Injector End Angle Calculator

This is the ticket for getting smaller displacement engines equipped with large injectors (including the LS) to idle low and smooth when using a Holley ECU. It also can give you improved throttle response, more horsepower, and better fuel economy! (This will not work on a mobile device, sorry.)

Injector Characterization & ECU Data

You will get a download link to your tuning data on your order confirmation page and also by email, once that your payment has been processed. These customized Excel spreadsheets are created for us by Calibrated Success Inc., a top engineering firm. With this data, your ECU will learn everything it needs to know about its new Snake Eater Performance fuel injectors, making it much easier for your engine to perform at its best!


Tuning Help For SEP Injectors

Take a peek inside our Sloppy Mechanics Tune Cabinet! You may know our main influencer, Matt Happel, from the Sloppy Mechanics YouTube channel and Facebook group. Matt has compiled a huge storage database (called the Tune Cabinet) for the ECU tunes he has created for many different builds. Because Matt has probably already built something similar to your project, this info can give you an awesome head start – most of the work has already been done for you!
