All images from screen captures.\\n\\nJust like with your home computer, proper installation is vital to ensuring you get consistent and reliable service for the life of your Holley ECU. Holley says that properly installing your ECU means mounting it and hooking it up to the vehicle\\u2019s electrical system correctly. Let\\u2019s take a look at what Holley recommends.&quot;,&quot;itemprop&quot;:&quot;image&quot;},{&quot;src&quot;:&quot;https:\\\/\\\/www.racingjunk.com\\\/news\\\/wp-content\\\/uploads\\\/2016\\\/12\\\/Mounting.jpg&quot;,&quot;id&quot;:&quot;34130&quot;,&quot;title&quot;:&quot;Mount the ECU Correctly to Ensure Long Life and Reliability&quot;,&quot;alt&quot;:&quot;Installing a Holley ECU&quot;,&quot;caption&quot;:&quot;Left: Find a suitable location for the ECU that isn\\u2019t going to bind the connectors or subject the ECU to being splashed with liquids for prolonged periods. Center: Use painter\\u2019s tape to mark the mounting holes for drilling. Right: Use the nylon insulators and supplied stainless hardware to mount the ECU. \\n\\nThe main thing to remember when choosing a mounting location is to make sure you don\\u2019t choose a location that will have the ECU immersed in water. After that, you need to make sure that it\\u2019s securely mounted to something sturdy, like the bulkhead or inner fender. Finally, make sure that you fully isolate the body from the ground using the nylon washers and isolators supplied.&quot;,&quot;itemprop&quot;:&quot;image&quot;},{&quot;src&quot;:&quot;https:\\\/\\\/www.racingjunk.com\\\/news\\\/wp-content\\\/uploads\\\/2016\\\/12\\\/Wiring-Comparison.jpg&quot;,&quot;id&quot;:&quot;34133&quot;,&quot;title&quot;:&quot;Power and Ground Directly to the Battery&quot;,&quot;alt&quot;:&quot;Installing a Holley ECU&quot;,&quot;caption&quot;:&quot;These two images show the wrong way (Left) and the right way (Right) to hook up your Holley EFI ECU \\u0026#8211; directly to the battery. \\n\\nI know many of you out there use distribution blocks and lugs when hooking up electronic components in your car. That\\u2019s fine with things like AC compressor clutches, nitrous solenoids, line locks, trans brakes, and the like. However, it isn\\u2019t OK when you\\u2019re installing sensitive digital electronic components like an ECU.&quot;,&quot;itemprop&quot;:&quot;image&quot;},{&quot;src&quot;:&quot;https:\\\/\\\/www.racingjunk.com\\\/news\\\/wp-content\\\/uploads\\\/2016\\\/12\\\/Side-Post-Batteries.jpg&quot;,&quot;id&quot;:&quot;34132&quot;,&quot;title&quot;:&quot;Watch Out for Transient Voltage&quot;,&quot;alt&quot;:&quot;Installing a Holley ECU&quot;,&quot;caption&quot;:&quot;Don\\u2019t use a \\u201cbolt you found\\u201d to hook up the power connections if you\\u2019ve got a side-post battery. Get these side post extensions to do the job correctly. \\n\\nAll these other components can cause large transient voltage spikes, and if you don\\u2019t have your ECU connected directly to the battery, the spikes will enter the ECU and damage or destroy it when they occur. The battery acts like a buffer, absorbing these transients before they have a chance to damage the ECU.&quot;,&quot;itemprop&quot;:&quot;image&quot;},{&quot;src&quot;:&quot;https:\\\/\\\/www.racingjunk.com\\\/news\\\/wp-content\\\/uploads\\\/2016\\\/12\\\/Crimp-Tool.jpg&quot;,&quot;id&quot;:&quot;34124&quot;,&quot;title&quot;:&quot;More Wiring Considerations&quot;,&quot;alt&quot;:&quot;Installing a Holley ECU&quot;,&quot;caption&quot;:&quot;Always use a crimp tool when crimping solderless connectors. Also, always align the connector in the crimp tool with the split in the connector toward the saddle in the tool, not toward the nipple. \\n\\nSome of us may want to mount our Holley ECU inside the passenger compartment. That\\u2019s fine; it comes with more than enough wiring length to accommodate this. Just make sure of the following:\\n\\u2022\\tBe careful when drilling through the bulkhead for the wiring harness to make sure you don\\u2019t drill into something like your heater core\\n\\u2022\\tMake sure  you deburr every hole that you drill before running wires through it\\n\\u2022\\tUse some sort of grommet to protect the wiring and make sure you use the right size grommet. In other words, don\\u2019t cut a larger grommet down to fit.