remember one NBO2 is flatlined because the WBO2 is installed there

hey joecar, I just changed that post to include 3 different logfiles which might have more useful PIDS

THANK YOU for looking!

Above is a tune and short log files. joecar or anyone, can you tell me where the KR is coming from and how to fix it?

You the man! Will do. I'll keep you posted on the results when I get around to revisiting the logs. Busy completing a complete teardown/rebuild of a motorcycle in my free time at the moment. ...

Calc.vet only uses the NB's to correct MAF, right? So doing calc.vet with one NB missing would still generate correct VE values, just no MAF table correction, so do I just need to correct the MAF...

So basically where I am at is this: The whole time I was tuning the truck, using calc.vet, there was one narrowband (on bank 1 I think) and there was the wideband where the other NB should be. I...

Hmm...statesman,

The red line was the last pass. Is that still too lean? What should my AFR's be looking like? I know they need to be richer, but should they flat across the power band or should...

BTW, here was the results from the dyno. Again, it's a 2002 5.3L, Texas Speed 220R 220/220 .581 lift 112LSA camshaft, American Racing stainless longtube headers with high-flow cats, and 3in dual...

I just wanted to follow up with you guys

So as it turns out, the issue with the MAF corrections coming out as 0.000'ed (and also the LTFT's being 0.0'ed) was that there was only one front...

Joecar et. al.,

Thanks for the tips. Sorry I didn't get back sooner, I left the charger to my Windows laptop in my buddy's truck on Saturday at the dyno shop, so I can't post the logs or tune...

Well, i'm getting close to the final hour....Will be on the dyno tomorrow from 11am to 3-4pm. Odd circumstances, but it's a pretty cool opportunity to get total access to a dyno for 4-5 hours free...

LastCall, what would I need to do to verify that my selben is getting correction?

ScarabEpic22,

Yeah I was always a bit confused at how values derived from instrument measurement could work out to be exactly 100.00% correct on the first time. I kind of poked around to see...

Yeah Comp 918's i think or whatever they were supposed to be. It was a Texas speed deal with chomoly rods and springs. I am glad you concur that 295hp/282tq is soggy at best and total BS at worst. ...

Cool. Thanks again joecar, all excellent points you make, and all are well received / make good sense to me.

Excuse my ignorance, but I wanted to double check when you mention "2002 F-body H.O....

Joecar, to address your points:

Yes, sorry, typo, I meant calc.vet. I've done calc.vet several times over. MAF correction multipliers were always exactly 1.0 even on the first try.

The...

Additionally here is the dyno graph provided by the tuner/dyno shop guy, which supposedly shows what the truck did when he started (with the tune file I did---see above post), and what the truck did...

First, big thanks to you, joecar, for taking the time to synthesize all that great info into this thread.

I wanted to post up some more info, and the tune files, so I can get into concise and...

Hello all from Seattle WA!

I posted here many years ago but lost my login info, so I created a new profile. Please forgive the long post, and feel free to chime in anywhere--i would genuinely...
