Write entire issue (Cooperhead ECM, stop at 74.2%) and start issue now !

[Dontov]

Hi,

After a couple of change on the lastest tune, i try to write entire, and it failed at 74.2%,
i tried 10 times or so

Here are all the check i done :
- check battery
- check PC battry
- check all light off
- put charger on battery
- pull battery 20mn before reconnect it
- disconnect/connect HPVIpro
- disconnett/connect USB cable from HPVIpro
- test 2 usb port on PC (PC is the one i use for tune)
- install "Latest stable version" (5.0.4.0)
- try to put stock tune with in "Write Entire" mode ->74.2% issue
- after "Controler Unlocker x11 Service Not Supported" :
key off
close car
open car
key on
test again
- try to put last good tune (with no P0605) with in "Write Entire" mode ->74.2% issue
- try to put last tune (with no P0605) with in "Write Calibration" mode ->Write ok, but not able to start and a lot of Ford messages at key on
- since Ford messages appears, valid "ok" at followed Ford message after each "key on" :
Hill Descent control FAULT
Remove objects Near Passenger Seat
Service AdvenceTrac
Low Oil Pressure
Engine Overtemp
"Key" logo
(and put off home Ford GPS/Radio/CD screen)
- re-done a lots of try "Write Entire"

i cannot gather info or read tune now (i think since i tried and succeded to "write calibration only" a no 0605 tune), as the ""write entire" done before with error erase the tune)

Completly lost now

(i think i read all the "Cooperhead ECM 74.2% issue",
i email support also,
but if somebedy can help...)

Best regard

Solve,

As read issue at 74.2% seems just the voltage check,
don't know why all was ok in 2018 (same car, same Ford options, no electric stuff installed, just different VCM suite version), but now, i had to unmount the ECM from the vehicule to pin it directly to the HPT OBD2 connector,
hope this help !
