Tables change by themselves??

[DrX]

Made a few tweaks to my tune(OLSD) the other night. Reflashed the next morning, started up the truck and noticed that commanded fuel after warmup was at 15.28 AFR rather than 14.12 as in the last log on the previous day. I checked my B3647 commanded fuel table(COS3) which has not been opened for several weeks and all of the values had been bumped up. Any cells that were 14.12 were now 15.28.

I fixed the table and reflashed. Now today I opened up my tune and checked B3647. All the 14.12 values are now 13.58! What the heck is going on? Could this be related to the other strangeness I have going on? http://forum.efilive.com/showthread.php?16822-Strange-injector-and-timing-behaviour

I do recall some kind of EFILive error message the other night before I became aware of this issue.

Hi DrX,

Did B3601 change at all...?

[joecar]

What is your B3601...?

You should change fueling unit to EQ.

[DrX]

B3601 is 14.12, same as it was yesterday. B3647 has changed.

[joecar]

BTW: whenever you change B3601 or the fueling units, you have to exit the tunetool and restart it to have B3605/B3647 display with the new stoich/units.

The PCM's flash contents can't change like that, it's not possible.

:)

It's not the PCM where its changing. It's the tune file on my laptop that is changing without me opening B3647. So when I perform a reflash to update another parameter, B3647 gets chnanged in the PCM at the same time without me knowing it.

Yep it happens quite often. A couple of build versions ago it was changing the values. After I would make a change, close tune tool, open tune tool it would bump itself up by a half point. It would do that to all the tables I would change. This build number seems a bit better as it only changes a quarter point or so.

It might just be a rounding situation where EFILive has to adjust up/down to the nearest possible number.

[DrX]

I am familiar with the rounding. I have been using EFILive for about 6 years. But the AFR values were increased by around .4 the other day and decreased by around .6 today. I am a few builds back on 7.5, but I cannot download the most recent until I get back home next week due to my extremely slow internet connection where I am now.

[joecar]

What build were you using when you posted post #9...?

[slows10]

I wasnt refering to a rounding issue either. I might have made it sound like that.
