First and foremost, the calibrations in a custom tune are usually much better than a boxed generic tuner. I think most people understand this, but here is where it gets really confusing on several levels.įirst question is, why would we want to use this style of tuning over an off the shelf programmer like we talked about first? There are a few reasons. You have the ability to adjust nearly any aspect of how your engine performs electronically. As you can tell from the menu on the left side there are dozens of these maps that can and need to be adjusted. (This is calculated from other maps like this that take in account throttle position, boost, etc) When the truck is running at 1500 rpm and producing a calculated 300 ft/lbs of torque, the computer will look this value up in the map and set the timing at -1. Across the top axis we have what torque the engine is or should be producing. On the left we have what rpm the engine is running. This table shows us how the computer looks up what value to use for timing. For example here is a timing table from a Cummins diesel engine: We can adjust the parameters in units that relate to what would expect to see instead of odd two character values in strings.

Their engineers have decoded the hex data and plug it into a software that we can look at that makes perfect sense. They provide affordable tuning suites that are user friendly. These programs were not something the average enthusiast would usually feel comfortable using.ĮFI Life, HP Tuners, Sniper/Delta Force, Minotaur, and a few others have changed that. But it was better than nothing and lots of vehicles were tuned this way. While they worked ok, the programs were a bit clunky and hard to use. The programmer companies would sell a tuning suite to dealers who wanted to adjust these programs for custom applications. These programmers work well for a stockish truck. Some will allow you to select what intake you have or perhaps advance the timing slightly, but you really can’t adjust much yourself. The programs are kind of a one size fits all approach because they do not take any vehicle modifications into account. Their engineers use their in house programs to convert this to a form that they can read easier and then they build performance tunes to put in the programmers. The first devices that came out to manage this information were regular programmers that we all know like Superchips, Diablosport, Edge, Bullydog, etc.
If you had to adjust your engine’s parameters using this information as it is, you can see what a challenge it would be for most everyone. This highlighted group might very well be for something like how much fuel the engine is supposed to get at a certain throttle percentage. As you can see in the picture there is a string highlighted.

It is a collection of values that the computer looks up in specific locations for the information about how to adjust the engine for things like timing, fuel quantity, or anything else it has control over it. Let’s see if we can clear it all up.Īll vehicle engine computers run on a programming that uses hex language. There are really a few different ways to tune a vehicle. For the sake of this post, let’s assume we are mostly talking about diesel pickups but much of this applies to the gas world as well. After having a couple of conversations this week about custom tuning, I realized that there is much confusion on what exactly things like EFI Live, HP Tuners, and other tuning suites really are.
