Tried to use Calc.SELBEN can someone look at my log
Ok I tried the new method using my wideband. The non PE numbers look fine but my WOT afr is showing like 9 and 10:1 when before it was 13:1. But if you look at the LTFT BEN for the WOT it shows 1.02 and 1.04. Now this don't make sense cause a BEN like that in WOT means it's running lean doesn't it? I don't understand why my afr is in the 9's and 10's. and I have my PE set to alot lower than whats being logged so don't know why it's not kicking in either.

Tim:
Something looks totally wacky with your wideband. I have never seen AFR bounce around like that in closed-loop. Its like your WO2 is not grounded properly.
The formula calculated properly, but your WO2 is simply not accurate. Did you wire it differently on this log than before?
Tim, also verify that you are still running MAF closed-loop. You didn't disable the MAF did you? Either your airflow is perfect..because both your CYLAIR and DYNCYLAIR are perfectly identical.
Can you post up your Tune?
The only differences I made was he had a bung welded in so I can use NB and WB. And I went into logworks on my LC1 and changed the AFR from 14.7 to 14.63.
Yea your AFR reading are quite bizarre.
I am not an expert on WO2 hook-up, but I wonder if changing the Logworks might have had an unintended consequence of altering the internal EFILive serial conversion formula.
Most of us leave Logworks alone and just a CALC.Pid to figure AFR.
All I can tell you is that your Tune looks good, the formula calculated correctly, but your AFR readings are totally messed up. Like the scale was changed.
I would change it back and try again.
Yeah I just figured with the new formula i'd have to change the wideband. I'll swap it back tomorrow. But if you look at the ltft average % there almost all positive now where they were mostly negative before. Not sure why everything changed so much. It was foggy tonight, kind of cold and wet not sure if that would do anything or not.
Make sure you re-set the Trims prior to your next run.
Trims normally only vary +/- 2 to 3%..anymore than that then its a problem. Unless they got wet (NB's).
Try it again tomorrow..
I'm really not getting this. i basically started from scratch again using the CalcVe standard tutorial. I got my VE table in using the LTFT BEN and then WOT too, got WOT around 14.7. Then I reenabled the PE mode and ran it again, it lowered the AFR a little bit at WOT but not what the PE commands. It's only changing afr at WOT isn't PE what you commmand and not just at WOT? The problem I had before I think was somehow PE was commanding something super rich for some reason. I'm not getting it, it's not doing what it's told, just like a kid LOL. Now I know it's probably wrong but I have my PE enabled where I want and the VE table is good but it's still not commanding the afr i want so I manually calculate it and apply it to the VE table to get the PE mode richer.
Ok I logged calc.PE vs rpm and Map. It looks like it is going into PE mode but it's a factor it's not a complete PE. How can I change it so it will go into PE mode fully if there is a way at all.
Tim, what you are saying is not making a lot of sense...apply it to the VE table to get the PE mode richer. You never apply PE Mode to the VE Table in this method!!!
Its very easy to tell when you go into PE Mode..you last log you went into it normally. It was your wideband AFR that was not accurate.
Post your Log and Tune. We have to make sure your wideband is correct. You may be misinterpreting when you are in PE Mode.
