Ford and Dodge have the deepest coverage in the catalog figures below, followed by Jeep and Chrysler. Start with the diagnosed module and your exact vehicle, then check whether the listing is a replacement or a send-in service.<\/p>\n<p>This page originally listed December 2018 sales rankings. This update replaces those old rankings with catalog guidance by make, model, and module. The counts below describe listings checked on October 23, 2026; they do not rank sales.<\/p>\n<p>Car Computer Exchange has rebuilt, programmed, and shipped vehicle computers since 2011, to more than 150,000 customers across the US. Whether your part is called a PCM, ECM, ECU, or &#8220;car computer,&#8221; the sections below show what we cover and how to match a replacement to your car.<\/p>\n<h2>Key Takeaways<\/h2>\n<ul>\n<li><strong>Our deepest catalogs are Ford (643 modules across 31 models) and Dodge (483 modules across 19 model families).<\/strong><\/li>\n<li><strong>Jeep (210 modules) and Chrysler (195 modules)<\/strong> round out our strongest domestic coverage.<\/li>\n<li><strong>We also cover six diesel platforms:<\/strong> Cummins, Ford Power Stroke, Detroit Diesel, Caterpillar, International, and Dodge diesel.<\/li>\n<li><strong>Check the actual module, not just the acronym.<\/strong> ECU can mean any electronic control unit; some vehicles combine engine and transmission control, while others use separate modules.<\/li>\n<li><strong>Read the exact offer.<\/strong> VIN-programmed replacements, send-in repairs, and cloning orders have different requirements. Warranty and core conditions also depend on the transaction.<\/li>\n<li><strong>Find yours by your VIN and year, make, and model,<\/strong> not by the acronym on the listing.<\/li>\n<\/ul>\n<h2>Use Catalog Coverage to Find Your Module<\/h2>\n<p>Catalog depth shows where you have more listings to check. It does not show which module fits your vehicle or which part has failed. Use your diagnosis, VIN, original part number, engine, and transmission to narrow the choice.<\/p>\n<h2>The Makes We Cover Most<\/h2>\n<p>Our catalog is deepest on domestic makes.

The figures describe listings, not sales or failure rates.<\/p>\n<ul>\n<li><strong>Ford F-Series trucks<\/strong> are our single deepest Ford line, with well over 100 <a href=\"https:\/\/carcomputerexchange.com\/ford\/f-series-trucks-pcm\">F-Series PCM listings<\/a>.

We cover six diesel platforms:<\/p>\n<ul>\n<li><a href=\"https:\/\/carcomputerexchange.com\/diesel\/cummins\">Cummins<\/a> (41 modules)<\/li>\n<li><a href=\"https:\/\/carcomputerexchange.com\/diesel\/ford\">Ford Power Stroke<\/a> (42 modules)<\/li>\n<li><a href=\"https:\/\/carcomputerexchange.com\/diesel\/international\">International<\/a> (43 modules)<\/li>\n<li><a href=\"https:\/\/carcomputerexchange.com\/diesel\/caterpillar\">Caterpillar<\/a> (33 modules)<\/li>\n<li><a href=\"https:\/\/carcomputerexchange.com\/diesel\/detroit-diesel\">Detroit Diesel<\/a> (18 modules)<\/li>\n<li><a href=\"https:\/\/carcomputerexchange.com\/diesel\/dodge\">Dodge diesel<\/a> (25 modules)<\/li>\n<\/ul>\n<p>A diesel engine computer manages fuel injection and emissions functions. On older Ford diesels, the 7.3L Power Stroke also uses a separate Injector Driver Module (IDM). You can browse the full range on our <a href=\"https:\/\/carcomputerexchange.com\/diesel\">diesel page<\/a>.<\/p>\n<p><img decoding=\"async\" alt=\"Diesel modules by platform: International 43, Ford Power Stroke 42, Cummins 41, Caterpillar 33, Dodge diesel 25, Detroit Diesel 18.\" src=\"https:\/\/carcomputerexchange.com\/blog\/wp-content\/uploads\/2026\/10\/diesel-ecm-catalog-by-platform.webp\" \/><br \/>\n<em>International, Ford Power Stroke, and Cummins have the most diesel listings, each with more than 40 modules.<\/em><\/p>\n<h2>PCM, ECM, TCM: Which Computer Are We Talking About?<\/h2>\n<p>Most of the terms you will see for a car computer point to the same part. Here is the short version.<\/p>\n<ul>\n<li><strong>PCM (powertrain control module):<\/strong> runs both the engine and the automatic transmission from one unit. Most of our catalog is PCMs.<\/li>\n<li><strong>ECM (engine control module):<\/strong> controls the engine only. A <a href=\"https:\/\/en.wikipedia.org\/wiki\/Engine_control_unit\" target=\"_blank\" rel=\"noopener\">vehicle&#8217;s engine control unit manages the fuel injection and ignition systems<\/a>.<\/li>\n<li><strong>ECU (electronic control unit):<\/strong> the umbrella term for <a href=\"https:\/\/en.wikipedia.org\/wiki\/Electronic_control_unit\" target=\"_blank\" rel=\"noopener\">any embedded computer that controls a system in the vehicle<\/a>. The engine computer is one ECU among many.