GM LT Drive-by-Wire Throttle Body and GM 4L60E and 4L80E Transmission Control

Overview
Take control of your GM Gen V LT1, L83, or L86 engine with Terminator X! Do not settle for a factory ECU with a cumbersome tuning interface when you can have complete control of your engine, self-learning fuel strategies and the proven, race-winning technology of Holley EFI at a budget-friendly price! Terminator X features real-time fuel learn, an integrated 1bar MAP sensor, and four programmable inputs and outputs. The inputs and outputs are ideal for electric fans, boost control solenoids, progressive nitrous control, and much more. Terminator X comes fully loaded with base maps for common LT engine combinations to get you out of the garage and on the road/track fast. The 3.5" touch screen LCD handheld contains an easy to use calibration wizard as well as tuning and gauge display functions. All Gen V LT Terminator X kits will come with an external Gasoline Direct Injection Controller, which enables the end user to control and tune, factory injectors, GM Gen V LT Variable Valve Timing (VVT), and factory fuel pumps. Also included is Holley EFI's industry-leading, easy to use software suite that allows full laptop access for advanced users. Whether you are building, an LT swapped budget beater or a boosted racecar, Terminator X has the features and technology you need at a price that will not break the bank! To identify if your engine is an early or late application, refer to your fuel pressure sensor, located behind the intake manifold. Early sensors have a 4-pin connector, whereas late sensors have a 3-pin connector. This will help you pick which kit you require for your engine.

Not recommended for 4x4 applications with electronic transfer cases. Not compatible with 4L6X transmissions from model year 1995 or before due to year-by-year changes in converter lockup and downshift strategy.

Really indestructible
Color: Yellow
As advertised. I have an obsessed 16lb mixed breed dog that has destroyed everything purchased that says indestructible. Until now... These balls really are indestructible. She loves them and plays with 2-3 at a time. Chews on them and still going. They are the size of regular tennis balls. Others are slightly smaller. These are great and bright... Mooky highly recommends.

A Dog’s REAL Best Friend!
Color: White, Color: White
This ball is truly my dog’s best friend! It is perfect especially for indoor fetch because it’s lightweight (AKA nondestructive!), has just the right amount of bounce, and cannot be torn up by mild to medium chewers. (We have a labradoodle and she isn’t much of a chewer.) It really is bite resistant, and I have a video to prove it! Our dog loves the softness of it. We love that we can throw it around the house without it breaking anything. It almost feels like heavy duty bouncy styrofoam that cannot be picked at or bitten up. We bought the pack and are storing a couple of them for when we someday lose them here and there. I recommend this ball to EVERYone who has a dog and likes to play fetch! FOFOS, pick us for ads! My doggie is obsessed with your product, and I love taking pics and videos of her using it. She’s the type of dog that walks around with a ball in her mouth for fun and comfort. Think of it as her stuffed animal.
