For what it's worth..
The ebay cable is great for datalogging and looking at things like your ECU ID and are great for people who like to know what their car is doing, but have no intention of tuning you only need the zomg expensive cable to reflash the ecu |

So, if we put aside the ECU for a second, is there anything mechanically that could be causing my odd starting problem?

Speaking of V9 ecus, I was cruising ebay and came across two V9's being sold as V8's...
They were definitely V9's as you could see the lengthened downpipes and the V9 TMICs, they weren't Spec C's. The tranny codes were V9 as well. My guess is they are having a very hard time selling V9s as the older V8 and V7 are probably not as common and their condition is degrading. I would encourage everyone who is looking to buy that you do your due diligence and make sure you know what to look for, you don't want to get an immobilized car without all the parts needed to make it run. Though I guess on the bright side all you'd really need would be the earlier ECU. |

yeah its the point were the ecu's out there which are v7 and v8 are becoming more rare. next time i find one on the fs i am buyint it for my own good just incase. knock on wood.
as far as nps settings for 1/0 if you get your rom inverted for the nps like i did its opposite because of various transmisisons and engine mismatching. i have a v8 engine but using a 05 5mt trans which had opposite nps output. make sure if your avcs is malfunctioning the iat sensor on the bottom of the mani is unplugged. your nps sensor is correct for the given trans. and the car is out of rough correction mode and up to temp before expecting it to log anything more than 1 or 2* of adv. |

I might add a somewhat obvious condition to seeing your avcs working.....the car must be moving. This had me stumped for quite some time.

Which USDM year models have the same outer timing belt covers, as the v8 EJ207? The one I'm looking at has a small hole on the passenger side.

Someone who can re-flash can just head over to the romraider database and get a 2005 STi ROM and re-flash and be good to go right? Shouldn't really matter what ECU they have as long as it has the right pinout? (and isn't immobilized, of course.) I mean, you don't really want to use any JDM ROM as-is anyway due to fuel quality differences, you're going to need to re-tune anyway. Isn't all you're really after is a starting point on startup, cold start, etc... with the right sensor scalings? Am I oversimplifying? Last edited by Concillian; 09-05-2012 at 03:57 PM. |

Well of course I don't want to run the stock WRX (MY04) ECU as it doesn't support the AVCS. I already did the AVCS wiring addition, and I'm not interested in running the V7 without it. So, as of now the car runs and drives with the V7 JDM STI ECU, but it doesn't shift properly at all in 3rd and Drive.
The only code I get coming up is the AT Temp light blinking immediately on start up, which tells me that sensor isn't being read properly with the JDM V7 ECU in. The transmission feels like the TC is slipping but it's very weird since it's feels this way even at low RPM. It also feels like maybe the pump is producing enough pressure. I was supposed to get it tuned Saturday which I thought would smooth out shifting, but my tuner figures that the V7 STI ECU probably doesn't have tables to support the AT. He also figures that the reason the transmission isn't shifting right it due to that. If the ECU can't communicate properly with the TCU it wont retard the timing in order for the transmission to shift smoothly at the shift points the TCU is sending. Other than that it pulls good in 1st and 2nd though, makes me totally want to make this happen. So, is my only option a JDM WRX AVCS ECU from an AT? Or Stand Alone, or a piggy back ECU on the JDM V7 STI ECU? Anybody else have experience running the STI ECU with the 4EAT? |

Over the last 10 years a few have tried this. I dont know why. But the best bet is to get the standalone controller for the trans.

People want them to be universal, like a PC, but they're not. Also, the ROM is only a part of an ECU "operating system". |

P&L Motorsports has an 06 or 07 STI stock block upgraded turbo, cobb tuned with a IPT Performance 4EAT it runs 11.2 sec in the 1/4 mile and an even crazier 1/8 mile time that I don't recall off hand. Pretty damn good for a slush box I'd say! |

If I remember right the V7 ECU (similar to the WRX ECU from 02 anyway) had AT maps in there as well. Anyone correct me if I'm wrong. I can't remember which pin it is though on the ECU that tells the ECU if it's manual or automatic transmission connected.

I asked this same question a while back and never really got an answer. I have a Ver. 8 JDM STi swap and it was originally tuned for 91 Cali gas with a 3" catless turbo back exhaust. The exhaust system was an HKS HI-power, which is a pretty free flowing exhaust system.
The HKS system was to loud for me so I switched to an Invidia Q300 system. My tuner was concerned that it would change back pressure too much and require a re-tune. So I logged it and he told me I was still safe on the tune I have. I want my car even quiter now, so I am looking to install a Magnaflow 3" hi-flow stainless steel cat in my system. My question is will installing a cat change back pressure enough to warrant a retune since the full exhaust system has changed since the original tune was done? What would running with extra back pressure do to the tune? Tom |

im not positive but i would think it would run richer with a more choked up exhaust. aslong as your still with a 3" exhaust i dont think a retune is needed or worth it.
i changed quite a few things before i got retuned. catback,bov to bpv,perrin tmic to sti tmic,stock wg actuator with ebcs to avo actuator on wastegate pressure. it never ran worse or blew up. i did some logs and sent them to clark,eventhough my old map was crap he never said it was dangerous. it did run quite a bit better with retune but i only gained 8whp and 17tq over the old tune with the same psi. |

sometimes i think people take tunes too serious. a wideband would be a great thing to have. aslong as your not risking blowing it up a retune isnt needed and prob wont help much unless your changing something drastic.
also i would try to find a good flowing quiet exhaust. my greddy evo 2 is great. flows better than my autospeed twin tip did and its quieter! |
