what EM do you guys use? I'm scared to have any tuner tune my ecu with the change the tune will **** up the smoothness
according to PDX an AccessPort is compatible with the JDM ECU but on Cobbs website it states otherwise. Am I right to assume that the hardware is compatible rather than the maps that accompany it? What are my options? Jon

You don't have any options aside from openecu or ecutek. Cobb doesn't release their JDM AccessPorts in the states- you'd have to buy one from Japan.
Just find someone to tune it who knows what they are doing. You might be able to do a mail order flash too. |

Do you get a CEL? I have a JDM UTEC and I know it is supposed to not throw a CEL and maybe do one or two other things the USDM UTEC doesn't do.

Alright guys here is the deal, right from sema.
If we want the accessport from Cobb we need to email email email and hurass hurass hurass them. They are working with prova in releaseing one for the JDM land but they are slacking because of other projects but as long as we keep on their collective asses about it, it will come out. Trust me, every day at the show I am hurassing them about it They told me, officially its not comming out but unofficailly it will be out it just need some fire under their asses about it. |

yea, i emailed those 3 addresses and got a address not found error from yahoo so thats why i asked. i did go to their thread in the for sale forum and sent them a pm, guess i should call them as previously suggested.
since im looking at all this now, what turbo's are you 207 guys running? and how is it DD with a turbo that might not kick in till 4000-4500 RPM's? |

so why is it that Jarred from PDX showed me the ProTuner software that supports the JDM ECU when he came down here to tune?
He has tuned other cars with JDM ECU and Engine. I mean technically is the AVCS on a 2.0L engine. Hardware wise is the same since both USDM and JDM ECU for late 2001 to late 2002 JDM year have the same type of ECU with both automatic and manual mapping on them. The only thing different is the firmware. This is why Enginuity can work with the JDM ECUs. PDX seems to be the only qualified candidate that will come down here and tune my engine for a decent not overly inflated price. I mean we've even got AMS coming down for a tuning session but they want a **** load more money. I might look up Dom from GetaDomTune and see what he says (he used to live in HI) Jon PDX also tunes ECUTEK as well. Where might I find a JDM UTEC? |

Does the EJ207 have the same house housing as the EJ205? I ask because Im thinking of getting a 20G TD-06 for my EJ205 and run it until the engine finally dies then ill just get a EJ207 and swap out the VF30 for the 20G

Protuner supports the ECU but you need an accessport that will may itself to the ecu first. You will not be able to find a v7 jdm accessport. The way to flash the ecus is similar but you'd need an accessport which has a v7 'mapping' if you will. You can't load STi maps on a WRX accessport, just like you can't load JDM maps on a USDM accessport. So yes, Protuner will do it, but you'd need the appropriate accessport first.

I guess technically any accessport that doesn't have maps for a USDM car will work then as long as someone will be able to protune maps for it then? I need confirmation before I spend money

I have a few ?s on the EJ207. Can I run 93 octane in this engine?, Will the 207 have the same uppipe as the 205?, and if I buy say a 20G for my 205 will it bolt up fine to the 207?

well about the fuel issue. 93 is the highest octane they offer where I live so if I get a retune on the 207 can i run it?

you need to get a tune to run 93. that's it. then the motor will be fine. you could take your chances and run the stock tune, but i wouldn't do it.....

well if i had to guess, the ej207 and all japanese wrx/sti/etc's are all spec'ed to run 101oct in japan. 101 is the std "performance car" gas grade over there. kinda like 91 is tops recommended over here.
(i know what i'm about to say is not new, but occasionally people need to be reminded...) But! 101 over there isn't 101 over here. 101 RON (japanese method) is equivilant to our 94-95oct ((MON+RON)/2, US method). running good 93oct in your car isn't far off from the right gas. It's not like you're running total swill by downgrading 1-2 points. Worth re-tuning your car to run 93 with an ecu expecting 94...? In fact at higher altitudes in the US stations stock 85 as regular instead of 87, since its been proven to work fine. I have ran 91oct chevron in all of my japanese motors(or ecu setups), and never had a problem at all. Just for reference to the thread, that includes my current v5 ej207. Plus, if you're not running on the ragged edge of a hard tune or something (just stock ecu for instance), then your ecu will react just fine if it detects knock (we have knock sensors), and make sure the motor runs ok. Bottom line. Your motor will run fine on US gas. Now, tuning for more power? Thats always a different a story... Thats when things break, when you push them past stock reliability/power levels. Nothing new there. Last edited by neko; 11-05-2007 at 11:18 AM. |

I'd suppose you might be able to run an AP on an EJ207 if you ran a USDM ECU. In order to pass emissions I just had my ver8 207 Ecuflash map reformatted and reflashed onto my old 02 WRX Ecutek ECU. Motor seems fine, definately down on power without the AVCS and running rich for sure without the timing advance but it is an option for those of you who might already have EM.
I've lost a lot of throttle response but I'll be swapping in this ECU once a year to pass emissions and then go back to the normal JDM ECU. |
