with V3 Firmware.  \nThe 3.5\" TSLCD can be used to update the ECU the Calibration from V1 or V2 to V3 when using Handheld Firmware V3 Build xx (tslcd35-terx.3.0.xx.fwu) or later.\u003cbr\u003e\u003cbr\u003eFeatures:\u003cul\u003e\n\u003cli\u003eHarness Kit Includes; Main Power Harness, LS1 Main Harness V-8 Injector harness\u003c\/li\u003e\n\u003cli\u003eSimple Installation\u003c\/li\u003e\n\u003cli\u003eWorks with HP or Dominator ECU's\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\u003cbr\u003eDetails:\u003cul\u003e\u003cli\u003eHarness Application: LSX\u003c\/li\u003e\u003c\/ul\u003e\u003cbr\u003e\u003cbr\u003eLinks\u003cbr\u003e\u003ca href=\"https:\/\/www.holley.com\/\/documents.holley.com\/efi_selection_chart62914.pdf\/\"\u003eEFI selection chart\u003c\/a\u003e\u003cbr\u003e\u003ca href=\"https:\/\/www.holley.com\/\/documents.holley.com\/199r10836.pdf\/\"\u003eInstruction Sheet\u003c\/a\u003e","brand":"The Tuner Store","offers":[{"title":"Default Title","offer_id":44810760159318,"sku":"558-500","price":921.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/1772\/8854\/files\/558-500.jpg?v=1780511104","url":"https:\/\/ezbuyco.com\/products\/gm-ls-24x-efi-harness-kit","provider":"EzBuyCo","version":"1.0","type":"link"}
