E85 2016 Silverado Reg Cab 6spd 4x4 5.3 upgrade

[SCR71822]

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.

Got my OEM front fuel line.  Will install soon.  So far no problems.  Feels a bit more torquey.

If you program with the Hypertech are you able to use the HP tuner to see what changes was made??

I'm interested in doing this although I'm sure warranty issues could arise. Thanks for your hard work for providing the information.

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.

Very true only way they could know is the RPO codes which they never look at it. Hmmm. I may have to wait till you take your truck in for service and see if they say anything lol.

I'm trying to figure out how to make a new RPO code sticker for my glove box.

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.

Here is a company that makes reproduction labels, I just photoshopped  it to change FH0 to FHS.  Label is kind of expensive.

I wish our 2016 Suburban had the E85 pigtail.  No such luck.  I would like to convert it.

My 18 doesn't have rpo code sticker.  It has the bar code scanner box.  That shows all the codes when you scan it.

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.

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)

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.
