I havent compared it to a stock file, you could call out your tooner, or go down the road of learning, you could also try a few from this forum. If...

Go to Walmart and get a PS5 controller cord. Really well made and 6ft length helps when the laptop is in the passenger seat.

Yeah. And if I change OS's to one that supports flex then my VIN will be invalid for model year.

Ouch. Most people p59 swap that if they are not staying stock. In will check the pcm hacking forum later.

Got a place to stick it and leave it or are you going to put it in place of a narrowband?

No wideband yet waiting on the prolink since I don't have a can bus. Should be here tomorrow hopefully.

Alright run it a while so we can be 100%. This'll really settle in the LTFT's, too. Wideband yet? The main change was the delta airflow table...

99 Firebird. 9381344.

Sorry for the thread derail, but are you talking '99 f body or truck? I'm guessing a 411 computer, but which OS?

cleared ltfts no knock and no dtcs. Ran really good finally got some top end. So basically, taking the burst knock all the way down but don't zero it...

@jaegerWrenching here is the latest I have. Not worth much tho, in the middle of the pull the fuel pump relay burnt up and blew the seals out of...

That's alright. Use VCM Scanner>Vehicle Controls and Special Functions to clear LTFT's after loading this tune.

I was not able to get to that truck today. Do you think it's possible to flash the ecm back to factory with a Tech2 Win and then turn off the WVT to...

Try this and see if it helps. Cleaned up a few things as well.

Yeah, but was just making sure that's what was logged. You were running SD4 for a while. Let's try this guy's suggestion:...

Yeah I just compared on laptop the last tune and PC I had the base tune all the same. So what do you guys suggest? Starting anew? I feel like I...

I believe sd5 is the last one you gave me

Not yet. What tune were you running?

looks pretty clean to me. I don't have a pcv valve going to it. I'm venting to atmosphere. Should I clear those codes?

Oh hey. P0327 and P0332 codes for the knock sensors.

Still curious if anyone has a read.

Which tune? Real quick look down the throttle body and inspect for oil.

Offset/Linear are correct in the tune.

I exaggerated a bit it's more like 50 miles there 50 back, but I would bring a container with me to store some of it. Here is the new log after the...

Actually I’m not sure that saying they use pwm to control is really correct. ECM actually calculates how much fuel is needed for conditions and...

#s in post 4 should be correct for that sensor.

What does this have to do with the VCM Scanner software? Just that the log was recorded using the scanner? If so, then every tuning question should...

That might not be a "burble tune" just a half ass tune lol. MPVI standalone logging sucks, If you are stuck with that, then reduce the channels quite...
