Default Difference ECUs 89661-50241 and 89661-50240

When I first got my 1UZ it had ECU 50241.

Since then I have screwed up 3 ECUs.

Could not get hold of 50241 used 50240 in stead, to me seems the engine
is running just fine with 50240.

Although, I wonder if somebody knows the difference between the two.

The last number on the toyota part number is the supercession number. So the 241 is a later replacement for the 240. They should interchange without any issues.

What happened to your ECU's? I fix GM ECM/PCM's, I could take a crack at it if they are sitting collecting dust.

Collecting dust they are.

I have my 1UZ in a boat, the boat sunk, twice.
The ECUs didn't work after that, no surprise really.

One ECU sat on a shelf for 6 weeks, while I was out of the country, hauled the engine before I left.
When firing up again after returning the ECU works but only for 7 cylinders.
