So these ones I have are all good for this?

Has anyone managed to spot any difference between revision C and D boards? The second largest chip might have a different serial, but it's unreadable on the board I have, other than that they seem to be equal.
Maybe someone have tried to cross flash AWD<->FWD ROMs or rev C <-> rev D ROMs?
Cross-flashing might cook the ECU, but if it doesn't, settling on latest '99 GSX ROM for all tuning needs would be great, that way we could concentrate our research on one ROM only.
As far as I understand from "Evo ECU in DSM" thread all Evo ROMs/boards are compatible.

This is really something that should be done. Right from the get go, make it as easy for yourself and everyone else by using as few ROMs as possible. The Evo guys are just now starting to try this after who knows how many years and 7 or 8 different ROMs that always need to be patched for new updates.
I was under the impression that Eclipse != JDM. The EDM and South American DSMs were the only ones to head outside of the continent new AFAIK.
Adding a Flash Connector to a 95-97:You must be logged in to view this image or video.You must be logged in to view this image or video.
On 95-97s you must add a pin at position 78 of your ECU Harness.
This must be connected to the 2.5mm phono plug on your OpenPort 2.0 cable.
It must be connected to the tip of your phono plug.
I thought pin 78 was the knock sensor. My notes, forgot where I got them from, say its pin 79 that's the flashport pin.
Ceddy,
Did you get a chance to look over the em2056.bin?
It wouldnt let me upload the rom to dsmtuners
I can send it out to others if they want to compare it to EM2055, etc...

EcuFlash ChangeLog said:2009-06-27: Version 1.42 released
EcuFlash Related ChangesJ2534 DLL Related Changes
- support for flashing H8/539FA processor (e.g. Evo 6.5) via new H8539FA memory model
- add many generic memory models to allow support for arbitrary ROMs from ECUs that EcuFlash has no flashing support for. these are named Generic1K, Generic2K, ... up to Generic2048K, including all powers of 2, plus many other common sizes.
- fix programming voltage warning errors in Subaru HC16 kernels
- actively pull up OBD pin 9 when communicating with HC16 Subarus to avoid reflash mode initialization problems on some EDM models
- add some retries to kernel reads, instead of failing
- allow unique ID data in Subaru CAN ROM protected area to be different without requiring this area to be reflashed (which is not allowed). this allows ROMs of the same version to be shared amongst users without refusal-to-flash errors.
- fixed error that limited data type to 4 bytes in size (doubles and bloblists can be bigger)
- fixed bug in Subaru K-line reflashing that did not initialize the parity mode of the vehicle interface, causing errors if the interface had previously been used with odd or even parity
Firmware Related Changes
- (no changes other than new firmware payload)
- fix bug which can cause CAN receive buffer overruns during large ISO15765 transfers
- fix bug where resting voltage of adjustable power supply can be low enough to trigger undervoltage protection of voltage multiplexer IC
- increase maximum allowable ISO9141 baud rate to be 125000 baud
Is your car smooth @ 2500-3000 RPMs, clutch in, or does it vibrate? Which pins did you swapped?OK, put my 98 ECU in today. I swapped the coil and injector pins at the harness, and added the flashpin too. I had one isolated incidence of the dreaded low load/rpm knock in the 20+ range, but only for a second and only once.

One thing I noticed though, I did an ecu read using the 96-99 EVO selection since it was the closest thing to our cars, and the load and rpm values on the axis were all gibberish. I'm very new to this software and type of thing in general, so any help is appreciated.
Oh, and for those people who need a pin for the flashport, and don't have automatics, the cruise control computer is above the passenger's side kick panel. The module uses the same pins as the ecu does, and I found that there are two suitable pins for removal, one is red w/black stripe and the other is red w/blue stripe I believe. Their positions are 10 and 11 if I recall, and they're only used for automatics, but the wires are still there on manual cars.
Is your car smooth @ 2500-3000 RPMs, clutch in, or does it vibrate? Which pins did you swapped?
I swapped pins 1, 2, 14, and 15 for the injectors per RRE's CAS swap tutorial. For the coils I swapped pins 10 and 23.
If someone wants to see axes with other ROMs you can try to adjust the axis addresses like so:
Target ROM Reference Offset
20560010 = 20550011 +0x920
23640004 = 20550011 -0x8A0
The 23640004 will most likely go wrong somewhere, but it might work. You can use calculator in scientific mode to get the new addresses by subtracting or adding to ones from the 20550011 definition.
