THIS IS A WORK IN PROGRESS - Please PM any suggestions/corrections.

This is a Sticky for the stock EJ20G ECUs and their use on the 1991-1994 US Domestic Market (USDM) Legacy SS and TW with the stock EJ22T engine. Thread also includes info on running the Rob Tune Chipped EJ20G ECU.

DISCLAIMER: Any changes made to your car are your responsibility and at your own risk. Please do your own research!

What's REALLY Required to Run an EJ20G ECU?
- Ignition adapter
- MAF
- Injectors

- 440/450cc gray top side-feed from '92-'96 (?) JDM or UK WRX/Sti

- Turbo - not required, but recommended, as max. boost on VF11 is 12-14 psi
- Intercooler - highly recommended due higher boost levels creating more heat
- Wiring
Edit - 2 additional things I recommend:
- Boost gauge (needed to see boost level and for MBC adjustment)
- MBC / Manual boost controller - Per Rob, "I always recommend a cheap manual boost controller, or any expensive EBC to manage boost." But not the stock BCS.

(See below for more details.)

Nearly all 4-plug EJ20G ECUs will work from Imprezas or Legacys that were available from 1989 (?) - 1996 (?).

Here's a list w/ECU, Injectors, and Turbos from HERE (remember, Rob's tune overrides the stock injector size so this is just for reference):
Impreza JDM / UK EJ20 ECU info:
Classic import (saloon) <sedan> '92- '94 (wagons are called 'estate')-
(note: 440cc = gray; 480cc =yellow as noted below.)

How To: 440cc Injectors in Legacy Turbo Rails
-Thread on installing the 440's.


Note on 440cc injectors. These are the JDM/UK Side-Feed, Gray top injectors. They are commonly referred to as '380cc' in the UK. I've emailed many sellers on ebay and they use '380' more often than not. If buying these injectors, make sure you understand what you're getting. My guess is the difference is due to the use of a different pressure standard in the UK vs. what the USDM market adheres to. I've also seen JDM/UK 480cc yellow tops, listed as 440cc on the ebay UK sites.
So, UK 380cc= 440cc, and UK 440cc= 480cc.
The 440's actually flow closer to 450cc, when tested @ 43.5 psi/3BAR.
The JDM/UK 440's and 480's WILL FIT in the stock Turbo rails.

I don't know if the '02+ USDM WRX 440 top-feeds can be made to work w/the EJ22T intake.
And don't confuse the UK/JDM 480's w/the USDM STi 550's (closer to 525cc @ 3 BAR) used from '04-06, which are also side-feed yellow tops.

Why Bother?
Due to the recent interest in the 'Rob Tuned' EJ20G ECUs and their relative ease of use on our cars, I thought it was time to create a dedicated thread.

There is limited support for ECU-based upgrades on the stock EJ22T ECU, and adapting an EJ20G ECU is a viable option. The EJ20G ECUs were used on European/Australian/? and Japanese Subarus. Specifically, the Legacy and Impreza-WRX/STi. LINK for the EJ20G on Wikipedia.

Yes, you can install an MBC and FCD and up the boost on the stock EJ22T, but there won't be any tuning to take full advantage of the increased boost. And with the EJ20G ECU, you can better control bigger injectors and a bigger turbo - some of the late model EJ20G's came with 480cc injectors and a top-entry TD05.


What ECUs Will Work?
EJ20G ECUs were available from 1989 (?) - 1996 (?) and have the same 4-plug connector as used on the 1989-1994 USDM Legacy - turbo and NA use the same connector.

Here's an incomplete list (scroll down for a list of injectors/turbos associated w/these ECUs):
U8, 2C - 1993/1994 WRX - 11.47psi
W6 - 1993 WRX RA - 11.47psi
W9 - 1994 WRX RA - 11.47psi
SA (STi chipped) - Ver1 STi (Sedan and Wagon) - 14.94psi
SB (STi chipped) - Ver1 STi-RA - 13.64psi
SC (STi chipped) - SAME AS Z4 - Ver2 STi Wagon - 12.78psi
Z4 - 1995/1996 WRX - 12.78psi
Z5 - 1995/1996 WRX-RA - 12.57psi
6K - Ver2 STi Sedan - 13.34psi
7K - Ver2 STi-RA - 13.19psi
Prodrive UK ECU (Prodrive Chipped) -- SAME AS 6K - 13.34psi
1C, 3B, V9, V5 - All WRX Wagons 10psi, dropping to 6.8psi
V7, 7D, 6D - 1993 to 1996 UK/Euro 11.47psi

Nearly all 4-plug ECUs will work from Imprezas or Legacys.

