GI: "YarGauge" replacement clock module (Digital Tach, etc.)

[CTScott]

What I'll most likely do is install 2-3 in relatively local cars. That way, if they find any issues that require software fixes, I can easily reflash them.

[swidd]

So who's moving to Connecticut with me? uuuuhaul!

[Lewis]

central NJ close enough Scott?

[dean_park]

If it's a serial reflash, I should be able to handle it. I'm a mechanical engineer but I dabble on the sparky stuff.. I do flash firmware on a lot of our equipment and our vendors equipment. I'm also originally from RI (even lived in Middletown CT for a year), so I used to be local....eh, probably doesn't help.
Should I just send my resume for consideration? lol

The YarGauge uses two microcontrollers - One for the display and analog inputs and the other for the CAN bus communications. The CAN bus one requires a JTAG interface for programming.

I live in Dayville ct and am willing and able to be a test subject. Ok not me but my car.

I'll volunteer! I live one town north of where you bought your car in south central MA. My 08 LB is best 14K I ever spent. I'm also very familiar with the tech side.

Hrmm I'm all the way in california but we use JTAG here at work to program our drives!

Noobs to the back of the line!

I have a USB JTAG Cable, I would buy a full working product when it comes out if it integrates nicely, I just can't tear apart my gf car just to test stuff :( Wish I could.

I hope these are finally available by Christmas!

I found a new LCD this week that I am hoping will overcome the sunlight visibility issue. It is an OLED display, which is supposed to have excellent sunlight visibility. I should be receiving my sample this week to test.

[IsLNdbOi]

Good to hear. I thought those things were in very short supply. How does using an OLED display affect the final price?

OLED displays are finally becoming readily available and no longer crazy expensive. The original LCD was costing me $12 and the OLED is $72 in quantity, but to have true daylight readability will be worth the extra cost. This display was over $200 when I looked at it a year ago.

Standalone devices like the scangauge can get away with <$10 LCDs, because of location. The killer for the YarGauge is having it recessed behind the smoked plastic of the cluster.

A non smoked lens will do the job as well right? maybe finding some way of reproducing the same lens but in clear and at the same time everything else will be mo readable during the day what will be cheaper the OLED display?

Unless it is Super-AMOLED, which I highly doubt, you have it backwards.

OLED displays are very nice and produce rich colors and deep blacks, but their worst flaw is daylight visibility, which is pretty weak. I wish OLED had great visibilty in the sun but they do not. The reason being is there is no backlight which is found on a traditional LCD. Instead, it uses a bioelectrical chemical to light and this washes out badly in the sun.

Just warning you before you make a mistake and buy them.

CTScott, I use to use this mp3 player back in high school - http://asia.cnet.com/reviews/musicpl...6925p-1,00.htm

It used OLED technology and I was able to read song titles walking around the border of the school during lunch time in the sun.
I don't think it should be a problem i the YarGauge as well because the cluster sits a little angled down in the area, doesn't it? it isn't directly sitting flat per say....at least when you install/remove it, it mounts a little tilted...

That was my impression as well. The VAR that is sending me the samples claims that they are a vast improvement over earlier generations of PMOLED displays. I guess we'll see. As Kioshi mentioned, the display is not in direct sunlight, so perhaps the high contrast ratio behind the smoked lens will do it. The gas gauge is just a backlit transflective LCD, but it is a higher contrast one than I've been able to source.
