thank you. i was hoping i could keep all the internal bits the same and just use the sensors wiring and ecu but i guess i need to change cams. which im unable to do.

You need to change only the intake cams with USDM EJ255/257 units. And do just a little (and I mean little, it took me 20 minutes) bit of grinding, machining to move the cam position sensor slightly to read the cam properly. Then it works fine. Swapping cams is very easy and the FSM can walk you right through it.

Amroof, lukeskywrx, and I will be possibly making a more in-depth thread on this with 100% of the details and pictures one of these days.

Re-check all your wiring.
I just re-checked all the pins for avcs on supplied ia performance wiring from the ecu harness to the cam sensors and solenoids. all wiring checks out fine. pins are mapped properly for shielded and un shielded wiring based on supplied info on ia performance kit. for testing the wiring i used my multimeter and tested for continuity.

resistance for avcs solenoids is driver side 9ohms, passenger side 13 ohms

I have not swapped them yet. I did clear codes, unplugged avcs solenoid wiring driver side. just p0390 no change in behavior. i cleared codes and plugged in driver side avcs solenoid and than unplugged passenger side. still p0390 error, cel only comes on at idle, goes out when above that.

tuner used base map for a v7 sti w. open ecu a4sda01b

One thing that stands out is this in the ia performance troubleshooting section.

3) For some ECU's it is necessary to cut the factory wire location at #1 Plug E and ground ecu end to chassis. We have found the 580 ecu's require this. It is recommended to install the wiring kit and test to see if avcs is working during a test drive. if it is not then grounding the ecu at this pin ma help remedy your problem. we don't guarantee it though...

my ecu is: 22611ah581

I don't just want to just go and cut wires...

i ran across this thread which has me scratching my head.

Clark you make me laugh!
This statement kinda contradicts your self

"It's not a 207? But it has a v9 engine in it?"
Does that mean its not a 207? Its a mystical creature from another world?

And op your car will be a blast to drive if you go 207. I would recommend a V8-V9 engine over a V7.

not sure what to do next.
common things to look for are NPS signal, make sure it a "1" when in gear.
If you are troubleshooting via the IAP or DS1 instructions, pin orientation can be confusing from the view of the plug. It messes up alot of people.
Someone just recently posted about which specific pins they swapped recently while troubleshooting and got their avcs working.

Good point Dan. Alot of people get the wiring backwards as they look at the plug wrong. Another thing that is important is to make sure the rom file matches the ecu and engine. Kids with tactrix cables will throw any rom they can get for free on the ecu and not all will run the cams even though the car runs and starts. I documented the Diode/resistor/pin differences on the boards. That list of roms must match the ecu. Or avcs wont ever work... Very common mistake people make. I fixed one the other day as the guy had the wrong V8 file.

well than two of us are reading the instructions wrong. my brother originally pinned it. i just verified his work. pins can be confusing but directions do say when looking from wiring side vs. pin side. some connectors couldn't have wiring go to incorrect spots due to wires existing. i'm sure the wiring is correct (well matches ia performance instructions, as well as all wires checking out via voltmeter)

i also tried e1 pin 1 to chassis as ground. still same symptom. so either ecu is bad, wiring diagrams supplied by ia perf. is wrong, or solenoids are crap.

If one solenoid was bad would avcs work on the remaining side? contacting ia perf. now to get resistance on a new solenoid for comparison.

i suppose i can start looking at other sources for pin locations to ensure there isn't something wrong there.

very possible, its still not working, right? Or could be wired fine, but other criteria haven't been met. Like i mentioned, NPS signal, etc...

is there some info my tuner can get me to ensure i have the correct rom? I asked him to double check he used one for a v7 sti. I leave the tuning to others as I wouldn't know how to tune my own car. The local tuner is from our mnsubaru forum and has tuned quite a few cars and comes highly recommended.

My ECU is 22611aha581 ,, the tuner said he used a4sda01b for my ecu (open ecu i believe).

one thing i didn't understand is that when i unplugged the passenger side avcs solenoid. I didn't get a different error other than p0390 unless i didn't run car enough for it to register. p0390 is bank2 (driver side from what i understand) i would have expected a bank 1 if i unplugged the passenger avcs solenoid.

I should re-mention that the p0390 didn't always pop up on this car. After the initial swap there were no cel's for 4000 miles. whether or not avcs was actually functioning i can't say as i didn't see the maps on the initial tune.