&quot;,&quot;itemprop&quot;:&quot;image&quot;},{&quot;src&quot;:&quot;https:\\\/\\\/www.racingjunk.com\\\/news\\\/wp-content\\\/uploads\\\/2016\\\/12\\\/Wiring-Penetrations.jpg&quot;,&quot;id&quot;:&quot;34134&quot;,&quot;title&quot;:&quot;Keep it Smooth&quot;,&quot;alt&quot;:&quot;Installing a Holley ECU&quot;,&quot;caption&quot;:&quot;Always use the proper size grommets when running wires through penetrations in metal. Also, be sure to deburr the holes before installing the grommets. \\n\\nAnother important consideration is the use of the correct tool for the job. Most of us will grab whatever\\u2019s most handy to turn a nut or bolt. We\\u2019ll grab whatever \\u201csqueeze tool\\u201d is closest at hand when crimping solderless connectors. This is wrong and just asking for a weak connection. Use a wire crimper for connectors and make sure the split in the connector sits in the saddle of the crimper. Line the split in the connector up with the tip of crimper and you\\u2019re just asking for a failed connection.&quot;,&quot;itemprop&quot;:&quot;image&quot;},{&quot;src&quot;:&quot;https:\\\/\\\/www.racingjunk.com\\\/news\\\/wp-content\\\/uploads\\\/2016\\\/12\\\/ECU-Inputs-Outputs.jpg&quot;,&quot;id&quot;:&quot;34127&quot;,&quot;title&quot;:&quot;Holley\\u2019s ECUs are Tunable for Street and Strip&quot;,&quot;alt&quot;:&quot;Installing a Holley ECU&quot;,&quot;caption&quot;:&quot;With a little practice, you can use the Holley EFI ECU to control a variety of outputs such as line locks, trans locks, nitrous solenoids and more. \\n\\nAn EFI ECU (Electronic Fuel Injection Engine Control Unit) uses a variety of sensors to control the flow of fuel into your engine. These sensors can include MAP\\\/MAF sensors and oxygen sensors. When you make changes to your engine\\u2019s fuel delivery system, the stock ECU will take a few minutes to adjust to the new engine parameters. A Holley EFI ECU will do the same thing. Unlike a stock ECU, the ECU that comes with Holley\\u2019s newest EFI systems can be tuned using a handheld controller.&quot;,&quot;itemprop&quot;:&quot;image&quot;},{&quot;src&quot;:&quot;https:\\\/\\\/www.racingjunk.com\\\/news\\\/wp-content\\\/uploads\\\/2016\\\/12\\\/ECU-Air-Fuel-Ratios.jpg&quot;,&quot;id&quot;:&quot;34125&quot;,&quot;title&quot;:&quot;You Can Program Preset Ratios&quot;,&quot;alt&quot;:&quot;Installing a Holley ECU&quot;,&quot;caption&quot;:&quot;There\\u2019s even a function in the control software that allows you to preset a stoichiometric air-fuel ratio so the computer will \\u201clearn\\u201d the parameters required to maintain that ratio.\\n\\nThis means you can customize your engine\\u2019s tune without a computer or scantool. Simply grab the handheld touchscreen remote, bring up the screen you want and modify the settings or pick from a number of presets. If you\\u2019re running an oxidizer like nitrous, the touchscreen control lets you fine tune the engine to get optimum performance out of it. The Terminator and Dominator systems also allow you to have the computer automatically control your nitrous system. This is something a stock computer can\\u2019t do.