Ideal for 2 - 4 cylinder engines, with a few additional features. 

Part Number: 127-4000

The MonsoonX has been upgraded to provide 512 megabytes of data logging, meaning you can log much more data at a faster sample rate. Control loops are also more precise compared to its G4+ predecessor, along with advancements such as single precision floating point format fuel tables, better resolution within ignition timing and faster communications. These upgrades make the G4X Monsoon a true powerhouse in a small shell.

G4X features 512 megabytes of logging at 32bit using up to 250 channels, each limited to up to 1kHz per channel (by the Operating System), with a maximum of 100 kSamples/sec.

With the MonsoonX you have all the tuning capabilities of the AtomX, but you can also choose to run some of the following features: Launch Control, Anti-lag, VVT Control and Closed Loop Boost Control. It also comes with a built in 4 bar or 7 bar MAP sensor further reducing installation cost. Now featuring Knock Control.

Note: The MonsoonX will run any of the above features, but it cannot run them all at once. The number of features you can run is dependent on how many of the limited Inputs and Outputs each feature needs.

The MonsoonX will control up to 2 rotors or 4 cylinders with sequential injection and direct spark. Or, it can be used for up to eight cylinders using batch fire.

This makes it ideal for naturally aspirated or turbocharged engines that just need a retune and one or two extra features, so you don’t need to jump up to one of our higher-level ECUs.

Best Blue Raspberry energy drink out there!!
Set name: Blue Raspberry
I've tried multiple different brands of energy drinks that have blue raspberry as a flavor. My absolute favorite was the C4 Jolly Rancher Blue Raspberry energy drink..... UNTIL I tried this one. Beats it for sure. It has such a sweet, smooth and refreshing taste and gives a solid boost to power me through my day. The price is a little high but in all honesty it's worth the money! No crash or jitters after one of these and this is coming from someone who drinks lots of caffeine every day. TL;DR absolutely worth a try!!

Great flavor and solid energy boost
Set name: Cherry Limeade
By far my favorite flavor in any energy drink. GHOST really does this one well and the Cherry Limeade tastes great compared to a lot of other energy drinks I’ve tried. Yes, it is high in caffeine, but that’s actually what I need sometimes for a real energy boost, and this one does the job without feeling overly heavy. The calorie content is also great if you’re someone who watches calories, which I appreciate. Overall, great flavor, solid energy, and one of my go-to energy drinks.

Compact snacks you won’t give back!
Flavor Name: Variety, Size: 29 Ounce (Pack of 1)
Super tasty! I actually didn’t realize I could get something like this since most in person stores I’ve never seen these specific combo of flavors together. I personally love the pretzels and getting them in actual lunch snack sizes for work or just to grab for a quick snack on the go is the best thing and makes my day! Perfect size to fulfill a craving and there’s plenty in there even for 2 kids or adults to take to school work or just a tasty on the go snack! Pricing was great for the size and amount of snacks you get and definitely still has that flavorful salty delicious good fish crackers taste while still being fresh and providing that perfect crunch and texture of the regular or jumbo box version.

Perfect Grab-and-Go Snack Variety for Any Day
Flavor Name: Variety, Size: 29 Ounce (Pack of 1)
If snacks had personalities, this box would be the life of the party! The Goldfish Big Smiles Variety Pack is 1 of those rare things that live up to the "variety" promise. You get the classic cheddar (my kid's fav), the colorful ones that somehow make snack time feel more fun, and the pretzels for when you want a little crunch break from all that cheese. The individual packs are perfect for tossing into a purse, lunchbox, and keep some in the car for when the girls get out of school and they are dying for something to eat. Taste-wise - you already know what you're getting: the familiar, slightly salty, slightly cheesy comfort that somehow never gets old. The pretzels add a nice switch-up so it's not repetitive. Only downside? You'll wish the bags were bigger. Every. Time. Overall - it's a solid go-to snack that works for busy days, road trips, or just sitting on the couch pretending you'll only eat 1 pack. Would absolutely buy again (and probably hide a few packs for myself next time).

Goldfish crackers are a family favorite! This variety pack is perfect with cheddar, colors, and pretzels all in individual snack packs. The 30-count box is great value and lasts a while. Perfect for kids' lunchboxes, snacks on-the-go, or just munching at home. They're always fresh and crunchy with that classic Goldfish taste. Love having the variety so there's something for everyone. These are a pantry staple in our house!
