I'm able to read the AYC Ecu. I readed a stock one and a Ralliart. I also can write then how i wish.
I'm working in the chiptuning company and i have a tool that makes also this ecus.
Unfortunately, i'm in Romania which pretty far.
But if somebody really wants, i can write anything that he wants inside the AYC ecu. I will also post a bin file of a stock ecu for the dissansembly guys.
NOW
Ralliart has 5 types of AYC ecus. I put my hands only on K2 model which is for gravel rallies.
Did anybody used something different??? I'm curious which is the best AYC variant for road?
If somebody has any ideas, i'm opened to anything

How did you read out the ROM? What interface are you using?
Did you know what processor is used in the ACD/AYC?
Is the ROM placed in the processor flash ore external flash?
So many questions

Hello,
I did readed it out using a serial tool (i cannot tell you the name of the tool because it is company secret)
Inside you will find out a MH7203FA processor and from what know, the rom is inside the processor.
And i needed only 2 wires to read out the rom, and 12v and ground.

MH7203FA would make it the same processor as a 1998-2000 Eclipse, as near as I can tell; ie. an H8/539F.
From doing some beginning work on disassembling a 1999 DSM ROM, IDA Pro's H8/500 processor module seems to do the trick for it, if anyone starts playing around with pulling the ROM off of it.

Looking at the EcuFlash website, the program supports all 2nd Gen eclipses 1996 and up. If we can get the ROM and create an XML then Ecuflash maybe be able to work, but we still would need a cable and maybe more code in EcuFlash.

I don't have where to post the file. Give me PM and i send you the file. Now i'm in a pursuit of as many different acd ecus that i can find.
Now i have the K2 from ralliart.
Or if somebody has place to keep the file, i give it happily.
Let's see what we can do with it.
I also have a lot of maps for Motec and Gems ACD ecus for the rally and if we find a way to understand the bin inside our ecus, then we can implement already used files
