  1. Sitting at 70.6% Ethanol, feels even better. That was Thornton's. Next fill-up I will try another station see if they have higher % Feels great to drive now.
  2. I had to dial the Shift Firmness down to Tow as it was too harsh at WOT. The truck is fun to drive, breaks the rear tires loose easy now, super fun to drive. I have to up the Alcohol % to 70 or higher at the next fill up.
  3. Well I am at 60% Alcohol now so I tuned It with my Hypertech Max Energy 2.0 using the following params: Premium Fuel tuning Throttle Response - Track Shift Response - Track Shift Firmness - Street I tried a couple firmness settings, and the heavy acceleration shifts were way to harsh for me so I have been dialing it back, The more aggressive shift firmness had great part throttle shifts but very clunky high rpm shifts. I pulled HPtuner dumps after each one so I can figure out a good medium.
  4. I thought I would post this this is the factory rating of the L83 5.3 on E10 and E85: Horsepower (hp / kW @ rpm): 355 / 250 @ 5600 (gas – SAE certified) 380 / 283 @ 5600 (E85 – SAE certified) Torque (lb-ft / Nm @ rpm): 383 / 519 @ 4100 (gas – SAE certified) 416 / 564 @ 4100 (E85 – SAE certified) Read more: http://gmauthority.com/blog/gm/gm-engines/l83/#ixzz5k8VxHIzf
  5. Have you tried a QR code reader on your smartphone just to see what it says yet? Dump the text, edit the FH0 to FHS then recompile the QR code https://www.the-qrcode-generator.com/ Take a screen shot of the new QR code and a picture of existing label, photoshop the new QR code on the existing label, send to the printer to have the label printed.
  6. http://www.ecsvin.com/order.php Here is a company that makes reproduction labels, I just photoshopped it to change FH0 to FHS. Label is kind of expensive.
  7. I tried to see what is involved in the changing the fuel line, and those retaining clips are a pain...so I am going to just replace all of them, it's only like 20 bucks for new clips and I don't want to waste time babying them. I also bought extremely long needle nose pliers from Harbor Freight for $10 to open up the metal retaining clip on top of the trans, I want to attempt to do it without having to unbolt the cross member and dropping the motor/trans.
  8. I'm trying to figure out how to make a new RPO code sticker for my glove box.
  9. That is why I am using OEM parts, I doubt they will know, its very subtle. I have 31000 miles on my truck now. This was a $100 option on my truck, so its not like it is not supported.
  10. Got my OEM front fuel line. Will install soon. So far no problems. Feels a bit more torquey.
  11. I have a hypertech max energy tuner I will use to program it soon after I get a full tank of e85. I will then have a good baseline tune I can play with to try and get more power.
  12. I'm happy with the conversion so I decided to order the OEM front uel line as well and install, it was only about 55 bucks. Total cost of the parts is about $130 or so, big cost was the HP tuner.
  13. I put about 6 gallons of E85 in to fill the tank. It is now showing about 30% Ethanol. It seems to have a little bit more torque and able to stay in V4 mode longer before. I can't wait to get a full tank of E85.
  14. Just took for a drive and looked for leaks, no leaks. Programed the ECM and t saw the alcohol content at 11.8% which is about right since I use E15 usually. Well I have to wait for my tank to go down so I can fill up with E85. Here is a picture of the fitting I used, I repurposed the quick connect fitting from the old line I cut.
