God I am waiting for this soooooooooooo bad

I am supposed to receive the first 5 production PCB sets this week. If all is well with them I will let them cut the first production run (100 PCB sets). In the meantime I am working on wrapping up the firmware. I figured out how to get the cluster to tell me the raw reading of the fuel level sender, so the numeric fuel level / range until empty won't require a wire to be tapped. I am now working on getting the ECM to give up the air to fuel ratio.

Scott, that left side vent mount will be perfect for me, especially in that orange RS glow with black backing...just installed RS trim pieces and a/c heater control knobs as well so black on black match.

My understanding is that he can read memory addresses but would need the machine code to write to the ECM. Reverse engineering the machine code is problematic, and Toyota doesn't share it.

Have I got that right?

That's correct.

I am making a bit more progress with being able to write to the ECM, for example I figured out the CAN message to make the ECM turn on/off the radiator fan at will.

For the question above about the AFR - The Yaris' O2 sensors are wide band zirconia sensors.

Well I am sure if you ever get to a point where you can do fuel maps, you will have a lot of people interested.

Just curious, what do you do? Electrical engineer?

Oil pressure is a funny one - The Yaris simply has a pressure switch that is on if there is oil pressure or off if you don't.

I am an Electrical Engineer,

Whenever you start taking orders for this I have my $$ ready for you.

i have a feeling this product will never come out, so many requests for more and more things to be adde, LOL I kid i kid.

In the Engineering world we call it "feature creep". Marketing people love it (not) when we Engineers keep wanting to add just "one more little thing" before release...

The best way to eliminate feature creep would be if the YarGauge were updatable via a serial connection... That would basically allow you to ship now and add features later on.

Then again, that would raise the final price for sure. Which I wouldn't mind doing BTW.

The tricky part to that is that it consists of two separate processors, each of which requires a different interface for programming.

^ and building a website for a client is exactly like that too!

POORSHA · 02-09-2010, 05:19 PM

And ordering take out is like that too

Tamago · 02-10-2010, 03:11 PM

i've asked before, i'll ask again..

since this is OBD2 driven, will it work on any other "like coded" OBD2 system? (my MR2) if so i DO WANT ONE

It's OBDII, but OBDII CAN, so it will only work for vehicles that use CAN bus (which is all vehicles 2008+ and many 2005+). Your MR2 is ISO-9141 based, which is one of the older hardware standards for OBDII. So, the YarGauge won't support your MR2.

So, by that it would work in an 09 Tacoma, I assume? Are there any Yaris specific codes in there or do you think the readings would work well out as long as he tapped the same wires?
One of the EE's in my office is looking to do this for his Taco' after I started telling him about yours... If yours is done already, I'll push him toward remote vent mount... I'm an ME, so this is all sparky stuff to me
