4AGE 20V ROM

[jonsole]

Hi, I've upload the 2 4A-GE ROMs that I have. I only kept a record of the chip numbers in the ECUs, so I don't know for sure if either of them is for the 20v ECU. The one labelled D151803-7990 is from the later chip so that's the most likely one.

Thanks. As far as the 20V's, my silvertop chip is D151803-0360, and I believe D151804-8081 is (one of) the blacktop chip(s). I guess there are different revisions and differences between auto and manual trans, different regions, etc.

I'm now 100% sure D151803-7990 is for some 4A-GE 20v variant as I found some old messages from the twobrutal forum.
I was sent the ECU to fix leaking caps and to see if the ROM daughterboard would fit. It didn't but I extracted the ROM image whilst I had the ECU. It was a Silvertop ECU.
