General Tips
Tip #1
Boomslang harnesses immediately take you to stage 3 wiring, so following tuning tips made for stage 1 and stage 2 wiring won't work exactly as described without other things to consider. See the next tip for better understand.
Tip #2 (observation).
Stage 3 wiring and the greddy CEL adaptor + v2.13 firmware/software caused my car to run lean at low engine loads (360cc I/J before, 550cc I/J after). Experimented using 360cc before and 475cc after made the car run great at low engine loads but then as I approached high engine loads it went rich. Going back to the original 360cc before and 550cc after, I had to richen the I/J map 20% at low engine loads.
Tip #3 (observation).
Greddy has released many firmware/software upgrades, and it's best to start a fresh new map each time. To save time you can open your old map into the new greddy software and perform a select/copy action and then open your fresh new map and paste your old data into there. If you try and load an old map and export it to your EMU funny things will happen such as your airflow corrections mysteriously won't work thus causing you to run rich.
Tip #4 (observation).
Temporarily removing the greddy CEL adaptor on my stage 3 setup made my car run very rich at idle / low engine loads. Keep this in mind if you're comparing greddy maps.
Speed Density Tuning Tip #1
When converting from stock MAF to speed density, your throttle tip in often will run lean momentarily (18 AFR in my case). This should be addressed first by using your I/J fuel acceleration map and add more fuel (ie. 30 to 40%). If you don't take care of this right away, it will make tuning your speed density more difficult.
Speed Density Tuning Tip #2
Don't take the sampling map and copy it verbatim into your speed density map. It can give you a general idea of what kind of numbers you should see, but by no means is it correct. As your RPM increases, your HZ number should increase, as a smooth progression. Likewise, as your load increases (Boost PSI), your HZ number should increase in a smooth manner.
Knock sensor setup
Must be using firmware v2.00 or higher for this feature to work.
Jumper 14: Open
Wire the intake temp/knock signal 2 wire for knock reading. On 91-93 cars it's pin 58, and on 94-97 cars it's pin 78.
In the software knock setup, select intake temp/knock signal 2 and set frequency to 11.38 khz Resonant type. Non-resonant is more sensitive but also picks up too much noise.
Example knock results by tapping engine block with hammer.
