GM Injector Characterization

Plug n’ Play Data

Are you tired of pouring over logs, making corresponding changes to your tune, only to find that what worked one day is off by the next? Have you wasted hours sifting through a myriad of injector related forum posts, only to find that there is no simple solution? Such is the nature of tuning with inaccurate injector data.

Accurate injector characterizations are the basis of all fueling calculations, so it’s no wonder that if you’re tuning without them, you will spend a lot of valuable time making the best of a bad situation. It will keep you busy searching for endless combinations of mostly incorrect answers, and it will rob you of the most basic functions provided by the guys who spent millions of R&D dollars designing the engine management system for your car.

Whether you are a professional tuner, or an end user, you can spend countless hours getting it “mostly correct” or you can copy and paste accurate characterization tables and get on with the job of maximizing performance and drivability.
