Just the same as the histogram you had setup to tune your MAF or VE but instead of LTFT or STFT (or whatever you were using, you replace that with the info from whatever prolink+ channel (red, blue...

do you have a tune file and a log?
no poblem. let me know how it turns out.
I'd be happy to but it wont be til tonight. im at work for another 10 hours. do you have cam specs? stall converter? is it a 07 classic or nnbs? Have you adjusted anything in the tune yet?
Everyone is going to tell you that your "base tune" is going to be a stock file and most people wont just give you a file that they have worked hard to make for their own or someone elses car. Most...
sorry for the slow response. I tried LTFT+STFT and just LTFT for tuning VE and MAF and i didnt have very good luck with it. Personally, using STFT has worked best for me on everything ive tuned. Im...
TBH i have gotten much better results using STFT to tune VE and MAF basically everywhere but WOT and PE conditions. Post a tune and a log if you have it and i can try to help. im running a P59 which...
post tune and log when you get a chance or no one will really be willing to help on this forum. im running a similar setup in a yukon LM7 but just plugging my tune into your ecm wont do you much good...
Do you happen to have any idea or guessed why that is? Id like to know if theres a certain reason why so i can keep an eye out for it.

Yeah, youre gonna get that no matter what. ive been tuning for about 8 years now and ive only asked 1 question on the forum but i felt like an idiot when i got answers lol just gotta suck it up and...
did you recalculate for the larger TB? yes a wideband is worth the money. Its the only way to tune WOT and PE.
i wish...
hmm, thats interesting, I had a similar issue before i got my MAF dialed in really well and was running Dyn Air. Are you running SD, MAF, or Dynamic Air? If your banks dont match then maybe theres a...
Id change settings to MAF only in tune settings and try to collect some idle data using STFT. Get the idle and light throttle freq corrected and then once that is done and it idles better then try...
is the cam the only thing that has been changed from factory?
What are you STFT showing? since LTFT is an average product of those, i would think that theyre pushing your LTFTs that direction from the time theres enough data to average to make a LTFT reading.
here is the procedure from HP tuners site. I hope you werent just shutting it down as soon as you get to fuel cutoff as you stated.

more than likely you have an E38 pcm. OL also uses the HEGOs but it has no power to change the fuel trims, whereas CL is an average of the OL readings and IS able to adjust fuel trims based on what...
i didn't have very good luck trying to tune both VVE and MAF at the same time. there's too many variables to filter IMO. I went OL w/ no LTFT and tuned MAF using STFT and had great luck with it. not...
Go to goat rope garage and watch his Gen 3 videos on MAF and VE tuning. that should get you to where you want to be.
I ordered mine from scoggins dickey in TX because HP was sold out and they were the cheapest place at the time. It was a goo buying experience overall.
I completely agree with this statement. When i first started to tune i asked the same question about the timing tables. after watching histograms for awhile and doing several pulls at different loads...
Setup your VCM scanner to log Volumetric efficiency, dynamic airflow, & MAF (freq) in the channel section. I tune the MAF first since its quick and then turn the MAF off and log VE. i personally like...
