Overview
Take control of your LS engine with Terminator X Max! Don't settle for a junkyard 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 Max features real-time fuel learn, high impedance injector drivers, an integrated 1bar MAP sensor, and 4 programmable inputs and outputs. The inputs and outputs are ideal for electric fans, boost control solenoids, progressive nitrous control, and much more. Part number 550-917 also has 4L60E or 4L80E Transmission control. Terminator X Max comes fully loaded with base maps for common LS engine combinations to get you out of the garage and on the road/track fast. These Terminator X kits include a USB/CAN tuning cable instead of the 3.5" Handheld LCD, these kits require the use of the free Terminator X Software for initial setup. The Terminator X Software includes multiple base calibrations to choose from for either naturally aspirated or boosted engines. 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 a budget beater or a boosted race car, Terminator X MAX has the features and technology you need at a price that won't break the bank!

Thin, Light, Very Functional - Fantastic tablet
Color: Gray, Size: 256 GB, Style: Tab A11+, Color: Gray, Size: 256 GB, Style: Tab A11+
First off you only get a tablet, an USB-C to USB-C cable, quickstart instructions and Sumsung care info. That's it. No charger, no nothing else. Even the screen doesn't come with a protector, the tablet itself comes in a fabric/paper like bag. So advice: Buy a screen protector and/or case for this tablet! It's very thin and light weight! The tablet itself is fantastic. It plays all the games so far I threw at it, even the graphic intense ones. Compared to some Chinese ripoffs, this shines like a champ. The 256 gigs of space is plenty and 8 gigs of ram help alot! Truly the tablet is great for my use - Playing games and watching videos. I'm a little upset for the fact that it doesn't come with any charging device, but my phone's charger works fine. The USB-C to USB-C cable may come in handy (but my old PRO12 tablet uses the older usb port). Overall I'm very pleased with it. The games I played on my Moto G phone play fantastic on the A11+ plus it can play much more. Also I don't stream so I put videos on the tablet. My old tablet I had to convert them to make the compatible. The A11+ and Android 16 shines here. It can play most all my videos without conversion, even 4k HDR videos natively! And the sound it great with four speakers as well! Only downfall is the warranty. When I registered the tablet says something about the country of origin so I don't have warranty for the tablet. Just remember to have a charger for it, screen protector and I recommend a case!

Quality but leaves something to be desired
Color: Gray, Size: 128 GB, Style: Tab A11+
The speed and the storage capacity are fantastic. It is not user friendly in terms of being intuitive where certain functions are as compared to the old galaxy. I\nWaste a lot of time searching for where various commands and functions are. They have decided to move them around.\nAnd there is no good search function

All you need in retirement
Color: Gray, Size: 256 GB, Style: Tab A11+
Great purchase in comparison with Fire and the Tab S. Does everything I need it to do: read books, email, pay bills, chat, etc. The price was right and it's a good solid tablet without too much complications. I have a Samsung Galaxy smartphone so both are complementary to each other. One comment, Samsung does not provide an actual plug, just the cable...not the best customer service act for sure but seems like all of them are doing it now. Otherwise, I'm pleased with it.
