Introduction

Welcome to the next generation of engine tuning. Baseline is a software built in order to provide for a statistically "perfect" tune; using a STANDARD process. The standardization is a key for this kind of tuning. PPO2 uses the physics involved in engine performance to calculate air flow, fuel and timing information. Since the physical process of an engine is exactly the same for any motor and EMS combo; the same software can be used and re-used on every single engine you will ever own.

The idea behind statistics (be it engine or politics); is to gather a large sample of information in order to make generalizations about the process in question. Luckily; modern fuel injected vehicles produce LOTS and LOTS of data. Each engine sensor works in conjunction with the computer / PCM / brain of the car in order to modify and adjust fuel and spark timing. This process occurs at an almost impossible speed (measured in the milliseconds - .001 second). Each of these feedback loops are saved in the form of an engine log; or history of the motor’s state as it runs. While the calculations to determine the optimal fueling and spark are simple in concept; performing them on a few hundred thousand individual engine states would take a long time.

You save these data logs from your Tunable EMS (Apexi PFC, Hondata, e-Manage, Motec, Cobb Accessport, etc.) and import them as a .CSV file into Baseline. Baseline then calculates the average values for each cell in your fuel map and using those average values; determines the optimal amount of fuel required to meet an Air Fuel Ratio Target that you have specified during the set-up process. Additionally; it will also calculate the fuel burn rate to determine the best time to initiate spark to meet a Target Maximum Combustion Chamber Target.

You can then view the Optimal Fuel and Timing map in Baseline and export them into Excel or print them out and then set up the new tune into your Tunable EMS. You can repeat the process as many times as you like; allowing Baseline to move closer and closer to your targets; each tune is saved individually and can be reviewed at any time. As Baseline continues to revise your tunes on each successive run, it will virtually “learn” your actual injector flow rates, MAF sensor voltage etc - thereby self-calibrating to both your individual vehicle and your sensors.

As Baseline is currently in a Beta mode; some specified features may not be active yet - but each new release will include more features. So be sure to check back often and get the latest downloads if the feature you need is not yet available.
