I did the CalcVE tutorial with the NB's and all the numbers look really good, MAF is good, and LTFT's are good too. Now I want to use the WB to finish off PE, WOT and whatever else, where do I go from there since I already did the CalcVE tuning? Thanks. I've got a good grasp on how to do the MAF and VE tables but now that i'm ready to do my PE and WOT i'm just not sure where to go and what table to set without messing up the other part of the tune.

Your on the right track..http://forum.efilive.com/showthread.php?15236-A-New-Twist-on-CALC.-VE-Table..Computing-the-Entire-VE-Table.

It does not get any easier than this method..:rolleyes:.

Ok I added the PID for calc.ben1. Now to PE mode how do I set the tables and what tables. For WOT I want 12.7 afr but I want to richen up bottom too, for example 3000rpm @ 65kpa I want 13.1. I think i'm confusing myself looking at the CalcVE tutorial and AutoVE tutorial. I'm trying to set the tune with altered tables but keep confusing myself. Like what to shut off and what to leave on.
I'm guessing i'd basically use the whole CalcVE tutorial again but utilize my wideband instead of the NB since the VE and MAF are in check using the WB. But to do the PE what tables do I set, to what. Thanks sorry if this sounds like a newb question i'm just trying to figure out all the different methods here.

Tim, I assume you are still using the MAF. So utilize Table B3618 to set all your PE Mode fueling. I strongly urge you to set all your fueling parameters to EQ. In your Tune Tool, undre Edit..Properties..Display in EQ. You can still read your wideband in AFR, but setting it to EQ will make your life a lot easier. Then your BEN Pids will all work etc..

Personally I set PE Mode all to one AFR/EQ. For starters I just use 1.16. But that is totally up to you. Then I set B3616 to either stock or stock -10%. Again, preference.

If you follow this method you do not have to fool with B3605 or any other Table.

Yeah when i'm done tuning it's gonna be just like stock. Have the NB's and MAF. But unless he gets it done today I have to pull one NB out to put my WB in. I

Gotcha.

Thats O.K. since you won't need your NB for PE Mode/WOT Tuning. You'll basically just be using the WB BENS to tune your MAF in the higher ranges. The VE Calculation is just an added bonus..

If you use b3618 to set your PE, that just goes by RPM, I would think you'd only need richer afr during high load. How can you change the afr with regard to rpm and map, that would be b3605 right?

Would this accompish anything or be going backwards. Since my CL-MAF is in order. If I disable the MAF, disable LTFT, and set to OLSD esentially, set my PE to the RPMs and MAP that I want. And use my WB calc.BEN1 to calc the VE table. This should be pretty straight forward since all my trims and MAF are good from the CalcVE tutorial I did. Oh wait in higher rpm's it only uses MAF so this won't work right?

Sounds like you are going to get really confused trying to mix and match AUTOVE and CALC. VE Table.

B3605 is a good match for open-loop. B3618 is a perfect match for MAF-enabled cars.

I can't really advise you to mix and match..

Ok last question and i'll stop sounding thick lol. Can you leave MAF enabled, and shut off LTFT, STFT since i'll be using a WB? And basically shutting off LTFT, STFT will give you an exact AFR or what your tables are commanding since there would be no trim corrections correct?

Tim, you do not need to Disable LTFT's or STFT's when using a WB. When you hit PE Mode they automatically 'turn off' (they lock).

Some Tuners will Disable LTFT's as the PCM will carry +LTFT's into PE Mode. Thats why we try to get the LTFT's as close to zero as possible. That avoids that problem.

Best thing is to log all of the same parameters as CALC.VE Table. It will be easy to tell if your fueling is off or its hopefully perfect!
