    Thumbs up A little surprise

    We just thought we'd surprise everyone in the next beta release (posted HERE). We have added in to the V8 software the ability to read out the Bosch E55, E69 & E77 ECM's.
    This is an exercise to assess interest in these ECM's and for us to evaluate how difficult they are going to be to add support for. Being Bosch, I think I already know the answer to that

    First one is the E69 ECM, this has been used by GM for the Direct Injection 4cyl and V6 engines even up to today. It is currently being phased out in favour of the new E39 ECM (which we already support). However, the E69 was/is used in applications like the Turbo HHR, Camaro V6, Holden SV6 and some Cadillac's.
    The E55 & E77 is used on the 3.6L non direct injection HFV6, cars like the Cadillac CTS, Holden Commodore, G8.

    We've tested reading on a number of different 3.6L ECM's and it works fine (06 VZ Comm-E55, 08 VE Comm-E77, 08 SRX-E77, 09 STS-E69), it takes about 12-15 mins, but we are at the mercy of Bosch's limitations there and we are currently reading out the entire ECM (OS and cals) so it does tend to drag on a bit (compared to Delphi ECM reads).
    Now the beta release is posted, if you have access to a vehicle using any of these ECM's we would appreciate if you could attempt to read the ECM, if it works, please Email the tune to support@efilive.com, and if it fails, please Email support details about the vehicle so we can get a picture on what models this might work on.

    Thanks,
    Ross

    Great to hear, hopefully down the road tuning support will happen. 15 mins, better hope the battery is fully charged before trying to read it!

    15 mins is good for Bosch, it all comes down to how much they (Bosch) limit the read speeds, it's a very different process to where we can use our own bootloaders for the reading, this is not possible on Bosch systems.
    For example, these Bosch ECM's have 2Mb of flash with a 15 minute read time, on the E39/E78 they have 3Mb, but we are reading them using EFILive's own bootloader..............in about 2:15, crazy.

    No chance, same hardware, but different in many ways.

    No, same deal with them, we are just sticking with Bosch as used on GM.

    OMG Ross, I'm crossing my fingers that I might actually be able to tune our '09 CTS 3.6 SIDI!!! I just read it out and it seemed to read ok, also read out the T43 but that's been readable and editable for awhile now. I'll email you the file to see if anything can be done with it.

    Thanks Ross!
