2011 gmc 2500 hd bootloader rejected ?

[joecar]

Just checked again,up to date

Pulled the ecu out and it is a E 78,Not good EFI dose not support E 78,they have 11 truck for tuning and all are the same 2011 GMC with the 6.0,can HP Tuners tune E 78 ? Tuned 2 older trucks they have and got 2/3 mpg

Here's the document Paul mentioned, read it carefully before proceeding: Upgrading FlashScan.pdf


You only have to upgrade your V2 firmware from one PC only (not 10).


Read the document and do exactly what Paul said:

...

The most important thing to get right during the upgrade process is to make sure you get the firmware to exactly V2.04.72 before attempting to upgrade the boot block.
If you attempt a boot block upgrade when the firmware is V2.04.70 (like yours is now) or V2.04.71 then chances are the V2 will become unresponsive and you'll need to return it to EFILive to be reset.

The document explains the steps you need to take in more detail, please follow it carefully.
...

This will give you E78 ability.

But I mod tunes all over the us and it will not let me if I goof up,I have 2 truck from NY City next week.This is what I mean when say (It is getting hard) I update a lot of things over a year and none of updates are do or die,I just don't want to be without it for ? 2 weeks

The firmware update is a matter of minutes. They (EFILIVE) have even put in features in the help tab on v7 and v8 to check for updates. If you aren't running updates, you will not have the cal files for late model products.

This is not in any shape or form a fault of efilive, they are expanding support and making our end product better. To accomplish this, they must implement updates to allow us to move forward.

Follow the update instructions and you'll be just fine.

I also tune stuff from all over the nation and I couldn't do it without these important updates.

Once you install V7 build 211 and V8 build 203, the Check Updates feature works...

and once you get your firmware and bootblock current (carefully read the document, takes less than 5-10 minutes to perform), V8 will also update those in the future.

[joecar]

To use EFILive on any PC, just install V7 b211 and V8 b203 and you're ready to go (once V2 firmware was updated and BBx configured).

I update once a week my EFI ? Have all the new ecu's cant find the V2.04.72 update,maybe I don't know where to look ?

[joecar]

I update once a week my EFI ?

The software may be updating (the update feature was recently enabled)...

but the firmware could not be updated until the bootblock was upgraded (see doc mentioned above).
