    You will need the flash connector to read or write roms

    Thanks Martin

    Can you confirm if this ROM is virgin or has been tweaked in some way?

    I've just checked it against 2 other N/A SOHC V6 ROMs I've got that are known-stock and the MD5 hash is different (meaning the contents of the ROM are different).

    No problem

    As far as i know its virgin ROM, i dont did anything!

    And i dont think anybody before me too..

    Would ecuflash stop us from dumping if we choose the wrong model, ie 7203F instead of FA?

    Here you go... more to come. Will disassemble more, there's plenty to define - but this should get you started with the bare essentials.

    Found by Disassembly:
    • Low & High octane Fuel map
    • Low & High Ign Map
    • Cat-Warmup map
    • Immobiliser Code - use bit3 of periphery0 to disable immobiliser completely

    So tomorrow is the day where we reflash my ECU, im really nervous

    First we try the Immobilizer off!

    I have another thread where i plan a single Turbo mod, would it be possible to run bigger maps on my ECU cuz the NA Map only have 100% Load while Turbo is much more?!

    I dont know much about mapping right now, a mate would help me but his and mine question is, is that possible?

    greetings

    Hey,
    flashing works but we had to change the xml a little bit.
    It's not 7203FA, it's only F. Our fault.. Than we were able to write the new rom to ECU!

    greetings

    Wow blast from the past

    I dug up my old N/A defs / ROMs earlier, it's something I'd be interested in doing at the tuning day in a couple of weeks as it's more of a challenge.

    you could add:
    AirFlow MAF Hz Base Table
    MAF Compensation Table
    MAF Size
    MAF vs LOAD? (This to me the most important)

    ?

    Hi All,
    I know that thread is quite old, but didn't want to start a new and similar one.

    I own EA5A from Europe - 2.5 V6 6A13 engine (no turbos). It has a 7203FA ECU in case MR507734 (EM2434) and H8539FA memory module. I am able to download/upload from/to ROM and I used definitions I found in this forum but some data and scales were displaying incorrectly in ECUFlash. As I was able to fix the scales addresses (I based on other definitions and ROMs from here) I am unable to find correct data for some. My question is if some can take a look at the ROM / defs. and help me find the correct values and maybe there is some more like data from knock sensor.

    I will be very grateful.

    You'll want to try the Kenneths 1.03 definitions. They work well enough on stock VR4 ROMs.
    The more you know, the faster you can go. And I still don't know enough.
