Thank you as well 87Turbo.
I did see your post, however, I need a stock chip as I'm using the ECM as a test bench for some development work.
Turns out Rumblebee's ECM does come with a stock chip, so I'm going to grab that one.
Now I just need the Calpak chip. I'll post separately for that, as I suspect you wouldn't want to sell this chip separately from the ECM you have listed.
All the best!
