Welcome to the Official efiHacks Community Wiki.

efiHacks is a site created by efiLabs dedicated to the community of electronic fuel injection hackers. Our goal is to cultivate a community around our electronic fuel injection interceptor control devices that we're developing. This wiki serves as a repository of information for such a community.

Our wiki pages will help you to find almost anything you want to know about the efiLabs products and the handling and operation of it. It also contains lots of techie info about the concepts and inner workings of these high tech marvels.

Also be aware that this is not a sales or marketing page, rather a comprehensive engineering page. You might find some spots throughout the pages where things might seem missing or the page ends incomplete or the wording and formatting is not perfect.
As mentioned engineering, which implies the engineering is being done and the findings or documentation might just not have made it into Our Wiki :) ... we're busy and whenever time and space we will share our engineering progress here.

Currently there are 2 product lines with one being the efiO2Meter tool and accessories and the other being the map based efiInterceptor (aka efiMini) electronic fuel injection piggyback controller and accessories.

The efiO2Meter (Lambda-Meter) is based upon the Bosch CJ125 wide band O2 sensor interface controller IC chip. It has a bluetooth based wireless control interface (SPP) with software Apps based O2 sensor data logging functions. It comes with GUI Apps for the Windows, Linux and Android operating system. ALl of them support wireless as well as RS232 connectivity to the efiO2Meter.

The map based efiInterceptor is a precision realtime electronic fuel injection controller intercepting the stock fuel injector signals and providing a map based timing corrected signal to the injectors. It comes with an extensive windows based GUI control panel and a custom bluetooth-radio dongle with Android, Linux and Windows GUI analyzer panels and data logging functions ...
wireless data logging means i.e. that the android based cell phone or tablet connects to the efiInterceptor bt-radio and is now able to display and log all realtime data. The log size is determined by the memory size of the bt-connected device ... cell phone, tablet, etc ...

Please note, while our products are not suitable for all applications, there is a good chance that it will help you to achieve your goal faster, easier and more economically.

Wireless Wide Band efiO2Meter Tool / Controller Topics

These topics will link you to all the efiO2Meter details available on this efiHacks community website.

This device is also targeted for System-Integration and OEM-Customers in automotive and industrial control applications, since it provides almost every data imaginable through the serial link.
More important, through our modular concept we would be able to react fast and cost-effective to most customer specific hardware and firmware customization demands.

please don't get too excited ... we're still in the developing phase ... efiO2Meter tests will take place mid sept and production units available along with an android app by start of oct ... yes we're moving incredibly fast :) ... but at the expense of the efiInterceptor :(
