Tephra for 3-plug ECU
I have a USDM 3-plug ecu (05 Evo8) rom id# 96940011. I'd like to flash it with a Tephra rom to take advantage of the extra features, but I'm not sure which Tephra version is best suited for this ecu?
Also, I want wire a clutch switch to activate both launch control & flat foot shifting, to what pin do I need to wire the switch to?
Thanks

Do you know the clutch switch pin number for a 3 plug ecu?

Anyways,
Check this link out. The file is double zipped...so add a '.zip' extension to the file within the archive and extract again.

EVO 8 ECU pinouts are all over the place too. Just search through google.

If you have 4 Plugs at the ECU but only 3 in the wiring loom, than its an LHD car.
But it is not the same Ecu as the USDM / EDM Evo 9´s.
The 96940011 will be right for these UK/JDM Cars RHD

As evoredy said, it's possible that somebody had flashed an older rom into a newer ecu. One thing I'm sure of is that the ecu is USDM because its harness is LHD & has three plugs.
Thank evoredy for the link

Again, please post a picture of the ECU. Cell phone snap will be fine. Motherboard will be even better.
Seems like you don't have an EVO ECU at all. MH8206F is the USDM EVO 8 chip, but it does not carry a 3 plug form factor that I know of...correct me if I'm wrong.
SO...keep using the EVO 8 ROMS (256KB) and HOPEFULLY it matches the EVO 9 pinout. You will have to test things out or get the pinout from the manual of the donor vehicle.
Seems like someone has flashed a non-evo ECU with an 8 rom and called it good!
Good luck man.

The very same chip was used in a few Lancer Ralliart Ecus also.
These have 3 Plug locations ( Each plug has 2 rows of pins per plug )
The Evo 8 USDM/EDM Ecus have 4 plug locations, BUT 2 rows of pins per plug
The Evo 9 USDM/EDM Ecus have 3 plug locations, BUT 3 rows of pins per plug
The Evo 8 JDM/UK Ecus have 3 plug locations, BUT 3 rows of pins per plug
I am not talking about the wiring loom inside the car. I refer to the possible Plugs at the ECU´s
Please make some pictures.