&quot;,&quot;itemprop&quot;:&quot;image&quot;},{&quot;src&quot;:&quot;https:\\\/\\\/www.racingjunk.com\\\/news\\\/wp-content\\\/uploads\\\/2016\\\/12\\\/ECU-GM-Trans-Control-Page.jpg&quot;,&quot;id&quot;:&quot;34126&quot;,&quot;title&quot;:&quot;Maximize Results&quot;,&quot;alt&quot;:&quot;Installing a Holley ECU&quot;,&quot;caption&quot;:&quot;You can even use the Holley ECU to gain finer control over your GM transmission than the stock ECU gives. \\n\\nA stock ECU will require a computer with the right software and connection to the car\\u2019s diagnostic port in order to do this; plus, you\\u2019ll have to know how to use the software to get the most out of your strip burner\\u2019s engine.&quot;,&quot;itemprop&quot;:&quot;image&quot;},{&quot;src&quot;:&quot;https:\\\/\\\/www.racingjunk.com\\\/news\\\/wp-content\\\/uploads\\\/2016\\\/12\\\/Battery-Connections.jpg&quot;,&quot;id&quot;:&quot;34123&quot;,&quot;title&quot;:&quot;Careful With Battery Connections&quot;,&quot;alt&quot;:&quot;Installing a Holley ECU&quot;,&quot;caption&quot;:&quot;&quot;,&quot;itemprop&quot;:&quot;image&quot;},{&quot;src&quot;:&quot;https:\\\/\\\/www.racingjunk.com\\\/news\\\/wp-content\\\/uploads\\\/2016\\\/12\\\/Rubber-Isolator-Feet.jpg&quot;,&quot;id&quot;:&quot;34131&quot;,&quot;title&quot;:&quot;Remember Your Isolators&quot;,&quot;alt&quot;:&quot;Installing a Holley ECU&quot;,&quot;caption&quot;:&quot;&quot;,&quot;itemprop&quot;:&quot;image&quot;},{&quot;src&quot;:&quot;https:\\\/\\\/www.racingjunk.com\\\/news\\\/wp-content\\\/uploads\\\/2016\\\/12\\\/Explaining-Voltage-Transients.jpg&quot;,&quot;id&quot;:&quot;34128&quot;,&quot;title&quot;:&quot;Voltage Transients Can Be Trouble&quot;,&quot;alt&quot;:&quot;Installing a Holley ECU&quot;,&quot;caption&quot;:&quot;&quot;,&quot;itemprop&quot;:&quot;image&quot;}]\" itemscope itemtype=\"https:\/\/schema.org\/ImageGallery\"><\/div>\n","protected":false},"excerpt":{"rendered":"<div class=\"mh-excerpt\"><p>Just like with your home computer, proper installation is vital to ensuring you get consistent and reliable service for the life of your Holley ECU.<\/p>\n<\/div>","protected":false},"author":28,"featured_media":34129,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":true,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2}},"categories":[5013,11,3470,4879],"tags":[4892,1513,4800,1074,41,4888,282],"class_list":["post-34122","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-electronics-wiring","category-how-tos","category-news","category-slideshow","tag-galleries","tag-holley-performance-products","tag-how-tos","tag-mike-aguilar","tag-news","tag-slideshow","tag-tech-tip"],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"https:\/\/www.racingjunk.com\/news\/wp-content\/uploads\/2016\/12\/Lead-Art-1.jpg","jetpack_shortlink":"https:\/\/wp.me\/p42YSK-8Sm","jetpack_sharing_enabled":true,"amp_enabled":true,"_links":{"self":[{"href":"https:\/\/www.racingjunk.com\/news\/wp-json\/wp\/v2\/posts\/34122","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.racingjunk.com\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.racingjunk.com\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.racingjunk.com\/news\/wp-json\/wp\/v2\/users\/28"}],"replies":[{"embeddable":true,"href":"https:\/\/www.racingjunk.com\/news\/wp-json\/wp\/v2\/comments?post=34122"}],"version-history":[{"count":1,"href":"https:\/\/www.racingjunk.com\/news\/wp-json\/wp\/v2\/posts\/34122\/revisions"}],"predecessor-version":[{"id":34136,"href":"https:\/\/www.racingjunk.com\/news\/wp-json\/wp\/v2\/posts\/34122\/revisions\/34136"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.racingjunk.com\/news\/wp-json\/wp\/v2\/media\/34129"}],"wp:attachment":[{"href":"https:\/\/www.racingjunk.com\/news\/wp-json\/wp\/v2\/media?parent=34122"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.racingjunk.com\/news\/wp-json\/wp\/v2\/categories?post=34122"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.racingjunk.com\/news\/wp-json\/wp\/v2\/tags?post=34122"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