Adapting an EJ20G ECU is another thread by Rob to explain the techinal differences between the EJ22T and EJ20G ECUs.


What is the benefit?
One very cool reason to install an EJ20G ECU is that most of these run more boost and will do so with this minimal list of changes, most of which are necessary to upgrade anyway. There is also more aftermarket support for these, albeit not much in the US, and there are ECUs from other companies that are a direct swap for the EJ20G ECUs.

What are the 'Gotchas'?

1. Intercoolers: All of the EJ20G Subarus used an intercooler (IC) that I've seen - I believe the USDM Legacy SS/TW were the only Subarus w/a turbo BUT no intercooler (excluding the earlier '80's GL/GL-10/XT models). The EJ20G used a top-mount IC (TMIC) or an Air-to-Water IC (AWIC).


2. Octane: I'm sketchy on the details of the exact comparison, but Japanese gas is reportedly much better than USA's. A Japenese-spec ECU may not work well even on US Premium/Super Unleaded.

The UK-spec ECUs are tuned for Premium that is very similar to 93 Octane that we can get. It's possible that certain EJ20G ECUs are tuned for a specific higher octane...still searching on that possibility.

I don't know what kind of 'petrol' the Aussie's have, so don't know what their ECUs are tuned for.


3. Cold (-blooded) Start tuning: Rumor has it, and my personal experience w/two different EJ20G ECUs confirms, that the EJ20Gs are cold-blooded. When the temps are below 50 it usually starts and stops, and then fires up normally on the 2nd try. I've not run (ran?) the EJ20G ECU thru a winter yet, so can't comment.
Once started/warmed-up it runs fine and restarts normally.
EDIT: After I replaced pistons (low Comp on #2 - broken ringland), my car started fine....so in my case it was an engine issue - not ECU issue.

What If I Still Want More?

If the owner has the proper tuning tools, such as a wideband for Air-Fuel Ratios (AFRs), and a knock-lite, a Fuel-Cut Defender (FCD) could be installed to override the stock fuel-cut and allow increased boost to better utilize a bigger turbo.

Custom Tunes for the EJ20G ECU

EJ20G "RobTune" Info - Info on getting a custom tune for the EJ20G ECUs. Please NOTE that only certain EJ20G ECUs can be tuned - reference the thread for specifics.

Other EJ20G ECU compatible options:
SUBARU APEXI POWER FC and Commander - Replaces the EJ20G ECU and w/the commander is user-tunable.


What's REALLY Required to Run an EJ20G ECU?
- Ignition adapter
- MAF
- Injectors
- Turbo
- Intercooler
- Wiring
Edit - 2 additional things I recommend:
- Boost gauge (needed to see boost level and for MBC adjustment)
- MBC / Manual boost control - Rob doesn't recommend using the stock BCS (boost control solenoid) or other EBCS (Electronic BCS) to manage boost.

Ignition adapter

The EJ20G used a Coil on Plug (CoP) arrangement. This means there is no central coil pack as on the USDM Legacy, but an individual coil @ each spark plug. There are also 2 additional wires in the harness that run to the ECU connector for the EJ20G's ignition system. The EJ20 has a double-igniter/ignitor for the extra 2 channels, too.

NO - you DO NOT need to start looking for CoPs - the existing system can be used with a bit of adaption.....keep on reading.

Check out Rob's 4to2 Igntion Converter that will simplify this task by installing a converter in the EJ22T's system that will work w/the EJ20G ECU.

MAF

- JECS MAF - (From any NA (non-turbo) Subaru that used a JECS or AUTECS Green Label MAF from '90 - '99 )


Injectors
- 440cc or 480cc Injectors* (see below) - These fit the '91-94 turbo fuel rails. If using DOHC heads (EJ20 or EJ25D) you'll need the EJ20 fuel rails for both the EJ20 and EJ25D intake manifolds.

If using the the Rob Tuned EJ20G ECU:
- 550/525cc yellow side-feed injectors from '04-06 STi/OB XT/Forester XT/Legacy GT/Baja Turbo- These fit the '92+ NA SOHC rails or use the EJ25D rails w/the DOHC heads/intake.

