Multi-Tune Adapters for GM, Honda, Nissan, and more

This is the slickest multi-tune option out there for the tuners of most OBD1 vehicles.   Most 1985 - 1995 GM models, 1986 - 1995 Nissan models, 1990- 1994 Mitsubishi 1G models with eprom ECMs or eprom ECM conversions, and 1988 - 1995 Honda and Acura models utilized 28 pin 8 bit memory devices like the 27c128, 27c256, or 27c512.    The Multi-tune Adapter installs into the standard 28 pin ROM socket of your Engine Management Computer, memcal or other memory adapter--anyplace you would plug in a 27C128, 27c256, or 27c512 ROM.  It allows the use of a 512k ROM (most commonly a 27sf512 these days) 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, connect to boost controllers to allow special tuning at different boost levels, or to wire to nitrous oxide relays to offer all your engine control unit's power to you for tuning your nitrous shot.  Wired to your nitrous relays  it will instantaneously switch to your 2nd tune when your relays open allowing you to put all your fuel in through your injectors or just fine tune your afr with your wet shot, customize your ignition timing, etc., etc.   This is the way to do nitrous right.  Multi-tune information page.

A collection of photos for Subaru SVX enthusiasts!

If you love your SVX you'll truly love this photo album.  You're likely to see photos of things you never knew have been accomplished.  165 HP nitrous systems, custom pistons for high compression race cars, custom pistons for high boost turbo cars, racing engine builds, dyno testing, conversions to JDM drivelines, transmission modifications, and more.  I'm a true SVX enthusiast.  I had big dreams for her from the moment I purchased my first SVX over ten years ago, a south Florida car that's never seen salt, snow, or a fender bender.  Back then there were no performance chips, there was no ability to download the firmware off the control units, none of the information necessary to order performance engine parts had been measured or published, nobody had figured out the weak links of the transmission or developed power packs or through bolted drive gears.  I had to develop all of these things from scratch to make my dreams come true.  Here are some pictures from along the way.

Diagnostics & Subaru Select Monitor Interface

We have designed an interface cable and Windows application which allows us to communicate with Subaru control units.  This allows us to perform all the same diagnostics as the dealer's diagnostic equipment, the Subaru Select Monitor.  It also allows us to download the firmware off of Subaru control units.  We will be releasing a version for your personal use at home soon.
