Paul thank you for your help on a few questions I had. Next thing to do is to fix my O2 wire - it's connected on each side of the harness - but there must be a contact issue because it's not seeing any signals.

Yeah soldering isn't too hard. Tinning the wires first makes it super easy.

hey b you talking about getting the fic to read your wide band? Im having the same issue, iv connected it as per aem's instructions and set it up on the fic but its just not reading it. I double checked my connections with a meter and im getting a 0-5v signal from my wide band but for some reason the fic just doesnt see it. Im wondering if the aem instructions ar wrong and its a different pin on the fic. They say pin 18 on the 22 pin connector. Iv triple checked the location and cant for the life of me figure out where els it could possibly go besides on pin 18.

We need to ask Garabaldy about that one. I think he's running a PLX just fine with his F/IC.

crush02342002 01-22-2009 09:17 PM

im using the aem uego, same 0-5volt output so same thing....im running the latest and greatest software (3.04), flashed my main chip with x300.hex and flashed my slave with z104.hex. connected the wideband to fic as per aem's instructions, set up the aux gauge, so what gives. if you find out let us know asap..

I heard about this trick a while ago. The problem that this thing fixes is a small studder in the power at like 4k RPM right?

and i dont know why but i cant lagg the turbo, if i do, the car will jerk,my tuner drove the car and he said that he cant figure out whats wrong. and no money right now to take it to someone else.

i have ECU pinout diagrams, just need to know what year car, you can find em yourself on the tech section of the dezod site.....getting a harness will make it so much easier / reliable for you.

w/ the ecu pinouts you can wire up the universal harness as long as you have the manual from greddy so u know what wire does what....but still look into a boomslang or somthing.
