Final Thoughts
If you are looking to have your 2005+ Toyota ECU tuned, the main tuners I've found that specializes with these are R9K Tuned and Orangevirus Tuning. I went with R9k Tuned for my tune.

I didn't have too much expectations from the tune for much power increase and I was pretty much right. It's a given since the engine is overall stock with only really minor modifications. The power difference between the stock and tuned ECU is just about the same except the low end power has increased. This I sorta felt after I installed the tuned ECU and started running 91 octane. Overall I am happy with what I got and I may eventually add more modifications and get the ECU tuned more one day but that day will not happen for a very long time.

I've also noticed a slight mileage increase with the tuned ECU. Typically by the time I reach halfway point with 87 octane with the stock ECU it's tended to be about 180 miles. With 91 octane and the tuned ECU it seems to have gotten to 200 miles. This is with my normal driving from home to work and minimum driving to stores (assuming I am not driving aimlessly).

As we know and/or searched, there is not much dyno data for a Gen 6 Camry let alone for the 2AZ-FE at stock. The only info is just the specs handled out to us whether by Toyota, Edmunds, AutoTrader, etc. I hope this data can be utilized for any other people who want to do more for their Camry, just make sure you got the money, contacts, resources, time, and the skills to make what you want come to life.

Stock Dyno Pull
144.42 HP at 5930 RPM 145.32 ft-lbs at 4170 RPM
144.09 HP at 6000 RPM 142.62 ft-lbs at 4870 RPM
144.38 HP at 5950 RPM 144.66 ft-lbs at 4060 RPM
Tuned Dyno Pull

Final Baseline: 143.98 HP at 5890 RPM 147.37 at 4040 RPM

I swapped my ECU with a ECU from eBay for about $50. I was able to get it working with the paper clip method. The only issue I had was that I broke a bolt from the ECU bracket that sits near the strut and I broke the connector clamp hinge. Even though the hinge is broken, the clamp still works... it is just removable now. I plan to zip tie it as a precaution.

ECU Removal
  1. Match ECU part numbers
  2. Disconnect battery
  3. Unclasp ECU connectors (be careful and I recommend waiting thirty seconds before unclasping it)
  4. Remove air-box
  5. Either remove airbox & ECU bracket or remove four screws from the ECU
  6. Remove ECU

ECU Resync
  1. Key ON
  2. Turn off all accessories (radio, blower motor, etc.)
  3. If you have a old or weak battery, make sure to add a trickle charger to make sure the battery does not die
  4. Obtain a jumper cable (paper clip, wire, two T-pins soldered to a wire, etc.)
  5. Jump the connector holes that are highlighted
  6. Wait 31 minutes
  7. Key OFF
  8. Remove jumper cable
  9. Make sure vehicle starts

What connection do you use the jumper on? OBD connection?

OBD2 connector is right.

ECU came back today and I hooked it up. I didn't feel much of a difference but I don't exactly expect THAT much to be changed given how light the modifications I have are. It does rev up to 7000 rpm so that is a difference I can see. I don't plan on putting in any 91 octane yet as I still need to dyno the stock ECU which will happen on Friday.

This thread is very interesting, and I'm surprised that the drive train loss is not that much. I have two questions to ask: Are you looking for any power goals for you Camry? Will you consider boring out your plastic intake manifold or will you go after market?

Car Ownership History::
06 Camry LE 2.4L 2AZ-FE
02 Outback 2.5L EJ251
03 Lexus ES300 3.0L 1MZ-FE

I don't have much power goals for my Camry as I do not have the funds to do anything like that nor do I have any contacts or skills to do it. Most of what I am doing is what I would consider as a "light" build because I am really only searching for the bolt-on parts that are currently available for the Gen 6 2007 - 2009 Camry with the 2AZ-FE. Those parts being the K&N CAI, Megan Racing Catback, Weapon-R Throttle Controller, and a tuned ECU. I have thought about removing the secondary catalytic converter as it is not monitored but I figured I might do that when the flex pipe rusts away. Anything else is mostly gonna be custom or internal.

I have thought about getting an aftermarket intake manifold as there are plenty for the TC's but my only fear is that I am not sure how much space there is to fit it. If it don't fit, then it is not worth it. I have heard about throttle body boring and am interested in getting that done to mine. However that is a bit low on my priority list.

I have thought about getting coilovers or lowering springs but since this is my daily driver I don't really consider those a choice. I live in Southeastern Wisconsin where the roads are in bad condition and the weather can go from nice and sunny to a huge snowstorm in a single day and with my driving habits I risk hurting my Camry. I do want to get a nice set of 18" wheels as I am hoping their lightweight and more tire will help make the Camry feel a bit better along with a set of 16" stupidly neon green wheels for winter use.

Updated with final tuned dyno baseline and thoughts. I will add the dyno sheet soon and will update this thread when that happens.
