GeneralDisorder Posted November 12, 2019 Share Posted November 12, 2019 (edited) We have been working on this for a bit now, and have several units in the field along with a growing library of base maps for running the OBD-I harness EJ engines (turbo and non) on a plug-and-play LINK ECU. With minor changes to a few pins, and running a vacuum line to the ECU you can be up and running with no codes and modern full programmable stand-alone features in a matter of minutes. LINK developed this board for the V1-2 WRX/STI over in Europe, Australia, and Japan. It happens to share the same basic pinout as the USDM EJ22 and EJ22T cars (Legacy 90-94, and Legacy Sport 91-94). The LINK supports full motorsports features such as: G4+ PlugIn Key Features Up to 6D fuel and ignition mapping Precision closed loop cam control (four cam, independent control) Sequential fuel delivery Digital triggering, all OEM patterns OEM idle hardware supported 5D boost control with three switchable tables Motorsport features - antilag, launch, flat shift Continuous barometric correction (on board) CAN port QuickTune - automated fuel tuning Individual cylinder correction USB tuning cable included Stats recording into on-board memory Gear compensations for spark, boost and fuel Real time selectable dual fuel, ignition and boost maps Sync and crank sensors can be a combination of Hall effect, variable reluctance or optical Boost control referenced to gear, speed or throttle position Up to 32Mbit internal logging memory Staged injection Knock with "windowing" This is the ECU we use for this application: http://dealers.linkecu.com/WRX2Plus Our kits also include a 3-bar map sensor, and the expansion loom for adding inputs such as wideband O2 (highly recommended), fuel pressure, EGT, or any other input you would like to map to an ECU function, alarm output, etc. Included in our package is our dyno derived base map library for the EJ, as well as technical support, and 1 hour of remote tuning assistance to get you up and running and driveable to your local dyno shop or on the street tuning either professionally or personally. The tuning software is completely free and there are no licensing or other fees associated with the software. EVER! You can freely download the latest version from the LINK website anytime even if you don't own a LINK ECU. The software is very user friendly and has amazing documentation - right clicking on just about anything brings up a help window. Tired of those expensive MAF sensors? Throw it away forever. LINK can run speed density, or use any MAF from thousands of other newer vehicles - frequency MAF from an LS? No problem. Throttle body not large enough? Bad TPS? No problem - adapt a newer model. You can change any sensor to anything you like from any make and model supported in the software. Just pull from your choice of car in the junk yard and change a few ECU settings. NO LIMITATIONS. Tired of the limitations of the OBD-I factory ECU? The LINK ECU package with included MAP sensor, XS Loom, basemaps, and remote tuning assistance are $1499 Here's a Dyno sheet from our shop's 1991 Legacy Sport Sedan. This car is 100% stock with only 3" turbo-back exhaust. Factory rated at 165 crank HP on 8 psi. This is @ 16 psi with a LINK ECU, and redline bumped up to 7200: 176.11 AWHP, and 196.17 AWTQ. Corrected for drivetrain losses that's about 210 crank HP from the stock EJ22T with only exhaust mods. Please feel free to contact me either here, or through Facebook or email for any questions, etc. GD Edited November 12, 2019 by GeneralDisorder 3 Quote Link to comment Share on other sites More sharing options...
