ok, i've read about hondata and what it can do, but im confused on what it is. does it replace the stock ecu like the apexi power fc does? or is it a piggy back that can work as a stand alone if you have the datalogging and rom editor? please explain. thanks
it is a standalone. it does not replace the stock ecu. it works with it.
read up on it... hondata.com
basically, they put an eeprom (electronically erasable read only memory chip - similar to a computers CMOS chip)
from there, the hondata box talks to the ecu and makes the changes through your ecu out to the sotck harnesses- but hondata gets the readings in and then goes to the ecu.
make more sense? i know that wasn't a good description. liek i said, go to their site-- tons of info
in order to install it you need to solder in a 28 pin socket, a 4 wire ribbon, a 20 pin socket, a jumper, and two capacitors and two resistors. the blue box is attatched to the ECU by the 4 wire ribbon.
can someB help me, i got a few info, but still am a little confused.
my friend started to work in local honda service, and showed me "testing computer" wich has 3 different plugs for different ver. of obd.
1. my civic is 1.5 dx '93, and he told me that only thing i could do to check what signals my obd is receiving is to short connect 2 pins on connector, and light on the board will flash (error codes).
2. i am wondering is it possible to dl hondata software, and check pinout of "test comp.", make the cable, and connect it to ecu, without shopping from hondata hardware.
