AEM Infinity Tuning
This may be the wrong area, but I feel like the Tuning area doesn't get nearly the attention.
I am stuck... I need a GOOD, RELIABLE, Tuner to help build me a base map so I can get my car running. I have two tuners in my area that both have not lived up to my expectation of customer service.
I am in the Madison, WI area and running AEM Infinity. I am not looking for something for nothing. I will pay a reasonable amount for a base map that can get my car running so I can leak test and what not before getting it tuned.
I can send the base map I have already (car wont run on it, keeps flooding out right away) along with a list of modifications/pinout for custom harness.
Thanks.

oh wow. yeah I hadn't heard much from him in a while, but didn't realize that he had fallen off. Sorry to hear about that.
PM sent to OP. It's not really straight up e-tuning (the "I just put a downpipe on my stock WRX, tune my car for me plz k thx" kind) but maybe the tuning group can support the effort.

Thank you for the replies. It is to bad IR is so far away or I would bring the car over.
arghx I will PM you back. I have the map pulled from the computer along with a log about 19 seconds long (one of the only times I could keep the car running... at 2800 RPM).
There is one option here that I am waiting to hear back about, but I have tried to get a hold of the guy in the past with zero response.

Have you tried starting from scratch with the initial setup wizard? That plus the instruction manual provides some decent information on getting the car to idle.
Read up on Supernaut's build thread. They installed the infinity a few months ago and Brian may be willing to help you.

Post a copy of your map and a log of the car running and I'll try to help. I've tuned a few cars with AEM Infinity ECU, including my RX-7. I have a couple of additional questions:
1. Which MAP sensor is on the car?
2. Does the engine have the Idle Speed Control Valve installed, or did you remove it?
3. Does the engine have the coolant lines and thermowax valve on the throttle body, or did you remove it?
4. How is the ECU measuring AFR? I saw in your build thread that you have a wideband gauge, is that connected to the ECU?
5. If the wideband gauge is sending AFR info to the ECU, have you confirmed that the numbers on the gauge match what you're seeing in the software while the engine is running?
6. Is there a fuel pressure sensor connected to the ECU? If not, do you have some other way to check fuel pressure when the engine is running?

I am currently working with someone I met on here to go through all of the issues he found with the map from another shop, and a couple issues I had with my setup. To answer your questions:
1. Which MAP sensor is on the car? GM 3 Bar
2. Does the engine have the Idle Speed Control Valve installed, or did you remove it? Removed
3. Does the engine have the coolant lines and thermowax valve on the throttle body, or did you remove it? Removed
4. How is the ECU measuring AFR? I saw in your build thread that you have a wideband gauge, is that connected to the ECU? It wasnt, I had the wideband going to the gauge, then the 0-5v signal going to the ECU. This is one of the issues I have fixed, and it is wired into the ECU.
5. If the wideband gauge is sending AFR info to the ECU, have you confirmed that the numbers on the gauge match what you're seeing in the software while the engine is running? I will be confirming this once I get the revised map.
6. Is there a fuel pressure sensor connected to the ECU? If not, do you have some other way to check fuel pressure when the engine is running? Yes, but I also have a gauge on my FPR in the engine bay.

1. Check the part number on your GM MAP sensor against the sensor that is selected in the software, you can find this by opening Wizards>> Setup Wizard, go to the 'Basic Sensors' page and double-click MAP sensor to bring up which sensor is selected from the dropdown list. There are a few different GM 3-bar sensors, and if your ECU is configured for a different one than what's on the car it will be very difficult to tune the engine.
2. If possible, I would recommend reinstalling that IACV, it's really too much of a compromise in just about any circumstances. Without an idle valve, you are stuck with the same amount of idle airflow when the engine is hot or cold. This results in either a car that needs throttle to run without stalling when cold, or a car that idles too high when warm.

Thank you for the advise. I did already make sure the correct MAP sensor was selected (it wasn't at first).
My next biggest hurdle is finding someone within a reasonable distance to me that can tune the car. I will have the car running and driving but the closest place I can find, right now, is 7.5 hours away. I am starting to wonder if I need to start a thread for the WI/IL area to fly someone in that knows Infinity and have 4-5 cars waiting for him/her along with a dyno rented.

Did you ever get it running? My setup is far from stock, and mine idles just fine on the AEM supplied base map. There's plenty of correction to compensate, provided you have everything setup/wired correctly. Understanding all the options in the setup wizard is where most go wrong, it wasn't dumbed down enough for me. There's a good hour long video on YouTube by a boat performance shop that goes through each step, definitely worth a watch. Also don't forget AEM's tech support, I had good luck with both their forum and calling. Exchanged a few logs and sorted out my issue (GM throttle body configuration)
