So after reading FFDP link I figured out what I did wrong.
I didn't take out the maf in the scanner I was not aware that I could take out maf in table prime in the scanner so that was part of the problem.

Now iv decided to try FFDP site and try that seams a little more clear.
It says their only to set dtcs po103 to no mill light and I set all of 3 of them to 0 mil on first error with the box's still checked off.

Then I noticed under ol & cl long term fuel trims that I dont have a box to disable the the ltft so I just kept going is this normal or ok????.
Those are the only things I did different or didn't have on the guide.
I have the 2.24 version

Loaded it and it stays running but I didn't have a chance to see if it logs.

In order to disable the LTFT
Set the enable temp to 280 or whatever temp you will not hit
Also put the min MAP vs baro values at the maximum value
Open your scanner,reset fuel trims using the bi-directional controls
And your LTFT will then be disabled and reset!!
If you need help,shoot me a pm

Question for you. Are you using the built in AFR ERROR histogram to see how much your fueling is off, and then doing a copy/paste special into the VE table?

If so, in your prebuilt AFR error histo, does is have a filter string to remove anything under stoich, like this?

[SENS.121]

No I was not at the time but have added it into the hist.
I was copy and paste special off the ve ltft which did not work kept adding fuel.
Should I have been copy and paste special of the afr error?

I went into the setting in hist under afr error and under sens I do see a sens.121

i'm sorry, for some reason I cannot type [SENS.121] "less than sign" 14.6

the forum keeps erasing that from my post.

Do you have the filter that shows the "less than sign" and stoich? just wondering if that data needs to be filtered out before logging.

Thanks

I'm not sure I follow you 100%
I did find sens .121 which is afr command lo res I think
It's not at -14.6 its at just 14.6.
I did log it and looked at the hist and its showing neggiteve numbers now.
