One fix is to buffer the ECU input with [[http://www.ecmtuning.com/product_info.php?cPath=26&products_id=39|one of these]]. In doing so, the AEM is not required to drive the ECU input directly. | One fix is to buffer the ECU input with [[http://www.ecmtuning.com/product_info.php?cPath=26&products_id=39|one of these]].

- | People still seem to get varying results, though. So another fix is to simply not use the built-in AEM WB display routines and instead define your own using the [[linearitems|LinWideband display item]]. | + | People still seem to get varying results, though. So another fix is to simply not use the built-in AEM WB display routines and instead define your own using the [[linearitems|LinWideband display item]]. To use that, you change the pin assignment to be Linear wideband and then manually adjust the mapping. |
