Now flex fuel sensor support is standard on all levels
The Hydra product line is powered by dual 16-bit 25MHz
Motorola CAN enabled processors which provide fast and accurate
control of your engine. The Hydra Nemesis 2.7 plug and play engine
management system comes with everything you need to install and run
the Nemesis stand alone engine management system on an MR2 Turbo. The
system has the following features:
The system sells for $1250 plus shipping. The unit includes:

For an additional $75, the unit can be unlocked for use with an
existing external wideband setup to read in a 0-5V signal with the ability to datalog and use this wideband as the primary lambda source on the ecu. We will need the
calibration curve of your wideband to set up this input properly for you, or at the very least the model of the wideband you have so we can search for this calibration.
Also standard with the Gamma Specification:
For an additional $200, the Epsilon Specification unit will add all
Gamma Spec features plus:
Now available at all specification levels is Flex Fuel sensor support. This can allow for seamless running between E85 and Pump 91-92 octane fuel automatically adjusting boost, fuel, and timing levels for the appropriate percentage of ethanol in the fuel. Requires additional GM flex fuel sensor. This sensor can be purchased separately on our site. Older units purchased before June 2013 may need to pay for the upgrade to flex fuel sensor support.
This unit is only legal for off-road use only and requires
professional tuning to safely operate. Base maps are provided only to
get the engine started and (depending on the specific setup) allow
the car to be operated without boosting.
KO Racing strongly recommends getting the wideband option at
the very least for tuning this setup, or paying to work with an
auxiliary external wideband sensor setup. It is not possible to
properly tune an engine management system without good wideband o2 sensor data.
If you are in need of professional tuning for the Hydra Nemesis,
and can not find a certified tuner near you (look on
www.hydraems.com), Kris Osheim of KO Racing can be flown to your
location for tuning purposes. Contact us here.
NOTE: For different versions of the Hydra MR2 units that have been sold over the years, there are some slight variations in the configuration of the jumpers in the Plug and Play box (the silver lower box). If you change from an early Gen 2, to a late Gen 2, or Gen 3 or any other vice versa change, the jumpers can be reconfigured to match your wiring harness pinout. Please refer to the 3rd picture above for the appropriate configuration. All new units sold since 2012 have the 2012 version PnP Board.
