(diffrent exhaust regulations and perhaps diffrent mapping for those reasons?) yes you are right, but as minimun the ones for the same car model are adapted for the same engines and "engine accesories", and i gues the ecu external circuit can be adapted, example the ecu AT ones can be deceived to work in MT cars, but not the MT ones in AT cars..
the easiest ecu requirementes on contamination controls are the ones for less controlling countries, south america, africa, etc..
after a search in the EPC i understood that your chassis version is SQ625W-3 , is the only one employing your ecu part number..
Hi Pancho, thanks thats a great tip. Where is sz? The only thing I can think of is diffrent exhaust regulations and perhaps diffrent mapping for those reasons? I will however start searching for those numbers asap.
Hello, new to the forum and thought i´d bring this thread back to life. I have the same ECU problem as Ray with the same ECU. Partnumber: 33920-52J21 (33920-52J22 is a later replacement and also works). I´ve looked everywhere and even paid Suzuki Sweden a whooping 2300 euro to order a new ECU, after two weeks they got back to me and said this unit can nolonger be ordered.
So I´m quite stuck atm. Im talking to repair shops and have ordered a simular ECU from a guy in the US that has the exact same board but with only small amount off diffrencies to it internaly. And ofc it has a diffrent map. Hoping some skilled guy can help me move some critical parts over to get a complete working ECU.
Right now im considering all options. including buying another used car with the 2.5L V6 or 2.7 V6 and steal everything regarding engine control units and key / Imo and so on. Or even switch engines just to get this thing moving forward. The car itself is in to good shape to scrap.
Is this 2.7 ecu? Apparently you can tune the 2003 xl7 or vitara v6 ecu. I just got some software and hardware saying this. I only have one ecu at the moment but soon as I find a 2nd I will post vid or a few pictures
Naah, unfortunately i did not find a good work around or alternative solution.
I had to do some thorough investigation and checked all Grand Vitaras from the same year and with the same setup as mine with the Swedish department of transportation. By doing so I managed to track down a couple of vitaras that just got delivered to different scrap yards. After a couple of phone calls i found one that were not demolished and managed to buy a used one with the same number. The final step was to have a guy reprogram it. It was still possible to load the data from the drenched cpu.
To good thing about this is that i now have an almost complete list of all Grand Vitara 2003 manual v6 in Sweden ;)
Good luck with your search, these cars are to good to not try to save!
Best regards,
Gustav
And... Don't forget to build a small 'roof' for the new ecu if you manage to get a hold of one.
If the numbers on the processor is the same then they should have the same code. Some of those ECUs can't be re-flashed but if the processor is still good then it can be swapped onto another PCB with the same number.

If the numbers on the processors are the same and i clone the ecu (this is a bit out of my league, a company here in Sweden will do it for me if i find a suitable ecu) will this overwrite all the code, or does this cpu's have a part of the code that are not possible to overwrite?
I totally understand if it is impossible to answer my question without testing.
They probably have different code. what are the numbers on the processor? Also check that they have the same components fitted. Unfortunately the clogged AC issue is a common problem.

This questions concerns a Grand Vitara 2003, v6, manual transmission.
So, I got my ecu (33920 52j2 1) drenched by a clogged ac.
I have found an other ecu with a different Suzuki parts number (33920 52jj 2). But, they have the same Hitachi number on the boards (GE222848 A).
Are they the same board in all essentials? If so, how come they have different part numbers? Region?
I also found some indications that 33920 52j6 0 might be the same as well. Does anyone have any inputs if that might be the case.
Since Sweden is a small country with few Grand Vitaras it would be extremely helpful if anyone could guide me towards an ecu from a different region that would work.
