reflashing > is it that simple?

[wrxsti]

Hi all.

I have a basic question which I would like to know before wrecking a ecu.

Using Ecu explorer, I have read the ECU flash memory of a friend's EUR MY05 WRX with PPP. (..cpu.hex and ..tpu.hex file)

Can I use these files to simply upload these using "write rom image to ecu flash memory" in a standard MY05 WRX to give it PPP?

If yes, do I only need to upload the ..cpu.hex or also the tpu.hex?

Many Thanks in advance guys!

P.S. If this is the case and anyone is interested in a "cc" of the PPP ecu file, let me know!

A couple of suggestions:

Are both the ECU's the same model number?

Make sure you read and save the non PPP ECU before flashing it - that way you can always put it back to normal.

Are you in the uK?

Cheers

Edward.
