Where Do I Find That Table?

See how different, but similar many tuning packages and OEMs are.  Different software packages, but the same functions exist in there somewhere.  It’s really just the layout and locations that differ the most when you are working on the fundamentals of tuning many applications.

Are All Fuel Injectors Created Equal?

Are all “24#/hr injectors” the same?  Definitely not.  Read this article and learn more about why we sweat the details when changing injectors and making sure the calibration tables get the exact data to match them before we even try to start the engine.

Still not sure how I stand on the debate about unknown injectors?  Read this article and get a better idea of just how wrong things can go if you believe the wrong ASSumptions.

Adapting Fuel Injector Data with a Manifold Referenced Fuel Pressure Regulator

With the release of a whole new batch of fuel injector characterization data for some of our clients, we got some questions from the shops and users. The most popular by far were centered around what to do when converting the fuel system to use a good aftermarket regulator. This article gives solid background and easy answers to the calibration fixes required.

Useless Theory and Boring Math

I had a client ask me to review how their latest calibration data for a popular fuel injector compared to someone else’s data for the same injector. I plotted both against the raw data measured on our flow bench to reveal the differences with cold, hard numbers. Data doesn’t care what you think, it just is.

Rail Pressure Fluctuations and What to do About it

Interesting Things to Investigate over the Winter

Even the pros get stumped sometimes. This time, it’s turbos, boost control, wastegate operation, exhaust backpressure, and a mysterious loss of top end power. Read along as we put a methodical approach to problem solving before blindly throwing money at a problem.

Ignition System Remix

A look at our options for spark delivery and some of the key differences between them. Hosted by our friends over at DIYautotune.com

Winter Investigations Part 2

In the sequel to our earlier article about boost control on the twin turbo C6, we head to the dyno to find out how theory and the real world collide. We also get some bonus data on ethanol with boost.

The ABC’s of DoD

Take a deeper look at how cylinder deactivation functions and learn how it can impact your fuel economy in the article I wrote for Hot Rod Magazine.

Project Pareto

What happens when we sit down to think about where we get the most benefit in adding electronic control? I answer that question in an article over at DIYautotune.com as we look to get the best bang for the buck on engine controls updates, plus a few tuning tips.

The Best Cheat Code for Tuning

Pssst! Hey Kid, wanna learn how to dominate this whole tuning game? This article published by me over at Hot Rod Magazine walks though the details of exactly how we characterize fuel injectors and how to get the right data to drop into your ECU before tuning.

Join Our Lambda Cult

This article was written for our friends at DIYautotune.com to help people embrace the simpler world of using lambda instead of raw air-fuel ratio. Read here to see how taking a moment to change your thinking can save you hours of frustration as you tune your EFI system.

What Happens When you Run Out of Fuel Injector?

Another request from one of my clients to explain the perils of running high injector duty cycle resulted in this white paper. There are a couple of bad failure modes to consider, but they can be avoided with some simple planning and testing.
