A. The ER HyZor and HyCO 2A are different technologies and react differently to each application.

Generally, the ER HyZor will get about 50% of what the HyCO 2A would get.

They do not get 'more' savings if combined.  

I like the ER HyZor because it is simpler to install, smaller and shaped to fit in tight spaces, less likely to have 'fuel' leaks and has no issues with fuel injection systems MAP sensor.  

The finished installation cost of them both is about the same.

The HyCO 2A does have virtually zero maintenance once installed.

The ER HyZor requires periodic water filling.

Here's a comparison chart.

A. For carbureted vehicles, add the HyCO 2A system only after you get the basic Carburetor Enhancer working.

Often, people find the basic Carburetor Enhancer gives sufficient mileage gains and the pollution reduction for their needs.  In any case, the HyCO 2A won't give any gains until you have a functional Carburetor Enhancer.

The HyCO 2A, installed with the Carburetor Enhancer, with it's electronic upgrade, will often double the mileage of most vehicles (from original mileage). So an example of 10 mpg is now 20 mpg.

For Electronic Fuel Injection vehicles, add the EFIE (on each oxygen sensor before the catalytic converter) and a MAP enhancer (on your MAP and or MAF sensor) before installing the HyCO 2A.   With Fuel Injected vehicles, the gain is often 50% over original mileage.  So 10 mpg would be 15 mpg.

Here is a chart, to help you choose between the HyCO 2A and HyZor technologies.

A. We do not sell HyCO 2A components at this time or for the forseeable future.  We used to but we just don't have enough people to support (purchase, manufacture, inventory, etc) the whole range of products that ER has developed, so lots of billion dollar ideas are just sitting on the shelf.

To solve this problem we are developing manufacturing courses to train people how to make, install and sell these products.

In the meantime, you can build-your-own HyCO system from the instructions in the HyCO 2A Manual.

We recommend you to subscribe to our eNewsletter (using your eStore account) to be informed when we make special short production runs of HyCO 2A kits and when the manufacturing courses will be available.
