another erased ecm

Unread postby p4ndiamond » Tue Oct 02, 2018 1:08 pm

Not sure what's going on. But I use the mongoose to do my loads on my eec v. It's a 1998 cobra Aol3.

I plugged up to it the obd 2 port and USB on the computer and asked be to write to the ecm. It did not detect it and fans and pump were running. This is normally how it starts out for a load. So I power cycled the key to prepare the erase and write. Keep in mind it has not touched the ecm yet. The fans still came on and the pump. So I unplugged the USB and obd2 from the car with the key in the off position. And now the ecm behaves as if it's bricked or erased.

Not sure what happen since the mongoose never wrote or erased anything. Is their an idea of what's happening I need the car so I wrote to an f3 moates to continue driving. The issue makes no sense.

As you know i had another ECM also the DDX4 one that did this also but it was never using the mongoose its always been the QH. it continuously would not work or run without a chip in the J3 port.

Suddenly one day that ECM just works without anything in the J3 port after more than a year of not doing so. What the hell . lol .

Its a confusing and strange issue but i come to a final question here. If the issue is that the ECM data on the ROM is somehow corrupt etc. is their a way to push firmware to it even if the mongoose does not detect these ECM ? i have bin files i can push back onto them .

impossible to brick a ford ecu they flash over hardware not software

yea, just force a write, if your using pcm flash select recovery in settings and u can write anything to it

if the software your using wont let u manually select the ecu type or do a forced write then your SOL

if you try to access any upper level aice functions while the j3 port is overwritten then your aice chip will go in to lala land and u have to remove power from the ecu to reset it. Its happened to me a few times when i go to flash or read an ecu not knowing it had a chip on the j3 port.

Had an ecu get erased on me due to an error in BE. BE will say it doesn't detect an ecu if you try to reflash it, but will give you an option to do a recovery reflash. Unfortunately it costs an additional token. Maybe contact Clint or Adam and see if it's something they can help you recover since it may have been an error on the BE side. They covered the additional token in my case since it was the softwares fault.

Interesting. For mcc does it need the dongle to flash through mongoose? Same with pcm flash.

For 2015 up tunes are using tuner pro rt for that?

Update on my situation.

This is the 98 cobra aol3 ecm.

I was on with core remotely. They sent in a token but the mongoose still does not detect the ecm is key on to even write a fresh copy to rom.

I unplugged the ecm for 24 hours and this makes no difference in the condition.

I saw a thread where you were talking about the aice chip. Is it possible this is still hung up and preventing detection? Any way to test pin 13 on the ecm to verify if it's good or bad for what ever reason.

I recalled you saying a conflict between it and the j3 port took hours to recover from. What did that entail?

yes mccflasher requires the dongle to read or write same as pcmflash

pcmflash wont show what modules you have though unless your dongle is plugged in, mmcflasher will show u what modules you have though with no dongle

98 cobra ecu is craj0 which is a 4 bank, you can read it and write it with pcmflash thats what i do

you don't have to detect the ecu it won't since it can't communicate if its blank, just go ahead and select 4 bank ecu and write it, BE used to allow you to do that don't think its possible with a database though.

no the aice chip cannot get hung up like that. You will know very easily if the ecu is erased if its not it should fire up on the stock tune or what you wrote to it???

if you try to read or write through the obd2 port with the j3 in use then the ecu will freak out. You can remove the chip disconnect power for 30 minutes and all is well.

If your referring to the one time I disabled the aice chip in the tune then thats completely different as I intentionally shut off the obd2 port experimenting.

Thanks, ill see about picking up the PCMflash software.
I am not familiar with it . Do i have to purchase a dongle to utilize it or does the email allow me to use my BIN to flash it even without the dongle.
By the time i get a dongle i likely wont be home and ill have to wait another few weeks.

That makes sense also , regarding the j3 port being in use. I never had that situation.

Is their something in the mongoose that would cause , simply plugging it in to erase the ROM ? I just don't want any repeats of the current situation. The only other thing they found was that it had an older firmware or something on it.

when u purchase it they send u the dobgle

no way the mongoose cud unintenionally erase it, the obd2 port needs the correct seed and key to erase
