Rather than turn it off completely, why not tailor it in the tune for a margin of safety?
But anyways, back to the topic. Deleting the 1336 doesnt hinder performance. Furthermore, turning off the code, that is "no error reported" doesnt keep the system from detecting misfires. So, as for your first comment about keeping your car in "proper working order", by deleting the code, you arent doing anything thats keeping your car from being in "proper working order".
The misfire detection is only inhibited above 1000 rpm only when the dtc is set.
So, if its not set, you still have misfire detection capability.

And, sure, a Vetronix/TechII/MasterTech is nice to have... if you have a means to afford one.

When someone posts something like you'd be just as good stickin your hand up a chickens ***, and then is wrong on top of that, I'm gonna call em out. ESP, when one of the people that person is referring to is ME.

wow. this thread is getting confusing. as for an update i did drive the car yesterday and today and the car drives fine. i am going to get it to a gm dealer and get them to hook it up to a tech II once i get the car all buttoned up though. oh and someone earlier asked what year the pcm is. its a 2002 camaro pcm.

I have never successfully performed a CKP re-learn using aftermarket tuning software. I have tried it on several different vehicles using my laptop to no avale. But every one that would not re-learn with the laptop did re-learn when I used the Tech2. Without the aid of error messages in "insert tuning software name here" to tell you what parameters aren't met(if any) you are pissing in the wind. I have a hybrid vehicle and it doesn't matter what year you tell the Tech2 the vehicle is(as long as it's a gen3) because all gen3 v8's use the same CKP relearn procedure/parameters.
You do need to have the wire that goes from the brake light switch to the PCM connected in order to do the crank re-learn.(purple wire if I remember correctly)

No replacement for OE tools/software.

Edit: correct pin location. Wrong about it grounding.

Ford is the same with their CKP/CMP signal's.
Which is why I was leaning toward's checking the sensor's and wiring.
The CKP does a learn of all the variance's in the reluctor wheel and all it's sensitivities as it wears down. The crank relearn is done so the PCM will know the relation of the two for misfire detection like Ed said.
I would post that info up but it's ford specific and wouldn't do you guy's any good.