Can you explain the NPS signal quickly? ahhhh neutral position sensor. Could a NPS sensor go bad and disable avcs? I assume checking this has to be done with my tuner to ensure it is 1 when in gear.

i will cross check pins on the ia perf. sheet provided with those on the boards. I'm confident I was looking at the pins correct, verified now. instructions are clear with actual photos showing what you should be looking at and what side pin is on as well as the schematic.

apart from an ecu issue the only thing not replace is the solenoids. I'll wait to hear back from ia perf. on the best way to verify they are working.

thanks for all the help, i appreciate it. I neglected to say so earlier.

interesting as avcs isn't working on either side. i suppose i could have 2 bad solenoids , leaning towards something tune related (if not something in wiring i cannot see)

per IA Performance and my experiance on my v7 engine / v8 6spd:

2) Cars running a USDM 2005+ transmission will need to swap their Neutral Safety Switch (NSS). Problems that arise in these cases: Car shows no CEL, but AVCS is not working. Data logging the NSS it should show 1 in neutral and 0 in gear. If this shows the opposite then you need to remedy this. We’ve been told previous year USDM NSS will work, cost is roughly $40 at the dealer.

Bet you the NPS is wrong. The 581 ECU is going to look for an inverted NPS which came on the V8 cars and 05+ USDM STI. The 02 WRX and V7 JDM cars have a non-inverted NPS.

AVCS is inactive when the car is in neutral, with the wrong NPS the car will think it is in neutral when it is in gear resulting in no AVCS. You can swap the NPS with an inverted one from a later model USDM STI and it should take care of you. Think they run about 50$ at the dealer.

It is tempting to recode the 581 rom to add a selection for the NPS since so many people have this issue, the carberry SD rom has this feature so you just select inverted or normal NPS. Carberry rom works great on the 581 by the way, ditch the MAF and don't look back.

the car is an 02 wrx, with the v7 and 6spd jdm transmission (should be matching v7 engine/trans, they came together.). so I would be looking to get an inverted NPS out of later model sti?

a followup: if the ecu/motor/transmission are all jdm why does the 581 need a different neutral position sensor (non-inverted to inverted)? is it because the 581 jdm ecu is different than other jdm ecu's?

581 is from a JDM v8 so it is looking for the inverted NPS that came on the v8, it does not match the rest of your swap. It is just the gradual changes that happen version to version.

V7 normal NPS
V8+ inverted NPS

Also what color are your coil packs? If they are black the 581 ECU has the wrong ignition dwell time and you could burn out your coils. Most v7 motors are the black coil packs so you will likely have to change your dwell settings.

i was just going to come and post the ecu was a replacement as the one that came with the v7 sti engine/transmission was bad (before i got the car). A replacement was sent. I was under the impression that I had a v7 ecu and that is what was sent. This clarifies a lot.

So helpful these forums are.

So since the assumption was it was a v7 ecu. i probably have the wrong base tune on the ecu that is messing this up (along with NPS). I'm pretty sure the coil packs are black as well. Is there a way to change the (ignition dwell) to prevent the coils from burning.?

I'll be getting the inverted NPS. Looks like the ia Perf. wiring kit is for v 7/8/9 for avcs so i think I should be ok there.

thank you, thank you

Here are the definitions to change the ignition dwell http://www.romraider.com/forum/viewt...55bf00b7b2f055

Just pull the correct values from a v7 rom or an 02WRX rom

didnt read everything but the pin orientation needs to be on the right side of the plug. switching with newer nps sensors requires cutting the sensors off and soldering your old plug on so it goes onto your current harness. the new harness's and old harness plugs are different.

My tuner says he is able to account for the NPS via rom. I am having him re-tune it today. He also corrected the dwell settings. He stated since the rom that was on my car was for 01-02 which uses black coil pack dwells there was no risk of damage. He has it corrected for the 581. Thanks again lukeskywrx

and to finally contribute at-least a little something:
v7 jdm avcs solenoid resistance at the pins is 7.5 ohms
ia Performance measured this on some new ones yesterday.

Another question- are you guys getting these fabulous deals by calling them? If so I have a list of people to call and see if I can get a better deal than $8000 for a version 7.

@tuner,
He Loaded stock 581 rom with coilpack dwell settings for my black coils. Still p0390 when below 1200rpms.
Tried it with both inverted and inverted nps settings.

p0390 wasn't originally an issue for first 4000 miles of swap and according to tuner avcs was functional initially.

Since both rear sensors were replaced and new cam gears were installed what else can trigger p0390? Solenoids? Plugging or unplugging either side shows no change in car behavior nor any more cels.

could my replacement sensor also be bad??

If i unplug passenger side avcs sensor cel
Stays on trips p0365, bank1

If i unplug driver side the cel also stays on on p0390 only.

Plugging driver side in it cell only comes on below 1200rpm. Seems like driverside is functioning at some capacity.

Bad ecu? Problem with camshaft?

Whats wrong with having a thread to help each other trouble shoot as well? It's kinda always been that way as well from all the pages I've read.

And what's it about now, Clark? Last I checked, at least 90%of the posters here have an EJ207 and come here to talk about it.
