OBD MPGuino gauge

[djarmyssg]

Yea.. Mine does the same thing... I created mine with a shut of switch, i just turn it off and back on again

[djarmyssg]

Here's a question. I want to change the MAP reading display from KPA to inches of murcery in vacuum, and PSI in boost. Anyway to amke this happen?

Wow!! This would blow my MPGuino out of the water! I had no choice when searching for a MPG and trip computing system. Would it be at all possible to use this with a 1989-90 vintage OBD1 (Chrysler Style) engine? I do have a supplemental Over/Under drive I can get pulses per mile from....It's only TBI, so injector Pulse Width isn't all that great as a measurement.

What do you all think? Is this doable???

i'm pretty sure this one is only for OBD2. sorry

Hello , i have a question in regards to JOBD , my Mitsubishi Galant '99 made in Japan , seems to be equipped with JOBD , that pretty much means that ELM will not work for me. As far as i see JOBD is included in the OBDuino code (at least i see it, searching for "jobd") ,so in theory it should work if the signals from the 16 pin connector are driven in to the Arduino ... how do i do that ? Is there an other suitable chip ?

Any help would be appreciated , thanks.

it is not the type of plug that counts, it's the protocol...
try to find out what protocol is your jobd running.

[largeK]

The exact protocol is MUT-II ,seems to be pretty common fot Mitsubishi even the Evo-s (up to 8) have it.

I have no idea what connector you got there, but after little googling around I understood that MUT is Mitsubishi specific diagnostic tool or protocol or something... as far as I know OBDuino doesnt need vehicle specific protocol, but general - iso, can etc...
jobd is japaneese standart for obdII. shouldnt the plug be the same as normal obdII?

[largeK]

The connector is the 16 pin OBD II-like one ,the data is оn the K line: Mut II , 15625 baud rate. I will try to get the exact protocol, probably not much different than OBD2 .

Anyone know where migght be the problem?
I have version 198.
When i upload the ELM code, it's just stuck on the screen "OBDuino32k v198"

I tried those things people said few comments ago, but no effect.
