Description: I was going to call it, "Water Methanol Injection EFI tuning with Speed Density at the 26th Annual DSM EVO GT-R Shootout", but it's too long. Don't worry... I only talk for the first half of this. I even shut up for a whole minute in at least 4 different places. I'm getting better. Wink wink. I want to rant and rave and promote the living daylights out of the 26th annual DSM EVO GTR shootout, but the reality of it is I brought a car, 3 cameras, 2 laptops, a truck full of tools, a campsite and spent time poring over logs while hanging out with friends and fans in person. It was nice to be able to produce content while simultaneously vacationing. I can't think of a better place I'd ever get a chance to do that? My help were volunteers and it was everything we could do to ensure the meat of this material got captured and still soak in everything else & have a good time. There were 4 people from 4 states in one state and one person traveling through 3 states who were working on my tune during the shootout. If that sounds complicated, it was, but a blast was still had by all. If I didn't have those volunteers helping out, there's no way I would even have half the footage that I do. Thank you Chad! You're always welcome on my pit crew! Tom Tharpe took a time out from all the live-streaming and all the hoards of screaming fans to interrupt me in the pits of my tuning hell. He was driving a tiny powerful 5-valve turbo 3 cylinder car that he drove to the shootout. He let me drive the Dangan ZZ and his whole journey in it is documented. I got to make a cameo driving it. I needed that break! It is well documented in both my logs and my timeslips–that was the moment the Hyundai's luck began to change. Thank you Tom! You got to make a shootout video about something fun! Lesson learned for me! Watch the whole video here: youtube.com/watch?v=lqAmPcz2HUI The fans, the food, the festivities, the fireworks, the fun, it's all amazing. It's sensory overload! I can't wear a body cam, someone would be in jail. We all worked hard to get 6 runs, 6 logs and include the shootout into this topic. The animations were exhausting, but this is an inside look at what my tuning process took from point A to point B after installing water methanol injection. Explained. Of course completing this topic required additional efforts beyond the shootout, and all of that footage and data is included. The material is pretty thick. Especially if you are unfamiliar with ECMlink, but I do my best to explain it all. With examples. 9 runs of cause & effect. Some of them are pretty bad, but I make up for it. If you use Speed Density to tune some other boosted thing with water methanol injection, the principles here are all the same because your fuel is still calculated by pressure and RPMs, so you have a VE table similar to this on whatever it is you have. This covers in EXTREME detail how I adapted my ECU to work together–yet independently from the water methanol kit because of its failsafe and some creative wiring. If you want to know more about water methanol injection that made this possible, please watch my installation video and read the description. If you'd rather read this description, well okay then... keep going... Water/Methanol is a fuel charge that becomes part of your AFR's. It makes you rich. You have to lean out your gasoline mixture when you use a water methanol kit for two reasons. 1) because water vapor displaces some of the air, making your normal tune slightly rich, AND 2) methanol is fuel, making you slightly richer-er. The non-combustible nature of water slows the burn as it converts to steam, raising your final compression and your octane rating. Intake temperatures are spectacular so the air you DO ingest is very dense. And cold. If you can lean out your fuel mixture correctly, just on the verge of knocking... there is a lot of power to be found. You'll find that knock threshold has been moved. You'll find you can get away with just a little bit more. But If you don't take any fuel out, there is literally no benefit to installing water methanol injection. It will actually slow you down. YES! I made a lot of mistakes along the way. Sometimes that's how you find problems. I got help. Plus I'm going to show you my mistakes, examine other approaches and ultimately demonstrate what works best. I understand the OpenLoopMaxOctane table a whole lot better today. That's why I waited until now to explain it. No seriously... there were multiple reasons why it took this long to comb through 987.7 GB of footage to only use 771.67 GB of it to bring you a video that's less than an hour. But by the middle of the video you're watching results happen from getting it right. I didn't break records at the shootout other than a faster pass than I ran at last year's shootout... but I did break some all-time records and they're here in this video, too!
