What chip is it what company? I have ECU tune 1.5V..mine does not look like that . yours i think is a factory one . my install instructions says to rermove it to add the ECUtune . The factory chip they show is 22677AA040 F23AVH06

I am trying to check it out . Some of the earlier SVX did not have it , there was an empty socket. It is used to up grade things in the engine management . What I don't know

I had a chip in mine as well. Is your SVX originally from Canada like mine?

I guess you can't buy them from Subaru so a guy made one .It is 3 times the size( memory ) and it is mapped / programed on a dyno. A little better than the stock one and a lot better than without a chip. . You are lucky you have one

That is a factory ROM. I ordered one 5 or so years ago as it was the easiest way to get SVX ECU firmware at the time. Of course now you can use the ECUtuner interface to download the firmware off of any OBD1 Subaru.

That firmware is the basecode the ECUtune modifications are added to. It in itself doesn't offer any real performance enhancement--the ECUtune Stage1Av1 of course does.