*Note on 440cc injectors. These are the JDM/UK Side-Feed, Gray top injectors. They are commonly referred to as '380cc' in the UK. I've emailed many sellers on ebay and they use '380' more often than not. If buying these injectors, make sure you understand what you're getting. My guess is the difference is due to the use of a different pressure standard in the UK vs. what the USDM market adheres to. I've also seen JDM/UK 480cc yellow tops, listed as 440cc on the ebay UK sites.
The 440's actually flow closer to 450cc, when tested @ 43.5 psi/3BAR.
The JDM 440's and 480's WILL FIT in the stock Turbo rails.

Here's a way to view the EJ20's different version injectors and their rates with pressure:
From NASIOC:
..............................pressure (Bar) 2.55 3.05 3.55

GC8 VerⅠ、Ⅱ ej20G,ej20h (89-9/97) 440ｃ 480cc 520ｃｃ

GC8　VerⅢ、Ⅳ ej20k,ej20R (9/97-9/99) 480cc 520cc 550ｃｃ

GC8　Ver Ⅴ,VI ej205,ej207 (9/99-9/01) 490ｃｃ 530cc 560ｃｃ

HERE is a thread on installing the 440's.
I don't know if the '02+ USDM WRX 440 top-feeds can be made to work w/the EJ22T intake.
And don't confuse the UK/JDM 480's w/the USDM STi 550's (closer to 525cc @ 3 BAR) used from '04-06, which are also side-feed yellow tops.

Turbo

The stock EJ22T's VF11 would work w/any of the ECU's that don't exceed 12-14 Psi, as that's the limit of the VF11. But it'll also likely shorten the life of the VF11 as it will be working very hard @ those levels. Plus, it defeats a big reason for upgrading to an EJ20G ECU anyway - More Power!

Recommended:
- TD04 or TD05/VF39
There were a variety of turbos used - many VF-series models (btw, the # doesn't specify a size. The #'s increment w/each successive model.)
A great list of turbos is HERE on NASIOC.

The USDM WRX TD04 is easy and cheap to get, and is a small upgrade over the VF11. The VF39 from the USDM STi is major upgrade and is very similar to the TD05-16G that was used on the EJ20G cars.

Here's a list of models w/ECU, Injectors, and Turbos:
Impreza JDM / UK EJ20 ECU info:
Classic import (saloon) <sedan> (wagons are called 'estate')- 92- 94

(note: 440cc = gray; 480cc =yellow as noted above.)

2C ECU code = 440cc injectors, 240ps TD05H turbo

W6 ECU code = 440cc injectors, 240ps TD05H turbo

U8 ECU code = 440cc injectors, 240ps TD05H turbo

SA ECU code = 440cc injectors 250ps TD05H turbo

SB ECU code = 440cc injectors 250ps TD05H turbo

Classic import- (saloon) 95-96

Z4 ECU code = 440cc injectors, 260ps TD05H turbo

Classic import- (saloon) 97-98

IS ECU code = 480cc injectors, 280ps VF22 turbo

6S ECU code = 480cc injectors, 300ps VF23 turbo

75 ECU code = 480cc injectors, 280ps VF24 turbo

A7 ECU code = 480cc injectors, 280ps VF22

J2 ECU code = 480cc injectors, 280ps VF28/VF29


Intercooler
As stated above, the EJ20G used a top-mount IC (TMIC) or an Air-to-Water IC (AWIC). The best-fitting TMIC for the Legacy EJ22T is the '06-07 WRX and '07-08 Forester TMIC, and there are PLENTY of threads on here about fitting one.

A front-mount IC (FMIC) is also doable, but a heck of a lot more work as there is no (known to me) plug-n-play option.

There are a still a few of the AWICs floating around and they will work, too. They also require a bunch more work to install vs. a TMIC, due to their pumps/radiator/etc. Search this site for more info.

The hood scoop on the stock SS/TW is small. Does it inhibit flow? Probably. Search on here for installing a custom scoop or making a WRX fit.

Wiring
The ignition differences are described above, but the MAP sensor also needs addressed. Otherwise, it'll throw a code - 45. The solution is to remove pin 5 on B48 and join it with pin 21 on B48 @ the ECU connector.

Boost Gauge
Any boost gauge that reads up to 20 PSI should suffice. I'd ensure it also reads Vacuum - down to -20 as well. This can help w/engine health issues. Search on here for the best source for the vacuum line.

