Samurai Jack - I've tried every possible way to reset the system according to the instructions, but no go.

I'll have to drain and fill with the proper ATF fluid for the Power Steering.
We have only driven it about 5 miles after swap.

Just got my saabaru with v8 ej207 swap at a steal price. Problem is my area does emissions testing via obd2 port. Now i have to go through some pain to get it to pass inspection

In NY your ecu and vin numbers have to match, in the case of a new ecu the dealer has to encrypt it to match the vin. I hope you got the original ecu also when you purchased the car. The original ecu can idle the car but not so well due to the different fuel injectors on the STi motor. If you need a stock 05 wrx ecu let me know, I have a good spare I can sell you for $100, pm if you want the ecu or have questions.

yes emissions are a tricky battle because they vary immensly from state to state and country to country. apparently people near me have told me they passed with a jdm ecu & catless. they just had all the readiness monitors set to force pass. plugged in, everything was a-ok, away he went.

Has anyone had any issues with running Learningview/Romraider/EcuFlash on windows 8.1?
I tuned the car back in 2013 (02 w/ v8. Tuned by Ron @phatbotti).
The car recently has been getting wonky AFR's at cruising/idle. Bouncing from 14.1 to 15.3 and such. Its about time for spark plugs/timing belt etc. but wanted to hook up a computed and read a random CEL that came on briefly yesterday.
I no longer have the windows 7 laptop i used to tune the car but do have one running windows 8.1.
I downloaded Learningview and got nothing. I downloaded ecuflash and romraider and got a little. Romraider logger doesnt show a com port connection BUT was reading off the ECU for a few minutes before it automatically stopped.
I have java updated (i think only 64bit?), enabled .Net 4 or whatever that enables .Net 2.0.
Computer is running windows 8.1, 64 Bit. Using Tactrix 2.0
Any ideas?

Windows 8 is just pure trash

I have only done logging on a windows 7 laptop for that reason and licences are only like $50 now for 7 Pro

I do not disagree. I unfortunately only have the one computer running 8, and is also running Solidworks so i dont want to go back to 7.
I am ready to throw my entire laptop out the window if i cant figure this out.

Agreed. Have a base tune put on your ECU so the car will run & pass emissions.
- You won't have AVCS
- You will have minimal boost, like 6 - 8 psi

Once you pass emissions, just swap in the JDM ECU with the proper tune for the engine. It only takes a few minutes to do the ECU swap

Edit:nvm, Getting 0 degrees of VVT on either side. Guessing that the reason is something other than the wire shielding being compromised. Going to have to dig a bit deeper. Wonder if crank sensors failed or AVCS solenoids both failed. Between the fluttering AFR, the not stable idle RPM and 0 degrees of AVCS Id say I have some work cut out. Going to start with IACV gasket then keep digging. Its almost time for plugs and a timing belt anyway.

My most recent UOA. A lot better than my last analysis.

02 WRX S204 swap

Default

So about 2 months ago I was lucky enough to find an S204 Motor on Ebay. I bought it since I had killed my 205 and needed a replacement.

I am extremely happy with this motor. I elected to tune it myself and have been running E85. I finally got to put it on a Dyno this past weekend and was able to make 350 Torque and 350 Hp.

https://i.imgur.com/o8vFrLu.jpg

So Im wondering if any of you other guys with an S204 would be willing to compare some logs. I was able to get 25 psi briefly from the turbo but it looks like it likes to run 20 down to about 16 with a steady airflow of about 245 g/s once its spooled. Im still looking at a couple different ways to control it. Right now Im trying a solid 80% waste gate from about 4k-6k rpm, but boost still seems to trace the same way.

I am still on stock injectors and probably will be going flex fuel next spring , Good to see what E85 can do.

I don't think I am going to spin mine much over 22psi or so as its just hot air at that point

Ive got ID1ks and have seen about 70% as the max idc. This is also with a catted 3" downpipe (a tomioka with a vp cat welded in) and a catback.

How do you know it will be hot air over 22 psi?

Spinning a small turbo that hard , Look at the VF turbos compressor maps you get way off the efficiency chart doing that.

I too have a Tomioka catless with a full exhaust

Thanks!

heres a hypothesis im going to try to test:
The VF42 can run 270g/s and 25 psi.


Consider that map against the info in this thread.
https://forums.nasioc.com/forums/sho....php?t=1141476

The thread claims 425cfm at 18 psi for the VF24. On the graph's axis thats about 12 m3/min and a 2.25 pressure ratio. So that 425 in the turbo list is an over estimate. The TD04 is also over estimated. So Im going to assume that everything in the list is a little over the top.

It says the VF42 is like a VF22 with better spool up and top end due to it being a twin scroll. The VF22 is listed at 490cfm, which is close to 300g/s (incidently also the air flow limit in the 16 bit ecu). And, 18 psi. The VF42 comes with a stock target of 20.

On my TD04 I was never able to push it past about 21 PSI, and not for long. I could get 216 g/s out of it but it got HOT So I ended up limiting it to 200. I also noticed that the difference in flow and HP between 18 and 20 psi wasnt much.

So with all that said I want to believe the VF42 could run 25psi (it was running 22 for me no problem today) and maybe even out to something like 270g/s / 460CFM.

Adding onto this. Fuel cut for the V9 EJ207 is just under 25 psi. The TD04's fuel cut was just under 18 psi. This is not a statement to try to compare the two turbos but to try to establish a theme in Subaru's Control strategy. Knowing TD04's fuel cut and what it can do, can you figure out what the VF42 can do knowing its fuel cut?

iirc 21psi is stock on the S204 rom , I would take a look at it if you have not yet as its pretty aggressive.

I don't think the car made only 320ps , I think it was more and under rated.

Yes. Everything Ive done is based off of the stock rom. I am still using stock timing. If you compare to a standard V9 the s204 ignition timing is actually lower in several places. I spent some of my dyno time confirming that the stock timing would not be too much.

Even though the stock boost targets are 20, the max wastegate duty cycle didnt seem to be enough to reach them, atleast not in my case, It took me ALOT more wastegate to get there.


I THINK This was using the stock wgdc settings https://i.imgur.com/V3sPNQU.jpg

This is the stock boost target and Max wastegate
https://i.imgur.com/KCjatAH.png

Searching some more I ran across this
http://ken-gilbert.com/wrx/vf22compmap.jpg

So airflow of 250g/s (12.6) is definitely doable 260(12.85) is possible and 270(13.2) may not be achievable.

Boost I still want to target 25 peak.
