'01 to '03 Gauge Swap. Doable?

[KevinH1990]

Gavin,

I sold my EPROM programmer to another board member and he is working on a Model Year 2001 gauge cluster. I know that the EPROM on the old cluster is a 16 bit 93C56. What is the chip on the newer clusters?

Hi Kevin, the chip is a 93c86. The reader you bought will read this chip, and the clip will fit it fine. It will be byte swapped as before.

I've learned a fair bit more about the structure of the programming and have managed to fix my fuel gauge error now. I've just bought a Durametric cable to turn some functions on and off so I should have more information through that as well.

I'm happy to talk to the guy that bought your programmer, or send you the data if you want to talk to him direct. I have a much easier method for making the cluster work now.

I'l post it up here once I am sure I understand it completely. I totally confused my cluster a few times whilst learning and I don't want to give people incorrect information that leads to broken clusters.
