hows it look

[jackedupcanyon]

Was able to open the tune file this time. You say you set the base afr vs. ect all to 12.5. Was this before or after the scan? Hoping after.

[jackedupcanyon]

oh and is there a way to smooth out the maf curve line withought really messing it up?

Hand smooth it out. I typically have it show the graph and make it as large as possible then hand smooth.

[Josh Hapka]

it was after.. loaded up the tune file for ya,,, um ill get another scan for ya whit this new one when i go pick up my wife...

[Josh Hapka]

infact i got this one,, i did this like a few hours ago check it out.... i really gave it hell..

[jackedupcanyon]

Looks like you still have a bit of KR at launch sitting still. Also according to your WB it looks like your WOT AFR is following commanded nicely but it looks like you are not following stoich and running rich in normal operation.

[Josh Hapka]

normal operations as in iddle and cruising?... wich kinda confuses me cause, when i tuned it for cruising it throws my wot way off... adn visa versa... adn also does it look like to you that my car still goes in to closed loop? is this bad?

[jackedupcanyon]

Yes normal operations - idling and cruising (non WOT) are rich. Need to get those right first then figure out why you car is not getting enough fuel during WOT.

STFTs are turned off. LTFTs do not look like they can not be turned off. I would reset the fuel trims the next time you go out to keep the LTFTs out of the way for a while until the car relearns them and reset again till finished. Are you wanting to disable closed loop permanately?

[Josh Hapka]

what is the purpose of closed loop? and was wondering if it is bad that my car goes to closed loop when i go wot and ill also reset the fuel trims and scan again...

[jackedupcanyon]

See if this link helps:
Open Loop vs Closed loop

[Josh Hapka]

yes that explains everything,,, now a problem accured today actually not to long ago. right after i fueled up with gas my ltft and stft went dead it said 0 no matter what.. the next thing is my 02 banks went dead but then would jump here and there once in a while, also it messed up everything with the histograms with the calculations cause before it with my cruising it was running between -5 and 5 and my wot runs were good, it commanded 14.7 during cruise and 12.5 during wot, but i dont get what is going on. cause now at cruise its commanding around 15.0 and stuff. when i would go wot it stills says my afr command is 12.5,, can you help?

[jackedupcanyon]

You turned STFTs off right? If you reset your fuel trims then the LTFTs would flat line for some period of time. That appears normal. Did you check your connections? Have you scanned again since and do you have the same issue? I would still focus on getting normal, cruise and non PE back down to 14.7 and eliminating KR before messing with PE and WOT tuning.

[Josh Hapka]

how do you turn off your stft? and ill scan again today as well as check my connection.it was just wierd though...

[jackedupcanyon]

Put the car in open loop.

[bilemke]

Tuning what will end up running as a stoich afr (areas of the tune you will not be running in PE in this case) with a wideband seems somewhat pointless to me, if not extra work that will not be used in the end. When you are done tuning with the wideband and let the car use the narrowband again, it will still make fuel trims again based on what it thinks is stoich and undue or defeat the point of the changes you made based on wideband scans.

Unless of course you plan on running open loop all the time..

[Josh Hapka]

ok here is a pritty good scan,

Your historgram 7 isn't right. Mine does the same thing and I'm trying to find the solution. It will not log the AFR Error %. It has the red star just like yours. Any idea why that is?

[jackedupcanyon]

Without Josh's config file, you are actually using your own config settings. Try reloading the HPT defaults and it should be "right". The red star is plot filtering - you are using some type of equation in your own histogram.

[98Camarod]

I'm using the one that was suggested in the other thread that posted, the same one as josh, except I substituted in AUX.20005 for my aem wideband.

His log doesn't provide the info under his histograms, it says its not supported. But the error % is on his table. What can you do with the information if it is just provided on the table, and not in the histogram to paste into the VE table?

[Josh Hapka]

maybe this should help to see what i see. maybe

[98Camarod]

I'm really new to this, but it would seem to me that you do not have the correct histograms setup to help you with your LTFT's. The only two histograms that have sufficient input to work are 1 and 2. Looks like your cfg is for idling only.
