I think the mi/empty is based on the rolling average so the value doesn't increase based on acceleration/cruise/coast/idle, etc. I'm not sure if it's possible in the controller you are using, but if so, can it be based on an average?

Doesn't matter... I'm still gunna buy it and I can ignore the value while accelerating.

I was working on the interface to the fuel level wire last night. and was thinking about that. I agree that the data needs to be averaged, otherwise the miles until empty would bounce all over (from 80 miles with a full tank while goosing it, to infinity when in DFCO).

Just lookin for an update.

Just waiting for the final revision of the circuit boards to come in. The latest rev adds the fuel level in gallons/liters and range until empty.

with all the revisions will this unit be able to do my daughters math homework ?

[kustom play]

cool im excited to pick one up!

I think so. Accuratizing of the fuel gauge data has even required the use of some calculus.

Sorry if this is either too late or stupid, but is it possible to get the air-to-fuel ration and the ignition timing?

And what's the refresh rate or response time for this thing?

hi CTScott

can the YarGauge be converted to Metric Canadian units like km's & such ....if so i really like to buy one ...thanks

looking also to adapt my laptop & tower PC to become a temp. OBD11 scanner , what can u do here CTScott

Yes, it will be configurable for US/Metric units.

A USB laptop interface will also be an option for the YarGauge. The laptop interface will provide data logging capability of all of the parameters that the YarGauge displays, plus as I figure out more Toyota specific things (like perhaps being able to enable or disable the seatbelt chime), those features will be added to the software for the laptop interface.

Any software only additions are still possible at this point. The hardware is frozen, but the SW is not.

Air to fuel ratio is not a standard PID for OBD, but the ECM does monitor it. If I can figure out how to make the ECM tell it to me, then I can add it.

Ignition timing advance is a standard PID, so that one is an easy add.

Right now I am running with the refresh rate at 4x per second (2x that of the scangauge). I can go wayyyy faster, but then the values become a blur.

Oh man, if I were living close by, I'd be begging you to let me assist you... even if that meant only bringing you coffee and donuts

This has became one of my favorite threads to check. One question I did have, is this going to be a one time production run or will they be available past the fist run?

wow, 14 pages to read oh brother lol. Wanna make it easy for me Scott? Any chance of one with A/F and Boost in the mix of ideas for this in the future. Or have I stepped in a pile of words already spoken? Thanks.

It will continue to be available after the first run.

A/F was just asked a couple of posts above. It is a maybe depending on if I can figure out the CAN command to get the ECM to give it to me (as it isn't a standard OBD PID). Boost would be a no, as it requires adding a pressure sensor.

@CTScott: You are the MAN! Please let me know when I can snatch one of those OBD modules of yours, since my carpc needs a fast one (the ELM unit I bought does not refresh quickly enough for me).
