Howdy all, I know almost everyone says accessport is dead but I had one and

decided to slowly learn how to tune my own car with the AccessTuner program. Now

my only question is on the program it states that you CAN data log using an aem

uego wideband but I just cant seem to figure out how to make that work. The

wideband works perfect it's just that when I connect the laptop to the ecu and try to

data log afr it says there is nothing attached. I know it has something to do with the

blue and white wires on the wideband but I myself have no idea where or what to

connect them to in order to make this work. Thanks!

 

I guess what im trying to ask is if the only way to log with a wideband while also

using the cobb accessport, is to go out and buy a RS-232 (DB-9) and splice the blue

wire from the wideband into pin #2 and have the laptop connected to both the

wideband and ecu. I'm leaning into the assumption that IF I could find the serial pin

from the ap connector couldn't I just splice into that pin and just have the laptop

connected to the ecu???

 

bumpty, does anyone even use the ATR program???

 

Not sure on ATR for the EVO is different or not but for the RX-8, ATR can log from an additional wide band but it only supports the wide bands from Innovate and PLX. I have a PLX mulitgauge AFR.

 

Reviving an old one... But I'm in the same boat, as I am trying to learn to tune as well. Found this page on Cobb forum.

I still need to order the serial to usb converter because all the electronic stores want 40-50 bucks for one.
