It was\nproduced for over 14 years from 1987 through 2001, and was a relatively popular\nengine choice for class 7 and 8 on-highway applications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Both the Cummins Celect and Celect Plus Engine Control Modules (ECMs) are the types of car engine computers that were produced by Cummins for their N14 diesel engine during that time. <\/strong>Originally, the N14 engine had a purely mechanical fuel injection system, but with the rise of electronic control modules in the late 1980s, Cummins created their own ECM called the <a href=\"https:\/\/dieselecmexchange.com\/blog\/cummins\/celect-ecm\">Cummins Electronic Engine Control or \u201cCelect\u201d<\/a>. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Instead of relying on purely mechanical processes, The N14\nCelect relies on electronically controlled, camshaft driven unit injectors. In\nthe system, the camshaft provides final fuel pressure in each individual fuel\ninjector but the injectors utilize electronic solenoids that are actuated by\nthe ECM. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Although the injectors were still cam actuated, the control module controlled the metered flow of fuel to the injectors. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Then in 1997, Cummins took a further step and <a href=\"https:\/\/dieselecmexchange.com\/blog\/cummins\/celect-plus-ecm\">introduced their N14 Celect Plus<\/a>, which further fine-tuned the ECM to control many more custom parameters of the fuel system. This made the N14 diesel engine more efficient and more environmentally friendly. <\/p>\n\n\n\n<h2 class=\"sec-sub-title-2\">Difference Between Celect vs. Celect Plus ECM<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Whether you need a Cummins Celect or Cummins Celect Plus ECM\nessentially just comes down to which version of the Cummins N14 diesel engine\nyour truck has. Here is a breakdown of which ECM is right for your particular\nvehicle:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li class=\"showbullet\">1987 \u2013 1989 &#8211; Mechanical injection pump,\ncamshaft controlled mechanical unit injectors, pressure-time (PT) injection\nsystem (no ECM).<\/li><li class=\"showbullet\">1990 \u2013 1996 &#8211; <strong>Cummins Celect<\/strong> electronically controlled injected system,\nelectronically actuated unit injectors.<\/li><li class=\"showbullet\">1997 \u2013 2001 \u2013 <strong>Cummins Celect Plus<\/strong> electronically controlled injection system\n(more sophisticated ECM, diagnostic features than previous Celect system).<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">But no matter if you need the Cummins Celect or Cummins\nCelect Plus ECM, all you need to do is enter the year, make, model, and VIN\nnumber of your truck on our website, and we will do the work of programming\nyour new Celect or Celect Plus ECM to suit your particular vehicle. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Cummins N14 is one of the classic diesel engine platforms produced by the legendary engine manufacturer, Cummins Inc.
