Wideband Settings bug...

JaredKaragen · Post by **JaredKaragen** » Tue Dec 04, 2007 9:14 pm

I had to return the LC1 to my buddy; he uses it daily. I switched to my JAW, and after making the custom conversion table; I tried to calibrate the o2's offset; and the readout would lock at the min, med, or max values I put into the conversion table in the settings. The values are as follows: 2.87=28.70 1.47=14.70 1.05=10.50 The readout in ECTune will only display these AFR values, nothing inbetween; especially considering the slope is linear, I do not understand why. In the Diaplay pane the o2 voltage reads out and updates in real time, but the actual AFR number does nothing for me. ****Steps to reproduce bug**** \"settings\" -> Wideband pane. Predefined Wideband: Stock double click \"1.00\" for voltage, and clear the value to blank, repeat for the corresponding AFR. \"Save\" Error: \"Wideband Error: Input string was not in a correct format\" So my assumption is you would need to fill all of the cells that the last selected wideband had filled, or it will be of an improper input format. I then used the PLX-M setting, put in the JAW min, and MAX vout values/afr's, and presto! my logs now show a linear AFR, not locking between 3 values. Can you at this time add a voltage profile for the JAW? Please refer to the profile in the excel file I have included. ****Steps to reproduce bug****

interpolation between points should work normally. Retest again. I'll fix the bug to leave blank first

but the actual AFR number does nothing for me what u mean by this?

They are for setting up the wideband slope: \"Custom settings\" to define the wideband slope there is the table marked \"Wideband Voltage Conversion Table\" If I have narowband o2 selected, then change the slope values in the table to the ones in the picture, and blank out the unused 2 extra slope values from the narrowband default; it will error out. It will also set the predefined wideband to \"Custom\". *the problem might be in this step of code, maybe not releasing the table row count from the previously selected wideband* If I use theese values: volts/AFR 2.87=28.70 1.47=14.70 1.25=12.50 1.05=10.50 the program locks onto the narrowband profile for voltage to AFR display on the \"Display\" pane while logging and playing back; even though the logger still displays the correct o2 voltage; just not AFR. If I go back to the settings, and choose the predefined \"PLX-M\" it has 2 values in the table. I then change the 2 values in the table to: volts/AFR 1.02=10.20 2.87=28.70 The wideband display works flawlessly, and it doesn't switch between 3 afr values (low med and high). If you want me to video tape the steps and post on youtube, I am more than happy =) As for the excl spreadsheet; it is the actual values the JAW is programmed with when it is initially setup. It could be used to make a predefined WB for the list. (not sure if your referenced it)

i added the JAW and fixed the bug when you clear something. You can force update in 10 min. And replay see what happens

no prob =) got home a few min ago when I posted that. If I mentioned a screenshot; I forgot to upload it... lolz.

please don't post double i'll delete the other post.

sorry, I am just using the other as a backlog for myself; I will clear.

It will look like a bigger mess... I deleted already

fixed.

u tested it?

yep, I tried the blank bug, and it was fixed; sorry for the hasty reply; I meant to specify the blank bug was gone and the JAW profile works good, but the narrowband bug is still there, here are some screenshots. You can see in the datalog graphs what it should look like, vs what it looks like with the profile changed without selecting \"custom\" before changing the slope values:

With custom slope added without first selecting \"Custom\" Now, nothing loaded or closed or changed in the program besides selecting the JAW profile and saving the setting:

With the JAW profile selected Look at the AFR line, it shows what I am seeing.

as soon as you change something in the wideband convertion it goes to custom. I don't understand the bug. Try to be a bit clearer

JaredKaragen · Post by **JaredKaragen** » Wed Dec 05, 2007 1:34 pm

yes, it automatically chooses custom, btu the way the display shows the AFR readout is whacked and bound to the profile the last selected wideband had. In the case of a narrowband sensor, when you select it it counces between 3 readings; locking onto and displaying the closest reading of the 3... exact steps: load a datalog. settings menw->Wideband (using the wideband input through the o2 input wire) Choose narrowband WBo2, and save the settings, now, playback the recording; it locks between the 3 values (you might need to play with the offset to get 14.7 to line up with your log, but shouldn't have to) high, med and low, 10afr, 14.7afr, etc. It will playback the wideband AFR graph just as if a narrowband was hooked up. If you go into the settings -> wideband again, don't do anything but delete the last 2 values in the table, and put in this linear slope: 1.00=10.00 2.87=28.70 click on save and continue playback, it should still be displaying the AFR in that non-linear fashion, just like the narrowband......

here is the datalog
