Subaru Impreza WRX year 1993

Hi Guys

I have got a client with a Subaru Impreza WRX GT year 1993 (Japan Spec). Has anyone here ever tuned one of this cars....? Can anyone tell me how this ECU can be done...?

Attached a picture of the ECU...

Thanks!

It can be done with a 27C1028 EEPROM or a 27C512 Board which emulates the older style 27C1028 chip.

You will need to "socket" the ecu and cut the resistor at J1 if i remember correctly.

Hi,
I have the same ecu and want to tune it!

ECU label:
U8
22611 AA810
A18-000 RJ2

It has socket and the resistor J1 is conected to switch wired in to the dashboard for the driver to be easy to switch.

Where can i buy this 27C1028 or the board for the two 27C512!

Best Regards,
