Summary

This Wish List is a place for people to put up ideas and requests for features. There is certainly no shortage of items to develop, and putting your idea on the list doesn't mean it will be developed. However if it's not on the list, then such features are even less likely to be developed. So lets keep a list to help steer the long term features. If you have an idea or feature please add it to the list, and perhaps someone will make it a feature.


Short / Long Term Fuel Trim LTFT / STFT

Description

Many OEM vehicles predict what amount of fuel should be delivered. Then they measure via O2 sensor if the prediction was rich or lean. The short term is calculated as fast as possible and is used for short term fuel adjustments. Then the STFT is averaged out over the course of several minutes, that long term average becomes the LTFT.

Suggestion on how

Not sure exactly how. It would be a software item, so it would likely be added into the fuel calculations as a software item.

Misc notes and links to help show the request / idea

For OEM vehicles, it's common that the LTFT is up to 2% due to MFG tolerances and such. If you get to above 5%, it's typically a preliminary warning that there is something wrong, perhaps a wearing O2, or air leak in the intake or exhaust, or plugs with an improper gap. If the readings get up to 10%, generally you'll start to see emissions system fail and the MIL to activate. Such a systems are very handy for diagnostics of OEM vehicles, it would be handy to have that kind of feature here for similar diagnostics.


Long term diagnostics like Freeze Frames

Description

Freeze Frames are handy for intermittent issues. It would be handy to have similar logging for diagnostics purposes.

Suggestion on how

This is a software item that involves many pieces of software.

Misc notes and links to help show the request / idea

See standard OBDII tools for typical Freeze Frame data.


Diagnostics self checking

Description

Many OEM vehicles monitor things and check items via multiple cross checks. For example, they predict the fuel, and spark advance, then if the O2 sensor indicates a rich or lean mixture, it tosses a MIL light, captures data automagically, and preforms some corrective actions, like going into limp home mode, ect. Adding such features would be a handy diagnostics feature.

Suggestion on how

Not sure exactly how. It would be a software item, so it would likely be added into several layers of the software as a software item.

Humidity calibration / adjustments

Description

Humidity changes many parameters of combustion. It will display O2 which will slow down the flame front and decrease combustion pressures. It will change the airs ability to pull heat away after combustion. Both have significant influence on horse power and efficiency.

Suggestion on how

Allow adjustments to the fuel calc based on this sensors in put. Also perhaps adjust the ignition timing, as it changes the flame front speed. Which changes how far you can advance before detonation- and ping.
