A little update:
After doing some research here and there, I found out that some people manage to get a similar ECU which is the
9717580-129-7 by denso. As far as I know, is the same ECU as
89661-60250 and should get the job done, so I bought one of these
9717580-129-7 ECU (which the seller said it was for a 2lt engine) and bought it anyway as I thought that would be no problem based on other people results.
I plugged the ECU and it seems that the ECU can detect and control almost everything as it should but the only problem is that it cranks but it won't start... So I'm wondering if the ECU (
9717580-129-7) may be defective (maybe some capacitors leaks?) or maybe it actually doesn't work for the 3lt engine (but that kinda doesn't make sense since this guy manage to have great results:
Looking for ECU for my KZJ 78 - [Leaving Land Cruiser Club] ). At this point, I don't know what should I do next.
If anyone could tell what could be causing the problem it would be great.
Here are some pics of the
9717580-129-7 I bought:
