2000 Camaro Z28 - stock LS1 trouble

Also, without the wideband I don't have the ability to check my A/F ratio. How safe do you think it is to go into WOT with the MAF disconnected?
Anyways, if you don't plan on replacing/ cleaning your maf anytime soon then this is what I would recommend. I'm sure you've noticed the service engine soon light is on.....save a copy of your current bin and store it away. Then, scan for the codes, they should all be maf related....delete them in the editor and reflash your computer, your SES light should be gone now. Now, while scanning make sure your WOT timing is the same as it was with the maf connected, make sure your trans shifts the same as before and not super hard (even at part throttle) and check out your fuel trims to see how close to 0 they are. BTW, you should reset them since they will be different without the maf. You could go as far as running a MAFless intake setup which could potentially free up more horsepower but thats completely up to you.
Thanks so much for the help, man!

Ok, well either buy a new maf or do what you need to run SD.
I didn't say clear the trouble codes, I said go into the editor and set the code so it doesn't report a problem or show a SES light.....otherwise its just going to keep coming back after you clear it.
Your timing should be the same and fine, I just said check to be sure.
Yes, its ok to run WOT in SD mode. You should always use a wideband when tuning a/f ratio regardless in my opinion, but it should be fine where it's at, it may even run a little leaner than your stock tune and run a little stronger and smoother.
your air box is going to have almost no impact on your SD tuning.
hey now this isn't YOUTUBE, you are aware an auto will usually beat a manual, stock for stock, from a dead stop right? My automatic vette with 2.73 gears ran a 12.98@109 with an intake and a quiet catback, the car drove itself. Oh yeah, my buddy's automatic 00 camaro with an intake and a blowmaster muffler ran a 12.80@108.88.
You mention reflashing the computer, I think that will reset the LTFTs but will it cause the light to stay off?
You think the spark timing should be the same?
Also, without the wideband I don't have the ability to check my A/F ratio. How safe do you think it is to go into WOT with the MAF disconnected?
And as far as running a MAFless intake, I think I'd need a wideband to tune it, correct?
I don't need to worry about the tranny shifting, it's a stick (never understood why someone would by a 300+ stock hp car and dog it down with an auto
