I'm Back!

complete success!

In summary I bought a 996 blue, green, grey connector cluster and put it in my 03 boxster with the same color connectors. I added a wire and a new oil pressure sender.

I discovered that my gas tank was empty when the gauge read 1/4 tank. After considerable research I found that my 996 cluster was coded for a 4wd car that has a different shaped fuel tank.

You can read this entire thread to see what I tried but here is the answer:

A forum member gave me a BIN file of his working eeprom and I flashed my cluster with it. Now my gas gauge is spot on.

I believe this is one possible solution to the gas gauge problem with C4 clusters into a boxster.
I also reason that this will probably work for any 996 cluster 2002-2004 with the blue, green, grey connectors.

O.B.
