Well, were TUNED, virtually, neat story!!
With EFI, strapped on your rig, your able to plug in your pc/laptop, and see everything happening to your engine in real-time. You can capture virtually any data about air, fuel, spark and ignition and on the fly make the finest adjustments. Ok, now the fun part.
I met this guy Rich yesterday (link below) who is a lot like us. Been there for 50yrs, designing, building, racing engines, and has a virtual mechanic service. You get on his calendar, plug in your laptop/pc to your vehicle (its a usb cable) and he connects through your laptop and opens up your vehicles ecu and makes it better... ha..
I called him at 9am, he had me go to a site called team viewer, download a piece of software. You then tell him what your code is and he can connect and remote control your pc.
From here, i connected the cable to my ECU and we began entering in all the global parameters like cam spec, fuel type, fuel pressure, throttle body style, etc. From here we added out tolerances, 34 all in, 15 6500 rpm limit, fan temp on, fan temp off etc... From here he crated a base fuel table, spark table. From here you can get super picky on how quickly you want throttle response, what happens within the millisecond for all of these ingreadiance and can in our case take out lean pop by adding fuel in off throttle scenarios!
Below is a view a pic and video of me at idle, hitting the throttle twice and what the engine did. Although a little small on the video, you can see all the telemetry and how it acts. Ill post more of these as i get it out on the road and you will be able to see real world data...
Anyway, thought it was a great great day knowing we can pull guess work off the table and just drill our best possible performance over time!!