Manual Boost Controller (MBC)
The EJ20G tune works best w/an MBC, set to whatever you and Rob decide is best for your setup. You CAN use the stock BCS as the WRX/STi came w/the same or similar BCS as the Legacy, but the car runs better and is More Fun w/the MBC. (One caveat to an MBC w/an Automatic transmision: If you're driving on slippery surfaces and climbing a hill, boost comes on strong if you kick down and may also kick-out your car's rear end - be ready!) Basic is all you need, as I used one of these off Ebay for years w/out issue:

ECU Diagnostics
The ECU can diagnose any fault that may arise due to abnormal signals that are sent to the controller. The ECU Check Engine will illuminate in the instrument console if there is a problem with any of the computers inputs. It is possible to find which sensor(s) is faulty by following these steps:
Turn ignition OFF
Connect read memory connectors
(jumper 5) [black connectors]
Turn ignition ON (Engine OFF)
Engine Check lamp turns on
Code is indicated by Pulsing lamp
If Code is OK then Turn ignition OFF & Disconnect Connectors
Check ECU Code
Turn ignition OFF & Disconnect Connectors
If there is a fault Check Appropriate Sensor

Back to top

ECU Reset
On early MYs (especially pre MY97) the ECU retards the ignition when knock is detected, however, it is very slow to advance the timing again. An ECU reset will restore the car to factory default settings. This will remove any stored fault codes and restore ignition advance. It is possible to reset the ECU by following these steps:
Turn ignition OFF
Connect Read Memory Connectors & Test Mode Connectors
(jumper 5) [black connectors] – (jumper 6) [green connectors]
Turn ignition ON (engine off)
Engine Check lamp turns on
Depress accelerator pedal completely
Then return it to the half-throttle position and hold it there for two seconds
Release pedal completely
Start engine
Code is indicated by Pulsing lamp
If a fault is detected - Check ECU Code
If no fault is detected - drive the car sensible for a couple of minutes
i.e. until warm (do not run tall & do not thrash it!)
When the ECU has been reset the Check Engine Light will flash
Code is indicated by Pulsing lamp
If a fault is detected Check ECU Code
Turn ignition OFF & Disconnect Connectors
If there is a fault Check Appropriate Sensor

Back to top

Finding Those Connectors
As said above, in order to perform diagnostic & ECU resets you need to find the Black Read Memory Connectors & the Green Test mode Connectors (alternatively there is the dash option shown above but this is even more tricky). The connectors are located under the dash up by the steering column. If they have not been used before they are usually taped quite high up & can be difficult to find, but they are there, once untaped they dangle down and are quite easy to use. Here is a poor photograph of the Black Read Memory Connectors & Green Test Mode Connectors on my Scooby.

Back to top

Reading ECU Codes
The ECU codes are displayed as pulses of the Check Engine Light.
If Check Engine Light goes out there is no fault.

In Diagnostic Mode – No Fault is indicated by the Check Engine Light continuously & evenly flashing on/off (this is also used to indicate the successful completion of an ECU Reset).
The long pulses (1.3 Seconds) indicate Tens and the short pulses (0.2 Seconds) indicate ones. Pulses are separated by Short Pauses (0.2 Seconds), multiple codes are separated by a Long Pause (1.8 Seconds).
The simplest way for an inexperienced mechanic to retrieve codes is to write the codes down in a sort of Morse Code (dots and dashes), and start a new line when you get a 1.8 Second pause (for NEW code), and
then add the actual numbers up after code retrieval is completed.
(See Example Below)
--- CODE EXAMPLE, SINGLE CODE ---

1.3 second pulse (10)
0.2 second pause
1.3 second pulse (10....for a total of 20)
0.2 second pause
0.2 second pulse (1.....for a total of 21)
0.2 second pause
0.2 second pulse (1.....for a total of 22)
0.2 second pause

0.2 second pause
0.2 second pulse (1.....for a total of 21)
0.2 second pause
0.2 second pulse (1.....for a total of 22)
0.2 second pause
0.2 second pulse (1.....for a total of 23)


1.8 second pause (this means NEW code)


1.3 second pulse (10)
0.2 second pause

Nice work Todd! Hadn't commented before but I figure you deserve mad props for this.

Thanks.....glad @ least 2 people read it.

Ok..it's had 999 Views as of today......maybe a couple others.

TD

This guy is awesome. I own his old legacy, and he has been extremely helpful to me. He definately put in alot of time learning all this stuff.

Thanks Eric!

Great thread wtdash! It answered a couple questions I was having.

Now I just need to hear back from rob about buying the ignition adapter and this ECU and I'll be set to go.
