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!

The inputs and outputs are ideal for electric fans, boost control solenoids, progressive nitrous control, and much more.

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.

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!

Does a good job, and works pretty well. Took weeks to have it delivered.
Works pretty well, seems to be slightly underpowered. I think it would work better if the soil here were drier. The shroud around the blade would probably not jam up with dirt if the soil here is drier. I was constantly having to remove the battery and using a screwdriver to remove the dirt from the shroud. The shroud would work better if it was larger. There is an adjuster that lowers a metal guide that fits up against the concrete that helps you to keep the blade right up to the edge, make sure to lower that guide into place. The 20 Volt Max batteries I used are hard to insert and remove, but mine are aftermarket batteries, and another tool I own is also hard to insert and remove the same batteries.

Good luck with trying to find blades. To work properly one has to find a blade with a center hole of 7/16” diameter OBLONG so it can engage the motor shaft and not spin freely DO NOT BUY THIS REPEAT DO NOT BUY THIS

Make sure you have original DeWALT batteries
Color: Yellow
I thought there was something wrong with the edger but it was the batteries. Must use original DeWALT batteries. I have cheap replacement batteries that work fine for all my DeWALT tools but do not work with this edger. Will run for a few seconds and shut off. With original DeWALT batteries, this edger works great.

Descent tool.
Definitely won't go as far as the add says on a fully charged battery. But works good never the less.
