With the Coyote engine, and SCT tunning software I can change the throttle opening on demand as it is a drive by wire system. There is a table in the software where you can specify throttle angle based on rpm. Of-course this table is not enabled by default, so you need to set WOP=WOT Start to 1020, and WOP=WOT Stop to 1020 to enable the table. Took a couple of dyno runs (12 in total) to get the HP curve how I want it, finding the % opening of throttle to get to 325hp. Final result is great! I get all the torque up until 4800rpm, then start clamping down the HP to stay level at 325hp.<\/p>\n<p><img decoding=\"async\" src=\"http:\/\/www.johngeorgeracing.com\/gallery\/var\/resizes\/ffr4706build\/2016-dyno-tune\/IMG_4769-01.JPG?m=1459037657\" alt=\"IMG_4769.JPG\" \/><\/p>\n<p>Video of one of the runs<\/p>\n<p><iframe loading=\"lazy\" title=\"2016 March Dyno run\" width=\"474\" height=\"267\" src=\"https:\/\/www.youtube.com\/embed\/8qdIiaZVPCc?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p>Dyno chart before (full power 350hp) and after (limited to be under 325hp)<\/p>\n<p><img decoding=\"async\" src=\"http:\/\/www.johngeorgeracing.com\/gallery\/var\/resizes\/ffr4706build\/2016-dyno-tune\/2016dyno_before_after.JPG?m=1459442229\" alt=\"2016dyno before after\" \/><\/p>\n<p>And final 3 run required for ST2 class<\/p>\n<p><img decoding=\"async\" src=\"http:\/\/www.johngeorgeracing.com\/gallery\/var\/resizes\/ffr4706build\/2016-dyno-tune\/2016dyno_323hp.JPG?m=1459442229\" alt=\"2016dyno 323hp\" \/><\/p>\n<p>&nbsp;<\/p>\n<p>Pat McMahon&#8217;s car needed his carb adjusted by changing jets and restrictors, manual old school stuff.<\/p>\n<p><img decoding=\"async\" src=\"http:\/\/www.johngeorgeracing.com\/gallery\/var\/resizes\/ffr4706build\/2016-dyno-tune\/IMG_4778.JPG?m=1459037826\" alt=\"IMG_4778.JPG\" \/><\/p>\n<p>Pat changing stuff<\/p>\n<p><img decoding=\"async\" src=\"http:\/\/www.johngeorgeracing.com\/gallery\/var\/resizes\/ffr4706build\/2016-dyno-tune\/IMG_4777.JPG?m=1459037804\" alt=\"IMG_4777.JPG\" \/><\/p>\n<p>&nbsp;<\/p>\n<p>More pics here:\u00a0<a href=\"http:\/\/www.johngeorgeracing.com\/gallery\/index.php?\/category\/81\">http:\/\/www.johngeorgeracing.com\/gallery\/index.php?\/category\/81<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Pat McMahon and I visited the dyno to get all our paperwork ready for NASA ST2 racing!<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-833","post","type-post","status-publish","format-standard","hentry","category-ffr48"],"_links":{"self":[{"href":"https:\/\/www.johngeorgeracing.com\/wordpress\/wp-json\/wp\/v2\/posts\/833","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.johngeorgeracing.com\/wordpress\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.johngeorgeracing.com\/wordpress\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.johngeorgeracing.com\/wordpress\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.johngeorgeracing.com\/wordpress\/wp-json\/wp\/v2\/comments?post=833"}],"version-history":[{"count":5,"href":"https:\/\/www.johngeorgeracing.com\/wordpress\/wp-json\/wp\/v2\/posts\/833\/revisions"}],"predecessor-version":[{"id":1120,"href":"https:\/\/www.johngeorgeracing.com\/wordpress\/wp-json\/wp\/v2\/posts\/833\/revisions\/1120"}],"wp:attachment":[{"href":"https:\/\/www.johngeorgeracing.com\/wordpress\/wp-json\/wp\/v2\/media?parent=833"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.johngeorgeracing.com\/wordpress\/wp-json\/wp\/v2\/categories?post=833"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.johngeorgeracing.com\/wordpress\/wp-json\/wp\/v2\/tags?post=833"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
