Basic tune for 2011 Sierra 5.3 w/o wide band

[BADFNZ]

A family member is going to let me use his HPT for the weekend so I can tweak my Sierra and Camaro. I'm new to the AFM 5.3, so I'm just looking for what basic tuning I can do without the aid of a wide band. From looking through old threads, it seems most people just scale down TM, some disable AFM, and do some minor tweaking to the MAF tables. Is there anything else I should do?

It's been years since I've used HPT on my Camaro, so I'm going to have to relearn a lot of this stuff. I don't want to go overboard, but just want better drivabilty, more power under the curve, and possible better MPG.

Any one have any input or have a HPT file that I can use for this?

Airflow, electonic throttle, opening rate limits, set all to 100%

TM, general, ETC limits, leave the 0 row alone, set all others to 100%

Max all your allowed torque tables under TM

Increase your dwell to 5.5ms in all areas where it is less than that, and change the multipliers for the dwell all to 1.0

Triple the Knock delay recovery

High octain timing table set to 25 degrees in the WOT areas, smooth others, remove negative timing down low. Start in lower left of timing table with 11 degrees, blend it and smooth.

For transmission, increase shift speed to .150 in lower to .125 in the upper

Dont get crazy with the pressures just to get it to shift hard, you dont want that, you want fast not hard. Dont change the rev limiter, the stock trucks wheeze out at 5800 anyways. If you change the WOT shift speed, dont forget to change it in the part throttle shift speed 100% area too, and remember to match your rpm AND MPH, as it needs to meet both to shift, so log first. Dont remove more than 50% TM without servos, and sonnax shift kit stage 2, or transgo kit or your tranny will likely fair sooner than later.

Pardon my noobness, whats is the benefit of this?

Ah Christ! What the fuck! I swear I'm about to quit the board with shit like what's listed above! When I joined did I bring all the hacks with me??!!



Sorry OP that is not directed towards you.

I have no idea what you're talking about, so do you want to explain?

He probably doesnt like the knock recovery increase. Some people do it, others dont. He bitches and moans worse than a woman if it isnt something he doesnt do.

Hell a year ago, he couldnt even tune a tranny.

I have been tuning 18 years, since I first bought my GN. He should just learn to keep his mouth shut and not post negative comments. Notice how he didnt offer to help you.

Just know that when you come here, you will run accross many people, who have many differant ways of doing things. Take a little bit from everyone, and make your own way. Half the fun of tuning is learning along the way. The stock knock recovery takes forever to give the timing back. The table that I told you to modify will only give it back IF THERE IS NO NEW knock retard, which is fine. I have seen computers pull timing for knock and not give it back till almost the end of the 1/4 mile, so I adjust mine. If he has something positive to say, listen to him. But ignore all the whiney complainers who that is all they do and dont help.

^ don't make me bring it down on you about your methods.

You're a fool. I'd be inclined to help, but since your a seasoned know-it-all tuner, you can just keep doin' to thang. Know what I'm saying?

Good day.

This thread caught my eye because my Dad has a 2011 Silverado with a 5.3.
Op, don't spend to much time searching for servos and a shift kit.

That doesn't make you right by any means, as evidenced by your other posts.

Dumb people man. Just dumb people.

Ok well, I have a few different write-ups concerning trucks and truck performance.

They're balls rich from the factory. You're going to find most of your performance concerning AFR. Setting your PE to 1.180 across the board, and then setting enrichment rate to 1 is going to lend you a decent amount of power across the board.

Still, bottom end is pretty soggy. So, we've got two places to look. Torque converter stall fuel cutoff, and timing.

Max out the stall fuel cutoff, trans torque tables, etc.

Timing you can then start at about 12 degrees WOT at 1000 rpm, ten increase to the max FACTORY value.

More can be done, but that's strictly for performance gains.

6sp trans correct? Trans tuning alone helps a good bit. If you post your stock tune when you get hpt ill be glad to help any way I can.

[BADFNZ]

Here's the stock tune if anyone is interested. Only thing I've done is changed the speedo cal for bigger tires.

[BADFNZ]

Here's my updated tune. All I've done is a little PE and IAT spark tweaking. I'd like to finish with the engine related stuff before I move on to the trans. What do you guys recommend for the low and high octane spark tables?

See post 11

I saw your post, but then saw you post a screen shot in another thread of a high/low octane table you recommended and they were different. I was seeing if there was a consensus within the masses.

[IDRIVEAG8GT]

Hmmmm ok give me a sec, and I'll post a good one up.

[IDRIVEAG8GT]

Check these out:

In the midst of that, I also want you to fully disable Burst Knock Retard.

With this timing table, I recommend that you only run 91 or better.

I'll help you with torque management when you're ready.

[BADFNZ]

I've made most of the changes you suggested and kind of tweaked them a bit myself. I don't want to be handcuffed to 91+ octane, so I toned the timing down a bit from your numbers.

The only thing I didn't tweak was the Torque Converter Stall Fuel Cutoff because I couldn't find that. What exactly does this do?

I'm also ready for TM changes if you have any suggestions.

Attached is my latest file. Thanks for the help.

It is nice to see members helping out people
