I'd really like to know where my ecu came from. obviously my clip but i've never heard anyone have the same specs as mine. out of a V2 STi 555 Edition

Rev Limit - 7250
Max Boost - 1 bar
Fuel Cut - never taken it there
Speed Limit - not sure either but the concenus on JDM limiter is 113 i think.

rob · 04-10-2007, 11:36 PM

What's the 2 digit code on the ECU?

GripGC8 · 04-10-2007, 11:38 PM

thanks again rob

hail2theTheif · 04-10-2007, 11:41 PM

cool. My guess is that it's the same as the ver2 STi ECU which was 6k. If so, I have the details for that ECU as well.

<--rocking the 6k ecu, so more info would be greatly appreciated

rob · 04-18-2007, 04:52 PM

The only difference I see is in the boost targets. They are a tick higher for the 6k. Even the fuel and ignition maps look the same with the Z4.

Rev limit -- 7100 RPM
Max target boost -- 0.94 bar (13.6psi)
Fuel cut -- 1.08 bar (15.7psi)
Speed Limit -- 113 MPH

Sounds like the scoobyecu chip. Raises boost to 1.1 bar. On my 555 ecu it can get 1 bar but only b/c of the bigger turbo and free flowing exhaust.

What's the the 2digit code on your 555 ECU?

hail2theTheif · 04-19-2007, 01:54 AM

wierd i posted the other day responding but it didn't show up. how do you get the cover plate off? haha. i can see 3 screws but i have a feeling there are more than that. anyone?

kingsubi · 04-19-2007, 02:16 AM

Are you sure about that rev limit? On Kbahus's 6K ECU I know he took it to 7500 a few times without hitting the limiter. Moose told him it was 7800-8000 when he sold it to him...

Not 100% sure. I only have a portion of the ECU dump for the 6k. It's possible that it's mixed up with some other code (although I would be suprised). I have the full code of the 7k (STi-RA ver 2) and the rev limit shows 7700. Perhaps Kbahus's ecu is chipped?

-Rob

Matt Monson · 04-19-2007, 06:12 PM

If it is chipped that would explain a lot. I never pulled the cover on it to see if it was chipped and I don't have it anymore. And before you say anything, I know you wanted it, but a local offered me silly money for it along with a stripped Ej20G harness ready for swapping. I just couldn't pass it up...

7700 sounds like mine.

And I just picked up a scoobyecu for ~$100 to safely get up to 1.1bar and use regular pump gas. Although at $4.99/gal for 100, its not looking that much more based on the prices for 91 out here.

Marnix · 04-20-2007, 02:42 AM

AFAIK the STI ECUs rev higher than the stock WRX; the EUDM EJ20K ECU (MY97) allows 7200 rpm, 0.87 bar (fuel cut 1.08 bar) without speed limit - typically with long WRX gearing these do 6k in fifth at about 240-250 kph on the speedo.

hail2theTheif · 04-20-2007, 03:26 AM

where did you find the scoobyecu kingsubi? rare find or relativly easy to find? I would like to upgrade mine to get some more power outta my car but the PFC are gettin harder and harder to find for our cars and I have no idea how to tune it.

kingsubi · 04-20-2007, 01:39 PM

check out this seller on ebay: rick9761

http://cgi.ebay.com/ws/eBayISAPI.dll...m=290106380853

some go for more, some less. Seems like he is making them by coping the scoobyecu map onto new chips. Either way I should get it in a week or so and update the differences.

kingsubi · 04-23-2007, 11:29 PM

edit: mine is a 6K sti ver2 555 edition

civic2scooby · 04-24-2007, 12:50 AM

specs for the W6 ecu?

hail2theTheif · 04-24-2007, 01:24 AM

would love to hear the results when you get it. i hope he will have more for sale if it works out. at the moment he has none listed.
