does any one knows in detail about this ecu???


Hello all,

could any one here help me identify the ecu rom and guide to hack this?

i think it has 68HC16, can anybody look into the pic attached and guide me to read and write this chip.

it is of suzuki baleno's. 1.6 ltr, 4cyl, NA engine.

my best wishes and regards to all denso gurus here.

regards,

SJpro

Any chance you could take a higher resolution (bigger) picture and one of the other side also?

Did you find out anything about this ECU? I also have one of these that I was going to try and hack.
Cheers

It looks very similar to a Subaru WRX ecu, do you have pictures of the backside of the ecu?

You might find it has some nice solder pads to connect a BDM

I haven't been on here for a while but I'm certain that this is a 68HC16. There are pads on the back that allow wiring to the BDM port. I've modded mine but not yet tried to read it.



Edited to fix links.

I'm still trying to get into mine. The Motorola drivers are written for an old PC (286/386) and there are two files, one for the PE interface and one for the public domain interface. You can work out the correct pinouts from the source code. I have managed to compile the source code using Borland Turbo C on an old 166MHz PC running Win95. The problem that I have is that the ECU is continuously resetting which causes it to drop out of background debug mode. It is difficult to debug with the DOS/PC setup so I am going to try using a microcontroller so I can control the timing more accurately. I think that there may be a watchdog timer running that is causing the problem, the reset is at around 100ms intervals so I believe that its too short to be a diagnostic reset. Hopefully I can get round this by commanding background debug mode and then issuing a stop processor command. I can send you the DOS executable file if you want to try it.
Cheers
James
