It's the 21 century. Engine mods aren't just done with hard parts like camshafts and carburetors anymore. Today's engines have complicated computer management systems that control every aspect from air induction to exhaust flow. The first electronically-controlled engines proved very difficult to hack, and even harder to manipulate without adding some physical hardware.
Since OBDII systems have gone into vehicles, optimizing your truck or 4x4's electronic controls has become something anyone with at least two fingers can do. Programmers that plug right into the OBDII ports found underneath the dashes of most vehicles made after 1995 can be utilized to increase engine power, improve fuel economy, and change transmission shift points.
Superchips is one company that's been in it from the beginning, constantly working on new tuning improvements for almost every type of vehicle you would ever want to tune (including some that we'd never want to own). Just a few years ago, we were still working with bulky tuners that were bigger than a rolled-up newspaper, but now Superchips has introduced tuners like their Flashpaq line that is literally smaller than your hand.
But tuning your engine and transmission isn't only what these programmers do anymore. Nowadays, you can use data acquisition features to see what's going on, read diagnostic trouble codes, recalibrate speedometers, monitor vehicle performance and do data logging. The newer the vehicle, the more vehicle functions you have control of.
We used a Superchips Flashpaq on a late-model Dodge to improve the power and correct some things.
