What if I said that the best way to tune was to learn to talk to our engines and let them tell us what they like for any given calibration? Now how about if we take it one step further and say this is the ONLY way we will find true and accurate calibrations for our builds? So much so that once we reach a point of a base calibration and are up and running and actually begin the tuning process we should toss out any scribbles we have on paper or beliefs of what a table or cell should look like. And just communicate with our powerplant much like a dr. would communicate with his patient to find out what is wrong. But with even more accuracy and absolutely no guesswork.
Datalogging is our path to listening to our vehicle's demands. And I say vehicle because datalogging can be used to tune more than the engine. It can also assist with shift points, shift times, shift pressures, torque converter lockup engagement and percentage control through PWM, and even trans temps. So powerful is having this ability to record data and time it to other logged data that it is the gold standard of tuning in the industry. And it didn't just become that way, either. Rather it has just matured and flourished into what we all hoped it could one day be. The end all to tuning solutions.
There is little hard calibration data that needs to be known. These are constants. Like injector flowrate. Also engine displacement and firing order. And surface area on the throttle body. A timing map would be good to have but like with the MAF calibration really we just need a starting point there as even that the car will tell us what it wants if we just learn how to ask. And I say ask not listen because I know a lot like to tune by ear and hear how the car sounds. And while to the skilled even this is better than math on paper when it comes to an actual functional real world calibration the simple truth is we designed the computers and the sensors to be far more accurate than we could ever be. These are the tools we made and how they function. And it would benefit some or most here to consider how these new processes might be applied to our older stuff in the name of the tuning perfection that we are all used to on todays cars and struggle so hard to attain on yesteryears stuff that we like to play with.
