02 Silverado Tune Help

[ippielb]

2002 silverado with a 5.3l engine, flex lite electric fan, cold air intake, throttle body spacers, iridium tip plugs, long tube headers, cats removed, 35" tires, 4.56 gears.

I keep burning front 02 sensors, can't seem to stop it.

Exhaust smells rich, and you can mainly always see the humidity from the exhaust like it's cold out.

truck feels gutless in mid range.

Here's my tune, rip it apart, the more you criticize it the better.
02 Silverado Sept 1.ctz

Are you sure it isn't burning coolant?

100% sure it's not coolant. Smells like fuel, doesn't smell sweet, exhaust is dry. It running rich.

Plus it has been doing this for a LONG time, and haven't had the coolant drop at all. Not just a recent thing, i bought a new duramax and have kind of neglected this truck. Just getting back to finish the job.

Would help if you posted up a log. Also, that is not a valid tune file - not sure what you posted...

It's a ctz file for putting onto the controller so I can put the tune into my truck without having to use the laptop.

What would you like me to log I will go make one right now.

[BLK02WS6]

Default metric pids would be good. Can ctz files be converted back to .tun files to view on a laptop? I never use them, so don't know...

[ippielb]

I just open up the ctz file on my tune tool, opens right up like a .tun file does. Let me know if you need the .tun file. I will get it from my truck when i get back to the farm. In tractor right now.

heres a log i dont know if its what you guys needed.

[BLK02WS6]

Here are the pids in the default metric group (ignore the x's). That is what we need to see. Mainly wanted to see LTFTs, but other things in there too...

heres the one with defaults pid

LS1B_0003.efi

Driving it right now seems like it had more balls, maybe it finished it's learn process after the new intake manifold and knock sensors. but still has that dead spot mid range and doesn't like to accelerate unless it has more rpm. Needs a little help on idle. Idles a little low and has the shakes.

Also one other thing, i have the flexalite dual electric fans, it has the variable speed controller on it, i see on my EFI live there is some spots where you can tune in an electric fan like on the new silverado's. Just curious what wiring would need to be changed, is there a kit? I have burned two controllers from flexalite for no apparent reason. I'm ready to keep them on the shelf and use the ECU to determine when the fans come on.
