Hey All, I just recieved my AEM infinity 506 as well as what I have heard to be the last plug anf play harness available for the 2006 iX. Coming from tephra V7 speed density, I had a few questions anout how the sensors are cirrently hooked up, and what may need to be changed, ive read both manuals that came with the harness, and infinity.

quick back ground, I come from
the DSM world, have done all my own tuning on ECMLINK v3 with great succuess and have a fairly in depth understanding about how things work for our cars.

now for the Question: I’m switching to infinity 506 with the plug and play harness. I’m aware there is an aux input plug and harness for external sensors, (mostly aem marketed sensors) I have a GM IAT, using the spoolin up speed density cable, can Infinity read this sensor from the MAF plug? Or am I needing to wire the IAT directly into the AUX plug?

question 2: pretty much same qiestion for my Omni 4 bar, which is the MITSUBISHI style, and uses the oem MDP/MAP plug, can infinity read off this input using plug and play?

question 3: I have my AEM X series 4.9 LSU gauge and sensor tapped into my rear o2 input on the oem harness, I understand infinity has a direct plug for LAMBDA1 which is for a 4.2 LSU sensor, but can not directly use the 4.9 sensor. To use this I understand I need to hook up directly to the LAMBDA2 input on the aux cable using AEMNET, is there a way to read it off tue rear o2 I’m currently tapped into? Or is it best to direct into the AUX cable? All help appreciated. Trying to figure all this out before I tear into the wiring.

also From reading the manual, it seems that for infinity to control the idle speed controller stepper motor, I need to de-pin the two middle wires. Is that all?

thanks for reading and look forward to hearing opinions

 

Question 1 - Yes, use the wiring adapter for the MAF to IAT and it works just fine. In the Wizard menu, just change the setting to GM IAT. This is how mine is run.

Question 2 - Same thing. Use all OEM wiring, change the MAP sensor to OMNI 4 bar in the Wizards settings.

Question 3 - Wire it to the AEMnet plug with the AEMnet output from the gauge (just 2 wires). Dont use the LAMBDA input cable. Thats only if you are going directly from the sensor to the ECU. I have the same wideband as you and thats how mine is run.

Couple other things. The IAC needs 2 wires pulled out of it like you said. Super easy to do. Just pull them out and tape them off to the side.

Use the base calibration that AEM supplies. The tune will not even be close, but it calibrates stuff so that all the OEM functions work, like the cooling fan, tach output, AC and such. The only one I had to mess with was for the AC fan. With the AEM settings, it was only going half speed. Again, super easy to fix.

If you want a base cal that will speed things up for you, send me a PM with your email address.

 

Sub'd to remember these details

 

Just an fyi, the AEM PNP harness for the evo 9 is discontinued.

 

Hmm, I should just pick one up even though Im not ready to buy an Infinity.. If anyone actually has one.

 

I sent an email to my AEM rep to see if they have one more laying around for you.

 

Yep, AEM confirmed. You are screwed.

 

Hmm.. Not awesome. Maybe they are making something new or the Evo is just old enough and IX is obscure enough they dont care.

Soooo, Link or ball out with Motec

 

I'd spec out the Link and do your research ..

Motec is currently on Sale and still does exactly what you tell it to do . Its about 5-6K retail with everything and level two logging.

Unfortunately 5k+ is a non-starter for me. Just cant justify that much for adding logging capability.

I know Aaron at ER doesnt like Link so I was pretty well set on AEM but having every diff in my car fail really stole my winter budget. Trying to source a harness from someone that has one sitting on the shelf for now and can add the ECU later.

 

I could have sworn I saw an Infinity and IX adapter in the classifieds on here a couple weeks ago. Cant find it now though...

This look like the right one?

 

Yep, same part number as mine, just double what I paid haha.

 

Oh dang, wonder if people jacked up the price cause its going out of production... ugh

 

Nah $240 is list on it. I am sponsored by them so I get a bit better of a deal for personal stuff.
