Engine Management Multi-Tune Adaptors

This one is for the professional engine management tuner or advanced do it yourself tuner of any of the more commonly adjusted engine management systems--including but not limited to Nissan, Honda, GM, and Ford.  The Multi-tune Adaptor installs into the standard 28 pin ROM socket of your Engine Management Computer or memory adaptor.  It allows the use of a 512k ROM in place of a 256k ROM and has a power input which will switch between the upper and lower half of the 512k ROM.  This allows you to have two versions of software installed and to switch between them on the fly.  The switching is invisible to the engine management computer and because it uses a power input to initiate the switch it can be controlled by another electronic device as well as a simple manual switch.   Common uses are to tune for multiple types of fuels or to tune for a nitrous oxide system.  Multi-tune information page.

Subaru SVX Engine Management Systems

The Subaru SVX sports a JECS engine management computer featuring a Mitsubishi 16 bit RISC processor.  We developed a memory adaptor that can be fitted to  emulate the obsolete memory module Subaru intended to be used and thus update the Engine Control Unit software.  We went a step further and added the ability to switch between two software versions on the fly.  Using this adaptor we offer performance engine management software for the SVX in three stages.  The Stage 1 software for a mostly stock SVX, the Stage 2 software for modified cars with less than 500hp, and the Stage 3 software for modified cars with over 500hp.

SVX Stage One:  Our  Subaru Memory Adaptor programmed with two sets of software, one which greatly improves performance and drivability on premium unleaded and a second variant of that software which allows the use of 87 octane regular unleaded or nitrous oxide.  We've been developing this software specifically to meet the desires of SVX owners as voiced in the forums at http://www.subaru-svx.net/forum/.

SVX Stage Two:  Our performance software package capable of managing 500 horse power.  Stage 2 software is programmed to use the z32 mass air flow meter in order to measure 500hp worth of air and 370cc SR20DET fuel injectors in order to deliver 500hp worth of fuel.  The combination of the larger fuel injectors and mass air flow meter with proven performance tuning for high load ranges provides turn key accurate engine management for modified cars with camshafts, turbochargers, superchargers, etc.  Stage 2v7 also offers tuning for nitrous oxide.  Our flex fuel software Stage 2v7F has the ability to run either gasoline or E85 fuel.
