    Hello,
    I am trying to Read and Write a Sirius32 ECU from Renault Megane 1.4 16V (W/AC) on the bench with Galletto . It stops at 75%... Any ideas please?

    This ECU is easy, unsolder the flash and read in a reader.
    Bootmode is only for 32N not 32
    If you only want to map it then you only need the 32k maps (Non bootmode)

    Thank You Shooting!
    I have tried to unsolder the flash but it is stuck for good on the board. I used special solvent, various cleaners and acceton. Used hot air up to 450 C. but it would not move so I gave up because next step would be damage to the board...
    I have put the ECU back on the car and tried via OBD but got the same result. Stuck at 75% .
    So I gave up for good and are left with the question is it my equipment or was it the ECU...?
    I guess I will know next time same type comes along.
    Best Regards

    It is attached with a small click of glue, therefore it is a little difficult but not impossible.
    When all the tin has been solved [hot] tends a bit so it releases.

    This ECU is best read by a Galletto1260 via OBD, then you get the 32k Maps.
    What do you want to do with this ecu?
    If the car starts then the ecu is ok and it'll be your tool that's got a problem

    No glue on these 28 leg chips, they have lacquer over the pcb which makes it difficult to heat the legs

    Thank You guys!
    @ Shooting
    I have also tried 1260 via OBD but it was even worse... It kept on reading ID without any results. This car has been immobilized and wanted to read full flash in order to do Immo Off.
    And yes You are right about the laquer that I cleanned easily all around the legs and top but under the chip there is no way i could do anything.
    Anyway there was OBD connection with Diags so the ECU is not damaged but that was about it.

    Best Regards

    Yes You are absolutely right, sometimes it gets wrong when I think

    There is an Immo off tool for this ECU, I have one, it runs on the bench and removes the Immo, not sure if you can still buy them, eBay would be a start, this will save removing the chip.
    You can't do Immo off by OBD on this ECU has to be full read as the Immo is in the boot sector and OBD doesn't support it.
    Your only cheap way is to remove the chip.. use a hot air gun with the nozzle removed to give a bigger air pattern, or buy a tool.
