| - | ====== AEMWB Logging Suggestion ====== | ||
| - | A number of people have various problems with the AEMWB display routine. There are a number of reasons for this, but most seem to revolve about the AEM's weak analog driver circuitry. It's simply unable to properly drive a number of ECU inputs. | ||
| - | |||
| - | 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. | ||
| - | |||
| - | 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. | ||
| - | |||
| - | One user found the following settings to work well on his own AEM WB install: | ||
| - | |||
| - | Min Voltage: 0.0 | ||
| - | Min lambda: 0.65 (gasoline A/F ratio of 9.55:1) | ||
| - | Max Voltage: 4.99 | ||
| - | Max lambda: 1.32 (gasoline A/F ratio of 19.43:1) | ||
| - | |||
| - | AEM has now come out with yet another mapping with their 30-5130 gauge (at least this gauge seems to have a separate analog ground, the brown wire, that should be connected to ECU sensor ground to improve the ability of the WB to deliver accurate voltage readings to the ECU): | ||
| - | |||
| - | Min Voltage: 0.50 | ||
| - | Min lambda: 0.578 (gasoline A/F ratio of 8.50:1) | ||
| - | Max Voltage: 4.50 | ||
| - | Max lambda: 1.224 (gasoline A/F ratio of 18.00:1) | ||
