We also recommend printing all engine parameters to PDF or regular paper, so you have a backup as well.

Most software offers the ability to create this backup, which they may call an image, work order, template, or something along those lines. The other best practice we always recommend is backing up your ECM before making any changes. Our company, Diesel Laptops, manufactures and sells a complete line of bypass and breakout cables for exactly this reason. This would allow you to program ECMs both on the vehicle and on the workbench. While programming through the dash connector may work, it is not recommended unless you pull fuses for all other ECMs on the vehicle.Īlternatively, the best way to program ECMs is to bypass the datalink entirely and connect straight to the ECM. This includes ABS, transmission, GPS, engine, cab controllers, and many more. With today's sophisticated trucks, there is a lot of traffic on the vehicle connectors. The most common reason is that they are doing the programming improperly. Programming ECMs ProperlyĮvery week we have customers that have acquired the ability to reprogram ECMs but run into an issue. The only aftermarket tool we know of that does injector programming on all engines would the one from TEXA, which has the added benefit of no annual fees. While OEM software will work great for programming injectors, the purchase price can be very high, and annual fees add up quickly. For this, the options are much more limited. The other question we ask clients when talking about programming is the ability to program injectors. The TEXA dealer level diagnostic tool can do over 100. For example, JPRO can change around 5 parameters on Cummins engines. You will find a big difference in these aftermarket programs. There are also a variety of tools available to do this that range from OEM software to aftermarket software such as Noregon JPRO, TEXA IDC5, PF-Diagnose, and many others.

There are literally hundreds of parameters that can be set on today's modern electronic engines found in commercial trucks. Examples of parameters that you may want to change:

If you are simply looking to change parameters on an engine, this is not considered programming. Quite often, when customers ask to do “programming”, they are using the wrong terminology. Before we answer that question, we need to dive a little deeper to make sure the customer is asking the right question to begin with. Most often they are referring to engines such as CAT, Cummins, Detroit, Mack, Volvo, International, and others. One of the most common requests we receive from clients is to purchase software in order to program Electronic Control Modules (ECMs) on today's commercial trucks.
