2004 5.3 S10/Silvarado Project

[blindawg]

2000 S10 with a 2004 5.3 motor swap* and 4L60E trans.
*when I did the swap I took every single wire, along with the gauge cluster and steering column out of the S10 and replaced it with every wire, steering column, and gauge cluster out of a 2004 Silvarado
That being said, I have a 2004 1500 Silvarado.
Motor mods-LS1 cam with beehive springs, and an LS6 intake/injectors.

I want to start with a stock tune, and tune it from there. So I downloaded one off of Tune Depot and went through and changed everything to be the way I think I want it.
I flashed it into the truck and it was super lean, and the rev sounded like it was under a little bit of load while in park.
Here is the tune I put on:
13233
Script file of what I changed:
13234
Can anyone see anything standing out that would be wrong with it?

Thanks,
Branden

Hey Branden - I can't look at tunes here at work - I'll take a look over it tonight...

[blindawg]

It is much appreciated.

Thanks,
Branden

Branden,
I'm thinking it is the injector tables... I know you changed the injector flow rate to match a stock LS6, but that has to be the problem. One thing I see is that you didn't use the injector pulsewidth voltage adjustment tables from the LS6 - that might have something to do with it... or they may not be the LS6 injectors you think they are...

[blindawg]

Good observation. :thumb_yello:
I copied everything from the injectors tab from the Z06 and put it in my tune. I don't know why I didn't do it in the first place.
At first it was lean, but not as bad, so i shut it off and started it again and all was fine. I took it on a drive and even got on it a little bit. Everything happened as it should.
I appreciate the help good sir! This is just the start so I'll probably be thanking you again sometime here soon.

Thanks again,
Branden

Hey Branden - Glad it helped! If you need anything else, post up and we will try and help!

Wow everything is working so much better now that i got that figured out. :thumb_yello:

I did the CalcVET tuning and I'll post up the graphs for a second look from you guys.

Does it look right?

Thanks Fellas,

Well I've noticed that the WB is stuck at 14.7 to 14.8 all the time. Even at WOT. Is my sensor bad or is this expected?

Thanks,
Branden

I would think something is wrong with it. What do you have yourB3618 set for?

[slows10]

I see you have B3616 set at 90% Should be lower. Also B3608 is at 2 seconds.Why the delay? Also B3618 is rich enough, maybe to rich. So yes check your wideband.

Thanks,
BrandenThis is bad.

hi Branden,

Like slows10 said, do this:
- set B3618 all cells suitably rich for boost (EQR 1.25 = AFR 11.7, or to whatever value boost-experienced people tell you);
- set B3616 to trigger easier (e.g. 50% TP under 3000 rpm, 35% TP above 3000 rpm);
- set B3608 and B3609 to zero.

edit: see corrections

[joecar]

Remind us again which wideband you're using...?

I reckon you gave me a couple wrong table numbers here, but I got the picture. lol.

I adjusted them and will see what happens. I will also check the sensor. AEM UEGO Wideband

Thanks to the both of you for the help,
Branden

My apologies :doh:

I corrected the table id's in post #12, they now read as follows:

Haha. Thanks for the corrections.
The WB sensor and gauge was fine, But the last time I pulled the dash out I somehow pulled the brown wire out of the plug for the gauge and without it in, it would only display stoich for some reason, so I pushed it back in and all is well again.

I put the T56 6 Speed in over the past week and now I'm at the point I need to tell the PCM that it no longer has an auto behind the motor. Can you guys help me out on what to change?

Thanks,
Branden

So you're running a Silverado PCM OS then? Flash a manual Silverado tune in and go from there.

[Doc]

Branden,
I can't "see" your tune right now but what you need to do is perform a segment swap. Specifically, the trans and trans diag segments. First you will need to identify which OS you are using. Second step, head over to Tune Depot and look for a manual vehicle with the same operating system-most likely a vette. Using the compare feature in the tuning tool overlay the corresponding file. It will only allow an exact OS match. Once you have it loaded goto the edit tab and you will find the "Copy segment" options. You can only do one at a time, do the trans seg first then the tranny diag next.
