Whats going on with my tune ?

LT1 with Torqhead gen 3 ecu .

Need to post the tune for anyone to be able to help.

Looks like your narrow band and wideband oxygen sensors aren't agreeing.

attached tune ,Thanks

If the trims are correct, it's very lean and you are making the computer compensate for that.

You provided very little information here.

LT1 with a torquehead doesn't really help us here as that's really basic.

What's the complete specs. Give us things like exhaust setup, what are the fuel injectors you are running, what is your fuel pressure? Does the fuel pressure match what the injector flow rate table is setup for?

Are you positive you have zero vacuum leaks and exhaust leaks pre-o2 sensor??

355 LT1 12to1 compression trickflow 21* degree heads 205 160 valves ,ported stock intake 58mm throttle body, 235/243 579/597 108+4 cam , 44lbs accel injectors, 1 3/4 long tube headers x pipe axle dump, 43lbs fuel pressure , zero exhaust leaks , intake gasket was just changed to be sure no leaks , zero vacuum leaks , I'm stumped

Disable the fuel trims and closed loop while logging it with the scanner. See what happens to the wideband reading.

If it pegs out at +17 to +18 or more on the gauge, it needs lots of fuel.

I also have no idea if your injector data is correct as I've never run those injectors before. So I can't tell if the short pulse adder, offset vs volts and minimum injector pulse is correct for those.

Thanks I'll see what it does

I love these ole LT1s!! If I can help any let me know!!

Ben Charles your pm box is full , But this weekend I'm gonna dig into my fuel pressure soon as I get the currie 9inch back under the car (I have an adjustable holley regulator and I've read bad things) I set the fuel pressure to stock which was working fine , I have the factory regulator so I'm just gonna throw it in and see if it helps

Just cleared out some space Brother

I dug into my issue a lot more , found issues with my fuel pressure regulator , but that wasn't the main issue . The mass air flow frequency table was off , I raised each cell like 1 point at a time til the o2 sensors and wide band to started correlating , there's more fine tuning to do but its way better. Thanks
