Now that S58 tuning software supports true CAN-based Flex Fuel tuning, we are offering our own plug and play ECA solution! With CAN, there is no longer much of a need for Bluetooth ethanol sensors. A CAN-based ethanol sensor, can not only monitor ethanol content, but it will also directly communicate with the DME for full Flex Fuel operation. With a Flex Fuel tune, the DME will automatically adjust the tune from a high-powered E85 map, all the way to a pump gas map, and everything in between. This all happens on the fly, based on the live CAN-communication with our ethanol sensor. Gone are the days of doing math at the gas pump only to decide which map to flash and how many gallons of ethanol to mix!

ZERO cutting and ZERO wire-taps! This kit is fully reversible and truly plug and play. The wiring integrates into the OEM harness and hoses and sensor tuck seamlessly to allow for reinstallation of all OEM sound insulation foam and engine covers. With the ethanol sensor mounting location as close to the injectors as possible, there is virtually zero lag time on the exact ethanol mixture truly entering the combustion chamber.

Don’t be fooled by our extensive and overly detailed, DIY-friendly instruction manual! You can expect this kit to take about 1 hour to install (depending on skill-level).

  • Zeitronix ECA-CAN Module
  • Custom PTFE Hose Set
  • Dorch Plug-n-Play ECA Harness
  • Genuine Continental Ethanol Sensor

Very Straightforward and Easy to Use
Reload type: One Time Reload
I have used this several times, and it has always been a smooth and convenient experience. The biggest advantage is how intuitive the process is. Reloading the balance is simple, quick, and easy to understand without unnecessary steps or confusion. It is especially useful for managing spending, setting a shopping budget, or keeping funds ready for future purchases. Instead of entering payment details every time, having balance available makes checkout faster and more convenient. I also appreciate how quickly the funds are applied, allowing immediate use once the reload is completed. This is one of those simple Amazon features that works exactly the way it should. Overall, easy, efficient, and user-friendly. I have been very satisfied with it. Five stars.

Easy and simple: Exact Step-by-Step Guide to Reloading Your Balance
Reload type: One Time Reload
I found reloading my Amazon gift card balance much easier than expected. The process was simple and took about 5 minutes at most. Here are the exact steps to do it: ​Login: In the Amazon app or on Amazon.com, log in to your account. ​ Menu: Tap the 3 lines on the bottom right corner of your screen (next to Rufus, Amazon's AI). ​ Find Category: In the section highlighted "Shop by category," tap on Gifting & Registry (3rd option down in that section) and a drop-down menu will appear. ​ Select Gift Cards: On the drop-down menu, tap Gift Cards (first option). ​ Choose Your Action: "The Gift Card Shop" will appear. There you will have three options: "Redeem a gift card," "View your balance," and "Reload." ​ Start Reload: To add funds, tap Reload. ​ Select Type: Scroll down to "Add funds directly to your Amazon Gift Card balance" and tap which reload type you want (one-time, low balance auto-reload, or scheduled auto-reload). ​ Enter Amount: Choose your reload amount. The default is $25, but you can type in your own amount as well (the minimum amount is $5.00). ​ Finish: Tap the orange "Buy Now" tab. ***I used the Amazon app using the u i OneUI version 8.0 these Amazon app on Android version 16 (Baklava) on a Samsung Galaxy S25 Ultra. Others may have a slight variation of the menu setup on the Amazon app.***

Easy way to add balance
Reload type: One Time Reload
Reloading my Amazon gift card balance has been easy and convenient. I like using it when I want to keep a little money set aside for Amazon orders or make checkout quicker without thinking about which card I want to use. The process is straightforward, the balance shows up fast, and it has been reliable every time I have used it. It is also helpful for budgeting because I can add a set amount and then use that balance for regular purchases. Nothing complicated about it, which is exactly why I like it.

Monthly reload for Subscribe & Save Orders
Reload type: One Time Reload
Not a glamorous review, but a genuinely useful tip for Subscribe & Save users. I reload about $100 to my gift card balance once a month, a week or two before my S&S order processes. Amazon pulls each Subscribe & Save item as a separate transaction, which means 10+ individual charges hitting your bank account on before or on ship day. A headache for budgeting and a minor anxiety trigger if you're watching your account for unauthorized activity. Loading the balance first consolidates everything into one clean transaction. Your S&S order then pulls from the gift card balance rather than your card directly, and your bank statement stays tidy. The side benefit is built-in budget discipline. I set about $100 as my monthly Amazon ceiling - if my cart runs over, something gets pushed to next month. It's a simple system that keeps spending intentional without any extra effort. If you're a regular S&S user who wants cleaner finances and less ""wait, who charged this and what was that charge?"" moments, this is worth making a habit.
