The motor has nothing to do with that its the trans aslong as your trans is 3:54 you can use a stock 3:54 r160

The tuner forgot to change somethings in the ecu. Send me the Rom with a log and I will fix it.

First pull to 7k cut out at 6500. Tried it again and it won't go past 6500. Installed new spark plugs 1 step colder ngk and gapped them to .026. Car still will not go past 6500. Any ideas? It doesn't feel like fuel cut but more of a rev limiter....

The JDM 6mts I have worked with have all been 1.0 to 1. Its possible later JDM units up to current are 1.1. to 1. I honestly do not know but V7 and V8 are 1.0 6mts. The US car had a 1.0 6mt in 04 and some 05 later, They changed to 1.1 to 1 with a 3.54 rear. This make swapping into a WRX a snap as the WRX has 3.54 rear end.

Either way, You can swap the transfer gears in the 6mt without removing the trans and you can swap the ring and pinion in the rear end without removing it. So you can match it up one way or another.

How do I go about sending a log? Feel free to email me mrxr250rider@yahoo.com. I appreciate the help

If you dont have the means to pull the ROM and a log, let me know. We can meet up sometime. Im not far from you

All JDM transmissions are 1:1 as referenced in this comprehensive chart here:

hey guys i picked up a freshly swapped v8 into a bugeye back in june, just getting onto nasioc. since ive bought the car ive installed a manual boost controller and GFB 50/50 bov and a tune from phatbottimike. its a COMPLETE 2004 swap. so ive been having a small oil leak coming from what i think is the pan but its hard to tell, it gets everywhere. whats a common issue that this could be? im still learning a lot on this car, i had to jump on it for the offer i got so i never got time to study before hand.

If you can spray down the oil pan with brake cleaner and wipe it clean. Drive it a bit and check it again to get a better idea where it is

Is anyone running catch cans?
Would it be worth adding one to an ej207?

Just want to make sure this eninge goes at least 240k like the last one!

My ej207(second attempt) should be here Friday!

Not sure what people would suggest is better air oil seperators or catch cans. I plan on adding one when the 207 is on the road

my friend used a harbor freight aos from his breather tubes and it worked great. it was bright ass orange. its the kind for air compressors. about 6/7 inches tall. he emptied it at ever fill up. you would be surprised how much it caught from going into the silicone intake. if your car is having blowby issues then yes you need one because this misty oil will affect your tune and afr's.
if you do get a catch can make sure it actually has baffels in it and has good reviews. some places literally sell cans that are hollow but look sweet so ppl buy them the point is for there to be alot of surface area's in it so the oil hits the surface and sticks in the can rather than going into the intake tract.

All right, got the engine in and fired up......but I had to use a USDM WRX ECU to get it started.

I have a ver 9 engine swap and the ECU is acting like it's dead. I'm guessing it needs the matching immobilizer/key for it. Is it possible to get a new immobilizer and have the dealership sync it all together?

Or, can I get a ver 8 ECU that doesn't need an immobilizer? If I get that, will the pins match up the same as the ver 9 ECU? I feel like this option will be easier if it turns out that the ver 8 is pin compatible.

Thanks!

Ver9 JDM EJ207's do not have an immobilizer. 16bit ECU's are not capable to use one. You may just have a bricked ECU

Would a v8 ecu work fine (pins compatible)?

Some v9 do have immobilizer. The wiring diagram for them shows both possibilities.
The way to know is to look at what is pinned in connector A.
If you were to have the immobilizer and key, you would still need the dealer to reflash a different portion of the memory than is available to tuning software, to make everything work.
My theory is that in v9, the spec C did not have the immobilizer due to weight savings.
This mostly because the guys that run V9 on the board are spec C.

The S204 had it for sure , as I saw the special s204 key sold in a package with the immobilizer, on yahoo.jp.

I have yet to learn if one can reflash an ECU with a different model year rom completely. I read that if they are compatible, a complete image of a different year can be flashed.

90% of the time any oil in the intake tract is from overfilling the oil. Either Wrong dipstick (two lengths) or the car just has to much oil in it. If you keep it 1/8 to a 1/4 inch BELOW the line cold in the morning you probably do not need any kind of catch can.

I do not like systems that plumb to the oil fil cap and these WILL throw the tune off. I cap them off If the choice is mine.

The stock system works great unless, Its a serious road race car or its running over 25 psi of boost pressure.

what line do you use? i actually like to let my car warm up and i check it when i fill up every time. i use the warm fill notch on the dip stick to determine how much i need. i mean if its at proper levels when warm then it should be correct.

You can reflash a different model year completely on your ECU, but the ECU is only compatible with a rom "family", as outlined on Scoobypedia. Ex: you may lose AVCS if it is incompatible, due to NPS signal inversion intended for certain year trans, and other weird things happening.

There are some physical differences i've noticed when i've compared my v7 ecu to a v8 and s202 ecus that i've owned.

With this flash will it completely reflash the ecu back to stock no matter what tune is on the ecu? If so is this how the dealerships flash cars with ecutek back to stock roms?
