Yeah, that does seem to be smoothing out rather well.

I'm hoping I can take care of the throttle response in spots that feels a bit soft to me without hooking up the wideband sensor again. The throttle cracker table should allow me to provide more air in the range I'm targeting, but I have to be careful that more air doesn't mean it gets too lean on me. I may have to goose the fuel via the VE table in that range as well.

I think I need to take a look at my old logs and just analyze the AFR in those cells and see what is going on. It may be too lean or too rich causing the softness and I can maybe just fiddle with that a bit. I'm thinking that, if anything, perhaps there is a temporary lean situation going on during moderate gas pedal pressure. The problem is that I don't think the VE table is the way for me to tackle this. This sort of situation is considered to be a transient effect whereas the VE table is pretty much for static events. Matter of fact, when tuning the VE table, you try to filter out any transient effects from skewing the results you are looking at.

BTW, in out chat we were discussing the size of the file being downloaded to the PCM during the flashing process. The file size I am seeing of the saved file in EFILive is roughly 175K to 178K. I'm not sure what causes the variances in file size there. But so far ALL of the files being loaded to the PCM during a calibration flash are only 96K.

So there are a couple of questions here. Does EFIlive capture EVERYTHING in the PCM when you save an image to the PC? Of the remaining 82K or so that is not uploaded during a calibration flash, are there other tables that are not being addressed by EFIlive or is that all the operating system that would be uploaded during a FULL flash?

I was told that the tuning software for the TECH II can address a whole lot more tables than the commercial tuning software products can, but at this point, I guess I have to classify that merely as hearsay.
