No one has used a vendor for their engine wiring harness and ECM tuning?

If anyone is wondering. The reason why I am concerned with the factory ratios is due to the fact that I will be running smaller tires and a different transmission. I also want to get good gas mileage and I do not want the engine to race (RPM too high) at highway speeds. My hope it that I can come close to what the factory came up with. I also need to be 100% sure of the correct rotation of a EZ36. Because I am looking into different transmissions. My guess is that they turn Clockwise. But I have not found anything concrete in my searches. Tony

Here is a chart I made yesterday to help me with my build. EZ36D 1st 2nd 3rd 4th 5th 6th Final Drive Tire Size RPM @ 65 3.105 1.983 1.454 1.057 0.779 0.543 4.111 30.047 1622 - 2015+ OutBack 3.54 2.264 1.471 1.00 0.834 - 3.583 29.043 2245 - 2014 Tribeca I have a question. I did a search on here and cars101 beforehand but was not able to find what I needed. On here I searched under "EZ36 rotation" to be 100% sure that the EZ36 does rotate clockwise like I think they do. The only link that popped up on here under that search, talked about cam rotation and how many degs. QUESTION: Does the EZ36 Rotate Clockwise? (standing at the front of the engine) Thank you, Tony

What vendor have you used for your Subaru transplant 1. to crack your EMC? 2. to make a power-plant wiring harness? Thank you, Tony

Thanks to help on the other thread. I was able to find the other info I needed. I believe I know what tire size came on EZ36D vehicles and what final drive ratio they also had. With that info I was able to put it into an engine RPM calculator to come up with the best transmission, final drive and known tire size combination that will fit in the project. It takes time but I am getting closer. Thank you again for all your help and support. Sincerely, Tony

Thank you very much. As long as the FINAL Drive specs under the transmission section is the same as what the REAR Differential ALSO has - I have figured out another step in the process that I needed. Tony

Thank you again everyone for your help and support .. I know what engine = EZ36D. I have worked out the wiring. But I still have a few things to figure out. If anyone of you have or know of someone who has a 2010 and up Subaru with a EZ36D and Automatic only - PLEASE check out the following thread below. I need more information to be able to run an Engine RPM - Speed calculator. This will help me to know if I will be able to run the power-plant in the factory sweet spot or not with my planned build. Right now I am only focusing on the Automatic. At my age I don't need any help to overload the brain. LOL http://www.ultimatesubaru.org/forum/topic/162811-where-can-i-find-the-following-information-thank-you/ Thank you for all your help and support. It is greatly appreciated!! Sincerely, Tony

My hope is that there are some members out there with the vehicle(s) I need the info from. I need the following information on 2010 and up with the EZ36D and AUTOMATIC only!! 1. What is the rear end final drive ratio? (I already have the ratio in the trans itself) 2. What size FACTORY tires are used on the same vehicle? (found on factory sticker) 3. What year and model vehicle do you have? NOTE: The above information will help me run an Engine RPM and Speed Calculator to make sure my planned build will be able to run in the factory sweet spot or not. Thank you for your help and time. It means a lot!! Sincerely, Tony

Okay. After your help and doing some more research EZ36 is the one. Now I have to find out if an Automatic and Manual for this engine can be Front WD only.

The Subaru instrument cluster is electronic and not cable driven, correct? I must say the last time I worked on a Subaru was back in late 80's and a lot has changed. Plus I have not done a Subaru conversion yet. So it is all new to me and a big learning curve. Not to confuse things, but to compare (and it is only what I know thus far) my current project has a sensor in either the transmission and/or differential. That sensor reads the given speed the vehicle is traveling and it is also based on the tire size the ECM was programed with from the factory. The RPM a tire will rotate varies depending on the O.D. I had to make 100% sure that there would be a way to change that info in the ECM or the engine would not preform properly. I just want to be extra sure that I can come up with some Subaru power-plants that will work on this other project idea. Thanks everyone for your help. It is greatly appreciated. Sincerely, Tony

Tire size changes the speedometer. On the current project I am working on changing the tire size** will change the readings the ECM receives. So I thought just maybe it would do the same with the Subaru ECU. ** Tire size on the vehicle I am taking the power-plant from for my current project uses 31" tall tires. However, the tallest tire I can use on my current project is 26" tall tire. So the tuner is going to have to change the tire size reading in the program of the ECM to get the power-plant to work correctly it the older vehicle.

Are people or TUNERS out there who can tune these Subaru setups? I don't know what size tires I would be using with this Subaru project I have in mind. With the current project I am working on I have to change settings for tire size and other items.

Thanks. I figured out the US. Grin I had no clue on the DM.

USDM engines?
