cam interrupt wont clear DTC

[slow6]

1) Upon my rebuild... I broke the plastic on my cam interrupt.
So I made my own and it set off a DTC
Recently I put in a real, new cam interrupt and the dtc is still there.
I've tried doing case learns (about 6, before and after the new one)
but DTC is still there

2) What is the minimum rpm you have to rev to during a case learn?

3) Whats an indication that your WB has gone bad? I'm sure mines bad now.

4) Max LTFT is +35 to -35 right?
Reason I ask is because sometimes while driving I wont be in a current LTFT cell at all. So I am without data and dont know if I'm rich or lean

6) Why do rpms dip below the IDLE Target range of 720 rpms or whatever? Is it because the trims Cant find a good AFR? Thats what I'm thinking.
Throttle response is Horrible...definately a lag there (bad AFR?)

Thanks

4) Why would an engine "POP" on cold start? Dont know if its starter striking driveplate or what. I will have to get videos

5) Max LTFT is +35 to -35 right?
Reason I ask is because sometimes while driving I wont be in a current LTFT cell. So I am without data and at a loss

Type of car/engine?

[slow6]

02 camaro v6 3.8L 3800 Series II

[slow6]

how can I have such KR at 500 rpms and -23.4 LTFTs? lol
917 and 892 o2s (I know its slightly lean)

Just click on the image a few times to zoom in

[Russ K]

Your way too rich, not lean.

Russ Kemp

[slow6]

it would seem that way
but if I lean the VE table out by -1 or -2 points on the VE table
it will get KR in that area

o2s show lean most of the time (under 900 mVs)

I cant get LTFTs into the -10s range
Cant figure out whats wrong with it lol


Thanks for the feedback / response!!
feel free to respond again!!

[Russ K]

Just leave the VE table stock, and tune with the Maf table.

You said I was too rich
Plz check out these LTFTs and KR tables
Why am I getting KR if I'm too rich?
DFCO IS OFF
thanks

[slow6]

Here is another deal:
it always seems that I get KR when (LTFTs & STFTs are -negative = rich) . also (low rpm). also (o2s at a high mV = rich) ...low timing

It just seems like I shouldnt be having KR unless its false shift KR.

Plug your maf back in. Your spark timing & knock histograms won't work with the maf unplugged.
The knock is most likely false, but you really need to get your afr right first.

What is all this data I have in my histograms (1 & 2) Each time I log then?
Is that a v8 thing? It Seems to be working... BUT

If you were to tell me "it looks like its working but actually will not work right because it has limited data input" then I would totally believe you
This is the case?
thanks,

Will plug it back up
