My tuner recommended I use an Osiris instead of my Haltech, so I'm selling the Haltech and the wideband I used with it. It's one of the red ones and comes with the harness. I ran the Haltech and wideband for about 5k miles. Everything works as it should. The wideband was wired into the Haltech for power, ground, and of course the sensor input. These wires were cut to remove the UEGO from the car, so this will need to be re-soldered to run the wideband. I'm asking $900 shipped for the pair.

AEM unit is part number 30-2310, this is the one with no gauge. It feeds directly into the ECU. http://www.aemelectronics.com/wideba...k6dggnb20bc7b6



Please let me know if you have any questions, thanks!

Still have this. Open to offers

 

Still for sale, price dropped to 900 OBO

 

Excuse my ignorance but what's the difference between the standard haltech unit and the red box

 

There are 3 haltechs, two pro harness models and one pro plug in model. The two harness models rely on the factory ecu to handle things like OBD communication, gauges, throttle body, etc. The pro plug in completely replaces the factory ecu.

The two harness models only differ in the O2 connections. The red model is older and needs two wires soldered to run an external O2 sensor. The silver model has a separate breakout to run the haltech branded wideband without cutting any wires.

 

In terms of features and tunability, the only major difference between the harness and plug in units are the throttle body control. This really isn't an issue unless you want to raise your idle.

 

Is it required you use the onboard wideband function cause I already have a AFR gauge in the car. Also how difficult is installing with the harness I've only ever installed the pro plug in unit. I'm def interested just wanna make sure I can actually use it

 

If you want your wideband tied into the haltech for logging and afr correction, you need to take the 0-5v output from your sensor and connect it to the 2 sensor input wires on the haltechs harness. From there you enter the voltage curve from the widebands manual and you're good to go. The harness is only about 12 inches long and connects directly between the two ecus so it doesn't take any skill to install.

 

Now if you don't want to use O2 feedback, you can leave the wideband wires detached or reconnect them to the factory sensors. Then you just disable the O2 functions in the haltech software. I really recommend having O2 feedback enabled though, the car will be somewhat more forgiving of an imperfect tune, and will be able to compensate for things like weather or changes in altitude.

 

SOLD! Thank you!
