I've always been rather succesful with recovering ECU's for people, so it's unusual to be asking for advice, but here goes!

I've got a tprotected EDC17C46 unit here, that's apparently dead. Indeed in the car that's how it behaves, we get the fans on, relays click wildly, no boot no management light, no communication and of course, no engine start.

With the ecu on bench, with bootloader (genuine Kess), the processor is able to communicate with tool, and we are able to read and verify the contents of the microprocessor, and also perform a write. I've been given a backup file so we have tried rewriting the lot to no avail, which to be honest from the relays clicking I wasn't expecting to be effective anyway - it's always an ominous sign!

My gut feeling is that the boot pins, which according to the respective datasheet double as the hardware config pins have been shorted whilst the ecu has been soldered - or something along those lines and I think the processor is internally damaged.

I've done the usual checks regardless, check for pcb damage, contunuity of pins, i've even resoldered the processor in case there was anything the eye couldn't see, but to no avail.

So, bearing in mind the chip seems to contain some OTP areas (well, as good as OTP anyway) I'm looking at my options - I can source another ecu but i'm prepared to invest somewhat as few seem to work with these yet (from a recovery point of view anyway), so this is a fantastic opportunity to get down to the nitty gritty with these types.

I'm wondering if anyone has opinions of a good strategy to save this ecu - I can get a replacement but i want this alive even if it then spends the rest of its days on the bench in a development role -my next plan of attack really is to replace the microcontroller as a whole, i'm just concerned that the controller will have a serial code onboard which will prevent all the (usual) approaches to cloning. It just seems too easy (if you consider soldering a near-100 pin chip easy :lol: )

I never scrap an ECU so...Any thoughts?

for the moment edc17 no can clone
when you read edc 17 no read all micro only part
1 little part its impossible for the moment read
sorry for me bad english :crazy: :crazy:

that's allright - turned out to be a hardware fault with ecu (not the processor) - we replaced the ecu in the end.

Bit of a faff but all sorted. :)

It's been some time,
does anyone have new information on EDC17 clone?It is possible?

Some ECU's can be cloned with X17 tool. With regards to your ECU OP... it sounds like its stuck in boot mode, you could have got used ecu and moved processor across but its not the easiest :)

that was the problem eventually, though proc itself seems ok, so board problem perhaps keeping ecu in bootmode.

It isn't all bad news :)

Did you test start the car after opening ecu, before you started to work on it ?

+1 very good question.

of course.

I still have the ecu which I now use as a testing unit because the micro still works (ish) even if it's useless as an ecu. I keep going back to it have a gander (it's been long since replaced) and long story short it's stuck in bootmode, so it's more than likely an IO pin has succumbed to ESD not on the first opening but on one of the subsequent programming sessions, or alternatively the board has fractured on one of layers.
