I cant get my computer to read the sensors. when i plug the usb cable to my computer, it sees in on com port 4. when its connected to the ecu, and im using ecucontrol data logger program, it says connected, but it doesnt read any values from the ecu. what do you guys thing it might be? i checked the wiring, its all ok. anything i should do software wise or whatever? is there like a common problem people face when it comes to this sort of stuff?

thanks

so is it supposed to work this way? i posted at pgmfi, but i dont think the forum moves as fast as honda-tech.

try swapping your TX and RX wires around.

do u have the driver installed properly?

baud Rate settings?

are you using USB or USB 2.0.. i had the same problem til i got a USB 2.0 port and it was all good from there.

I just doubled clicked the "USB DATA CABLE DRIVER" icon and it looks to be installed correctly. when i plug in the cable, the computer says its plugged in and ready to use. my settings are:
bits per second: 9600
data bits: 8
parity: none
stop bits: 1
fow control: none

is there anything else i can check? how do i know if its installed correctly anyways? when i go to device manager, it says "prolific usb-to-serial comm port (com4)

thanks

you have to have your ecu chipped with uberdata/crome and have the dataloggin enabled. otherwise you wont get any input from the ecu.

cool thanks. I'm really excited to know that i still have a chance to get all of this to work, i thought i was stuck and wasnt going to get anywhere. i have to wait a week for the eeprom burner though =/

taken out of context as both a computer geek and a honda junkie that is funny as hell....

i've never heard of this...why do we need to do that?

JDMlyfestyle

the j12 jumper keeps all data in the ecu. but if its cut it allows the ECU to send out data through the CN2

duh blacksheep

if i chip the computer, then i dont have to cut the j12 right? if i dont chip, then i have to cut j12?

BROKE.eg

no you still have to cut j12. it helps with data transfer.

duh blacksheep

if you cut j12, can you data log without the chip? are there any side affects from cutting j12 besides not beable to connect through the serial port?

no, you still have to have it chipped with data logging enabled. and no there are no other side effects.

cool, thanks you guys!

I never cut J12. People always argue the theory on full/half duplex whatever, but I decided it was best not to cut J12.