<\/li>\n<li><strong>TCM (transmission control module):<\/strong> a separate computer that handles only shifting, used on some models instead of a combined PCM.<\/li>\n<\/ul>\n<p>For the engine computer, &#8220;PCM,&#8221; &#8220;ECM,&#8221; &#8220;ECU,&#8221; and &#8220;car computer&#8221; are used interchangeably by shops, scan tools, and parts catalogs. What actually identifies the right part is your VIN and part number, not the acronym.<\/p>\n<h2>Check What Your Exact Offer Includes<\/h2>\n<p>For a VIN-programmed replacement, confirm the programming included and any work left after installation. VIN programming does not by itself complete key or anti-theft synchronization. Check the vehicle-specific setup before ordering.<\/p>\n<p>CCE describes a 13-point engine-computer testing process. The tests and programming for a specific module or service must match its listing; engine-computer testing should not be assumed for every module type.<\/p>\n<p>The <a href=\"https:\/\/carcomputerexchange.com\/warranty\">warranty terms<\/a> provide a lifetime, unlimited-mile, parts-only warranty covering up to two replacement units during the purchaser&#8217;s ownership of the vehicle. The correct rebuildable core must be sent within 21 days, except where a core charge was applied at purchase or the order was for repair and return. The <a href=\"https:\/\/carcomputerexchange.com\/return-policy\">return policy<\/a> allows authorized returns within 60 days of purchase, subject to the applicable fees and exclusions. Shipping, handling, taxes, and return costs are not refunded.<\/p>\n<p>Repair services require your original module before work can begin. Cloning orders also need the original as a donor. Check the exact listing for the accepted application, service, programming, and warranty conditions.<\/p>\n<h2>How to Find the Exact Computer for Your Vehicle<\/h2>\n<p>To find the right module, match your vehicle, not the acronym on a listing. You will want your:<\/p>\n<ul>\n<li><strong>VIN<\/strong> (your 17-digit vehicle identification number)<\/li>\n<li><strong>Part number<\/strong> from the label on your current module<\/li>\n<li><strong>Year, make, and model<\/strong><\/li>\n<li><strong>Engine size<\/strong><\/li>\n<\/ul>\n<p>The fastest path is to enter your year, make, and model with the <a href=\"https:\/\/carcomputerexchange.com\/\">vehicle picker on the Car Computer Exchange homepage<\/a>, or start from the <a href=\"https:\/\/carcomputerexchange.com\/brands\">browse-by-make index<\/a>. Two modules can look identical and still carry different software inside, so the VIN is what confirms the exact engine calibration, emissions setup, and anti-theft programming your vehicle needs.<\/p>\n<p>If you are not sure which module you need, the team can help by phone using the number at the top of this page, on both the English and Spanish lines.<\/p>\n<h2>Frequently Asked Questions<\/h2>\n<h3>What car computers does Car Computer Exchange sell?<\/h3>\n<p>We list replacement PCM, ECM, and TCM units, plus repair and cloning services. Confirm the exact module, condition, and transaction on the listing for your vehicle. Our deepest catalogs are Ford (643 modules) and Dodge (483), followed by Jeep (210) and Chrysler (195), plus six diesel platforms and smaller catalogs for Honda, Toyota, Lexus, Lincoln, Mercury, Plymouth, and Mercedes.<\/p>\n<h3>Is a PCM the same as an ECM?<\/h3>\n<p>For engine-computer listings, the names can overlap. Some vehicles combine engine and transmission control in a PCM; others use separate modules. Confirm your vehicle&#8217;s actual layout, VIN, and part number before ordering.<\/p>\n<h3>Do your replacement computers need to be programmed by a dealer?<\/h3>\n<p>VIN programming may be included in a replacement offer, but it does not by itself complete key or anti-theft synchronization. Confirm the remaining setup for the exact vehicle and listing. Clone-required and send-in repair orders use different processes.<\/p>\n<h3>What makes and model years do you cover?<\/h3>\n<p>We cover 11 makes and reach well back in model years. The Jeep catalog alone spans 1996 through 2020, and the full range includes discontinued models that are still on the road. Enter your year, make, and model to confirm coverage for your exact vehicle.<\/p>\n<h3>How much does a car computer cost compared with a dealer?<\/h3>\n<p>The listing shows the price for the exact part or service. Compare that with a written dealer quote covering the same vehicle and work, including diagnosis, installation, programming, and any key or security setup. A listed module price alone is not the installed total.<\/p>\n<h3>About Brian<\/h3>\n<p>Diagnosing, repairing, and reprogramming the &#8220;digital brains&#8221; of modern vehicles.
