i got a FAST dual wideband donated to me, can't wait to hook that up, and my sockets/chips should be here any day. should be a great excuse to test my fast-rate logging.

identified a problem that decreased wide band resolution (due to an integer conversion that I missed). also threw in a better wb config interface that lets you specify x, y for the afr point, so you don't have to understand linear math to get two-point configs other than 0v/5v correct. im going to provide presets for common widebands too. lt1+wideband+eehack=awesome in the next release....
I didn't even notice a problem with the wide band resolution. I have been using it exclusively for logging and flashing. It told me packet upload error, or something like that last time I flashed. It was successful though, so don't know what that was about. Haven't looked at the logs, been super busy. the wideband PE analysis is awesome though. Definitely helping me get wot dialed in. Was able to pull a 12.95@105.85 with rockers, headers, and drag radials in a stock stalled auto, so I think the tune must be pretty darn good. :)Originally Posted by steveo

another new beta, new wideband stuff needs testing, a few other misc fixes..
I have missed some great progress with the programm.
I will make some test with the new version and see how it behaves.
If you need free ad channel for true dual wideband you can use pin D31 and pin D27 they have 22.3kohm resistor and will have identical output.
PIN D27 is logged on tside at byte_103
PIN D31 is logged on tside at byte_11E
Also can you check if the actual voltage on the wideband output match the voltage on aldl log.
awesome, please test my patch to see if speed logging works, i've written all this stuff but i have no idea if it works yet!
kur4o can you please test and tell me how TCC lockup in mode4 works? the mode4 document we have seems unclear. i want to add a switch for it. i've already done gear selection.
is there anything else for automatic trans that would be useful?
i wish my bench testing setup worked right now so i could confirm in controlled conditions.Also can you check if the actual voltage on the wideband output match the voltage on aldl log.
im using x/51= to get the voltage, assuming it reads exactly 5v @ peak (linear 0-255=0.00-5.00v). i hope to check its accuracy properly later. i remember with an LM-1 i could never get the linear equation to work properly with the a/c pressure input, and was suspicious that it was actually reading 4.8v@255 or something.
as has been simulated and then tested real-world, the pulldown resistors in the A/D circuits can have a rather large effect on the linearity of a sensor read. either need more drive current(op-amp?) or more pulldown impedance, otherwise the linearity suffers and you need to build a table around known points.

What byte in the datastream is d31?
