PPEI Diagnostic Review


This is for people wishing to use PPEI’s Diagnostic service to help diagnose issues generally related to tuning and/or aftermarket parts. This is a useful service for shops and customers that wish to have a second opinion on how to bring their vehicle to its full potential. With having viewed over 1,000,000 datalogs in the past 16 years – there is not much that we have not seen. While doing remote diagnostics is rather difficult, we are quite efficient with helping pinpoint what can be improved upon.

PPEI Tuning Customers – This service is already included with the tuning you purchased from us. So unless you just want to buy us some drinks, don’t worry about it 😊

Did you know that PPEI has reviewed over 1,000,000 data logs? 

So, what is a datalog?

PPEI has been reviewing data for vehicle optimization since 2008. So, what is a data log? A data log or datalog also known as a diagnostics log, is a recording of data stored electronically in a vehicle. It can include a wide range of information, such as vehicle speed, engine RPM, fuel consumption, and many other performance-related parameters. Data logs are used for various purposes, including diagnosing problems with the vehicle, improving vehicle performance, and analyzing driving behavior.

Data logging for a vehicle is the equivalent of a person going to a doctor for a checkup. In most cases, you know when something needs to be fixed, but sometimes you only know once it's too late. Data logging can be an effective way to diagnose problems with your vehicle. By analyzing the data recorded in the log, you may be able to pinpoint the cause of an issue and take appropriate action to fix it. As you increase your vehicle's performance, data logging becomes more critical. Data logging can help you understand how your vehicle is performing and identify areas where it can be improved. For example, you can use data logging to see how different driving habits or modifications affect fuel consumption and overall efficiency.

Data logging can provide real-time information about how the vehicle is performing, which can help identify problems as they occur. For example, if the vehicle's engine is running poorly, the data log may show high levels of engine RPM, low fuel efficiency, or other unusual performance parameters. Data logging can also be used to identify patterns in the vehicle's performance over time. For example, if a problem only occurs under certain driving conditions (such as at high speeds or during cold weather), this may be reflected in the data log. By comparing the data recorded in the log with the vehicle's expected performance, you can identify deviations that could indicate a problem. For example, if the vehicle's fuel efficiency is significantly lower than expected, this could be a sign of a problem with the fuel system or another component.

Overall, data logging can be a valuable tool for diagnosing problems with a vehicle's performance, as it provides a wealth of data that can be used to identify and troubleshoot issues. Why is this so important? Because at PPEI, we review data to help you understand how efficient your vehicle is. Many tunes/calibrations on the market are less than "sub-par." What we mean is that it is easy to sell a calibration. However, it is another story when you need the tuner to review the vehicle's information and make adjustments. This is where our 13+ years of studying more than 1,000,000 data logs come into the equation. So no matter what fuel system, turbo, or injectors you are using, PPEI can quickly assess the problem and make recommendations on how to fix it – saving you time and money spent on things that do not resolve your vehicle's issues.

Fast customer service

Y’all I cannot stress this enough, these guys are the best. Literally the best customer service I’ve experienced in a long time. Truck was throwing a MAP code after I flashed it and I sent them data logging and they responded before I even thought about checking my email. Sent over revised tunes and no more code. Truck runs amazing. Thank you!
