Award Winning
Zeitronix Ethanol Content
Analyzer
Best New Racing and Performance Product -
Runner Up - SEMA 2009 and SEMA 2012
First in Flex Fuel since 2008
| Note: A flex fuel sensor is not included with
purchase of the ECA. Sensors are standard
components of many flex fuel vehicles and may be purchased separately at GM
dealerships (GM part number 12568450 or 12570260) or
directly from our order page. |
ECA KIT
We offer new Flow Through Flex Fuel Sensor as a part of ECA Kit, which
includes the Ethanol Content Analyzer, Flow Through Flex Fuel Sensor and ECA
Harness with a correct connector. ECA Kit can be purchased
directly from our order page.
Note than connectors for Flow Through Flex Fuel Sensor and 12570260 Flex
Fuel Sensor are different. We offer both styles. |

What's your ethanol percentage?
The ethanol content of E85 fuel can vary from 60% to 92% ethanol. A fill up with
E85 can drastically change the mix of fuel in your vehicle. For
performance drivers determining actual ethanol content of E85 is essential to
maximizing an engine tune and horsepower. |
 |
Why know your ethanol percentage?
E85 has the equivalent octane rating of 105 octane gasoline. Higher octane
fuel is more resistant to knock allowing for more aggressive ignition timing,
higher compression and increased engine power over gasoline itself. The
Zeitronix Ethanol Content Analyzer helps you get the
most out of your engine and fuel.
Which vehicles have the flex fuel sensors?
A partial listing of vehicles with flex fuel sensors is listed below.
Newer vehicles with the capability for using E85
also use flex fuel sensors. Check for sensors with the following part
numbers: 12568450 or 12570260. A picture of the sensor is given to the
right and dimensions of the sensor are also given below.
What are the sizes of the flex fuel sensor inflow
and outflow lines?
Zeitronix Flow Through Flex Fuel Sensor both tubes are 0.37" and 0.5" at the
flange.
12570260 flex fuel sensor tube sizes are as follows:
Larger (outflow) tube: 0.37" and 0.5" at the
flange.
Smaller (inflow) tube: 0.31" and 0.44" at the
flange.
The usual mounting location for the sensor is the return fuel line.
Always check for fuel leaks.
ECA
Analog Outputs
Ethanol content and temperature analog outputs are available as part of the
ECA. The flex fuel sensor does not provide these outputs. We
have created the ECA to provide these outputs making use of E-85 easier with
after market engine control modules and data logging systems.
