I prefer to use stock GM PCM&#8217;s in my projects but recently I saw Speeduino for the Arduino Mega.<\/p>\n\n\n\n<p>I have a shifter cart outside that needs some engine work so I thought &#8220;why not build a fuel injection system for it?&#8221;&#8230;<\/p>\n\n\n\n<p>Speeduino and TunerStudio installed pretty easily. The first thing I noticed was the display called for was an OLED. I didn&#8217;t happen to have one so I rewrote the display module to use a much cheaper Nokia 5110. The original display showed 4 pieces of numeric data in a 2&#215;2 grid and a bargraph at the bottom.<\/p>\n\n\n\n<p>On the 5110 I was able to fit 10 items vertically with 4 extra pixels along the top for the bargraph&#8230;.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/es.pratt.edu\/Commons\/Images\/arduino\/speeduino\/IMG_3751%282%29.JPG\" alt=\"\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/es.pratt.edu\/Commons\/Images\/arduino\/speeduino\/IMG_3753.JPG\" alt=\"\" \/><\/figure>\n\n\n\n<p><a href=\"https:\/\/es.pratt.edu\/Commons\/Images\/arduino\/speeduino\/display.ino\">Just replace display.ino with this one&#8230;<\/a><\/p>\n\n\n\n<p>First thing I wanted to try was a bench top simulation. That means I needed a 36-1 trigger wheel and something to spin it up. This is a common trigger wheel used on ford vehicles and can be found in most auto parts stores. I didn&#8217;t need the real thing for the test bench so I printed on on the 3D printer&#8230;<\/p>\n\n\n\n<p>I went to the RC parts drawer and got a small outrunner motor and matching lithium, battery, speed controller, and servo tester. A small prop adapter and I put it all together. It spins up pretty smoothly. Now I just have to mount it all to a board and attach a small opto interrupter to get the signal to the Mega.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/es.pratt.edu\/Commons\/Images\/arduino\/speeduino\/IMG_3744(2).JPG\" alt=\"\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/es.pratt.edu\/Commons\/Images\/arduino\/speeduino\/IMG_3745(2).JPG\" alt=\"\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/es.pratt.edu\/Commons\/Images\/arduino\/speeduino\/IMG_3746(2).JPG\" alt=\"\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/es.pratt.edu\/Commons\/Images\/arduino\/speeduino\/IMG_3747(2).JPG\" alt=\"\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/es.pratt.edu\/Commons\/Images\/arduino\/speeduino\/IMG_3748(2).JPG\" alt=\"\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/es.pratt.edu\/Commons\/Images\/arduino\/speeduino\/IMG_3749(2).JPG\" alt=\"\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/es.pratt.edu\/Commons\/Images\/arduino\/speeduino\/IMG_3750(2).JPG\" alt=\"\" \/><\/figure>\n\n\n\n<p><a href=\"https:\/\/es.pratt.edu\/Commons\/Images\/arduino\/speeduino\/encoder.stl\">You can download the stl file I used here<\/a><\/p>\n\n\n\n<p>That&#8217;s all for this weekend.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I had been following DYIEFI and Al Grippo and Bruce Bowling for a LONG time.
