why is this program changing to semi open loop when I close it?

[louis]

I am having a really bad experience here with this program. I am running in open loop and when I close the program or at random it also does this when trying to add a new tune. It changes B3601 and B3647 to the same stoich when ever it pleases.

Not only that but it is so bad now I cant even use this program anymore to tune. I can see my stoich on my lm-1 is a good 14.6 at idle but the program even when in open loop is calling for 15-25% more fuel everywhere.

Digging even deeper I also see my table B3618 is changed from 14.63 to 14.7 which was the value of of B3647 and seems when the program changes B3601 abd B3647 to the same stoich it also takes B3618 with it and all end up with 14.7. The values I use when in open loop for B3601 was 14.70 and B3647 was 14.63.

It doesnt matter what I adjust either. It is so bad I parked my car and have no further interest in even driving it till this is solved.

I'm having a hard time following the problem. Any chance you could post some screen shots and/or the tune so we can help you out?

Hello and thanks for the quick response.

It is very confusing but here goes. I redid the tune to bring back these three tables to autove tune open loop. B3618, B3647 and B3601. These are the tables that change every time I close the program.

Please look at the three tables from above and you will see what it did when I closed it and then reopen it. The three tables above were exactly the way the autove tune tutorial shows before I closed it. This is the end result.

Thanks

Hello gentlemen.

I made the mistake of changing B3601 to 14.7 while I kept table B3647 non enrich fields at 14.63. I mistakenly assumed that these 2 tables had to be different in order to maintain open loop.

That part is actually correct that they do have to be different but B3601 has to stay at 14.628573 and B3647 in non enriched areas needs to be 14.5 or 14.7 to maintain open loop.

Hope this helps anyone who may make the same mistake as I did.

Thank you all for your help.
