Everytime you post that link costs me an hour looking around...

OK here's the start of OBDII flash, I did my part now someone needs to do the software...

Where's the pic and write up ?

[RobertISaar]

on my gigantic "to do" list.

thanks for sharing Robert, i will have to order one an try it out.

[supercoop]

would you look this over an see if my thinking is correct.

for 8192 applications

connect the RXD and TXD pins together(solder would be the preferred method), then connect that circuit to the ALDL pin M, then connect the ground pin on the converter board to the ground pin in the ALDL connector (pin A).

for 160 baud applications

You do not have to have TX and RX tied together. all you need is the receive part of the circuit, since it doesn't communicate in both directions.
so just connect the RXD pin to the ALDL pin E , then connect the ground pin on the converter board to the ground pin in the ALDL connector (pin A).

an set the voltage jumper setting to 5V, 3.3V might work, but it might also cause more problems.

.In TunerPro RT, set it to 4800 baud and uncheck RS232 echo and it should started acquiring data,

looking at the picture of the board ,i see there is allready a jumper across the TXD an RXD pins.
these are the pins you would connect the M terminal to, for 8192
or remove jumper an connect the E terminal to, RXD for 160 , Correct?

[RobertISaar]

could leave the jumper there, it won't hurt anything, and you'll retain 8192 capability.

would this work?

The FT232RL works so it looks good, however the only way to find out if that board in particular works is to try it. The signaling needs to be 5v TTL, not 3.3. It isn't clear if the jumper selects the signaling voltage or an output voltage of the board.

[RobertISaar]

i don't see where the jumper is intended to be placed to put it into 5V mode... i see a lot of 3.3v references, but no 5v.

i would ASSUME it would work, but there's only one way to know for certain.

[phonedawgz]

I don't see the jumper either, I'm just going by the text.

[71-nova-lt1]

what about this? i see a jumper to switch to 5v and i see the tx and rx ports

[RobertISaar]

that one SHOULD work, has the RxD and TxD pins required along with the 5V switch.

however, shipping times are pretty blah.

^{ok so i got the chip how to i set it up so the computer reads it and so does tuner pro}

grab the driver from here. install is pretty quick and simple.

then setup the correct COM port in tunerpro, load the right ADX and you're pretty much ready to go.

Wat can i use toflash it . I downloaded winflash but i cant find it
