Default Need help from those with GIAC chip knowledge.

I bought a "GIAC chipped A box" from the classifieds and the ecu was DOA. There is water damage evidence. Also the actual chip and it's placement are suspect to me. Tell me what you guys think.

This post in the archives has pics of where GIAC places their chips compared to ams/mtm/abt.<ul><li><a href="https://forums.audiworld.com/s4/msgs/1393696.phtml">https://forums.audiworld.com/s4/msgs/1393696.phtml</a</li></ul>

Default I put it on my MTM socketed board and it worked but timing never went above 2 degrees.

The car is very slow.

Default the chips location looks fine...that doesnt mean there couldnt be a bad solder

connection causing a problem or perhaps the blacking locking rings is not fully seated. Although water damage cant be a good sign. Do you have any pics from the sides ?

It requests over 1 bar of boost, but I tried an XRV07A chip in the board and it woudn't start.

Default That looks like the proper encryption board...

Look for a glue-covered chip on the flip-side.
