4AGE 20V ROM

Hi there. I remember back in the day following your thread on one of the MR2 forums (which one was it again?)
I remember you extracted the ROM from a 4AGE 20V ECU. Is it still accessible anywhere, or is it possible to post it in this repository?
Cheers,
Dan.

Instructions

Hi,
I just found this repository and I find it really interesting. I have an E36 with a 2JZ GTE VVTI engine from a JZS161 Aristo and I was always curious how these aftermarket daughterboards work. These ECUs respond pretty well to hardware changes, so if you could remap it for bigger injectors it would already be super useful. Do you have any further information on how to install the daughterboard and how to extract the current binary and program section?

I have done quite a bit of RomRaider development, maybe we can start a definition file for this or other Toyota ECUs? I could also integrate the checksum algorithm directly into RomRaider or add other custom code to make this work.
