Id go ahead and get a Wideband on the way.. Know what its actually doin and adjust from there..
If it were me. i would go Speed density and dial that in. Then start on the MAF calibration. Then work on your timing and double check the AFR every log.

After 1 run then a copy and paste and write then run 2 and a copy and paste and write, I got the 1st picture, I then changed my Main VE Secondary table to reflect the same as the Primary and drove about a mile on a back road and got the last picture. Any help?

After changing the Secondary table my low RPM did WAY better than what it was doing. It wasn't surging or wanting to shut off like it had been.

Every time you change the primary ve table you need to also change the secondary table because when you disable the maf your computer uses the secondary table. So the ve readings you are getting are from the secondary table.

Ok, I did the primary and then secondary table but i run my STFT and still get numbers all over the place, im ready to !!!

calm down brother!!! haha do you have aftermarket injectors? if no, then your problem is you need to drive at least 30 minutes per session to get accurate and large amounts of STFT data, also on the histogram make sure on the top right that the letter 'A' is selected as it will give you average data. copy the points and multiply by %-half and let the truck cool down because IAT affect your air density so let it cool and try to get the same iat readings throughout the logging.

Yes I do have stock inj, I will try the "A" and also let it sit, I have noticed my IATs are some times in the "red" when I start but after you drive a bit they will fall to a little above outside temp , can I drive until it cools then hit the relearn and start the log? Or is it better to just let it sit?

Why not go ahead and get a wideband?

I looked into it monday but I have hp standard, I wouldnt mind a Gauge or hooking up through the ac wires but I haven't really read that much about it yet. Im so busy right now, their aint enough hours in the day

That should be fine. Just make sure you interpret the data right

2Slow_00

I looked at the computer and I have had the "A" selected ( guess it comes like that ), haven't had a chance to do another run but I will after work. Until then I am still reading on hp's website and here tryng to get a handel on the situation.

Any tips to help programing go easier? besides a wideband ( I know I need one)
