Help: Safe for Full reflash?

[Sledhead]

I am set to flash in my DSP5 operating system. I don't have a bench harness and documentation strongly advises isolating the ECM from the class 2 network with a star connector (?). I'm searching for solution but can someone advise me? Thanks, Rod

I've never done anything special. Just click the full flash and make sure radio,lights, etc are turned off.

Shut off radio heater anything that drains power

I've done hundreds of full flashes and only killed one ECM
u should be fine

Ok thanks. Here it goes...

The full OS and calibration option is disabled. It will let me read pcm, flash the calibration, but not the OS and calibration.

I upgraded my OS very carefully following the instructions and confirmed the right script (late LB7 metric). I used Socals scripts to populate the tables from different tunes. Is there a permission I need to enable?

Do you have the V2 plugged in before opening efi live?

 

[Sledhead]

No, I'll go back and do it that way...

The way I normally do it is key on, plug in V2 to truck, then to laptop and open the efi live program. There are features that aren't available unless you have the V2 plugged in prior to opening the program.

Thats all it was. New OS and calibrations are flashed. Truck runs fine but I didn't notice any change (at idle) from tune to tune. I'm going for a drive...

It seems to be working, the tunes are pretty similiar but I put a smoke tune in the last calibration and it smokes on that one lol. Set an overboost code on at least one of them too, 28.5 psi on my max hold guage. I'll need to fix that. Thanks for the help :hug:
