G4X MONSOONX

MonsoonX

More features, more powerful.

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 100kHz.

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 4Bar MAP sensor further reducing installation cost.

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. 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.

Don’t buy for restaurant industry
Size: 10.5, Color: Black, Size: 10.5, Color: Black
Good looking shoes, fairly comfortable and good value based on the description shared, so I don’t feel it’s fair to rate them lower than 4 stars. I had high hopes for them based on previous reviews from others saying they wore them in the food and beverage industry that mentioned their quality and durability, however I strongly recommend looking elsewhere if you do. I purchased these to wear working in a full service upscale restaurant and in less than two months have managed to have torn the material on the middle exterior section and the bottoms of the shoes are already completely worn down. Good design, but the durability needs to be improved if they’re to hold up for that industry.

DO NOT BUY (lasted less than 7 months)
Size: 11, Color: Black, Size: 11, Color: Black
I bought these for work as a bartender in August of 2025. By December, the tops were scuffed, frayed, and peeling beyond repair, and by February, the soles were coming off. I’ve never had a pair of shoes with such low quality.

Most comfortable shoes, right out of the box!
Size: 8.5, Color: Cognac Napa Leather
Oh my! So, my ordering of shoes online has been hit or miss - 1/2 size too big or too small; too wide or not wide enough. Enter these Marc Joseph shoes… such a game changer. They fit like a glove, exceptionally comfortable, and easy to slip in and out of. I like them so much that I am shopping for another pair. So far, the size, quality, fit, feel, look, and comfort make this pair my dedicated first pick. Btw, I have been wearing them for six hours and they are still very comfortable! I highly recommend these shoes.
