FastECU

Hi,

FastECU has feature to use uj20 bootmode to flash bricked ECU. Note that sometimes it's possible that ECU is bricked for good and can't be restored.

Instructions to connections:

Then use FastECU with protocol sub_ecu_unisia_jecs_20_bootmode ...

I seem to be having same problem with newest version of FastECU. Im mot using tactrix, but scanmatik3 it does have the j2534 passthru and multiline k-line support. Does provide voltage to OBD PIN9 on initialization, but fails with same errors so im kinda lost and not sure what the problem could be ...

For the future, these ECUs uses bits for DTC groups, not actual DTC code from memory. If you need to remove air pump codes, it can be done for whole system with one change.

That recovery protocol is basicly sending many requests to connect to ECU, maybe working if ECU software starts normal. When ...

Hi,

You used FastECU? What version?

And what adapter? If j2534, is it clone or genuine?

For bootmode kernel write, MCU uses non-standard baudrate (39063) that many adapters fails to set.

These MCUs are bit weird, as they don't respond anything until you have kernel running, so you can't send any ...

Hi,

I want to ask, if I change some values in my patched ROM file (only some 10-12 values in one table) and after that I will flash it back to my ECU, how this program behaves? I mean it will flash only that changed area of offsets or it will reflash whole ROM file ? Thank you.

Hi,

It should ...

After switching to a Openport 2.0 clone the kernel now uploads properly and I am able to download the firmware.

Please be aware though that you have the EURO5 diesel listed has having K-Line support. I have confirmed without a doubt that K-Line support is non-existent on this car and does not ...

Somehow it can't start kernel. I need to check that there is nothing changed or missed during updates.

And some ECUs I have seen that VIN request does not return VIN, don't know why is that.

Also what comes to K-Line, it might work for logging but with reading and writing you have to use iso15765 as with K-Line you can't get into diagnostic (programming) mode.

ssmk_can_sh7059d_euro5.bin is for used with sub_ecu_denso_sh7059_diesel_densocan protocol
ssmk_can_tp_sh7059d_euro5.bin is for used with sub_ecu_denso_sh7059_can_diesel protocol
These kernels differs the addresses they are loaded and also CAN setup so can't be mixed.

What version of FastECU do ...

Well, after some time is gone... Can we flash ECU's with SH7055 350nm and 180nm versions?
EcuEdit have one kernel for both of them. I think EcuFlash has the same.

Yes, time flies :geek:

It should be possible to flash ECUs with same kernel as TCUs. I had no time yet to add them to same binary ...

I'm bit busy for few days, but try to look at this as soon as I have free time.

I think those 4 word values are used for data encryption, other set is for security access.

Great news! :)

Was just thinking what else could be wrong and only thing comes to mind is check wirings. Ground is always crucial between devices, otherwise signals are mess.

FDT should work with any adapter which could communicate standard serial speeds. Most of them won't do nonstandard speeds ...

Checked that TCU ROM and it has TCU ID in address 0x2000 instead of 0x3000 as some others.

And for the header, this should do to make it open in ECUFlash

<rom>
<romid>
<xmlid>WQDE2WB</xmlid>
<internalidaddress>2000</internalidaddress>
<internalidstring>WQDE2WB</internalidstring>
<ecuid ...

No connection, just says trying to erase, erase timer set to 121s, then you wait it out and it comes up no response.

When you say it sets erase timer, did the log say something like this? If yes, then it's connected to MCU, transferred the micro kernel and started flashing procedure but erasing ...

Yes i tried swapping tx and rx just to see if it made a difference, it just throws an erase timeout.

I dont know what you mean by rom headers or how to change that

But i am going to get a ftdi chip instead tomorrow and try with that, hopefully this one is good enough, way to expensive but the ...
