CalcVE insanity check... duh?

[Wolfie]

OK, I must be doing something wrong here...
I checked and rechecked my data, and this MAF cal just looks wrong.
(Comparing the logged to the factory tune)
-I think a picture should follow-

Wolfie:

MAF units have to be in g/s.

As always a log, or a good screen-shot of the selected PIDS is helpful.

I.E...its always about the units..
Good to see you back..

[Wolfie]

I didn't put up a tune or log, because I figured something very basic was wrong with the numbers... I looked and looked but kept missing the "obvious"! That was from a 300 mile log, I will see what happens on the next one.

-Thanks...
--it was a rocky couple weeks, but much better now.
---I had replaced both o2 sensors, then replaced the bosh (plx) sensor,
then developed a small over heating problem... found the fan clutch bad...
then found the radiator completely corroded and seeping from both sides...
damn chevies! I could have bought a new one with all the money in repairs!

Wolfie, post some files.

[Wolfie]

Well... OK...

Wolfie:

I am fairly certain the trouble is in the unit conversion..but you never know.

By chance, do you know what the average LTFT and/or LTFTBEN(S) were for your trip? If that data is good, I can usually infer how the MAF Calibration Table should look.

If not, next time you log..do a sanity check after a few miles. I have done the same thing..logged some miles and got something mixed up with a PID or two....

Here is the log...
It was too big, and EFILive forum wouldn't upload it...
it is here...

Wolfie:

I was mistaken..You did it right. Yes, its a long log..I had to reconfigure my Scan Tool, but I got it. Not sure..but did you actually log 27 channels?

Anyway..good news. Everything logged just fine. Your LTFTBENS are reasonably good..a little positive. Your CALC.VE TABLE looks good (I probably don't understand why your IDLE VE TABLE %'s are so high)..Probably a lot I do not understand about your OS..Why does TPS never go to zero?..Or did I just miss it..or I do not understand your vehicle platform that well?

Wolfie..it looks generally O.K. I am impressed that your CYLAIR and DYNCYLAIR values are very comparable as is..Well here is what I plotted..

[WeathermanShawn]

Your CYLAIR and DYNCYLAIR side by side..Pretty good!

Shawn, wolfie has an 06 van so it has ETC. With ETC you will never see 0% TPS except at key off, the throttle position usually sits between 6-10% (or more for modded trucks) depending on conditions (A/C, cold start, etc).

It confused me at first too, both of my trucks have ETC and when I was first learning to tune I was super confused why I could never get 0% TPS.
