cant flash an 07

[relay93]

start to finish - read pcm with v2, did not notice i had 601 boot loader. made all mods to tune & blew file in. truck had no crank situation. i then reinstalled original tune & started truck. loaded h&s tuner in truck & road tested, brought back in shop & returned pcm to stock with h&s tuner, i then flashed in original efi live tune & all ok, i did not reread pcm at that point to see if boot loader had changed

Thanks for the reply

so i wonder if that would work on a 2010?

That is a good question, but I don't think so.

i didnt figure it would. i did use the h&s trick today to get around the bootloader in this thred. worked just fine.

So using H&S...you loaded a tune from them, returned to stock, then you were able to read the stock file and flash a EFI tune into the ECM??

It's a different ECM with different security measures, so it won't work

Les,

I have been doing this with smarty but I read ECM First and save that tune to go back to if needed and use an 09 operating system non 601 bootloader to build a tune from. The smarty changes the boot loader.

The reason I keep the smartys one for 5.9 and one for 6.7 is to adjust the speedometer. Again read, save, program with smarty, adjust speedo, return to stock with smarty, and speedo setting stays then build tune with previously read file or obtain a clean file if needed and flash in and speedo is accurate and truck is properly programmed

I,m having trouble with anti tuning fault then flash aborts. Tried to load h&s then return to stock with no luck still wont let me flash it , the h&s works fine when loaded. Any help would be appriciated
