Hello,
I recently sold my E30 and found a couple things in the glovebox from the previous longtime owner.
One of the things I found is a BavAuto performance chip for a stock 2.7L ETA (not SETA or stroker).
It's probably 10ish years old, but I assume it still works.
Since it is a 24pin variant, I think it only will fit the original 027 ECU.
Here is what I found on BavAuto: https://www.bavauto.com/d900-2711
$75obo USD shipped
