Wideband time offset
Posted: Mon Aug 02, 2010 2:19 pm
I find that 99% of the time my aftermarket WBo2 (AEM UEGO) is about an 1/8th of a second behind my OEM WBo2 in the datalogs. It does vary a bit though, some days worse than others. It would be nice to have a configurable time offset for the wbo2 in the graph view.
See the rich condition from the VTEC crossover represented in my A/F, then see that that same dip is registered by my WBo2 about an 1/8th of a second later.
I know I'm not the only person running into this issue. Also it makes using the wideband useless as a source for lambda overlay, as it causes it to put the wrong averages in the wrong fields. If you try to use lambda overlay you can end up chasing your tail around in circles trying to tune boost with it.
