JRoyPDX 2017 Silverado RCSB Z71 build thread

JRoyPDX · October 8, 2017

With help from @mike91b on some transmission calibrations, I managed a 14.4 at Portland International Raceway. Much quicker than I expected for a basically stock truck.

Bye stupid chrome piece. Had my local vinyl shop wrap it in gloss black.

Do you mine posting your tune so I can compare tune? Oh is this 6 speed. Thanks.

Yeah, 6 speed. I dont think the LT rcsb has an 8 speed option.

Here is tune file, no engine changes from stock except for afm disable.

A quick look it didn't look as crazy or aggressive as I would have guessed. I see all the disabled up torque reduction. Interested in your thoughts on the speed being changed to 120 and max of 135. Stock drive shaft and slicks at track?

I am going to load a .2 shift increase time and max out line pressure, as well as disable reduction and set the tables at 800.

Undecided on DOD. I hate the delay between v4 and v8 and on a turbo I would rather keep the manifold pressure even(I will log that with EGT on the HPTunerPro.

Are you going to get in to the fuel tables at all? There is a ton of room to improve there I mean 16.48 A/F with enrichment is insane, but also it is a guaranty it can't lean out. I am shooting for a 12. to 12 half. With no increase in tables under boost. Again the Wide band and logger will help with understanding the "why". Oh and at this point NO E85.

I will get it up on the dyno after the start tune and street testing are done, mostly to set the boost controller (4lb spring so max is 8 or less)

I moved my speed limiter up because I don't need a computer to control that for me. I can just use my brain, and my truck isn't fast enough to worry about it. Also a 2017 rcsb has a steel 1pc, no more aluminum

Mine isn't too aggressive, but it is safe and it does move out really good.

I have logged af with my wideband, stock they're in the 10.5-11:1 range under wot with sensors after the cats, so probably a good 1/2 point richer than that.

You guys make me want boost so badly.

Here are two logs. One is my best 1/4 mile pass, before I had my wb02. You can see what those shift settings are doing. The other is my commute home from work, the day I got my wideband. The WOT portion of that log starts at about 13:15 into it.

Interesting I like this last two files. I will email them forward and see what the the best in the game can do or say. Thank you, as they are helping me with mine. This is just me learning With the new platform I have done tuning in older platforms but this is way different. Thank you very much for sharing.

Maiden voyage for my other truck. First test passes got me a 12.01 @ 113mph.

Upgrade! I decided to put a little audio in the truck. Good solutions for a reg cab kinda suck.

Decided on a simple kicker sub/box combo and a kicker amp. For line oit conversion I opted for an Audio Control LC7i so that I'd be ready if and when I decide to upgrade all the speakers and add a 4 channel amp.

This post will show the build of an amp rack and a shelf for the sub box. Made from 1/4" ABS plastic.

You have to imagine it with all of the carpet and plastics back in place, heh.
