Wideband Settings bug...

the bug is still there with the JAW settings version r6?

nope the bug is still there, now; try these steps. Choose stock WB with an offset of -3.15 , and save settings. load my calibration, then load my datalog; you will see a narrowband output on the datalog graphs. Now, click on settings again, and click over on the tables of voltages/AFR's, and enter in the values: Voltage AFR 1.02 10.20 3.28 32.80 Delete the remaining values. Now, click save settings and you will see the graphs remain incorrectly displayed; and if you play it back it won't display the correct values. if you go into the menu and select the JAW profile, it will display correctly. You see the bug? You can also do it this way: Choose stock WB with an offset of -3.15 , and save settings. load my calibration, then load my datalog; you will see a narrowband output on the datalog graphs. Now, click on settings again, and select \"custom\" wideband, then enter the values into the table: Voltage AFR 1.02 10.20 3.28 32.80 Delete the remaining values. Now, click save settings and you will see the graphs remain incorrectly displayed; and if you play it back it won't display the correct values. ***WARNING, please, do not try driving on this base anyone =)

Stock wideband? I think you mean stock lambda sensor? And how do you get a offset so high? -3.15 is a lot! Dont you have some other problem?

-3.15 AFR offset? WTF are u doing.. I test my interpolate routine just now. It's very simple just a formula. I think -3.15 does something u don't want Normally it works like this (Volt->AFr)-Offset=Final afr

I know, I know, It is the amount it is taking to get the AFR on the WB02 to match ECTune. I used the LC1 to make sure it was calibrated corectly, and reading correctly; For some reason, with my WB02 turned off, my ECU reads around 1.2-1.5V I have noticed I need a larger offset with my DIY WB02, still trying to fix that issue myself. I am going to try re-wiring and re-locating the WB02 controller. But I take it you saw that bug now...

If I remember correctly, the old DIY WBO2 output isnÂ´t linear. So be careful

This one is pretty close to linear. It was designed that way so you can use a voltmeter to display AFR =), but these logs and values are only to show you what it's doing; I can get a good AFR reading, and the adjustments I am making are correcting the AFR's, so that isn't a big problem for me right now; But I will be replacing the JAW in a short time; I am just needed to buy other things such as a new mani, etc. it's the fact that if you are using the narrowband profile, then try to put in a custom value from there, wether you choose custom or just click on the tables and modify them, it will still show on the datalog graphs and the gauges the profile of the narrowband even though the slope (tables) are configured correctly. I noticed this bug when I first went to try and setup the JAW. It's a trickly little bugger; but it did weird things before the tables bug was fixed; but the bug is still there with the display after changing from the narrowband input. Now that the JAW profile is in there, if you select it; it works like a charm. I have been working on settling the offset issue I am having; it will include trying a new grounding/power method for the JAW, and switch off the narrowband o2 input on the ECU, and probably use a free input or a useless one (such as the power steering pressure switch).

you can not use a PSinput as wideband input. Only ELD, B6, EGR, O2 input. PSinput is oin/off switch input... THe other are 0-5v.. I can't reporduce the bug.. You talk about Stock WB with an -3.15 offset. I don't have the preset Stock wideband in ectune.

Jaw profile is not linear.. can u send the xls sheet again..

Post by **calvin** » Mon Dec 17, 2007 8:45 am

i think this has all todo with you setting up of scalar i remeber that the jaw scalar is not linear at all.. The values 1.02 and 3.28 u put in are way to weird for me... Test futher and report back.. Check the sheet u send it's not linear... Other wise i would put in so much data for the jaw.

close to linear; but I was just inputting the values to get a result before... I will video tape and post on youtube what is happening.... It's a sneaky little bug; but I will show =) The reason the values seem odd compared to most WB02's is because of it's initial design principal: a WBo2 that you need minimal extra stuff to use: so the VOUT (scalable outputs) are defaulted to go between 1.02 and 3.28Volts because that is the closest range the ECU can work with; and also because it was meant so that you can hook up a voltmeter to display AFR on the voltmeter.... Will report back tonight.

post exact steps and log file again. What input u are using.. Make a log file post what i should see what is wrong and everything with the exact ectune names. stock wb i don't have that so i couldn't debug..

Ok, now I am trying it, and it is not doing it.... I dunno what is going on; but it's not happening again. Ok, the way the JAW is linear; it is; but it is a number that is rounded to create the corresponding voltage: 34.28AFR = 3.428v (Rounded to the hundredth of a volt) = 3.43v The AFR to volt equation is linear; just in a crude way because it is being converted backwards from AFR to Volts, not the other way around. Full JAW conversion table. AFR Lambda Vout 34.28 2.33 3.43 33.26 2.26 3.33 32.28 2.2 3.23 31.33 2.13 3.13 30.43 2.07 3.04 29.56 2.01 2.96 28.73 1.95 2.87 27.93 1.9 2.79 27.17 1.85 2.72 26.43 1.8 2.64 25.73 1.75 2.57 25.06 1.7 2.51 24.41 1.66 2.44 23.8 1.62 2.38 23.21 1.58 2.32 22.64 1.54 2.26 22.1 1.5 2.21 21.59 1.47 2.16 21.1 1.44 2.11 20.62 1.4 2.06 20.17 1.37 2.02 19.74 1.34 1.97 19.32 1.31 1.93 18.93 1.29 1.89 18.55 1.26 1.85 18.18 1.24 1.82 17.83 1.21 1.78 17.49 1.19 1.75 17.16 1.17 1.72 16.84 1.15 1.68 16.53 1.12 1.65 16.23 1.1 1.62 15.94 1.08 1.59 15.65 1.06 1.57 15.37 1.05 1.54 15.1 1.03 1.51 14.7 1 1.47 14.68 1 1.47 14.53 0.99 1.45 14.38 0.98 1.44 14.24 0.97 1.42 14.1 0.96 1.41 13.97 0.95 1.4 13.84 0.94 1.38 13.71 0.93 1.37 13.59 0.92 1.36 13.47 0.92 1.35 13.35 0.91 1.33 13.23 0.9 1.32 13.12 0.89 1.31 13.01 0.89 1.3 12.91 0.88 1.29 12.8 0.87 1.28 12.7 0.86 1.27 12.6 0.86 1.26 12.51 0.85 1.25 12.41 0.84 1.24 12.32 0.84 1.23 12.23 0.83 1.22 12.14 0.83 1.21 12.05 0.82 1.21 11.96 0.81 1.2 11.88 0.81 1.19 11.8 0.8 1.18 11.72 0.8 1.17 11.64 0.79 1.16 11.56 0.79 1.16 11.48 0.78 1.15 11.4 0.78 1.14 11.32 0.77 1.13 11.25 0.77 1.12 11.17 0.76 1.12 11.1 0.75 1.11 11.02 0.75 1.1 10.95 0.74 1.09 10.87 0.74 1.09 10.8 0.73 1.08 10.72 0.73 1.07 10.64 0.72 1.06 10.57 0.72 1.06 10.49 0.71 1.05 10.42 0.71 1.04 10.34 0.7 1.03 10.26 0.7 1.03 10.18 0.69 1.02

post the excel sheet please

JaredKaragen · Post by **JaredKaragen** » Tue Dec 18, 2007 2:58 pm

Ok, Here is the latest Vout table from the newest JAWEdit. There are new profiles added to the JAW to simulate a stock o2, and LC-1, etc. but those are selectable in the JAW adding more versatility to the unit... so you can use the narrowband scale or any other... fully programable =)
