Calc.VET: correcting MAF and calculating VE (in single log)

I will look at the log and see what the selben is in the rich area and let you know.

yea it is pretty fun to drive, its running pretty good.

Thats a new one for me..:confused:. How much (over stock) have you had to adjust B5001?

I will look, dont have my laptop with me know. I did a search and I think I just need to raise the values in the predicted map low tps areas by another 10. Everything works just fine just one of the pesky rationality test the stock system runs.

***CALC.VET Tutorial Update:***

Officially the New CALC.VET Tutorial remains under 'construction' for the time being. There are still a few PIDS and perhaps 'coding' upgrades to occur in the next few months.

The Tutorial contains the most detailed instructions on constricting MAPS, etc. So, it will be kept updated periodically. Page 1 of this thread contains all the updates:http://forum.efilive.com/showthread....l=1#post135867

Thank you..

Shawn, thanks for the effort :cheers: writing a tutorial is hard work.

Look at these tables:
- C2911, C3003-4 for the rationality test limits,
- C2907-10, C5501-2 for disabling the rationality tests as last resort.

Shawn the selbens at the lowest afr in frame 6618 is .9212. That is showing a 10.13 afr. If I highlight frames 6617-6625 I get a average afr of 11.29 and selben avg of .9606. Frames 6586 to 6614 show avg selben of .987 and avg afr of 12.16. The maf hz highlighted in the tune are from 9625 to 11750. I will see what those areas do on the next log. So it is close. The adjustments made after the last log should make it even closer.

Len, perhaps we have our Scan Tools set-up at a different Frame Count..Those frames don't match up with what you gave me?:confused:.

Also, is your vehicle Electronic Cable or By-Wire?

I am trying to figure out why you are in PE Mode on deceleration, and low throttle.

I.E., in screen-shot your PE Mode factor 1, EQ 1.03?

Len, also make sure you have B0701 set to DISABLE.

Looks like from your Tune you have it set to ENABLE. Could be why you are richer than commanded. CAT PROT takes you to 1.25 EQ.

Also that may be some sort of CAT Efficiency Test. We have to figure this one out. I have never seen an EQ > 1.00 at cruise or decel..:confused:.

ok so let me get this right (redneck diesel enthusiast here)... The commanded fuel values for this obviously have to be set in EQ Ratio and not AFR. Possibly its posted but maybe i missed it, is there a conversion that can be used to see what the EQ is in comparison to AFR? Im playing with a genIII 5.3 here and this writeup is amazing, very good job.

Also, im not using a wideband, just closed loop with the factory sensors
